1. Main surface processing schemes of sliding guide post
The main surfaces of sliding guide post are inner cylindrical surface and outer cylindrical surface. The processing scheme of the main surfaces of sliding guide post is: inner cylindrical surface: drilling - rough boring (expansion) - semi rough boring - rough grinding - fine grinding; For cylindrical surface: rough turning - semi fine turning - rough grinding - fine grinding.
2. Positioning benchmark of sliding guide post
According to the principle of datum selection, the sliding guide post shall select the inner and outer cylindrical surfaces as the datum each other.
3. Heat treatment
The sliding guide post of different materials adopts different heat treatment methods. If the material of the guide sleeve is 20 steel carburizing, the heat treatment is carburizing, quenching and low-temperature tempering; If the guide sleeve is made of T10A Steel, the heat treatment is quenching and low temperature tempering.
4. Key technologies and measures taken
(1) If the main surface of the sliding guide post is the inner cylindrical surface, at the same time, the dimensional tolerance grade of the inner cylindrical surface is high and the surface roughness Ra value is small. The measures taken are: divide the processing stage of sliding guide post, and the process route is: drilling - rough boring (expansion) - semi fine boring (hinge) - rough grinding - fine grinding - grinding; Select precision machine tools; Control cutting parameters; Sufficient cooling.
(2) If the main surface of the sliding guide post is an outer cylindrical surface, at the same time, the dimensional tolerance grade of the outer cylindrical surface is high and the surface roughness Ra value is small, 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 machining of the inner cylindrical surface. In addition, the process route of sliding guide post at this time is: rough turning - semi fine turning - rough grinding - fine grinding.
