Basic knowledge of precision parts processing

　　First, the repetitive production of parts using numerical control grinder process preparation time occupies a high proportion. For example, process analysis preparation, programming, part first adjustment and trial cutting, etc., the sum of these comprehensive working hours is often dozens to hundreds of times the processing time of a single part, but these numerical control lathe work content can be saved and used repeatedly, so when a part is successfully trial-produced on the numerical control grinder and then put into production again, the production cycle is greatly reduced, the cost is also less, and better economic benefits can be obtained.

　　The numerical control grinder for medium and small batches of key parts that requires focus on ensuring processing quality and efficient production can realize high-precision, high-quality and high-efficiency grinding processing under computer control. It can save a lot of special process equipment compared with special grinder processing, has strong flexible manufacturing ability and obtains better economic benefits. Compared with ordinary grinders, it can eliminate many artificial interference factors in the long process of complex processing, and the precision and interchangeability of processed parts are good, and the processing efficiency is high.

　　As a single CNC grinder, it is difficult to complete the entire processing content of a part. The numerical control lathe processing needs to be transferred and matched with the processing procedures of other equipment, so there are requirements for production rhythm and workshop capacity balance. Therefore, it is necessary to consider giving full play to the processing characteristics of numerical control lathes, and numerical control lathes should reasonably arrange supporting balance processes on other processing equipment.

In addition to basic knowledge, how should we control accuracy?

　　Fourth, some special precision parts processing considerations Although some parts are processed in small batches, ordinary lathes are complex in shape, high in quality, and require good interchangeability, which cannot meet the above requirements on non-numerical control grinders, and can only be arranged to numerical control grinder processing, such as parabolic, cycloidal cam, and mirror mirrors of special profiles.

CNC lathe processing preliminary steps, first determine the parts of the process requirements, the processing of the workpiece batch, the development of numerical control lathe should have the function of pre-preparation, reasonable selection of numerical control lathe prerequisites, to 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 size accuracy of the workpiece, positioning accuracy and surface roughness requirements to choose the numerical control lathe processing accuracy.

According to the reliability to choose, reliability is the guarantee of improving product quality and production efficiency. The reliability of numerical control machine tools means that when the machine tool performs its functions under specified conditions, it runs stably for a long time without failure. That is, the average time without failure is long, even if there is a failure, it can be restored in a short time and put back into use. Select machine tools with reasonable structure, well-made and mass-produced. Generally, the more users, the higher the reliability of the numerical control system. Generally, imported systems include Japan‘s Sanling, Farnack, Germany‘s Siemens, domestic products have a wide number, Cairn Emperor, and the new generation are more commonly used.
