PURPOSE:To sharply improve the performance of a mirror surface processing machine by making the tip of a cutting tool adjustable to a work by 0.01 deg. in the fine adjustment of angle when using a diamond bite holder useful for a flycut type mirror surface processing machine. CONSTITUTION:The outside of a tool holder 11 to hold a cutting tool 10 is formed with a thin cylinder 12 to provide the whole holder 11 with a spring-like elasticity. For fine adjustment of the tip angle of the bite 10, the tip of a column 14 inside the holder 11 is pushed by use of a screw 13 to cause a fine elastic deformation to the cylinder 12. At this time, the displacement of the screw is not directly transmitted to the tip of the tool 10, but the reduced displacement due to the elastic deformation of the cylinder 12 is transmitted. Therefore, at the tip of the tool 10, it is possible to make a fine angle adjustement by a unit of 0.01 deg.. In this way, a time for tool angle adjustement can be sharply shortened and the performance of the mirror surface processing machine can be greatly improved. |
