It's available with a HSK-A100 20K spindle that offers 50/55 kW power for everything from heavy-duty cutting to fine precision work on aluminum alloys, cast irons and difficult to machine materials. The HMC allows for steady milling, boring, drilling and tapping of mass production parts to long, continuous cycles for die/mold applications. High efficiency is easily achieved with improved chip flushing and conveyance that keep chips flowing. The work envelope is one of the largest in its class and provides the flexibility to handle a range of workpieces. Flexible manu- facturing can be accomplished by adding 6 to 12 multi-pallet APC units and multiple matrix magazines that hold as many as 400 tools. The ATC features a two-second tool change time and comes equipped with tool breakage detection. A left mounted operation panel that has a rotating mov- able monitor improves operator visibility and a wide, two-step platform makes the spindle and workpiece easily accessible, increasing shopfloor productivity, the company says. The MA-600HII is constructed on a 58,000-pound frame featuring an integral bed and base with a highly rigid, stepped back column that withstands bending and torsion to easily sup- port rapid travel of large, heavy parts. :: Okuma America Corp. 704-588-7000, okuma.com Insert Overcomes Challenging Machining Conditions Machine shops faced with identifying ways of achieving secure ma- chining with long and predictable insert life in steel milling opera- tions can turn to GC1130. The insert helps to overcome challeng- ing machining conditions with a clean and intact edge, designed to deliver high metal removal rates and performance levels in both wet and dry machining operations. The grade is offered as the first choice for shoulder milling cutters—CoroMill 390 and CoroMill 490 and chamfer cutter, CoroMill 495. Flaking, abrupt chipping and thermal cracks are common issues encountered when milling materials in steel applications, especially when faced with unfavorable tool paths and deep cavities or when using coolant. GC1130 has been specifically developed to help production engineers combat the subsequent unwanted effects of short insert tool life and unstable production. Manufactured with Zertivo, a technology that helps amplify the grade's benefits offers better edge-line security and reduced flaking. A high Cr content fine-grain substrate delivers high resistance to thermal cracks generated because of temperature fluctuations during machining, helping to ensure long and reliable tool life, the company says. :: Sandvik Coromant Inc. 201-794-5000, sandvik.coromant.com PRODUCTS 44 PRODUCTION MACHINING :: JUNE 2017
