lathe is one of the first machine tool that was made mostlyfor processing of any material - wood, plastic and metal.With this machine, you can get the details of the various form in the processing of the outer surface, and drill the bore holes, threading and knurled knurled surface.
Manufacturers now made a large number of different lathes.However, they are often too complicated for homework, cumbersome and costly.Excellent alternative to this - making small homemade lathe for wood or metal, which is easy to use thanks to its small size and ease of management, and allow
good to have in a house using wood lathe, with which you can carve small parts for furniture, handles for handtools, derzhak for household equipment.Starting with simple products, you can gradually reach the Grace of turned furniture sets and parts for sailing yachts.With lathes can carve the necessary details of circular cross section: axle or wheel.
works on a similar principle lathe is simple enough: the workpiece is clamped in a horizontal position, attached to the rotary motion and the excess material is removed movable cutter.However, to implement this simple manipulation mechanism is required, which consists of many parts, like fitting together.
Lathes have come a long way of development, being once primitive devices and has now turned into high-performance equipment for turning.A couple of thousand years to the present day the most simple device for processing of wood and stone and give them a fitting cylindrical surface and used in ancient Egypt.
In the early eighteenth century, our compatriot, inventor and engineer Andrew Nartov designed and created the first lathe with caliper with mechanical movement.It was the beginning of the production of modern lathes with their hands and enterprises.Many details in Nartova machines, pulleys, rails, gears, screws, are metallic.Machine tools, as before, leads a person to move the handwheel.
At the end of the eighteenth century after the invention of the steam engine and the internal combustion engine, and then the electric motor manual transmission replaced by machines.Transfer to the lathes of the total traffic carried out by the engine transmission shaft.It hung from the ceiling or wall shop.The movement of the shaft is transmitted to the machine via a belt transmission.
lathes in the early twentieth century began to equip efficient electric motors for each individual machine.Simultaneously, machines began to improve, as they lacked the mass production.Industry machines were needed for high performance and the highest quality machining.
To change the number of revolutions of the spindle, and improve the mechanism of machines, they began to be equipped step-pulley drive.The lead screw spindle connected by a guitar from the gears.These units were subsequently supplemented by Gearbox.Another innovation that appeared in lathes, became separate from the transfer of motion of the screw shaft and the roller on the caliper.In the first case occurred threading, the second-all other operations.Modernization also touched mechanism apron.
rapid development of lathes has accelerated the emergence of high-speed steel.Its use has allowed to increase the cutting speed up to five times when compared with the speed of processing of ordinary carbon steel.To increase the number of turns, the number of different types of innings, lathes were equipped with even more sophisticated transmission and rotation, as previously used bearings replace the bearing rotation.Particular attention has been paid to self-lubricating parts of the lathe.
simplest homemade lathe that is intended for the treatment of wooden pieces in its design has several main components: the frame, the front and back of the headstock, the master and slave centers, electric drive, stop for the cutter.The frame serves bed and support for other units of the machine.Headstock is fixed and serves as a base for the location of the main assembly of the rotation.
The front frame is placed transmission mechanism that connects an electric motor and a leading center.The rotary movement is transmitted through the leading center piece.Along the frame moves freely tailstock.Her move regardless of the length of the workpiece in such a way as to secure the workpiece firmly driven through the center.
for lathes can use any drive, but only according to its capacity in terms of turnover and the workpiece.And if a decrease of revolutions and the fall can be solved with the help of the transfer system, the engine power will remain unchanged.
Theoretically homemade desktop lathe can approach any motor, even at 200 watts, but if you are going to handle the massive blank, it may be overheating and cause frequent stops.Most often used for transmitting rotation belt drive, friction and sometimes even chain.Perhaps the solution to the lack of gears, where the cartridge or drive is mounted on the center shaft of the electric motor.
masters and centers should be placed on the same axis, or harvesting will vibrate.This must be performed by the following conditions: fixing, alignment and rotation.The frontal machine applies only leading center.Fixing the workpiece in this case takes place by means of the cam holder or chuck.
Rama decided to collect from metal profiles, or corners, and may consist of a piece of wood.In any case, it should be provided rigid fixation master and slave centers.The frame design so that when setting up the tailstock can move freely along the axis.The focus for the cutter must also move.
After installing the necessary provisions should be established rigid fixation of all the elements homemade mini lathe.From the purpose of work, type and size of workpieces determines the final size and shape of the aggregate structure.Depending on the purpose of the machine is also chosen a variety of electric power and that transmits a rotating force of the details right.It must have characteristics which correspond to the test load.
commutator motor for stable operation of the electric fit the least.With no load RPM uncontrollably increase, and under the influence of centrifugal force extreme preform can fly from locks, which is very dangerous.Perhaps the use of such motors with gear, which limit the uncontrolled acceleration of the workpiece.But in the process of vytachivaniya miniature parts with low weight to worry about.
for processing a workpiece, which has a diameter of 10 centimeters and a width of 70 is recommendable to use an asynchronous motor with a power greater than 250 watts.This kind of electric resistance has a speed under load, and they have no extreme increase in speed at no load and high rotating mass of the workpiece.
On the other hand without using the belt drive, and in the application of the motor shaft as a center portion of the lead within the motor bearings undergo strain to which they were not designed.Shaft bearings are designed exclusively to the load that is applied at right angles, but made their own hands miniature lathes turns out that there is also a force that is directed along the shaft and provokes the rapid destruction of the motor bearings.
So you can compensate for the longitudinal force.Must be made from the back side of the shaft blank, where there are technological recess.Depending on the design features of the engine to be found in the back of the support, to make a similar groove and put the ball the necessary size between it and the end of the shaft.Emphasis should be well pressed against the ball to the shaft, otherwise the sense of such a bearing will not.
Slave center is rotating or stationary.It is located on the tailstock of the machine.If the center is fixed, it is made of an ordinary bolt, imprisoning the end of the threaded portion of a cone.The grandmother also has an internal thread.Then, when the rotation of the bolt can be pointed to press the workpiece between the centers.
stroke bolt is 20-30 millimeters, put the rest away for guiding the movement of the axis of the tailstock.Polished pointed bolt that serves driven center before work lubricate the engine oil to avoid fuming blank, as shown in the video of lathes.
own hands lathe can collect each craftsman.It is characterized by ease of manufacture and reliability.On it, you can make and eat through the details, as well as to sharpen the cutting tool and the grinding of metal products, works with bone, plastic and wood, creating wooden souvenirs and household items, as well as the repair of the car.
While at home, you will have to do with his hands arched type lathe.It is multifunctional and easy to use.And the ease of substitution of steel components ensures long service life of the equipment and its ability to switch to work with different materials.The two wooden racks that pre-sawn, attach the bolts and tighten the nuts.
These racks can strengthen the structure and prevent loosening of the wooden racks.Make sure the holes for the screws chosen approach and to thread nuts are appropriate.That in the course of work are not staggered cutter and chisel, they decided to strengthen podruchnik which represents two plates that are interconnected by means of adhesive or screw means at a right angle.
Compulsory lower plate should be bevelled corner and strip of iron, prevents deformation of chisels in motion.The horizontal plank in turn equipped with a slot to control movement podruchnik and management for the most high-quality work.To podruchnik was able to rotate freely at the base of the workpiece do along the surface of the punch holes for screwing.
the wood to be processed, tightly screw the nuts, detail through this tightly secured and moves freely.Now, with his own hands made mini lathe is ready for use, but does not think that the details should be processed only in one direction.Homemade lathe allows to rotate parts in different directions to achieve optimal form of the object and the possibility of future decoration.
to manufacture lathe with their hands, you can take a low-power motor (250-500 watts) that is available, or buy a previously used engine at an inexpensive price.A good option is to use a motor of a sewing machine.Just look photos of homemade lathes to see this!Back and headstock can be made independently.
grinding and abrasive wheels must be mounted on the exposed end of the shaft of the engine.With their help, a homemade lathe can perform, in addition to sharpening tools, grinding or polishing surfaces.Thus, the lathe at home - it is simply irreplaceable thing in the diverse processing of metal and wood.
If you set the grinding wheel instead of a special adapter with keyless chuck, then this machine will be used for Drill holes and milling slots in the product.By the way, in addition to wooden battens, for the manufacture of the frame can use a set of profiled metal - angles, channels, beams and the sheet material.Under a small lathe, you can adjust or conventional electric sander.
Now you have learned about the purpose and use of lathes in the household.No wonder that this equipment has a long way!Self can be made simple miniature lathe which nevertheless successfully cope with their tasks, whether, grinding or undercut parts required size of wood or metal.
