Title:
INTERNAL GRINDING MACHINE
Document Type and Number:
Japanese Patent JP2010076004
Kind Code:
A
Abstract:
To provide an internal grinding machine capable of accurately detecting a grinding force.
A grinding force detection means comprises a first force sensor 31 fitted to a first shoe 21, a second force sensor 32 fitted to a second shoe 32 arranged at the position separated by 90 in the circumferential direction from the first shoe 21, and a signal processing means for obtaining a grinding force by taking the difference between output values by deviating the phase by a 1/4 period corresponding to the separation of 90 in the circumferential direction of the force sensors 31, 32 based on the output value of the first force sensor 31 and the output value of the second force sensor 32.
