Product Spotlight

  • T-Style Clamping



    New Clamping mechanism allows clamping force to be applied not only downward but also pulling inward towards the tool body.

  • Clamping Rigidity



    Unique feature improves clamping rigidity and position accuracy which in turn would extend insert tooling life.

  • Locating Pin



    Locating pin on the front of the clamp makes an arc contact with the inner wall of insert hole, resulting an evenly distributed clamping force to be more secure and rigid.

  • Locating Lug



    Locating lug on the back of the clamp matches with the slot on the tool body to guide the clamp to be seated repetitively which would improve clamping accuracy.

YBC252 Black Diamond Carbide Grade

ybc252

YBC252 comprises of thick layer of TICN and Al2O3 in CVD coating process which yields anti-plastic deformation and strong cutting edge strength.  It's the preferred choice for machining steel from finishing to roughing.  It can achieve stable performance in high chip removal rate and large depth of cut or in adverse working condition, and it can also achieve dry cutting for environmental concerns

Perfect unification of toughness and anti-plastic deformation

skeleton

The two areas on the outside of the red line are ductile area of rich cobalt layer while the middle section contains cubic carbides of well high-temperature behavior.  This unique skeleton design on the cutting edge improves toughness and anti-plastic deformation.

 

Improved Surface Roughness

           Before Treatment                               After Treatment

Special surface treatment on the insert significantly lower the surface roughness, reduces the bonding between insert surface and work material, effectively improves the stability.

Combination of fibrous TICN and fine grained Al2O3 increases abrasion resistance and anti-chipping.

DM Chip Breaker 

DM chip breaker

preferred choice chip breaker on P category material semi-finish

M Class tolerance double sided chip breaker, light cutting force with wide chipping range, can achieve better result on high adhesive alloy steels.
