Determining the process requirements of typical parts, the batch size of workpieces to be processed by CNC lathes, and formulating the functions that CNC lathes should have are the prerequisite conditions for making good preparations and rationally selecting CNC lathes: meeting the process requirements of typical parts.
The main process requirements for typical parts are the structural dimensions, processing range and precision requirements of the parts. The control accuracy of the CNC lathe should be selected based on the precision requirements, that is, the dimensional accuracy, positioning accuracy and surface roughness requirements of the workpiece. The selection should also be based on reliability. Reliability is the guarantee for improving product quality and production efficiency. The reliability of a CNC machine tool refers to its stable operation for a long time without failure when performing its functions under specified conditions. That is, the mean time between failures is long. Even if a failure occurs, it can be restored in a short time and put back into use. Choose machine tools with a reasonable structure, excellent manufacturing quality and those that have been mass-produced. Generally, the more users there are, the higher the reliability of the numerical control system will be.

Machine tool accessories and cutting tools

The random accessories, spare parts and their supply capacity of machine tools, as well as cutting tools, are of great significance to the CNC lathes and turning centers that have been put into production. When choosing a machine tool, it is necessary to carefully consider the compatibility of the cutting tools and accessories.

Control system

Manufacturers usually choose products from the same manufacturer. At the very least, they should purchase control systems from the same manufacturer, which brings great convenience to maintenance work. For educational institutions, as they need students to be well-informed, it is a wise choice to select different systems and equip them with various simulation software.
​
Choose based on the performance-to-price ratio

Make sure that the functions and precision are not idle or wasted. Do not choose functions that are irrelevant to your needs.

Protection of machine tools

When necessary, machine tools can be equipped with fully enclosed or semi-enclosed protective devices and automatic chip removal devices. When choosing CNC lathes and turning centers, all the above principles should be comprehensively considered.
