The seven grades: ACP100, 200 and 300; ACK200 and 300; and ACM 200 and 300, can cut to depths of up to 5 mm. ACP100 has the latest Sumitomo ‘FF’ CVD coating, giving wear and thermal resistance in the high speed and light cutting of steel. Sumitomo’s ACP200 uses the company’s ‘Super ZX’ PVD coating on a carbide substrate, which is said to enable milling 1.5 times faster than conventional inserts. ACP300 also has Super ZX coating and is designed for use under more arduous roughing applications.
ACK200 with its ‘Super FF’ CVD coating is for use in general machining tasks (including interrupted cuts) involving grey and ductile cast irons. ACK300, which is coated with Super ZX, provides a solution able to generate even greater levels of productivity.
Sumitomo’s ACM200 is coated with Super FF to provide high orders of wear resistance when machining PH stainless steels, while ACM300 is first choice (with its Super ZX coating) when a balance between wear and fracture resistance is required.
AXMT inserts can be paired with Sumitomo’s new WEX Type 1000 cutter bodies for 90° shoulder milling applications. In fact, pocketing, helical boring, slotting, shoulder milling and ramping cycles can be carried out with the same tool, says the company.
Three tool body designs incorporate short type ‘E’ and ‘EL’ variants, as well as shell type ‘F’, which uses a smaller Sumitomo AXMT06 insert featuring a high rake ‘wave style’ cutting edge. All body variants support enhanced chip evacuation through internal coolant feed. Short type E is available from 10 to 25 mm diameter and has between two and seven insert pockets. Short type EL in diameters between 10 and 20 mm has between two and four teeth, while shell type F offers outside diameters between 32 mm (with eight teeth) and 63 mm (with 14 teeth).
