CNC centerless grinding machine is an automatic machine tool with high precision and high efficiency. It has a wide range of processing performance, with the processing of circular arc, linear cylinder, oblique cylinder and various thread functions. It has all kinds of compensation functions such as linear interpolation and circular interpolation, and has played a good economic role in the batch production of complex parts. However, the following points should be considered in choosing nc lathe reasonably. 1. The preliminary preparation determines the process requirements of typical parts and the batch of the workpieces. The function of the proposed nc lathe is to make the preliminary preparation, and the preconditions for the rational selection of nc lathe meet the technological requirements of typical parts.

The technical requirements of typical parts are mainly the structural dimensions, machining range and precision requirements of parts. The control precision of nc lathe is selected according to the requirement of precision, i. e. the dimension precision, positioning precision and surface roughness of workpiece. According to the choice of reliability, reliability is the guarantee to improve product quality and production efficiency. The reliability of nc machine tools refers to the stable operation of machine tools for a long time without failure when they perform their functions under specified conditions. That is, the average time of no failure is long, even if there is a failure, it can be recovered within a short time and put back into use. Choose machine tool with reasonable structure, excellent manufacture and mass production.

The more the general users, the higher the reliability of the nc system. The product of the same manufacturer that buys the same system pays attention to the identity of control system, manufacturer should choose the product of same manufacturer commonly, should choose and buy the control system of same manufacturer at least, this brings great convenience to the personnel of production operation and maintenance work. 3. Selecting machine tool equipment according to the performance and price ratio is to achieve the function and precision of the equipment without idling or wasting. Do not choose functions unrelated to your own needs, and do not choose machine tools that you need but do not have such functions. Iv. Tool accessories and tool selection tools, spare parts and their supply capacity, random accessories of machine tools, etc., are very important for CNC lathes and turning centers that have been put into production. In order to make the machine tool more durable, we can add some protective equipment to the machine tool. Can be equipped with some fully closed or semi-closed protective devices or automatic chip removal devices.

The above principles should be taken into account comprehensively when selecting CNC lathes and turning centers. There should also be more professional advice and some information on the Internet to judge.
