PRODUCT NEWS No. 44 FU INEUP NEW TA-EZ TEZD "Indexable EZ DRI" TEZD type JCTMA 213-6 ECO PRODUCT 超硬工具協会 (JCTMA) 環境認定製品です "Indexable EZ DRI" achieved easy assembly and high cutting performance.
Indexable EZ DRI achieved easy assembly and high cutting performance. TA-EZ Indexable EZ DRI Features Eco-friendly Adopting unique low cutting force geometry (EZ geometry) reduced 3% power consumption. Cost reduction High rigid G-body produced long tool life of holders and inserts. High cutting performance Adopting unique cooling system achieved surely coolant supply to cutting edge. ine-up Body For bridge construction Hole depth D D D D Applicable dia. 1
Series Expansion TEZD-X type (8D) Exclusive flute geometry for TEZD-X type (8D) and smooth surface treatment achieved both body durability and excellent chip control. Adopting body clearance prevents welding deposit of chips on the body, and reduced cutting force and achieved longer tool life of body.

Procedure of mounting insert for TEZD 1 Removing the used insert Remove the used insert and clean the insert pocket by brush or air blow before mounting new insert. In case of blocking clamp pocket by chips and dust, please remove them before loosening the clamp screw. 2 Mounting the new insert Tighten the two clamp screws lightly with pressing the top of insert (,:initial tightning). After confirming that there is no gap, be sure to fix the insert completely by tightening the clamp screws again to the recommended torque (,:final tightning). And, please recommend to spread the attached MOY coat on the clamp screw in Attention Clamp screw is expendables, so please also exchange the clamp screw whenever you exchange inserts 1 times. But, in case there is the deformation of the clamp screw, exchange it immediately. Clamp screw Notice of when using lathe. 1. Check run-out of insert O.D. with in.3mm (off set of center with in.15mm) and flute O.D. of shank side with in approximately.3mm. 2. Due to large thrust cutting forces. Set back up plate at end of shank. 3. Reduce the cutting speed and feed rate 2% against recommended cutting conditions. In case long chip coming out of flutes, increase feed rate only. 4
