Product Features

High rigidity spindle head

The spindle head has a robust structure and uses precision bearings for stable support. Whether it's outer diameter grinding, inner diameter grinding (optional), or end face grinding, it offers excellent precision.

Precision grinding wheel spindle

The grinding wheel spindle is precision-machined from high-grade alloy steel. It undergoes normalization, tempering, carburizing, and cryogenic treatment, followed by precision grinding and mirror finishing. The spindle exhibits no thermal deformation or wear, and achieves high grinding accuracy.

Grinding wheel spindle hydrostatic bearing
(Hydro-static)

The grinding wheel spindle uses a hydrostatic bearing, which eliminates all metal-to-metal contact friction. This special hydrostatic bearing design also enhances the spindle's rigidity and provides excellent shock resistance.

Tailstock lubrication system

The tailstock lubrication system uses an oil bath lubrication system to ensure the high precision of the tailstock at all times. The tailstock is equipped with an oil level gauge so that the operator can easily check the oil level.
