CH2J series

2-Jaws High Precision Thru-Hole Chuck Series

Features

  • Suitable for clamping irregular shape objects for cutting process.
  • Adopts high strength alloy steel, main parts all with harden treatment to strengthen its stability , accuracy and daubility.
  • Extra Large thru-hole caliber design allowing the bar materials go through processing step even can go well with automation equipment to increase production capacity.
  • The chucks mating with rotary hydraulic cylinder are complementary , of which providing steady pressure v.s various chucking conditions.
  • Through professional fine-grinding for chucks, thus, it's with high precision, high clamping force and high repeatedly clamping accuracy.
