Description

BT series HGER hydraulic chucks are manufactured from high-strength alloy steel with overall vacuum quenching and precision grinding, the premium tool holding solution for high-speed, high-precision machining applications on BT spindle CNC machining centers.
  1. Hydraulic expansion clamping mechanism delivers exceptional concentricity with ≤0.003mm runout accuracy at 4×D from the chuck face, ensuring perfect machining precision and surface finish.
  2. Excellent vibration damping performance reduces tool chatter, extending tool life by up to 30% compared to standard ER collet chucks.
  3. High clamping force provides secure tool holding even at high rotational speeds, making it ideal for high-speed milling and drilling operations.
  4. Comprehensive size range supports HGER16, HGER20, HGER25 and HGER32 hydraulic collet systems, covering tool diameters from 3mm to 32mm, with multiple length options to accommodate various machining depths.
  5. Standard 7/24 taper design is 100% compatible with all mainstream BT30, BT40 and BT50 spindle CNC machine tools.
  6. Polished chrome-plated surface provides superior corrosion resistance and long-term durability in industrial environments.
