Roller burnishing process of deep hole
A deep hole is a hole whose length proportion is greater than 10 to the diameter of the hole. In most cases, the depth ratio of L/d is greater than 100. Such as cylinder hole, axial shaft oiled hole, hollow main shaft hole and hydraulic valve hole, etc. The machining precision and surface quality of these holes are high. Moreover, some processed materials have poor cutting performance, which is often a major problem of production. However, as long as we...
