HM-15Z CNC Grinding Machine for Precision Motor Rotor Grinding with Automatic Detection
Product Overview

The HM-15Z CNC Grinding Machine is a specialized precision grinding machine developed for motor rotor grinding, cylindrical grinding, shaft grinding, outer diameter grinding, and high-accuracy workpiece finishing. It is designed for manufacturers requiring stable grinding accuracy, automatic detection, real-time compensation, and efficient batch production of motor rotors and precision shaft components.

The machine comes standard with an automatic workpiece detection system, which can detect dimensional changes caused by grinding wheel wear in real time and automatically compensate for size variation. This helps maintain consistent grinding accuracy, reduce manual adjustment, and improve production stability.

The HM-15Z adopts a large-span rectangular bed with a thick-wall structure, providing excellent rigidity, vibration resistance, and torsional strength. The Cartesian coordinate system is arranged according to the design principle of planar elevation, ensuring balanced axis load, consistent dynamic response, and stable grinding accuracy.
