Equipment Advantages

1. The machine bed, rotary spindle housing, grinding wheel headstock housing, and feed carriage are all integrally cast and machined on high-precision machine tools, ensuring a stable machine structure.

2. Equipped with Mitsubishi’s motion control system and original‑equipment motors, ensuring stable long‑term operation and precise machining accuracy.

3. The rotary spindle and workholding fixture are independently developed and assembled in-house, with precision exceeding industry standards.

4. The grinding spindle employs a hydrostatic–hydrodynamic bearing design, offering high precision, excellent rigidity, and a low failure rate, making it well suited for heavy-duty grinding operations.

5. The equipment is PLC-controlled, equipped with a touch screen, features robust programming capabilities, and is simple and easy to learn to operate.

6. The equipment employs a vertical machining configuration, offering inherent advantages for processing large components and delivering high grinding accuracy.

7. The equipment is equipped with two sets of grinding systems—one on each side—enabling both rough and finish grinding, as well as internal and external cylindrical grinding, to accommodate different workpieces.
