PALMARY GU20x40S Universal Cylindrical Grinding Machine

The high-precision cylindrical grinding machine PALMARY GU20x40S is unmatched in structural rigidity, operational stability, grinding accuracy, and ease of operation.

Stable and Rigid Workhead. The workhead spindle runs on high-precision bearings, providing maximum stability. This guarantees exceptional accuracy when grinding outer diameters, internal bores (optional), and shoulder faces.

Special Hydrostatic Bearing System. The grinding wheel spindle operates on a specialized hydrostatic bearing system, perfectly suited for ultra-precision grinding. Key advantages include high speed, zero metal-to-metal friction, no thermal deformation, and non-wearing long-term precision retention.

Grinding Wheel Spindle. Manufactured from premium alloy steel, the grinding wheel spindle undergoes advanced heat treatment: case-hardening, sub-zero cryogenic treatment, precision grinding, and mirror-finish superfinishing.

A single PALMARY GU20x40S grinding machine delivers:

• Straight cylindrical grinding;
• Plunge and shoulder grinding;
• Traverse grinding;
• End-face grinding;
• Taper grinding;
• Internal grinding (optional attachment).
