Homemade lathe for metal with their hands: instructions and drawings

Every home craftsman would like to have in your arsenal of tools for metal lathe. Such equipment makes it possible, if necessary, to carve the broken part, cut the thread, make some trifle, and more. However, since the industrial units not everyone can afford, and they have a lot of space occupy the majority of artists prefer to make homemade compact machines for their metal hands.

What can be done with the help of a mini-lathe machine, and where it is applied

Household mini lathe machines, as similar industrial equipment, intended for machining of metal and to give them a cylindrical, conical and spherical shape. Now almost all industries use CNC machinesThat allows to reduce human intervention to almost zero, but for household needs will approach a simple machine. Despite the fact that the compact turning equipment inherited from its big brothers most of the functions, however, it can be used to process only small blanks and parts. Also on the mini-machines can produce end trimming and boring, To carry out external and internal threading, boring and more. Compact turning equipment is perfect for garage, Home installation the balcony or small masterful.

What it is in the lathe: main components

For the most part, industrial and domestic lathes are similar. The difference is in the functionality, performance and weight. The figure below shows a typical device screw-cutting machine. The main components are:

• frame;
• support;
• headstock (placing the gearbox to adjust the rotation speed and the torque variation quantity);
• tailstock (for a more stable and reliable maintenance of the workpiece or workpiece clamped in the chuck (the spindle), as well as to set drills, taps, and other instruments);
• toolholder.

bed

One of the main elements of a frame - solid metal base on which are mounted all the major components and items of equipment. It must be strong enough and the mass such as to not allow the machine to tip over during operation. For outdoor version adds massive props (tables).

Caliper lathe

Caliper lathe is designed to move along, across and at an angle to the spindle axis cutters, enshrined in the toolholder. The device has a cruciform structure consisting of three main elements: the carriage and transverse slide incisal.

Making your own hands headstock lathe

Headstock is one of the most complex parts of the lathe, particularly for individual processing. It is the gearbox to the spindle and the control unit. Under headstock housing is a motor which belt drive is connected to a pulley gear.

This node is a block consisting of replacement gears for transmitting and changing the spindle rotational speed and torque with shaft boxes innings. You can buy a headstock lathe or make it yourself.

Tailstock lathe

Tailstock for a lathe metal is mobile and designed to clamp the workpiece to the spindle center. One of the elements of this site - the quill on which the fixed or rotating center resting against the edge of the workpiece. The workpiece is set in the cartridge is supported on the spindle and the tailstock. Thus, a reliable fastening to the details of its processing quality.

The tailstock can be installed drills, taps, reamers and the like countersinks When installing and moving on runners of the frame to avoid sudden and severe blows to the unit body to avoid bias centers.

Making your own hands the tool holder for lathe

The toolholder is designed for fixing on a support a lathe tool for metal machining and moves both longitudinally and in parallel direction relative to the workpiece. There are two types of tool holders: two- and four-way. In the first case, you can at the same time by means of screws to install two incisors, and the second - four, so you can quickly replace blades if necessary, without stopping the lathe. For a quick change of cutters, a special handle.

Manufacturing and device Metal lathes with their hands

To make their own hands a mini lathe for metal is not so difficult as it might seem at first glance. You just need to draw up a detailed action plan, drawing, to prepare the necessary materials and tools, and of course, some skills and a strong desire.

Design and drawing of the lathe for metal garage

This stage is the most important because it determines the correct execution of all subsequent operations and the correct operation of the equipment. The first step is to determine the dimensions of the machine. Average dimensions of the equipment used in the home, is 900 × 350 × 300 mm. Not worth much to deviate from these values, as this will lead to the fact that the work will be uncomfortable, and performance is significantly reduced.

Having defined the size of the drawing and a small lathe, proceed to prepare the necessary materials.

Illustration	Description of the action
	The bed of iron may be replaced by a frame of steel pipes and profiled parts. Do not use wood, as in this case, do not look for the longevity of the machine and the accuracy of the work performed.
	As the power unit is preferably a low power take the induction motor, since even with a sharp decrease of revolutions will not break actuator. Engine power must be chosen in accordance with the intended workpiece diameters.
	Choosing belts of different diameters.
	As the use of fasteners set of bolts and nuts of different diameters and lengths.
	Runners of steel rods made of steel rod, which is recommended to be tempered. You can also use ready-made elements of a suitable size b / a machine factory production (this also applies to the other units of the equipment).
	Spindle and "tailstock" are considered the most complex assemblies for the independent production, so you can refer to a specialized workshop or to the manufacturer. If it is decided to do everything on their own these items, the grandmother can be made of metal of appropriate thickness and shaped tubes. Simple spindle made of bolts ostrozatochennym end nuts and wheel.
	The feed can carve on the machine in a specialized workshop longitudinal and transverse screws or make your own rods with pre-threaded.
	To create rotating parts fit bearings, mounted on the body.
	The support can be made from steel plate with a thickness of 8 mm.
	The toolholder is prefabricated from a thick steel plate, to be ordered in a specialized workshop or taken from another machine.

Once the drawing is selected and prepared all the necessary materials and components, you are ready to assemble the unit.

Choosing an electric motor for a homemade lathe

The electric motor - the most important element of Metal lathes, whether industrial or home-made. It is responsible for operation of the equipment. The power of the electric motor depends largely on the functionality of the lathe. If the machine is intended for use with workpieces of a small size, the motor will be sufficient to 1 kW (can, for example, take the old garment or washing machine). For large parts need a power unit with capacity within 1.5-2 kW.

The order of assembly of the lathe for metal

To lathe work properly, it is important to build it, and for this you just need to follow the following algorithm:

1. Formation of the frame. Since the creation of the iron bed in the home is almost impossible, you have to use steel pipes, which are cut to size and welded together. Always ensure that all angles were equal, and focus on the drawing.
2. Creating side racks.
3. Racks connect rails, and side supports install special bushings.
4. Installed on the guide sleeve, on which the tailstock is mounted, and they are used for reliable fastening of the tool holder.
5. Creating platforms of steel sheet thickness necessary for installation of a support and quill.
6. Installation of the screw shaft.
7. To the lead screw is attached and vernier steering wheel.
8. Fastening site for installation headstock.
9. Collecting headstock and tailstock, after which they are installed on the machine.
10. Create a support and tool holder.
11. Collection of the subframe for the electric motor. For this purpose, steel pipes or area. Subframe will perform lifting and lowering motor.
12. Assembling the power unit, followed by connecting it to the mains.
13. A trial run of the lathe.
14. If everything is functioning normally, you can paint the machine (if desired), and get to work on it.

If desired, conventional turning equipment can be re-equipped with their own hands in the milling machine for metal.

Doing their own hands lathe of drills

Make a lathe and can be of an electric drill, but in general, this design is suitable for the treatment of wood. Of course, it can be used for working with metal, but used the power unit should be as powerful but very small parts. For example, such stanochek suitable for homebrew amateur jeweler. This design consists of a minimum of parts. So, go to the step by step instructions for making a lathe from a drill with a photo and description.

Illustration	Description of the action
	On board using pads, a collar and screws Drill set, as shown in the photo.
	The cartridge traps the sharpened screw with the "lamb."
	Hold the line on the board, which coincides with the chuck center is marked at several uniform sections and make small holes with a diameter smaller than that of self-tapping screws.
	Install a tailstock (G-shaped design of the colon plywood) And baits it with screws and washers.
	The drill chuck stifle wood Æ 10 mm.
	With the help of a drill to make the tailstock center (it helps that the screws are not tightened up to the stop).
	The resulting insert hole D-shaped screw and drill stifle by its nut.
	Reliably traps the nut with a wrench, holding screw for the "tail".
	Hold the preform. As podruchnik use a piece of thick plywood with bolted thereto a metallic area with a height corresponding to one of the sides. So our process has begun!
	Mark up the blank, and you can begin to vytachivaniyu figures or something else.

Several ways to modernize a homemade lathe

Sometimes it is necessary not only to carve detail of the machine, but also to polish and paint it evenly. You can use multiple devices or just spend some improvement homemade lathe equipment. The easiest way to do this with the structure made by electric drills.

Consider a few modifications for different types of work:

1. Belts from the pulleys must be covered with a protective cover (for security reasons).
2. Inclusion in the electric circuit of the machine, emergency braking button, which should be in the area close availability.
3. It is recommended to install a protective cover from a transparent polymer in the working zone.
4. Recommended that the electric circuit equipment RCD, Temperature sensors and other safety devices.
5. Conventional light bulbs to illuminate the work area should be replaced at the cost LED lighting fixture with high resistance to vibration.
6. The machine is recommended on the depreciation of the spring to reduce vibration and noise.
7. For working with workpieces of different lengths can be made collapsible base.
8. Attaching to the cartridge sanding or grinding wheel, it is possible to polish the various parts, and perform sharpening scissors, knives and other instruments.

Features homemade lathes

Homemade lathes, as well as other equipment, have their own characteristics. For example, it is not recommended to install the equipment on the collector motor, as is often spontaneous increase in the number of revolutions, which in turn can lead to the release of the details of the cartridge and, accordingly, industrial injury. In the event that no other way, then you need to install an optional reducer, reducing turnover. It is best to use an asynchronous motor, because it is more resistant to various stresses and does not increase the number of revolutions.

Despite the fact that the self-made lathes do not have the high performance, they are energy efficient. This cost-effective, given that such equipment carried small amount of work. In addition, they are small in size and low noise level, so you can use the mini-machines at home. Equipment just to maintain and operate, besides, it is relatively inexpensive.

Household lathes can replace the standard industrial equipment in many respects. They can also carry out surface and the end processing of the details to make the external and internal threading, drilling, countersink, bore logging and much more. Just as with the professional equipment, improvised handling machine tool operate workpieces corresponding metal stamp.

Basic safety precautions when working on a lathe

Designing the machine and working on it, you need to observe basic safety rules. The first test should be carried out tests of the equipment. All moving and rotating parts must have free play, without any delay. spindle and tailstock centers must match exactly.

The electric motor and the working area need to be equipped with a protective cover and a reliable transparent screen. Work tool must be positioned strictly parallel relative to the workpiece and securely fastened. When processing the ends of details she should have a good emphasis in the tailstock and correct ottsentrovku.

All electrical contacts should be well insulated, and the equipment itself grounded. After the work is finished, the equipment must be cleaned to remove chips from metal, wood or other materials. If there is no transparent protective screen must always be used for special glasses.

Care lathe

On the condition of the equipment, directly depends on his work. The lathe must be regularly inspected, cleaned, at the slightest failure to immediately remove it. Before working gently to check the overall condition of the equipment, the engine, move the moving and rotating elements, and lubricate if necessary.

In the process, you can not put on the rails of the machine any instruments, Billet, measuring tools etc. In no case can not knock on the handle of the tool holder. From time to time it is necessary to disassemble the cutter holder, cleaned from dirt and process with special grease or lubricating oil.

After work the machine must be carefully removed to on the rails, supports and other parts remained moisture, chips or dirt.
