Claims

[Scope of utility model registration request]

A left-right feeding device for causing a grinding wheel correction head equipped with a grinding wheel correction tool to traverse the outer circumferential surface of a cylindrical grindstone, a cutting device for the grinding wheel correction tool that makes a cut for each traverse of the left-right feeding device, and a cutting device provided in the grinding wheel correction head. a contact detection sensor that detects a contact sound between the grinding wheel correction tool and the grinding wheel, and a timer whose time is set in correspondence with the time it takes for the grinding wheel correction tool to pass over the entire width of the grinding wheel to maintain the contact sound generated by the contact detection sensor. In the grindstone correction device for a cylindrical grindstone, the grindstone is equipped with a control device provided with a comparison circuit for comparing with the set time of An intermediate position detecting means is provided which is activated when the stop correction tool passes between the two, and a signal from the intermediate position detecting means resets a comparison circuit that compares the duration of the contact sound between the correction tool and the grindstone with a set time of a timer. A grindstone correction device for a plurality of cylindrical grindstones.
