What problems should be paid attention to precision slender shaft cutting?
Jan 04, 2018

First of all, we're going to give you a definition of the slender shaft,usually we call a slender shaft with a diameter of more than 20 to 25 times the diameter of a work piece.So what problems that need to be paid attention to them in the process of cutting?Let's look at the details.

In comparison, the rigidity of the slender shaft is poor.Usually, the greater the L/d value, the worse its rigidity.Therefore, there may be some abnormal problems in the process of turning, for example, because the work piece is affected by the cutting force, self-weight and centrifugal force of rotation, it is possible to bend and vibrate.In severe cases, it may even affect its cylindric and surface roughness.

In addition, in the process of cutting the shaft, due to the influence of thermal action, there will also be a certain bending deformation.This will make it very difficult to cut and even cause the work piece to get stuck at the top.

Therefore, in the process of processing the slender shaft, the whole process requirements are actually relatively strict and difficult.Although the processing difficulty is bigger, but it has certain regularity.That is to say, as long as we seize the center to use with the frame and the carrier, to solve thermal deformation and elongation, choose reasonable tool geometric shapes such as the three key technologies, then we can solve these problems.

For example, if you want to minimize the heat distortion of the shaft, the effective measures can be taken as follows:1. Use elastic turning center;2. Injecting sufficient cutting fluid;3. The cutter remains sharp.

In fact, the first measure can make up for the thermal deformation and elongation of the shaft, and it can prevent the bending of the shaft, which can ensure smooth turning.And the sufficient cutting fluid can avoid the thermal deformation caused by the temperature rise of the shaft.http://www.xhychromerod.com/
