    The HELIALU Family Expands with Super Positive Polished Rake Inserts for Machining Aluminum and Non-Ferrous Materials


    MULTIMASTER

    Highlights
    ISCAR expands the HELIALU Inserts Line by adding a new sub-micron grade which assures higher productivity for 90˚ aluminum and non-ferrous milling (ISO N).



    Metal cutting technology has progressed over the past few years. The results shows precise, safe and stable machinery capable of perfroming highly complicated operations with increased feed rates.

    The results provide ISCAR’s customers with the ability to choose tougher and harder grades.

    Machining aluminum with a hard-wear resistance sub-micron carbide grade IC08 maintains the insert’s cutting edge sharpness for longer periods of time. This contributes greatly to stable machining and longer tool life, which enables milling aluminum at very fast feed rates, and milling aluminum-lithium alloys.



    The BUE phenomenon has a negative effect when machining aluminum.

    Low feed rates - creates negative land on the cutting edge



    High feed rates - reduces BUE

    HSM90S APCR 1405
    Super Positive Inserts with a Polished Rake for Machining Aluminum at High Rotation Speed

    • When machining at very high cutting speed and replacing the insert, it is also recommended to replace the screw
    (1) Tool's pocket should be modified by rounding its corners to R=2.5 mm
    (2) Measured on the cutter



    HM90 AXCR 1505
    Super Positive Inserts with a Polished Rake for Machining Aluminum

    • Note: It is recommended to use the insert and screw set when machining at very high cutting speed.


    HM90 APCR 1605..R-P
    Super Positive Inserts with a Polished Rake for Machining Aluminum

    • It is recommended to use the insert and screw set when machining at very high cutting speeds.
    (1) Use with HM90 ....16BR tools only.
    (2) Measured on the cutter

    Safety Recommendations
    • Insert pocket should be thoroughly cleaned prior to clamping the insert.
    • Screw clamping torque as recommended in ISCAR’s catalog data.
    • Replace the screw after each insert change.
    • Running the tools beyond maximum recommended R.P.M. values may cause insert breakage, machine damage and bodily injury.
    • As the HELIALU inserts have sharp cutting edges, always wear protective gloves to avoid injury when handling.
