The small series of Weifang numerical control steel bar cage roll welding machine tells you the choice principle of numerical control
1 preliminary preparation
Determine the process requirements of typical parts, batch processing of the workpiece, draws up the function of NC lathe is good preparation, the reasonable selection of the precondition of CNC lathe, meet the requirements of a typical part of the process and the technological requirements of typical parts is mainly parts of the structure size, processing range and accuracy requirements. According to the precision requirement, that is, the size precision of the workpiece, the positioning accuracy and the surface roughness of the requirements to selec the control accuracy of the CNC lathe. Reliability is the guarantee of improving product quality and production efficiency. The reliability of CNC machine tools is to refer to the machine in the specified conditions of the implementation of its functions, a long time stable operation without failure. That is, the average time without failure, even if the failure, short time to recover, re put into use. Choose a reasonable structure, sophisticated manufacturing, and has been mass production of machine tools. In general, the more users, the higher the reliability of the numerical control system.
2 purchase
Machine tool random accessories, spare parts and their supply capacity, cutting tool, has been put into operation of CNC lathes, turning centers is very
3 pay attention to the identity of the control system
Manufacturers generally choose the same manufacturers products, at least to buy the same manufacturers control system, which brings great convenience to the maintenance work. The teaching unit, due to the need of students informed, choose a different system, equipped with a variety of simulation software is a wise choice.
4 according to the performance price ratio to choose
Do function, accuracy is not idle, do not waste, do not choose and do not need to be independent of the function.
5 Protection of machine tools
When needed, the machine tool can be equipped with fully enclosed or semi enclosed protection device, automatic chip removal device.
In the choice of CNC lathes, turning centers, should consider the above principles.
