4-Jaws High Precision Thru-Hole Chuck Series

4-Jaws High Precision Thru-Hole Chuck Series

CH4J series

Features
  • Suitable for  clamping square or irregular shape objects for cutting process.
  • Adopts  high strength alloy steel,  main parts all  with harden treatment  to strengthen its stability , accuracy and Duability.
  • 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.
