Stepped transmission shafts, engine crankshafts and precision bearing rings used in the bearing, reducer and engine industries, together with the processing of shaft parts required by the automotive industry, cannot be achieved without the application of grinding machines.

Precision finishing of hydraulic actuators for oil & gas wellheads and core parts of pumping unit hydraulic cylinders via CNC cylindrical grinders. These components operate under long-term high-pressure and wear-prone service conditions. The combined CNC traverse cylindrical grinding and plunge grinding process completes grinding of multi-step outer circles and arc transitions in a single clamping setup. This technology is also applicable to slender shafts such as sealed rotary shafts for downhole high-pressure control valves.
