Deep hole drilling and boring machine is a common processing equipment in deep hole processing. In actual processing, the processing efficiency of deep hole drilling and boring machine plays an important role in the whole deep hole processing process. Therefore, improving the working efficiency of deep hole drilling and boring machine can greatly shorten the deep hole processing cycle and improve the production and processing efficiency. The two main factors that determine the working efficiency of deep hole drilling and boring machine are: cutting speed and feed speed. In order to achieve the best machining efficiency, we need to pay attention to the following aspects:
First, ensure the coaxiality of drill pipe support, tool guide sleeve, headstock spindle and drill pipe box spindle.
Second, control the stepless adjustment of the feed speed of the deep hole boring machine.
Thirdly, the cutting fluid system should maintain enough pressure and flow, and control the cleanliness of the cutting fluid.
Fourth, pay attention to the index displayed in the intelligent control of the machine tool at any time, such as the spindle load table value, feed speed, cutting fluid pressure, cutting fluid flow control, cutting fluid temperature and other values, which are controlled within the allowable range.
Fifthly, before the bit is drilled in, make sure the tool guide position is accurate.
