A grinding tool kit, apparatus and method for finish machining of a rolling surface of a bearing roller. The apparatus comprises a main machine, an external circulation system, a grinding tool kit and a grinding tool kit clamp. A configuration of the main machine comprise a grinding strip assembly rotary type and a grinding sleeve rotary type. The external circulation system comprises a collection unit (), a sorting unit (), a feeding unit () and a transmission subsystem. The grinding tool kit comprises a grinding sleeve () remaining coaxial during working, and a grinding strip assembly penetrating through the grinding sleeve (), an inner surface of the grinding sleeve () is provided with a first spiral groove (); and the grinding strip assembly comprises a plurality of grinding strips (), front surfaces of which are provided with linear grooves () or second spiral grooves distributed in a circumferential columnar array.

Grinding tool kit, apparatus and method for finish machining of rolling surface of bearing roller

A double-disc straight groove cylindrical-component surface grinding disc, includes a first grinding disc and a second grinding disc, rotating relative to each other; the the first grinding disc's working face is planar; the second grinding disc's surface, opposite the first grinding disc, includes a set of radial straight grooves, with groove faces of the straight grooves are the working face of the second grinding disc; the cross-sectional outline of the working face of the second grinding disc is arcuate or V-shaped or is a V-shape having an arc; during grinding, a workpiece spins inside the straight grooves, while under the effect of an advancing apparatus, the workpiece slides in translational motion along the straight grooves. The described grinding disc device has high-volume production capabilities, and the shape accuracy and size consistency of the cylindrical roller's cylindrical surface and the efficiency in machining are improved, and machining cost is reduced.
