• trimming ends;
• thread cutting;
• reaming;
• turning surfaces of cylindrical and conical shape;
• grooves and grooves;
• trimming details.

Turning mini-installations for the home are divided by functionality and types of operations performed:

• screw-cutting, for example, Caliber STMN-550/35;
• milling, for example, a TV-4 school machine.

The screw-cutting microturning unit is equipped with a drilling chuck, with which you can:

• grind all kinds of details;
• make grooves and various recesses;
• trim the edges of the blanks.

On a screw-cutting machine, non-ferrous and ferrous metals can be processed.

The milling unit performs the following types of work:

• cutting grooves, both straight and curved;
• chamfering;
• drilling various holes;
• thread cutting.

Such a microlathe allows you to work not only with metals, but also with plastic and wooden parts. This is a more functional option for the home, versatility is provided by the vertical milling part.

Description of the design of turning installations

The design of desktop lathes for the home is slightly different from industrial prototypes. Some parts are smaller.

School machine TV-4 - drawing

The most traditional design has a school machine TV-4 and TV-9, the main elements are:

Lathe for home - how to choose?

In order to purchase a high-quality device that will serve for a long time, it is necessary to pay attention not only to specifications but also for specialization. Select in accordance with what work it is planned to perform on it.

More powerful models save time on processing the product, but also consume more electricity.

The weight of the unit plays an important role. Lighter models may be less stable and unable to perform complex work.

Asynchronous motor type is characterized by a longer service life.

Dimensions matter when working space limited, so it is better to choose mini-machines. If the area of ​​\u200b\u200bthe house allows, then it is better to give preference to larger options, for example, domestic Caliber models - they are stable and allow you to process them with a longer length.

It is better to give preference to models that can be upgraded and expand their functionality.

When purchasing foreign-made installations, it is necessary to take into account the possibility of repair, find out if spare parts are available for free sale, and if there is a service center in the city.

Video: How to choose a desktop metal lathe

Metal parts are constantly needed to repair a car. Well, if the model is common, you can buy it. If the car is rare, you either have to wait a long time until they deliver it, or order production. In this case, you can purchase a lathe for the garage. If you have experience, you can use it for part-time work.

What types of lathes are suitable for private use

There are nine types of lathes in total, but not all are needed in the garage. Most often, private traders can see small screw-cutting lathes. Along with the processing of parts (grinding, drilling, milling, drilling of radial holes, etc.), they perform various types of threading and taper turning. It is such a lathe for the garage that they are trying to buy - it covers almost all the needs of car owners.

Are issued in two types — desktop and with a bed (floor). Desktop - small, with low weight (up to 200 kg) machines. It is easier for them to find a place in the garage. The disadvantage is that you cannot process large and heavy parts on them. Another point: due to their small mass, they are not always able to give out high processing accuracy.

Floor lathes (usually school ones) have a much larger mass and dimensions. For normal operation, a separate foundation must be made under them. Installation on vibration dampers is possible, but it is not easy to find them.

Lathe device

In order to choose a lathe, it is desirable to know its device, purpose, functions and possible parameters of each of the parts. First, let's take a look at the main nodes.

These are the main components of the lathe. It makes sense to take a closer look at complex nodes, since the capabilities and operation of the equipment depend on their execution.

bed

Most often, these are two parallel massive metal beams / walls, connected by crossbars to give greater rigidity. The caliper and tailstock move along the frame. For this purpose, guide sleds are machined on the frame. The tailstock moves along flat guides, the caliper - along prismatic ones. Very rare prism guides for the tailstock.

Lathe bed for metal - factory and homemade

When choosing a used machine, pay attention to the condition of the slide and the smoothness of the movement of parts along them.

Front (spindle) grandma

The headstock in modern lathes, most often, combines a workpiece holder and a device for changing the spindle speed. There are several types of speed control - by moving the levers to a certain position, using the regulator.

The control of the regulator with a smooth change in the speed of rotation is carried out on the basis of microprocessor control. In this case, the headstock has a liquid crystal display on which the current speed is displayed.

The main part of the headstock is a spindle, which on one side is connected to the electric drive pulley, on the other side it has a thread onto which the cartridges holding the workpiece are screwed. The accuracy of turning operations directly depends on the condition of the spindle. There should be no beats and backlashes in this knot.

Guitar gears - to transmit rotation and change its speed

In the headstock there is a system of interchangeable gears for transmitting and changing rotation to the gearbox shaft. When choosing a garage lathe, pay attention to the condition of the gears and the absence of spindle play. This affects the accuracy of workpiece processing.

tailstock

The tailstock is movable - it moves along the guides on the frame. It is brought to the part, its position is adjusted, the quill rests against the part, holding it in the desired position, the position of the quill is fixed by turning the corresponding handle. After that, the position of the tailstock is fixed with another locking handle.

In some models, the tailstock is designed not only to support massive or long parts in a given direction, but also to process them.

To do this, depending on the operations performed, the corresponding equipment is fixed on the quills - cutters, taps, drills. The additional center of the machine on the tailstock can be stationary or rotating. The rotating rear center is made on high-speed machines, for removing large chips, turning cones.

caliper

The support of a lathe is a movable part on which tools for machining parts are attached. Thanks to the special design of this unit, the cutter can move in three planes. Horizontal movement is provided by guides on the frame, longitudinal and transverse slides.

The position of the cutter relative to the surface of the machine (and the part) is set by a rotary tool holder. In each of the planes there is a latch that provides retention in a given position.

The holder of the cutter can be single or multiple. The tool holder, most often, is made in the form of a cylinder with a side slot into which a cutter is inserted, which is fixed with bolts. On simple machines, the caliper has a special groove into which a recess is inserted on the bottom of the holder. This is how the cutting tool is fixed on the machine.

Garage lathe: parameters

First of all, determine the mass and type of connection. When choosing a mass, you should not strive to find the lightest machine. Very light ones do not give stability, they can vibrate during operation, which will affect the accuracy of work. Yes, it is problematic to install heavy machines, but installation is a single event, you will have to work regularly. Therefore, weight is far from the most basic selection criterion.

Too large lathes can not be installed in every garage, but small and medium ones are an excellent choice.

The type of connection - single-phase or three-phase - this is already more important. And then, three-phase can be connected to 220 through special starters. Of the electrical characteristics, engine power is also important. The higher it is, the greater the rotation speed the lathe can develop. These are common points. There are also special ones:

• The diameter of the workpiece that can be processed on the machine. It is determined by the diameter of the processing above the bed and above the caliper.
• Workpiece length. Depends on the move.
• List of operations.
• The maximum number of revolutions.
• The adjustment method is smooth, stepped.
• Possibility of reverse.

The dimensions of the workpieces are directly related to the dimensions of the machine. So here we have to look for a reasonable compromise. Usually you don’t want to clutter up the garage too much, but you need to process the overall details.

Micro and mini lathes

In order not to clutter up the garage, you can find mini or micro lathes. They are very small in size and light in weight. For example, PROMA SM-250E micro lathe for garage has dimensions of 540*300*270 mm and weight is 35 kg. It can process workpieces with a length of 210 mm and a diameter of 140 mm. Smooth speed control from 100 to 2000 rpm. For the size, it's not that bad.

Mini lathes - they belong in the garage

Despite its small size, it can perform the following operations:

• surface grinding,
• thread cutting;
• drilling;
• countersinking;
• deployment.

It is also possible to grind parts, knurling, tool sharpening. The main operations, as you can see, are present. The disadvantage is that you cannot process any large parts on machines of this type. And another disadvantage of this particular model is the price. This garage lathe costs from $ 900.

In the same category there are Chinese JET BD-3 and JET BD-6 (price $500-600) and domestic KRATON MML-01 (price $900), Encore Corvette 401 ($650), German Optimum - from $1300 to $6000 $; Czech Proma - from $ 900,

Floor options

Here the choice is not so wide, because both prices and mass are much higher. There are several proven models that can be installed in the garage.

These are the so-called school machines - TV 4 (its improved version of TV 6), TV 7 and desktop version TV 16. With a mass of 280 kg (TV 4) and 400 kg TV 7, it is desirable to have a separate foundation. If you just put it on a concrete floor, it will break it.

A garage metal lathe is an indispensable tool for repairing small metal parts. In total there are several types, but not all are suitable for a garage room.

There are many manufacturers on the market necessary equipment, which differ both in their dimensions and in their functionality. To facilitate the choice, we will find out which garage lathe is the most suitable and what you should pay attention to.

There are many turning units, in general they are divided into three types:

• desktop;
• semi-professional;
• professional.

Assembling a lathe with your own hands.

The choice of equipment depends on personal needs. The first two types are suitable for use at home, most often car owners prefer the desktop version. Their relatively small size makes it easy to place the unit in a garage and use for a variety of jobs.

Micro-machines have some limitations in use, the main thing is the size of the parts. Since motorists often work at home with small details, the option with a desktop unit is perfect for this.

The desktop lathe for metal, in turn, is divided into 3 types:

• turning and milling;
• screw-cutting;
• combined.

The first type is used when you need to remove chamfers from workpieces, make a hole and trim. The second type allows you to turn parts and apply threads to them, and the combined type gives all of the above.

Modern bench lathes for the garage allow you to perform several operations:

• turning parts of shaped, cylindrical or conical shapes;
• trimming the ends of parts;
• grinding;
• boring;
• drilling holes and expanding them;
• thread cutting.

Drawing machine for woodworking.

The home machine tool unit has several important advantages:

• take up little space and a wide range allows you to choose a device that can be installed in almost any room;
• reliability - despite the small size of the equipment, it will be possible to perform the necessary operations with high quality;
• ease of connection to the mains;
• low power consumption compared to large models;
• the ability to expand functionality by purchasing additional components.

Of the shortcomings of mini units, it is worth noting the most important one - a lower speed of work, however, such a nuance will not at all affect the quality of the work. Especially if the home machine is equipped with a CNC system - numerical control.

Lathe device

Before choosing equipment, it will not be superfluous to deal with its device. This will allow you to understand the purpose and functions of the main parts of the machine, which will help in the future when choosing.

Any design of a lathe for a garage includes the main components:

• frame - the base on which the remaining elements of the machine are installed and fixed;
• engine and gearbox - provide rotation of the spindle and caliper;
• headstock - serves to fix the object and rotate;
• tailstock - another fixation element;
• spindle - a metal shaft of the machine that promotes rotation;
• caliper - clamp of the cutting tool.

bed

The bed is the main part of the metal lathe, on which the remaining components of the unit are installed and moved. Often the part is made of cast iron in order to obtain a solid structure that can withstand heavy loads and last a long time.

Most often, the element is made in the form of two parallel beams, on which guides are provided for moving parts.

Headstock

The headstock, or spindle, is a cast iron box used for fixing. In addition, it contains a mechanism for switching spindle speeds.

The spindle, in turn, is the main part of the mechanism, on the one hand it is connected to the gear of the electric drive, and on the other hand it has a thread for winding cartridges and fixing the workpiece.

The spindle is the most important component, since the performance of turning operations will depend on its condition. In this regard, when buying equipment, it is important to pay attention to this.

tailstock

The tailstock also serves to hold the object of milling or turning during processing. It is a metal cylinder, firmly fixed on the body. In addition, in some models of the unit, the element allows you to attach various items: a drill, a tap, a reamer, and others.

The tailstock must meet certain requirements:

• do not move spontaneously;
• ensure a reliable position of the axis;
• facilitate quick installation along the axis of the machine;
• enable precise positioning of the workpiece on both center holes.

Garage Lathe Parameters

Scheme of a lathe.

When choosing a lathe for a garage, you should pay attention to its parameters.

In order for the equipment to fully meet the requirements, you should pay attention to the main selection criteria:

1. Machine weight and size.
   Here you should build on the possibilities of the garage space.
2. Ease of connection.
   It can be single phase or three phase. Since most often in garages the first type of power supply is 220 V, this item should be taken into account. It hardly makes sense to make separate wiring for 380 V for a three-phase connection specifically for the machine. In some cases, it is possible to adapt the machine tool to connect to a three-phase network.
3. Unit details.
   This point is especially important. You should pay attention to the components of the machine, especially the bed and caliper. They must be made of hard metal alloys.
4. Power.
   For mini-units, usually the power indicator does not exceed 2.25 kW. There are also so-called low-power equipment with a drive power of 0.15 kW. It should be noted that the latter are not suitable for processing large parts from durable materials. For the manufacture of nuts and washers, power up to 1 kW is enough.
5. Equipment.
   When choosing a garage machine, you should focus on its specialization. Having bought a highly specialized device, you can make a mistake. Depending on your needs, it is better to buy a machine right away with the necessary equipment in the kit, or purchase a basic package and, if necessary, equip the device with additional functions. The second option will be more economical, since you can buy additional fixtures as far as possible.
6. rotation frequency.
   This factor depends on the metals to be processed. It is better to choose equipment with a wide range of speed adjustments, this will give the owner more options.

Mini machines

Lathes, which can be classified as desktop, have a mass of 15 kg and up to 200 kg. For garage use, mini machines weighing no more than 50 kg are perfect. They can be easily installed and, if necessary, moved.

You should not choose the lightest and smallest units for the garage, as they can be unstable and vibrate when working with parts, which, in turn, will affect the accuracy of work.

Floor options

Floor lathes allow the processing of large-sized workpieces and guarantee high precision in the manufacture of parts. However, this kind of equipment has a significant drawback - large size and weight. In this regard, its use in the garage will not always be convenient and even possible.

For home use manufacturers offer desktop machines, with the help of which it will be possible to perform almost all types of turning work offered by the floor unit. The main difference is only in size.

Outcome

When choosing a metal lathe for a garage, you should pay attention to several factors. First of all, the dimensions and weight of the equipment are important. For a garage room, desktop units are perfect.

Despite their low weight, they act as a mini copy of a full-fledged factory model and allow you to perform high-quality necessary work. The only difference is the processing speed of the part.

Also, do not buy the smallest model, as this may affect stability. garage machine and will give vibration during operation. When choosing, be sure to pay attention to the power of the unit, its functionality, materials, components, speed and connection type.

IN conditions of limited space for the home master the best option becomes for the garage in the basic or advanced configuration. There are a lot of manufacturers and modifications of equipment on the modern market. Therefore, below are the recommendations of experts on choosing a mini-machine for turning metals.

Selection criteria, types

A metal lathe for a garage can save both the budget for operating a car, a household plot, and time. The search for small things, which is necessary for repair, construction, often takes several days. If you have the equipment, all this can be done on your own. The main selection criteria are:

• purchase budget - most often the basic equipment is purchased, additional functionality is purchased later, as needed, with sufficient funds it is better to choose a multifunctional (universal) machine right away;
• dimensions - approximately the same for most manufacturers;
• quality - it is not recommended to buy such equipment on order, it is better visual inspection, a trial run of buying methods has not been invented;

• desktop - minimal functionality, some models do not include a tailstock;

• school - different equipment, 2 step speeds with smooth adjustments inside each of them, reverse, weight within 200 kg;

• screw-cutting lathes - minimum spindle runout, high price;

It is very difficult to focus on the dimensions of the workpieces that can be clamped in the chuck jaws, placed between the centers of the stocks. The needs of each craftsman are different; from time to time, processing of large-sized parts or performing jewelry operations is required.

Specifications

A desktop-type garage metal lathe most often has the following performance characteristics:

• power button - may be absent (for example, for the Corvette-2 model), rotation is turned on by a rheostat that regulates speed
• dimensions - length 1.2 - 1.7 m, width 0.5 - 0.6 m
• weight - within 120 - 200 kg
• workpiece diameter - 10 - 20 cm above the bed or 5 - 15 cm above the support
• center-to-center size RMC - 20 - 50 cm
• drive power - 0.15 - 0.6 kW

Desktop device option

For a metal lathe for a garage, 220 V asynchronous or commutator motors are used. The designs of speed control systems, torque transmission to the screw support shafts differ significantly from different companies. In some modifications, the reverse is switched by a lever, in others, in order to obtain reverse rotation, you have to throw the transmission belt.

Most lathes only cut metric and inch threads in one direction. Of the domestic manufacturers, the most popular are “Home Master”, “Handyman”, “Caliber”. All other products, regardless of the brand's homeland, are made in China - Optimum, Corvette, JET, Proma, DIY.

For example, the Enkor company produces turning and milling modifications Corvette 407, lathes Corvette 401 - 403. Automatic support feed is used only for threading, processing, peeling is carried out manually. The chuck is equipped with straight, reverse jaws, parts can be clamped without a chuck in the centers. The smallest of them (Corvette 401) is equipped with a 0.5 kW electric drive, a speed of 2,500 rpm, electronic system, allowing you to maintain the same speed under any load. A through hole in the spindle allows you to process 20 cm parts.

Desktop device for metal Corvette 401

Optimum machines are equipped with 0.5 - 1.5 kW motors, the RMC reaches 40 - 70 cm, the height of the centers is 7 - 14 cm. The homeland of the brand is Germany, 95% of production is concentrated in China. A feature of the equipment is an error of 0.025 mm and 0.01 mm (displacement, spindle runout, respectively).

Desktop screw-cutting lathe by Optimum

Weiss desktop lathes have the lowest possible vibration, sound pressure. The spindle rotates in roller bearings; after the rotation stops, it remains possible to automatically reverse to move the caliper. The tailstock has a longitudinal movement with position fixation in space.

When purchasing a metal lathe for a garage, you should pay attention to the following points:

• manufacturer - products of domestic firms are easier to operate, since in the Russian Federation there are more service centers, spare parts, consumables;
• transmission type - belt or gear (the input shaft is always driven by a V-belt);
• gear material - preferably caprolon, which, unlike conventional plastics, does not crumble, but self-reinforces;
• the presence of roller bearings on the spindle - provides high-precision processing;
• type of guides - the resource of hardened machine elements is an order of magnitude higher, as is the quality of processing;
• revolutions - usually 0 - 1500 in 1st gear, 0 - 2500 in 2nd gear;
• the presence of several speeds - usually 1 or 2;
• protective devices - some models are equipped with plexiglass casings, which fade over time, split, reducing the view of the workpiece;
• headstock - preferably options with a through hole, allowing you to machine, cut threads on long parts.

Machine JET BD-8VS- belongs to the class of desktop lathes. The machine comes with a chip collection tray and is screwed to a cabinet or workbench through the tray. Despite its small dimensions, the machine is capable of processing a workpiece with a diameter of up to 210 mm above the bed, and if sharpened above the support, this diameter is reduced to 135 mm. At the same time, the maximum processing length (RMC) is an impressive 400 mm.

The rotation of the workpiece is provided by a 0.6 kW motor, a commutator motor, and these are one of the most reliable motors for desktop lathes.

A feature of the BD-8VS machine is the presence of a smooth speed adjustment in two ranges, the ranges are changed by throwing the belt on the pulleys. There are two ranges in total from 50 to 1250 and from 100 to 2500. Smooth adjustment allows you to choose cutting conditions for any type of material.

The machine can cut metric and inch threads; to change the thread pitch, you need to dial a guitar from gears. All gears are metal and have a good working life. On the turning "baby" you can cut 14 metric, yes - yes, as many as 14 metric and 12 inch threads. The machine will close any task when repairing the plumbing and any household item.

For high-quality and fast turning, automatic caliper feed, longitudinal feed is provided. In total, there are two feeds of 0.1 mm per revolution and 0.2 mm per 1 revolution of the spindle.

BD-8VS has the ability to sharpen cones, the 4-position tool holder rotates 90 degrees in both directions together with the upper carriage, this is the turning of so-called small cones. It is also possible to machine the cones along the entire length of the machine by adjusting the tailstock. What does it mean? We can offset the tailstock relative to the centers by +/- 10 mm.

The machine is perfect for those who like to do something with their hands, modeling, production, repair and just a favorite hobby!
