Homemade lathe for metal with their hands

The lathe is needed for the manufacture and processing of metal parts. Professional equipment is quite expensive, so in order to save, you can make a homemade lathe for metal hands. This can be done in several ways, and the drawings of this product are easily found on the Internet. Can be used to make available materials, the size of the machine may be any.

The components of a mini-lathe for metal with their hands

Any homemade lathe consists of the following elements:

• Drive - the main part of the mechanism that is responsible for its performance. Selects the drive power required is one of the most difficult tasks. Small Metal lathes with your hands, you can use the drive from a conventional washing machine or a drill. Usually, the power of this element begins at 200 W, and the number of revolutions per minute - 1,500;
• frame - bearing frame construction which can be made of wooden beams or steel angle. The bed must have a high strength, or the entire structure may collapse from vibration during operation;

• tailstock - made of steel plates and weld steel angle thereto. The plate rests on the guide frame, and the main purpose of the tailstock of the lathe with their hands is the fixation of the metal parts treated;
• headstock - part similar tailstock but is installed on the movable frame;
• master and slave centers;
• Caliper - thrust mechanism for the working part.

The torque from the engine to the working parts of the machine may be transmitted in several ways. Some people prefer to directly set the working part of the motor shaft - this saves space and allows you to save on spare parts. If this is not possible, the torque can be transmitted by means of friction, belt or chain transmission. Each of these options has advantages and disadvantages.

Belt drive for the electric motor is the cheapest and is characterized by a relatively high level of reliability. For its production can be used for the belt motor, taken from any other mechanism. The lack of a belt drive is that over time, the belt can be washed and should be changed more often than the more intensively you are working with the machine.

The chain drive is more expensive and takes up more space, but also to serve much longer than the belt. Friction transmission has intermediate characteristics between the belt and the chain.

Useful advice! When assembling the lathe choose the type of transfer that will best fit the task. For example, a mini-lathe with his hands more suitable setting of the working part directly on the shaft.

Caliper lathe with his own hands: drawings, how to make from scrap materials

Caliper is one of the most important parts of improvised lathe - the quality of the future detail depends on it, as well as the amount of time and effort you spend on its production. This part is located on special skids, which are moved along the guide rails located on the frame. The support can move in three directions:

• longitudinal - working part of the machine moves along the workpiece. Longitudinal movement is used to vytachivaniya thread in the workpiece or for removal of bed material from the surface of the metal workpiece;

• lateral - movement perpendicular to the workpiece axis. It used to vytachivaniya recesses and holes;
• inclined - movement at different angles to the recesses vytachivaniya on the workpiece surface.

In the manufacture of slide lathe with their hands should take into account the time that this part is subject to wear as a result of occurring vibrations during operation. Because of them, fixing loosened, there is free play, all this affects the quality of the manufactured parts. To avoid such problems, you need to regularly adjust the caliper and adjust.

Adjusting homemade slide lathe with his own hands made of gaps, backlash and packings. Clearance adjustment is needed in the case when the screw is worn in charge of moving parts in the longitudinal and transverse planes. As a result, caliper friction begins to fall apart under load, which significantly reduces the accuracy of the workpiece. Repair gaps can be by inserting wedges between the guides and the carriage. Backlash is eliminated by means of parts of the fixing screw.

If your machine is worn seals, they should be rinsed thoroughly and soak fresh engine oil. In the case of the critical wear of the seal should be replaced entirely by new ones.

Homemade lathe for metal with their hands: build order

the mechanism assembly is performed in the following order:

1. Of metal beams and channels going to the machine frame. If you want to work with large items, and materials for the frame assembly to be used with the expectation of a greater load. For example, if you plan to work with metal preforms over 50 mm, the thickness of materials for the frame should start from 3 mm to corners and 30 mm - for the rods.
2. On channels set longitudinal shafts with the guides. Shafts can be welded by welding or bolted.
3. Made headstock. For the manufacture of the headstock of a lathe with his hands using a hydraulic cylinder with a wall thickness of 6 mm. The cylinder is necessary to drive in two bearings.
4. Laid shaft. For this purpose, bearings with a larger inner diameter.
5. The hydraulic cylinder is filled with a lubricating fluid.
6. Mounted pulley and slide the guide.
7. Mounted actuator.

In addition, according to the drawings of a lathe for metal with their hands it is clear that to improve the stability incisal mechanism podruchnik manufactured, and a thin strip fixed to the bottom of the structure metal. The latter serves to protect the operating parts of the machine from deformation in the process.

Useful advice! Lathe for metal, collected his own hands, can be used not only for its intended purpose, but also for the grinding and polishing of metal parts. To do this, the electrical shaft joins the grinding wheel.

Motor selection for the machine

The most important part of a home-made lathe on the metal, which is the manufacture of video can be easily found on the Internet, it is an electric motor. It is carried out with the help of the movement of the working parts of the machine. Accordingly, the power of this mechanism depends on the power of the whole structure. It is selected depending on the size of metal blanks with which you plan to work.

If you plan to work on the machine with small details, this is quite suitable for the motor with power up to 1 kW. It can be removed with an old sewing machine or any similar appliance. To work with large spare parts you need to drive with a capacity of 1.5-2 kW.

When the assembly of finished drawings homemade lathe for metal, keep in mind that all the electrical parts of the structure must be separated. If you do not have the necessary experience working with electrical equipment, it is better to ask for help on connecting to a specialist. So you will be assured of job security and reliability of the design.

Making a lathe of drills with their hands

If you want to save on spare parts and greatly simplify your task of assembling a homemade lathe, as a drive, you can use an ordinary electric drill. Such a constructive solution has several advantages:

1. Possibility of quick assembly and disassembly of the structure - the drill is easily detached from the frame and can be used for its intended purpose.
2. Ease of transport and transport of the machine - a good option if you have to work with the metal blank in the garage and on the street.
3. Savings - Drill acts not only as a motor but also eliminates the need for transmission, as well as allows the use of interchangeable tips as a working tool.

Of course, there are downsides at the lathe from the drill. How do the treatment with the help of this tool, large parts as possible? This is not practicable, because the drill relatively low torque and high speed. Of course, you can increase these parameters, if you still install the belt drive and use it to transmit torque from the Drill down on the spindle, but it greatly complicates the design, the main advantage of which is the simplicity and compactness.

Making a homemade bench lathe for metal-based drill makes sense in the when you do not need to conduct large-scale works, and only need to grind fine details.

To manufacture a lathe for metal-based electric drill you will need the same parts as for the conventional construction with the exception of the motor and headstock. The role of the latter also serves as a drill. In view of compact design, as the frame may be used a conventional table or bench on which are fixed all the components of the machine. Drill itself is fixed in construction with the clamp and clamp.

Useful advice! The functionality of a lathe based on an electric drill can be greatly extended if we add to its design various nozzles and attachments.

With homemade lathe can not only grind the items, but also applied to a rotating workpiece paint, to wind wire on a transformer to do on the surface of the spiral incisions and perform many other actions. In addition, if you collect for the machine-copier-top box, then you can use it to quickly and easily produce small identical parts.

Features of Metal lathes with their hands, video instruction as a way to avoid mistakes

Like any other equipment, from homemade lathe has its own characteristics that must be considered during assembly and operation. For example, when working with large parts, or by using a powerful electric motor there are strong vibrations, which can lead to serious errors in the machining of the workpiece. To get rid of the vibration, the driving and driven machine centers to be installed on the same axis. And if you plan to install only the leading center, it must be attached to the cam mechanism.

In Table lathes with their hands on metal is not recommended to install the engine manifold. He is prone to spontaneous increase in the number of turns, which could lead to the departure details. This, in turn, can lead to personal injury or property damage. If the engine without having to install the collector can not do, complete with it necessarily must be installed to reduce the speed reducer.

The ideal goal for homemade engine lathe is asynchronous. It does not increase the frequency of revolutions during operation, is resistant to greater loads and allows working with metal workpieces with a width of 100 mm.

Rules of installation and operation of any type of motor lathe can be seen in many video instructions on the Internet. With their help, you will not only avoid the common mistakes during assembly, but also save time and effort because of the visibility of the material.

Safety precautions when working with a homemade lathe

When working with the design should comply with certain security measures. Thus, after the assembly of the machine is necessary to verify its performance. The spindle must rotate easily and without delay, the front and rear center must be aligned on a common axis. The center of symmetry of the rotating parts should coincide with the axis of rotation.

On any video lathe their own hands can be seen that after the installation of the motor it is covered by a special casing. The latter serves not only to protect the machine operator, but also for the protection of the motor from dust, metal particles and dirt. Machine-made on the basis of an electric drill, a cover is not needed.

Useful advice!If you plan to design the installation on the basis of a powerful electric motor, be sure to make sure that working with him enough power to your mains supply. At home, the better to avoid the motor from household appliances, which is exactly the work on the voltage in your wall socket.

You should also adhere to the following safety rules:

1. Working tool must be positioned parallel to the surface of the workpiece. Otherwise, he may come off, resulting in damage to the machine.
2. If you treat the end plane part must rest on the tailstock. It is very important to observe the alignment, otherwise you run the risk of defective part.
3. To protect your eyes from metal shavings and particles can build a special panel or simply use goggles.
4. After work, the design necessarily need to be cleaned by removing metal shavings and other waste products. Keep an eye on the fact that small parts do not fall into the motor.

Upgrade options homemade lathe

If you need a mechanism that will not only perform turning, but also sanding and painting preparation, basic machine can be easily modified. The best thing to do is to design on the basis of an electric drill as part of the work to replace it the easiest way.

There are several popular modifications of Metal lathes. How to make a cone-shaped hole? To do this, you must attach to the base two of a file so that they form a trapezoid. Thereafter mounted a spring mechanism which feeds forward of files and at an angle that allows drilling into the details of tapered holes.

In addition, to work with the metal parts of different lengths can be made machine with a collapsible base. With a few boards or metal parts can zoom in or out to the working tool fastenings, holding parts, as well as change the size of the gap between the bindings. The most convenient way to do such a structure based on a conventional desk or workbench.

If attached to the motor as a grinding wheel of the tool, the machine can use the deal not only with polishing the surface of the part, but also sharpening knives, scissors, and other household tools. Thus, the lathe turns into a handy multi-function mechanism.

Assembling a lathe at home is an easy task, which further simplify the numerous video instructions and drawings from the Internet. In this case, the assembled structure can be literally out of scrap parts, using old appliances and waste installation and construction industry.

The main advantage of the self-assembly - a savings. In addition, it is worth noting the opportunity to self-regulate the size and power of the device to adjust it to your needs. homemade machine It may be not only large, but also very tiny, designed to handle small parts.
