Claims

A headstock that rotatably supports the workpiece,
A grinding wheel for grinding the workpiece,
Truer for truing the grinding wheel,
A sensor for detecting the surface roughness of a grinding object which is any one of the objects other than the workpiece, which is ground by the grinding wheel.
A control device for controlling the truing of the grinding wheel,
The control device is
After performing truing for the grinding wheel, the number of grinding execution number setting unit in which the number of the workpieces to be ground before performing the next truing is set as the number of grinding executions,
After truing by the truer, a grinding number counter for counting the number of the workpieces ground by the grinding wheel,
A truing timing determination unit that determines whether or not the number of workpieces counted by the grinding number counter has reached the number of grinding operations;
Based on the detection result of the sensor, it is determined whether or not the currently set number of grinding operations is appropriate, and based on the determination result, the number of grinding operations for resetting the number of grinding operations to be used next time or later. A grinding machine system including a determination unit.

The object to be ground is the workpiece finished grinding by the grinding wheel,
The sensor detects the surface roughness of the workpiece at a position different from the processing area,
The grinder system according to claim 1, wherein detection of the surface roughness of the workpiece as the object to be ground by the sensor is performed in parallel with the grinding of the workpiece by the grinding wheel.

The sensor is
The grinding machine system according to claim 2, wherein the surface roughness is detected only for one of the workpieces ground immediately before performing truing.

The sensor is
The grinding machine system according to claim 2, wherein the surface roughness is detected for the plurality of workpieces ground immediately before the truing.

The grinder system is
A contact detection pin for measuring the outer diameter of the grinding wheel by contact with the grinding wheel,
The object to be ground is the contact detection pin,
The grinder system according to claim 1, wherein the sensor detects a surface roughness of the contact detection pin that comes into contact with the grinding wheel immediately before performing truing.

The grinding machine system according to claim 5, wherein the detection of the surface roughness of the contact detection pin by the sensor is performed in parallel with the truing of the grinding wheel by the truer.

The sensor is
Board,
A light emitting element mounted on the substrate and emitting light toward the workpiece;
A light-receiving element mounted on the substrate in the vicinity of the light-emitting element and capable of receiving reflected light from the workpiece,
A surface roughness calculating unit based on the amount of light received by the light receiving element,
The grinding machine system according to any one of claims 1 to 6, further comprising:

The grinder system is
The headstock, the grinding wheel, a plurality of grinding machines including at least the truer, and an analysis unit provided on a network to which the plurality of grinding machines are connected,
The grinding number determination unit is provided in the analysis unit, and performs the determination and the resetting based on data transmitted from the plurality of grinding machines, The grinding according to any one of claims 1 to 7. Board system.
