Five requirements for machining of mechanical parts for CNC machining center:
1. CNC has high machining accuracy and stable quality
The machining process of CNC machining center machine tool is controlled by the computer according to the pre input program. As long as the information command is correct, the accuracy of CNC lathe can be ensured, so as to prevent the difference of product quality caused by the difference of operator's technical level. We know that the CNC machining center has a high repeatability in processing parts. When processing the same batch of parts, it can ensure the uniformity and stability of processing, and the processing of CNC parts will not be affected by human factors.
2. CNC has strong processing capacity and high flexibility
The key to the operation of CNC machining center lies in the processing program. When machining different parts, you can quickly reach the processing requirements by simply compiling or revising the processing program from scratch, without adjusting the operation of the machine tool. This greatly shortens the technical preparation time for replacing the machine tool hardware, so CNC is suitable for the production of multiple types, single pieces or small batches of parts. For parts with messy shapes, it is impossible for general machine tools to complete, while CNC machine tools only need to prepare corresponding programs, and can also complete the processing of some precise and messy parts.
3. Reduce labor intensity and improve working conditions
The processing process of CNC machining center is automatically completed according to the processing program. In general, the operator generally carries out panel operation, workpiece loading and unloading, tool preparation, central measurement of key processes, and query of machine tool operation. There is no need for deep and repetitive manual operation, which reduces the physical labor of employees, and correspondingly improves the working conditions.
4. CNC machining center has high processing efficiency and low cost
The movement speed of the moving parts of the CNC machining center is fast in empty travel. It is almost unnecessary to adjust the machine tool from scratch to replace workpieces, and the machining accuracy is relatively stable. Generally, only the first article inspection and the sampling inspection of key dimensions between processes are carried out, which greatly reduces the auxiliary production time of equipment, shutdown inspection, etc., improves the processing productivity, reduces the processing cost, and the larger the production batch, the lower the processing cost.
5. Good economic benefits
The advantage of machining technology of mechanical parts in CNC machining center is that when the machining target is changed, only the machining program needs to be written from scratch, and no new machine tools need to be manufactured or replaced. For parts with disordered shapes and high accuracy, the use of CNC lathes can correspondingly reduce the types and number of general lathes, effectively save equipment investment, and help enterprises to better develop reproduction. In the case of single piece and small batch production, the use of CNC parts processing can reduce the time for adjustment, processing and inspection, and directly save production costs. The NC machining quality is stable, which can reduce or even prevent the occurrence of waste products, reduce the production cost, and then obtain good economic benefits.
