PROCESSING APPARATUS WITH MOVABLE PROCESSING TOOL

摘要

A processing apparatus with a movable processing tool, includes a deflection detecting device, a rotating position detecting sensor, an arithmetic unit, an output circuit, a fine adjustment device, and an XY table. The detecting device detects a plurality of deflection amounts of a processing reference surface of a to-be-processed work held by a work holding member mounted to a main shaft of an NC processing apparatus. The sensor detects a rotating position of the work. The unit calculates a correcting amount of the tool at a processing point of the work from a measured value of the sensor and plural measured values of the deflection amounts of the detecting device. The circuit outputs the correcting amount synchronously with the rotating position and processing point of the work. The adjustment device has the tool fixed thereto for finely moving the tool in a processing direction based on an output from the circuit. The fine adjustment device is secured to the XY table.
