Characteristics and selection principles of CNC lathes (automated machine tools)?
CNC Lathe Machine Features:
CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, and decode it, so that the machine tool can operate and process parts.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
●High processing precision and stable processing quality;
●Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed;
●When machining parts change, generally only need to change the NC program, which can save production preparation time;
●The machine tool itself has high precision and high rigidity, can choose favorable processing dosage, and has high productivity (generally 3~5 times of ordinary machine tools);
●The machine tool has a high degree of automation, which can reduce labor intensity;
●Higher requirements for the quality of operators and higher technical requirements for maintenance personnel
CNC Metal Lathe Selection principle:
Determine the process requirements of typical parts and the batch of processed workpieces. The function that the CNC lathe should have is to make preparations and the prerequisite for the reasonable selection of CNC lathes: meet the process requirements of typical parts.
The process requirements of typical parts are mainly the structural size, processing range and accuracy requirements of the parts. According to the accuracy requirements, that is, the dimensional accuracy, positioning accuracy and surface roughness of the workpiece, the control accuracy of the CNC lathe is selected. Choose based on reliability. Reliability is the guarantee for improving product quality and production efficiency. The reliability of a CNC machine tool means that the machine tool runs stably for a long time without failure when it performs its functions under specified conditions. That is, the mean time between failures is long, even if there is a failure, it can be restored in a short time and put into use again. Choose machine tools with reasonable structure, excellent manufacturing, and mass production. Generally, the more users, the higher the reliability of the CNC system.
Machine tool accessories and tools
Machine tool accessories, spare parts and their supply capacity, cutting tools, are very important for CNC lathes and turning centers that have been put into production. When choosing a machine tool, carefully consider the compatibility of tools and accessories.
Manufacturers generally choose products from the same manufacturer, and at least purchase control systems from the same manufacturer, which brings great convenience to maintenance. Teaching units require students to be knowledgeable and knowledgeable, so it is a wise choice to choose different systems and to equip them with various simulation software.
Performance and price ratio to choose
Make sure that the functions and accuracy are not idle, not wasted, and do not choose functions that have nothing to do with your needs.
Protection of machine tools
When necessary, the machine tool can be equipped with fully enclosed or semi-enclosed protective devices and automatic chip removal devices.
When choosing CNC lathes and turning centers, the above principles should be considered comprehensively.
