The difference between manual lathes and CNC lathes

1. Different structure

The feed system of the manual lathe includes a feed box and a slide box. It is used for turning the surface of the workpiece by the lead screw and the smooth bar; the CNC lathe has a numerical control system, feed and hydraulic systems, etc., and the thread processing of the workpiece surface is carried out in the turning center. The latter is more conducive to production management.

2. Different machining methods

Manual lathes need to be manually operated to light the workpiece, and workers must manually shake the tools to process the parts in strict accordance with the lathe use regulations; CNC lathes directly process product parts in accordance with the prescribed instructions issued by technicians through data control.

3. Different machining precision

There are few types of parts that can be processed by manual lathes. Due to the lack of automation, the processing accuracy and quality of parts are not as good as those of CNC lathes; CNC lathes can process parts with complex shapes by changing the control program, and the stability and repeatability of the processing quality are higher.

4. Different applicable conditions

Because manual lathes are more flexible in manual operation, the equipment is subject to large forces, and it is not easy to process complex parts, and it is more convenient to process single products; CNC lathes with the same large equipment are less stressed, and each part is more precise, suitable for more complex processing. And the production of high-volume mechanical parts.

5. The cost of construction and maintenance is different

The cost of manual lathes is low, the investment is small, and debugging can be done manually before use. The maintenance of ordinary lathes is mainly due to the wear between components, and the maintenance cost is not high; the use cost of CNC lathes is high, and the investment is large, and multiple debugging must be carried out before use. , The preparatory work is complicated, and all systems including CNC programs are regularly maintained, and the maintenance cost is high.

6. Different installation requirements

Manual lathes must strictly control the ambient temperature, humidity, power supply voltage and other conditions; CNC lathes level the position on the basis of avoiding direct sunlight and humid airflow as much as possible, and the reading of the level meter does not exceed 0.04/1000mm.
