How To Solve The Small Problem Of Aperture Shrinkage in Deep Hole Processing?

Dec 06, 2021

Deep hole processing is a common technology in the machinery manufacturing industry. The ratio of hole depth to hole diameter is deep hole. There are three types of deep hole, medium deep hole and special deep hole. In the process of deep hole processing, how to solve the problem of aperture reduction?

For the problem of aperture reduction in deep hole technology processing, we need to find out the corresponding reason first. The problem of aperture reduction in deep hole processing is due to the following reasons: the cutting speed is too low; the design value of the outer diameter of the reamer is too small; the main deflection angle of the reamer is too small; the feed rate is too large; there is no wear part of the reamer during sharpening When worn off, elastic recovery makes the hole diameter smaller; no suitable cutting fluid is selected; the margin is too large or the reamer is not sharp, resulting in elastic recovery, resulting in shrinkage of the hole diameter and out-of-round inner hole, and the hole diameter is unqualified. After finding the cause, the problem of aperture reduction in deep hole processing was solved. We can appropriately increase the cutting speed; change the outer diameter of the reamer; appropriately increase the entering angle; appropriately reduce the feed rate; replace the reamer regularly and sharpen the cutting part of the reamer correctly; use a better lubricating oil-based cutting fluid; cutting Experiment before, determine the appropriate margin, sharpen the reamer; design the size of the reamer according to the actual situation.
