Characteristic

Model : 3X5CAT

This gripper series is designed for ASME B5.50 CAT30, CAT40, and CAT50 spindles, adopting an M45 mechanical force amplification system. It allows strong and stable clamping force in limited spindle space, making it ideal for high-speed and high-precision machining environments.

Fixed 45° clamping angle for efficient pulling and smooth releasing
Modular design ensures easy installation and maintenance
Male-threaded interface for standard pull stud attachment
Compatible with most CNC machines using CAT spindle interfac

Dimensional References (per drawing):

• Key dimensions include stroke (g, h, i, k), thread diameter (f), angle α = 45°

• Clamping Position (SS) and Release Position (LS) illustrated on technical diagram

• Torque direction MA and pull force Fs noted

Applications:

• CNC vertical or horizontal machining centers

• Automatic Tool Changer (ATC) systems

• High-torque tool holding for large-scale milling or aerospace machining

Usage & Maintenance Notes:

1. Confirm spindle internal contour prior to installation.

2. Grease thread and contact areas adequately before use.

3. Avoid asymmetric loading or dry running.

4. Always verify torque and force values during installation or replacement.
