Oil hole center of grinding cutting working machine tool

摘要

The present invention relates to a center for holding a rotating workpiece during metal grinding and cutting machine tools.;According to the present invention, as shown in Figure 1, the workpiece 4 and the workpiece by forcibly lubricating the lubricating oil by the oiler (2) inside the workpiece center holding center (1) for holding the center of the rotary workpiece (4) An oil film is formed between the center holding centers 1 to reduce the generation of heat generated during high-speed rotation, thereby extending the precision and life of the work center holding centers 1. The forced lubrication-type workpiece center 1 is used for cylindrical grinding, tool grinding, gear honing, etc., which require metal grinding, such as lathe work, milling work, and tooth cutting work.
