Product Uses

1. CNC Lathes, Milling Machines, and Machining Centers

Ensure tool stability during high-speed rotation and heavy cutting. Enable quick tool changes and precise positioning for milling, drilling, tapping, and other operations. Widely used for multi-face finishing of housings, molds, and structural parts, supporting high rigidity clamping requirements.

2. Mold Manufacturing Industry

In precision mold processing (e.g., injection molds, die-casting molds), tool holders must maintain extremely high positioning and repeatability accuracy to improve cavity surface quality and extend mold life.

3. Automotive Parts Machining

For complex components like engine blocks and transmission housings, tool holders withstand multi-axis movements and heavy loads, ensuring machining accuracy and batch consistency, crucial for automated production.

4. Construction Machinery and Heavy Industry

For rough and semi-finish machining of large castings and welded parts such as excavator structures and hydraulic components, tool holders require strong clamping force and vibration resistance to ensure safety under deep cuts and high feed rates.


Product Operate Guide

1. Before installation, confirm that the tool holder model matches the machine interface and that the tool dimensions and clamping method are compatible.

2. Clean the taper shank of the tool holder, spindle, and clamping area before use to prevent unstable clamping, excessive runout, or damage to contact surfaces.

3. Properly clamp the tool according to the tool holder structure, and use a torque wrench to tighten bolts to the recommended torque to avoid over-tightening or loosening.

4. After installation, check concentricity and runout to ensure machining accuracy.

5. If vibration, abnormal noise, or rough workpiece surface occurs during machining, stop the machine immediately for inspection.

6 .Regularly inspect clamping force and surface wear of the tool holder; apply lubrication and remove rust and debris as needed.
