Pneumatic Precision Grinding and Polishing Machine (JRJM25-4/JRJM40-2)

Application

Designed for high-precision grinding and polishing of planar (flat) and spherical surfaces of optical glass, quartz, crystals, ceramics, silicon wafers, and sapphire.

Features

1.Motion Control: Spindle speed, oscillation (stroke/frequency), pressure, and processing time can be independently adjusted based on specific workpiece requirements.

2.Interface: Available with either Touchscreen HMI or Rotary Knobs.
