Product Overview
Dual-Spindle Coordination, Single Setup Multi-Surface Precision Grinding
Five Core Advantages
⚙
Dual-Spindle Coordinated Design
OD and ID grinding spindles operate in parallel, completing ID, OD, and face grinding in a single setup, significantly reducing machining cycle time.
🎯
Ultra-Precision Grinding Accuracy
Positioning accuracy ±0.002mm, repeatability ±0.001mm, full closed-loop linear scale control ensures stable and reliable machining quality.
🔧
Specialized Grinding Process Optimization
Deep optimization of grinding parameters and process paths for heavy, large, cylindrical, disc, sleeve, and ring parts to achieve optimal machining results.
🛡
High Stability & Reliability
Hydrostatic spindle, crossed roller bearing worktable, and cast iron body ensure long-term stable high-precision operation.
🚀
Flexible Adaptability
5 models covering Φ50~Φ1610 grinding range, with flexible electromagnetic/permanent magnetic chuck switching, suitable for multi-variety small-batch production.
