High precision: ER chuck can achieve high-precision clamping, usually with high concentricity and axial runout tolerance, which can meet the needs of precision machining Large clamping force: With the help of a wedge-shaped rod system, the ER chuck can provide a large clamping force, suitable for machining tasks that require strong clamping force Durability: The surface hardening treatment of the chuck body improves its durability and service life Easy to adjust: The design with visible markers makes adjusting the jawbone quick and convenient High corrosion protection: ER chucks have high corrosion protection capabilities and can work stably for a long time in harsh environments. These advantages make ER chucks perform well in mechanical machining, especially in machining tasks that require high precision and stability
