MULTI LOCK MILLING CHUCK

P. 31
Same Appearance, but a Remarkable Improvement can be found when cutting.
The cutting chips show us the actual machining capability
Quiet, high speed heavy milling
Stable finishing
No Chattering of Heavy Milling.
Cutting Data HSS Endmill • Carbide Endmill 3 New Clamping at Root & Anti-Vibration Mechanism
5 Stable Milling with Stopper Wear of the bearing surface is only 1 ~ 2microns even after practical use of 4 ~ 5years owing to the use of 140% more needle rollers than imitations, the use of special material ( steel ) of NIKKEN own. and the know-how of hardening. The stopper is therefore located to the MULTI-LOCK Milling Chuck where the maximum efficiency of chucking torque is exerted. Tightening the chuck close to the flange face gives a sign of “ MILLING OK ” to ensure smooth, stable and reliable milling work. Easy for “ anyone to attain a stable torque. ” (Important : Good production with Assurance!!)

The End Mill can perform at 100% of their capability by using the cutting data. If cutting condition is exceeded, they may cause tool failure. For the M/C with ball guide mechanism, MAJOR DREAM HOLDER might perform better than MULTI-LOCK milling chuck. 4 Clamping at Nose Mechanism Clamping at nose - key Condition for Precise Milling. Surface Finish and Tool Life are decided by Clamping at Nose, Rigidity and Run-Out Accuracy. Only our mechanism performs real clamping at nose, never rivalled by imitations : ideal for heavy milling to fine finishing. Only the NIKKEN MULTI-LOCK Milling Chuck perfectly clamps even at 3mm from chuck nose.
6 Fine Run-Out Accuracy
Only NIKKEN MULTI-LOCK Milling Chuck can obtain the run-out accuracy within 5 μ m ( T. I. R ) at the position 100mm apart from the nose. ( C32 Style )
