Lathes can be divided into several types depending on the purpose and function:
1.The general lathe has a wide processing target,and the adjustment range of the spindle rotation speed and the feed amount is large,and the inner and outer surfaces,end faces and internal and external threads of the workpiece can be processed.This type of lathe is mainly manually operated by workers and has low production efficiency.It is suitable for single-piece,small-batch production and repair workshops.
2.The turret lathe and the rotary lathe have a turret or a return turret that can hold multiple tools.In the one-time clamping of the workpiece,the workers can use different knives to complete various processes in turn,which is suitable for batch production.
3,the automatic lathe can automatically complete the multi-step processing of small and medium-sized workpieces according to a certain procedure,can automatically load and unload,repeat processing a batch of the same workpiece,suitable for large batch,mass production.
4.Multi-tool semi-automatic lathes are available in single-axis,multi-axis,horizontal and vertical.The layout of the single-axis horizontal type is similar to that of a conventional lathe,but the two sets of tool holders are respectively mounted on the front,rear or up and down of the main shaft for machining the disc,ring and shaft workpieces,and the productivity is 3 to 5 times higher than that of the ordinary lathe.
5,the profiling lathe can follow the shape of the sample or sample,automatically complete the processing cycle of the workpiece,suitable for small batch and batch production of more complex workpieces,the productivity is 10 to 15 times higher than the ordinary lathe.There are multiple tool holders,multi-axis,chuck type,vertical type and so on.
6.The main axis of the vertical lathe is perpendicular to the horizontal plane,and the workpiece is clamped on a horizontal rotary table,and the tool holder moves on the horizontal or vertical column.It is suitable for processing large,heavy and difficult to install on ordinary lathes.It is generally divided into two categories:single column and double column.
