1). Considering on customer have lot of different size rotor, we use special design about the machine construction, easy and fast for customer change different size rotor tooling.
2). After turning, the rotor surface is smooth, concentricity is good, and size accurate is good. and also high effient. The finish speed is 1-5 times more than outer grinding machine.
3). Suitable for middle and small motor rotor OD rough turning purpose.

The HF-C40 machine achieves a working speed of up to 600 pieces per hour. Its finishing speed is 1 to 5 times faster than standard outer diameter grinding machines, significantly optimizing production efficiency.
The machine standard handles rotor OD from 20 to 62 mm (custom SPM available for >62 mm), rotor ID from 4 to 25 mm (custom SPM available for >25 mm), and rotor height between 10 and 40 mm.
The turning cutting thickness can be finely adjusted within the range of 0.01 mm to 0.35 mm, delivering high precision, smooth surface finishes, and superior concentricity.
The equipment integrates high-tech oil pressure motors imported from Italy, along with premium hydraulic cylinders and oil pumps from Taiwan, guaranteeing long-lasting stability and durability.
Yes. The machine is engineered with a specialized modular construction that enables operators to switch between different rotor size fixtures easily and rapidly, minimizing downtime.
