To address the issue of requiring multiple, dedicated cutters in the toolchanger of a machining centre to create different component chamfers, Sandvik Coromant can now offer CoroMill 495®, a universal tool which ensures machine shops only require a single chamfer cutter to perform various chamfering operations. This not only creates extra space in the toolchanger but minimises tool inventory and costs.
Most engineering components require at least one chamfer, and because the majority of modern machine shops run small batches in many different materials, the potential for excessive toolchanging and extended set-up times is vast. With CoroMill 495, the same tool can undertake a wide variety of chamfering operations, reducing downtime and maximizing machine utilization. The tool features indexable inserts with four cutting edges, and cutter bodies with a high number of inserts in relation to body size.
Many operations… As well as conventional topside chamfers, CoroMill 495 can be used to pass through a bore and chamfer the underside of components. This versatile cutter can also be used to perform weld preparations, deburring operations and even face milling if required. Available cutter diameters include 12-25 mm and 40-63 mm to create 15°, 30°, 45° and 60° chamfer angles using coupling types such as cylindrical shank, Coromant EH and Coromant Capto®, while a 0.5-1” imperial version takes advantage of a Weldon coupling. Both GC1030 (-PM geometry) and GC1040 (-MM geometry) grades are available to ensure successful chamfering in a multitude of different materials, including steel, stainless steel, cast iron, aluminium and heat resistant super alloys.
