- Flat, Non‑Serrated Front Face Designed for Grinders
The JPL adopts a flat, non‑serrated front face, eliminating the 1.5mm step‑feed limitation of serrated tooth structures found in the JP series. This design supports the fine incremental adjustments required in grinding operations.
- Significantly Reduced Jaw‑Truing Time
The JP series requires approximately 1.5mm of jaw movement per step due to its serrated interface, resulting in excessive material removal on grinders. The JPL’s flat face allows extremely small jaw movements, effectively shortening jaw‑truing time.
- High Precision Inherited from Diaphragm Chuck Design
Maintains the inherent advantages of diaphragm chucks—high repeatability, low deformation, and stable clamping force—ideal for precision OD, face, and profile grinding.
- No Sliding Components, Long‑Lasting Accuracy
With no sliding parts, the chuck requires no lubrication and has no wear‑related backlash issues, maintaining stable accuracy during long‑term operation.
- Gentle Clamping Force Achievable Under Standard Hydraulic Pressure
The diaphragm mechanism provides gentle, evenly distributed clamping force without the need to reduce hydraulic pressure, ensuring stable performance for delicate workpieces.
- Ideal for Thin Rings, Thin Tubes, and Fragile Components
Compared with hydraulic 3‑jaw chucks, diaphragm chucks minimize clamping deformation, making them highly suitable for thin‑wall or fragile parts.
