As a manufacturer of precision mold parts processing, we have extremely high requirements for chuck positioning accuracy, and this 4-jaw chuck fully meets the standard! When clamping a Φ50 eccentric shaft, by adjusting the four jaws individually, we can easily achieve precise positioning with an eccentricity of 5mm. Monitoring the entire processing process with a dial indicator, the eccentricity deviation is always controlled within 0.008mm. The processed eccentric shaft is assembled into the mold and runs very smoothly. The chuck is made of high-strength cast iron with good rigidity, no chuck deformation during processing, and the accuracy remains stable after three months. It has much higher cost-effectiveness than imported chucks!
