1, ordinary lathe. molding process
Wide processing target, large adjustment range of spindle speed and feed amount, can process the inner and outer surfaces of the workpiece, the end face and internal and external threads. This type of lathe is mainly operated manually by the workers and has low production efficiency. It is suitable for single parts, small batch production and repair workshops.
2, turret lathes and rotary lathes
The turret or tool holder that can hold a plurality of tools can be used by a worker to complete a variety of processes in succession using different tools in one clamping of the workpiece, and is suitable for batch production.
3, automatic lathe
According to certain procedures, it can automatically complete the multi-step processing of small and medium-sized workpieces, can automatically load and unload, and repeat the processing of a batch of the same workpieces, which is suitable for mass production and mass production. molding process

4, multi-tool semi-automatic lathe
There are single-axis, multi-axis, horizontal and vertical points. The single-axis horizontal layout is similar to that of ordinary lathes, but the two sets of tool holders are mounted on the front and rear or upper and lower sides of the spindle, and are used to process discs, rings, and shafts. The production efficiency is improved by 3 to 5 times than that of ordinary lathes. molding process
5, copying lathe
Can imitate the shape size of model or sample, finish the processing cycle of the workpiece automatically, apply to the small batch and batch production of the workpiece with more complicated shape, the productivity is 10-15 times higher than the ordinary lathe. There are multiple tool holders, multi-axis, chuck, vertical and other types.
6, vertical lathe
The spindle is perpendicular to the horizontal plane, the workpiece is clamped on a horizontal rotary table, and the tool holder is moved on the crosshead or column. Suitable for machining larger, heavier, difficult to install on the general lathe, generally divided into two categories: single column and double column.
7, shovel tooth lathe
At the same time as the turning, the tool holder performs a radial reciprocating motion periodically, and is used for forming tooth surfaces of the fork-lift milling cutters, hobs, and the like. Usually with a grinding attachment, a small grinding wheel driven by a separate motor grinds the tooth surface. molding process
8, special lathe
Lathes for machining certain types of workpieces on specific surfaces, such as crankshaft lathes, camshaft lathes, wheel lathes, axle lathes, roll lathes, and steel lathes.
9. Combined lathe
It is used for turning machining, but after adding some special parts and accessories, it can also carry out boring, milling, drilling, inserting, grinding and other processing. It has the feature of “one machine with multiple functions” and is applicable to engineering vehicles, ships or mobile repair stations. Repairman。 molding process
