Title:
METHOD AND DEVICE FOR CONTROLLING CONSTANT SIZE WORKING OF MACHINE TOOL
Document Type and Number:
Japanese Patent JP3787248
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solver a problem that in a twin head grinder for separately working different working parts at the same time with two grinding wheels, sometimes the grinding cannot be performed at the same time, and when one of twin heads performs the spark-out during the working by the other one, resistance is applied to a work from one grinding wheel so as to deflect the work, and the spark-out is not performed.
SOLUTION: In this invention, the grinding wheel at the working part, in which a process just before the spark-out process reaches the final target dimension, is moved backward by the predetermined quantity, and when working at the other working part reaches the final target dimension, the other grinding wheel is moved backward by the predetermined quantity, and the spark-out is performed by both the grinding wheels at the same time so as to securely perform the spark-out.
