Challenge: Raise versatility, reduce the cost solution of small lot milling: Use milling cutter of general nicety square shoulder, raising manufacturing efficiency to control cost CoroMill 490 is a kind of brand-new milling cutter, reflected the essence of milling art, it is establishing new standard for mill of knead dough of square shoulder mill. Square shoulder mill occupies the half above that world milling applies. As mechanic workshop preparation adopts each to aim to increase manufacturing efficiency and the significant change that reduce cost, this domain is sure to grow quickly. Machine job shops has become increasingly compact, and can get used to specific need better. Square shoulder mill is reviving breathtakingly in experience, a reason is, manufacturing engineer is choosing gradually to realize new treatment requirement with Bench Machine Tool. So, do square shoulder mill and Bench Machine Tool have He Lian to fasten? Because be close to the high grade cast of final measure and forging to get more and more use, this means the precision work that reduces a hardware, and the finish machining that reduces a hardware, need to use the milling cutter with the cutting tool with cutting more shallow deepness and lesser diameter. This kind of lesser cutting tool is square shoulder milling cutter commonly, requirement use main shaft is 30 with the Bench Machine Tool of 40. Finally, bench Machine Tool takes up in the workshop the space is little, thereby can bring down capital and operation cost. Be in as production lot a lot of medium or small mechanic workshop decreases ceaselessly, the client does not wish to maintain many of all kinds cutting tool, among them some of cutting tool is used rarely, or use very short time only. Contrarily, these companies ask cutting tool sort is little, but versatility is strong, so that reduce cutting tool inventory, reduce reserve demand, increase the flexibility of the machine tool. The square shoulder milling cutter that new fine designs is in ceaseless emerge in large numbers, the CoroMill 490 that makes meticulously for example has the halcyon, characteristic such as nicety and crackajack versatility. The radial cutting force that a feature of CoroMill 490 is bit is very small, this is by outstanding bit chamfer brought result, this is a very main good point, when force of exorbitant and radial cutting exists in square shoulder mill, can avoid the appearance of workpiece of cutting tool deviate. Exorbitant cutting force can reduce the quality of the spare parts, the appearance that causes difference is bright and clean spent vibration, want inevitably to reduce cutting parameter thereby. Conclusion: Milling workshop service mass is taller and the cast of adjacent and final measure and forging. This is meant reduce finish machining, ask to use high accuracy cutting tool -- typical is the milling cutter with the humeral milling cutter with cutting more shallow deepness and lesser diameter. They suit to be used at Bench Machine Tool very much, and Bench Machine Tool conduces to economic cover an area of a space, reduce capital and operation cost thereby. Of production lot decrease to ask to use fewer but more general cutting tool. This kind of versatility can reduce the need of inventory and keep in storage again, increase the flexibility of mechanic workshop. The development of CoroMill 490 is to satisfy these requirements.
