CNC precision machining is this kind of processing equipment to carry out changes to the size or function of the product. According to the temperature condition of the product being produced and processed, it is divided into cold processing and hot processing. Precision cnc precision machining is usually specifically for precision machinery and equipment parts to carry out production processing production, which should be done with very high precision, so we should not only know the details of precision cnc precision machining of raw materials and precision mechanical parts processing often use methods, but also deserve to know the production and processing process of precision mechanical parts processing what are the method steps, the next one get up to know it!
1. Rough machining; the consideration is to improve the productivity. Most of the remaining amount of machining on each surface is cut off, and a finishing standard is produced.
2. Semi-finish machining: The defects that are likely to be formed after rough machining are cut off, and the secondary surface layer is produced and machined at the same time. It is necessary to achieve the corresponding machining accuracy in order to prepare for the finishing process and to ensure a moderate amount of finishing remaining.
3. Finishing process; in the finishing process, the primary use of large feed rate, small feed rate and cutting depth to cut off the remaining amount of semi-finishing process, so that the surface layer of precision mechanical parts to meet the technical specifications and requirements of the design drawings.
4. finishing production processing; mainly used to reduce the appearance of roughness or strengthen the production and processing of the surface layer, mainly used in the appearance of roughness to be very high surface layer production and processing.
In the development of the processing process, usually also in accordance with the specific operation of the confirmed development of changes to improve socio-economic benefits. In the production process, it is also likely to encounter unexpected conditions, such as changes in production conditions, changes in production technology, etc., in accordance with the actual situation of the processing process to carry out moderate adjustments.
The above is for the Dongguan machinery spare parts processing factory to sort out a few aspects, I hope it will help you!
