1 TOOLS NEWS Exchangeable Head End Mills imx End Mill Series Update B2G Application expansion World first!* Carbide + Carbide (head) Double face contact type (holder) * According to our own research on exchangeable head end mills.

2 Exchangeable Head End Mills imx End Mill Series Special steel screw joint Available with internal coolant Point Double face contact type (Ter + End face) Point Mono-block carbide holder Cemented carbide Steel Steel Cemented carbide The imx series is a revolutionary end mill system that enables efficiency, high accuracy and rigidity by combining the advantages of both solid carbide and indexable end mills. Security and rigidity close to that of a solid type end mill because the clamping faces are all carbide. Excellent for reduced inventory over a variety of plications due to the exchangeable head. 1

3 Highly versatile grades EP72 Smoothed surface "ZERO-μ Surface" Newly developed(al, Cr)N group coating Super-fine particle, super-hard base material EP72 Suitable for difficult-to-cut materials. EP612 Suitable for high feed milling of steel. ET22 (Uncoated) Suitable for milling aluminium. Tool life comparison when machining flat surfaces in Inconel 718 EP72 is a new grade that enables extended tool life when machining diffi cult-to-cut materials. Max.

4 Exchangeable Head End Mills imx New lineup Corner radius, Ter head, Multi-flute, with coolant hole Ter radius end mills(torus cutter) were conventionally used for turbine blade fi nishing. imx ter radius offers the performance equivalent to solid end mills and it can achieve lower milling cost. Features Extensive size lineup of corner radius For a wide range of plications Ultra multi flute Higher efficiency milling by multi-flute design more than conventional. Ter angle on side = 8 Coolant through hole For more sable chip evacuation Drastically reduces cutting time Possible to process using a large pick feed (pf) when the cusp height is shortened and fi xed even using the same pf. pf Cusp Height pf Cusp Height 3 Set pf = 2.mm, with R5 of the ball nose end mill Set pf = 2.mm, with IMX1C8T8R1T8C

30 INDEXABLE HEAD END MILLS HOW TO INSTALL THE HEAD 1 Using a clean cloth, wipe away oil and dust from the ter and end surfaces of the head and holder. Wipe off oil and dust 2 Apply a small amount of anti-seize compound to only the screw head part Anti-seize compound (only screw part,small amount) 3 Be careful of the plication amount. If over-plied, the anti-seize compound while fastened will spread around the ter part and possibly effect the fastening mechanism. [Example of wrong plication] <Ter head part> <Ter holder part> Wipe off the anti-seize compound and make adjustments. 4 Anti-seize compound Be careful to avoid the possibility of cutting hands when fastening with bare hands directly near the blade tip. Securely fasten the head and holder end surfaces using the enclosed wrench to close off any remaining g. Clearance No clearance 5 Refer to the table at below regarding angles for recommended torque when necessary. For stricter usage, refer to the table below for torque wrench fastening. Fastening size Reference Recommended tightening angle α clamping torque (Nm) IMX1 5 1 IMX IMX IMX2 4 5 IMX α Note) Use the enclosed wrench only. (Typical wrenches differ in thickness.) 29

31 HOW TO SELECT imx HOLDERS awhen using straight holder + standard head, interference will occur in cases where the depth of cut is larger than the length of cut of the head. awhen using straight holder + offset head, larger depths of cut are possible because the diameter of the head is larger than the holder. Straight + Standard head Straight + Offset head When using straight holder + standard head, please use at smaller depth of cut than length of cut. No contact Depth of cut Depth of cut < Length of cut Length of cut Depth of cut Length of cut Less than 3D overhang is recommended when depth of cut < length of cut. aundercut type with relieved neck is suitable for vertical wall machining. athe large diameter of the ter neck holder provides stability in long overhang plications. aundercut and ter neck types are now also available. (Please refer to diameter DC of each type for minimum diameter.) Undercut + Standard head Ter neck + Standard head BHTA Interference angle No contact 3
