How to achieve the high precision of the cutting machine

Let's take a look at the explanation of the four-post cutting machine manufacturer.

1. Processing procedure

The main surface of the guide column is an inner cylindrical surface and an outer cylindrical surface. The processing procedures: inner cylindrical surface: drilling-rough boring-semi-rough boring-rough grinding-fine grinding; for outer cylindrical surface: rough turning-semi-finishing turning-rough grinding -fine grinding.

2. Hard chrome plating

After chromium plating treatment, the mold and workpiece have the following advantages:

1) The surface is smooth, smooth and easy to demould, in order to ensure the smoothness and smoothness of the product.

2) No rust, no rust spots at all.

3) In the process of plating, the original parts are small in deformation, and the surface layer can be increased in hardness (HR65 or above) after chrome plating, high temperature resistance up to 500, corrosion resistance, acid resistance, and wear resistance.

4) If the size of the part is not in place, it can be achieved by adding a few c chrome.

5) According to the characteristics of the product, it can achieve visual and three-dimensional effects to ensure the stable surface quality of the product.

3. The key technology and the measures taken

1) The main surface is an inner cylindrical surface, with a high dimensional tolerance level and a small surface roughness value Ra. Measures taken: Divide the processing stages, the process route adopts: drilling-rough boring (expanded)-semi-precision boring (reaming)-rough grinding-fine grinding-grinding; select machine tools; control cutting consumption; adequate cooling.

2) Because the outer cylindrical surface has a high dimensional tolerance level and a small surface roughness value Ra value, the measures taken are: the requirements for the division of processing stages, the selection of machine tools, and the control of cutting parameters are the same as those for the inner cylindrical surface processing. In addition, the process route is: rough turning-semi-finishing turning-rough grinding-fine grinding.
