Product Description
CNC Centerless Grinding Machine Overview
⚙
High Quality Construction: Utilizes high-quality cast iron with low frequency melting furnace treatment. Natural aging for 1.5 years eliminates internal stress, ensuring bed accuracy and zero deformation.
Machine Structure

Guide rail surface undergoes high-frequency quenching and manual scraping for high wear resistance.

Spindle System

Spindle made of SNCM-220H high-grade alloy steel from Japan, quenched and precision ground.

💧
Hydrostatic Pressure Patent: Spindle seat forms a high-pressure oil film (20-25KG/cm2), allowing the spindle to suspend without friction, ensuring ultra-long life and high rigidity.
Grinding Performance

Rotation accuracy < 1.5 μm. Grinding wheel speed up to 50m/s for optimal surface smoothness.

Automatic System

Capable of processing steps, chamfers, curved surfaces, and conical surfaces with high precision.
