Product Overview

Product Features

1. Dual-Spindle Collaborative Design, Efficient Parallel Processing

The machine adopts a vertical dual-spindle layout. Both spindles can operate independently and collaboratively, performing multi-process composite grinding on workpieces, significantly improving processing efficiency. Compared to traditional single-spindle grinders, production efficiency is increased by more than 30%.

2. Ultra-Precision Grinding Accuracy Control

Dimensional accuracy up to ±0.002mm, roundness and non-circular profile accuracy controlled within ±0.001mm, ID/OD coaxiality stable at 0.002-0.003mm, surface roughness as low as Ra: 0.2-0.4μm.

3. Dedicated Grinding Process Optimization

Optimized grinding path and wheel selection design, using dedicated grinding algorithms to effectively reduce grinding marks; equipped with grinding fluid circulation and filtration system to ensure grinding fluid cleanliness.

4. High Stability and Reliability

Key components are selected from internationally renowned brands. The machine body adopts a symmetrical structural design with low center of gravity and strong stability, effectively resisting impact forces and vibrations during the grinding process.

5. Flexible Adaptation Capability

Can flexibly adapt to processing cylindrical parts of different specifications and materials. Through quick tool change and parameter adjustment, multi-variety, small-batch production can be achieved.
