Turning lathe on metal – the irreplaceable tool in arsenal of the house master. With its help it is possible to turn various parts which in a different way to make rather difficult. Not to everyone on pocket to buy the shop-assembled machine. But those who own skills of metalwork works can quite try to make small turning lathe by own efforts.
It is required to you
- - sheet metal plate;
- - channel;
- - steel strips;
- - steel corners;
- - engine;
- - transmission gear;
- - fastening elements (bolts, nuts);
- - set of metalwork tools;
- - wrenches;
- - angular grinder ("Bulgarian");
- - welding machine.
Instruction
1. Pick up the engine for turning lathe. Optimum, if it has power about 2 kW and to develop up to 2000 revolutions per minute. But the engine with lower performance data, for example, from the washing machine which has served the term or from electric drill quite will be suitable for the machine of small power also. Consider that more powerful engine will allow to process more massive preparations.
2. Use for the machine the gearbox from the midget car, having removed with "Bulgarian" coupling basket. This device will provide several operating modes of the machine differing in speed. It is possible to increase turns if to equip installation with additional pulley.
3. From steel corner or P-shaped channel weld frame for the bed. Wedge the bed the extended couplers, having made distance between edges identical. Collect guides from elements of square section and steel strips. From pieces of sheet metal plate weld also box of cam cartridge, and then install in it bearings with possibility of adjustment.
4. Weld back block from steel corner and thick plate which will lean on guides. The block has to have opportunity without efforts to move on guides. Weld nuts for fixing of the back supporting center on the top plane of back block.
5. Build in the front center in the form of the ground cone in spindle, having tried to make it as it is possible more precisely. Inaccuracies in installation can lead to strong radial beating during processing of massive parts. In the simplest case the front center can be turned from the bolt suitable by the size.
6. Aggregate all design of the machine. Check, the spindle how freely rotates. Adjust the front and back centers so that they were on one axis. Surely provide the protection cover for the transmission gear – it will ensure safety of the operator of the machine.
