Key Features
Superior Grinding Performance for Hardened Workpieces
Enables continuous grinding of HRC62 hardness workpieces for over 2 hours with a Z-axis feed of 0.2mm, eliminating the need for frequent wheel dressing—saving time and boosting productivity.
Delivers superior surface finish (R0.63μm) that exceeds industry standards, ensuring precision for critical components.
High-Precision Spindle & Transmission System
Grinding wheel spindle adopts an imported precision rolling bearing sleeve structure, guaranteeing high rotational accuracy and powerful cutting capabilities.
Grinding head’s lateral movement is driven by an AC motor and precision ball screw, supporting both automatic operation and manual control for groove grinding tasks.
Rigid & Stable Machine Structure
Square carriage with dense internal ribs enhances structural rigidity, minimizing vibration during heavy cutting and ensuring consistent machining quality.
Maintenance-free spindle design reduces downtime and operational costs, optimizing long-term usability.
User-Friendly Operation & Versatility
Vertical movement of the grinding head (by handwheel) offers precise control: 0.01mm per graduation and 1mm per revolution, enabling micro-adjustments for complex tasks.
Multiple model options with varying worktable sizes (1250×500mm to 2000×630mm) cater to diverse workpiece dimensions, from small precision parts to large components.
