High Rigidity Superior Shock Resistance BT-C Mill Chuck For Milling Machine

1. High steel, superior shock resistance, using 20CrMnTiH high quality steel. Long service life, carburizing quenching process, high surface hardness, strong fatigue resistance and high wear resistance, keep the heart with low carbon steel quenching strong toughness, so that the shank can withstand a certain impact and load, this shank carburizing quenching hardness ≤ HRC56 degrees, carburizing depth > 0.8 mm.

2. Double dustproof design, thickened inside and outside. Clamping fastening force is uniform, effectively avoiding the internal rusting of the shank stuck and other phenomena, while avoiding iron chips stuck shank mouth during processing; thickened inside and outside to withstand heavy cutting of the tool.

3. Adopting unique clamping structure, it can use the clamping part to deform evenly to obtain strong clamping force and stable runout accuracy.
