2-Jaw Extra Large Caliber Thru-hole Precision Chuck Series

2-Jaw Extra Large Caliber Thru-hole Precision Chuck Series

CBH2J series

Features
  • Suitable for clamping irregular bar-shape objects for cutting process.
  • Extra Large caliber thru-hole design: the thru-hole dimension is much larger than standard one thus ideal for large dia. Bar objects' processing.
  • Adopting high-strength alloy steel with harden treatment , thus  with features of high intensity, rigidity and life-span.
  • Through professional fine-grinding for chucks, thus, it’s with high precision,high clamping force andhigh repeatedly clamping accuracy.
  • The chucks  with  rotary hydraulic  cylinder  are complementary , of which providing steady pressure v.s various chucking condition.
