The loss of deep hole processing during operation.

Deep hole drilling is a relatively strong hole processing technology. Generally, special deep hole cutters and special machine tools are required for processing, and a large amount of circulating cutting oil is required to complete chip removal and cooling, lubricating the tools, and cutting The large consumption of oil will not only increase the processing cost, but also cause oil pollution to the processing site, threatening the health of the operators. At the same time, the treatment of oily iron filings will cause air and environmental pollution. Dry machining using cutting fluid or sub-dry machining using a small amount of cutting fluid is one of the development directions of deep hole machining technology.

Deep hole drilling processing is a kind of hole processing technology that is difficult to process in mechanical processing, with higher technical content, higher degree, and higher processing cost. Generally, only the production units with higher degree and strong technical force have this aspect. Due to the large-scale use of deep-hole parts in petroleum, aviation, military, and construction machinery industries, such large-scale production units generally have large-scale deep-hole processing workshops and large-scale production every year. Batch and output value.

Deep hole processing technology is different from the traditional processing method of drilling with twist drills. Generally, special deep hole drills, special machine tools and complex accessories are used to complete. In the processing, a large amount of circulating cutting fluid is used to complete chip removal, cooling, and cooling. Lubricating tools, cutting fluid consumption is large, not only will cause oil pollution to the processing site, threatening the health of the operators, but also the treatment of oily iron filings will cause secondary pollution of the air and the environment", increasing manufacturing costs. Therefore, how to reduce processing costs and eliminate environmental pollution is the study of deep hole processing technology.
