Product overviewThe DZDC-125 cradle rotary head uses a cradle support for controlled tilting and continuous rotary positioning. Dual-axis oil cooling, 26-bit BiSS-C encoder feedback and separate vertical/horizontal workpiece load ratings support integration into machine tools and tool grinders.
Key features- Cradle structure for controlled tilt and continuous rotary positioning
- Dual-axis oil cooling for thermal stability
- 26-bit BiSS-C encoder for high-resolution positioning
- Workpiece load capacity: vertical 20 kg / horizontal 30 kg
- High clamping torque and substantial pull force for secure tool holding
