Development prospect of precision parts industry

The most fundamental factor for tool manufacturers and grinding plants to improve work efficiency and reduce costs lies in the continuous promotion of new products by machine tool manufacturers. In order to improve the utilization rate of machine tools and reduce labor costs, automation has been increasingly valued. At the same time, through the development of software, the machine tool can expand the operation function, and can economically arrange the production schedule under the condition of small production batch and short delivery period. In addition, increase the power of the machine tool so that it can adapt to diverse needs and broaden the specification range of the grinding tool.

In the future, the development of CNC tool grinders will be mainly reflected in three aspects:

1) Automation: When the tool manufacturer produces new tools, it is efficient because of the large volume. However, there is no such condition in the tool repair and grinding plant, and the efficiency problem can only be solved through automation. The tool grinder does not require the machine tool to realize unmanned operation, but hopes that one operator can take care of multiple machine tools to control the cost.

2) High precision: many manufacturers take reducing operation time as their primary goal, but others put part quality at the most important position (such as high-precision tool and medical parts manufacturers). With the improvement of grinding machine production technology, the newly developed machine tool can guarantee very strict tolerance and extraordinary finish.

3) Development of application software: Now the factory hopes that the higher the degree of automation of grinding, the better. Regardless of the size of the production batch, the key is to achieve flexibility. Luo Baihui, Secretary-General of the International Mould Association, said that the work of the Tool Committee of the Association in recent years has included efforts to establish an automatic loading and unloading system for cutting tools and grinding wheels, so as to achieve unattended or minimize the supervision of the grinding process. He stressed that the reason for the increasing importance of software is that the number of high-level workers capable of manually grinding complex tools is decreasing. In addition, the hand-made tools are also difficult to meet the requirements of modern machine tools for cutting speed and accuracy. Compared with CNC grinding, manual grinding will reduce the quality and consistency of the cutting edge. Because during manual grinding, the tool must rest on the support plate, and the grinding direction of the grinding wheel points to the cutting edge, which will produce edge burrs. On the contrary, CNC grinding does not need a support plate when working. If the grinding direction is away from the cutting edge, there will be no edge burr.
