Selection principles for CNC

• preparation in advance

    The determination of the process requirements for typical parts and the batch size of processed workpieces, as well as the formulation of the functions that CNC lathes should have, is a prerequisite for preparing in the early stage and selecting CNC lathes reasonably: meeting the process requirements of typical parts.

    The process requirements for typical parts mainly include the structural dimensions, processing range, and   accuracy requirements of the parts. Select the control accuracy of a CNC lathe based on accuracy requirements, including the dimensional accuracy, positioning accuracy, and surface roughness of the workpiece. Choosing based on reliability is a guarantee for improving product quality and production efficiency. The reliability of CNC machine tools refers to the stable operation of the machine tool for a long time without malfunction when performing its functions under specified conditions. The average time between failures is long, and even if a malfunction occurs, it can be recovered in a short period of time and put back into use. Choose a machine tool with a reasonable structure, excellent manufacturing, and mass production. Generally, the more users there are, the higher the reliability of the CNC system.

• Machine tool accessories and tools

    machine tool accessories, spare parts and their supply capacity, and tools are very important for CNC lathes and turning centers that have been put into operation. When choosing a machine tool, careful consideration should be given to the compatibility of the cutting tools and accessories.

• Control system

   Manufacturers generally choose products from the same manufacturer, and should at least purchase control systems from the same manufacturer, which brings great convenience to maintenance work. Teaching units, due to the need for students to have a wide range of knowledge, choosing different systems and equipping them with various simulation software is a wise choice.

1.Choose based on performance price ratio

   Ensure that functions and accuracy are not idle or wasted, and do not choose functions that are unrelated to your own needs.

2.Protection of machine tools

       When needed, the machine tool can be equipped with fully enclosed or semi enclosed protective devices and automatic chip removal devices.

  When selecting CNC lathes and turning centers, the above principles should be comprehensively considered.
