Preliminary Preparations: Determining the process requirements of typical parts, the batch size of workpieces to be processed, and outlining the functions that the CNC lathe should possess are prerequisites for proper preliminary preparation and rational selection of a CNC lathe: meeting the process requirements of typical parts.
The process requirements of typical parts mainly include the structural dimensions, machining range, and accuracy requirements of the parts. Based on the accuracy requirements, namely the dimensional accuracy, positioning accuracy, and surface roughness requirements of the workpiece, the control accuracy of the CNC lathe is selected. Reliability is also a crucial factor, as it guarantees improved product quality and production efficiency. The reliability of a CNC machine tool refers to its ability to operate stably for extended periods without failure under specified conditions. This means a long mean time between failures (MTBF) and the ability to recover and return to use quickly even after a failure. Select machine tools with a reasonable structure, excellent manufacturing, and already in mass production. Generally, the more users, the higher the reliability of the CNC system.
Machine Tool Accessories and Cutting Tools: Machine tool accessories, spare parts, and their supply capacity, as well as cutting tools, are extremely important for CNC lathes and turning centers already in production. When selecting a machine tool, the compatibility of cutting tools and accessories must be carefully considered.
Control System: Manufacturers generally choose products from the same vendor, or at least control systems from the same vendor, which greatly facilitates maintenance. For educational institutions, where students need to have broad knowledge, selecting different systems and equipping them with various simulation software is a wise choice.
Price-Performance Ratio Selection: Ensure that functions and precision are not idle or wasted; avoid selecting functions irrelevant to your needs.
Machine Tool Protection: When necessary, machine tools can be equipped with fully or semi-enclosed protective devices and automatic chip removal systems.
When selecting CNC lathes and turning centers, all the above principles should be considered comprehensively.
