CBH3J series
3-Jaw Extra Large Caliber Thru-Hole Precision Chuck Series
Features
- Suitable for clamping round-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.
