HIGH-PRECISION PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a high-precision processing apparatus that can perform high-precision processing by preventing a tool from being bent due to processing loads such as cutting resistance and grinding resistance to.

SOLUTION: The high-precision processing apparatus includes a tool 4 having a columnar processing surface and rotating the processing surface by a rotary shaft 24, and performs processing by bringing the columnar processing surface of the tool 4 into contact with a workpiece 1 while rotating the columnar processing surface. The high-precision processing apparatus includes: a circling drive motor 5 for allowing the rotary shaft 24 of the tool 4 to circle in a horizontal direction relative to the workpiece 1; a torque sensor 17 for acquiring both output values of the circling drive motor 5 during processing and non-processing; a calculating part 14 for calculating the bending amount of the tool 4 relative to the rotary shaft 24 based on the output values of the circling drive motor 5 during processing and non-processing to determine the circling amount of a circling for balancing the bending amount; and a control part 16 for controlling the circling drive motor 5 so that the rotary shaft 24 of the tool 4 is situated by the circling amount of the circling.
