1 PRODUCT NEWS No.5 SERIES EXPANSION BNM typebnm-c type RNM typernm-c type MBN typembn-h type / MRN typemrn-h type MIRROR BALL MIRROR RADIUS

2 MIRROR BALL BNM BNM-C MIRROR BALL carbide shank series are possible to machine deeper mold making with consistent machining and high accurate finishing at high speed cutting, due to the increase tool rigidity and minimize the vibration. MirrorS BNM-S/ BNM-TG/BNM-S-R ''Mirror S'' insert is suitable for high hardened material in high speed cutting and can cut more smoothly. MIRROR BALL GRM Reduced the hand finishing and try out times by improved surface quality. Body durability is higher than ball nose end mill with same radius, therefore prevents chattering problem, and larger pick feed improved machining efficiency. Possible to high precision & high efficient machining even in case of general machine.

3 Indexable Ball Nose and Radius End Mills Combination MSN Modular Head series HRM MBNMBN-H MRNMRN-H MIRROR RADIUS End Mill RNM RNM-C HRMFRM to times higher efficient machining can be possible compared with conventional steel body, due to control the vibration by the combination of tuff modular system. Machining time is greatly shortened and cost reduction is achieved. Accuracy of MBN & MRN after combined O.D. run out : below 5μm (Target below 0μm) Corner radius accuracy : within 0μm / Bottom edge run-out : below 5μm (In case of mounting RNM type insert). Realization of excellent high precision machining. MIRROR RADIUS is able to use from roughing to finishing by wide variation in inserts. Series extended : FRM type insert with longer periphery straight edge, side & bottom face finishing for hardened steel, etc.

4 BNM "MIRROR BALL" Indexable Ball Nose End Mills Features. Ultimate precision indexable ball nose endmill with two effective teeth Radius form accuracy : below 0m fixed to holder (Radius form accuracy of insert : below m) In case of mounting BNM insert. Possibility of equal or more high precision machining comparing with solid ball end mill machining.. Precision clamp screw mounting Easy and strong clamping and accurate location mechanism by using the single precision clamp screw gives high repeatability and rigidity.. Round shape insert with improved edge sharpness Adopting the round shape insert can reduce the risk of vibration even in perpendicular wall millimg and cut smoothly for intricate form in high speed copy milling. MIRROR BALL Carbide Shank MIRROR BALL carbide shank series are possible to machine deeper mold making with consistent machining and high accurate finishing at high speed cutting, due to the increase tool rigidity and minimize the vibration.. By adopting carbide shank, tool rigidity is equal to solid carbide ball end mill.. Tool life increased to twice the tool life comparing with MIRROR BALL steel shank is possible.. Carbide shank can be adopted to shrink fit type holders. Initial cost 55% reduction Solid tool MIRROR BALL Body+Insert Running cost % reduction Solid tool Regrinding+Coating cost MIRROR BALL Insert cost Cost performance MIRROR BALL finishing can replace with conventional solid carbide ball nose end mill finishing. By adopting economical indexable insert, tool costs of finishing process can be reduced greatly without using solid carbide ball nose end mills. Tool dia. 0mm

6 BNM "MIRROR BALL" Indexable Ball Nose End Mills Attention Attention to mounting head and MSN/ MGN shank holder. Tightening procedure Cleaning Remove dirt and chips with air from the connecting thread and shank holder. Initial Tightening Tighten by hand until the head and the shank holder faces meet. Final Tightening Tighten slowly with torque control spanner wrench or DIJET DS type spanner wrench and confirm that there is no gap. Attention : Final tightening without initial tightening cause connecting thread break. NOTE:. Only use the torque control spanner wrench or DIJET DS type spanner wrench.. Please turn the spanner wrench slowly during use.. Please confirm that there is no gap. Thread M M M0 M M Tightening Torque.0Nm Nm Nm 0Nm 5Nm Spanner size 0,, 5 7, 9, Note). Modular heads are supplied without spanner wrench.. In case of choosing torque control spanner wrench, confirm that the wrench size is match to the dimensions W & C of each modular head. (There are some cases that modifying the thickness of spanner wrench is necessary.). mark shows: DIJET have a stock of DS- and type spanner wrenches. Caution for the mounting to shrink fit holder.. In case of modular head and carbide shank holder. When you use a carbide shank and a modular head on the shrink fit holder, please shrink fit the only carbide shank without mounting a modular head together. Please mount a modular head after shrinking fit. Note) If it shrink fit with mounting a modular head, the head and insert will become difficult to loose.. In case of carbide shank end mill (C Body) When you use a carbide shank end mill (C Body) on the shrink fit holder, please shrink fit the only carbide shank end mill without installing insert and clamp screw. Please fix the insert with tightening the clamp screw after shrinking fit. Note) If it shrink fit with the insert and clamp screw, the insert and the clamp screw will become difficult to loose. 5

41 RNM "MIRROR RADIUS" Indexable End Mills MIRROR RADIUS End Mill RNMtype "MIRROR RADIUS" Indexable End Mills Features. High precision indexable end mill with two effective cutting edges. Corner radius accuracy: within 0m (In case of mounting RNM type insert). High precision and high rigidity clamping system. Adoption of the same clamping system as the MIRROR BALL. This system already has wide industrial approval.. Excellent bottom edge run-out. Establishment of high precision below 5 m which no one can duplicate. (In case of mounting RNM type insert). Realization of high precision machining. Superior surface quality and minimum deflection are better than those of competitors. 5. Insert locates accurately in any of the two radial positions it is entered into the body. Unlike some competitors products. Multi function Inserts can be used in MIRROR BALL bodies, in case of finishing application of cutting stock below Dc/0. 0
