Tooling systems specialist Sandvik Coromant has developed a new tangential milling cutter. The M5Q90 is designed to complete ‘cubing’ (the first machining of faces after casting) in a single operation without creating burrs. The tool is reportedly fitted with PCD tangential inserts that offer a smoother and more stable cutting action and eliminate vibration.
M5Q90 cutter bodies are designed according to user specifications and can operate in high-speed conditions in excess of 20,000 rpm. All cutter bodies have the same design of tip seat, coolant channel, lead angle and rake angle. If desired, the cutter body tool life can be further extended in engineered solutions with PCD inserts protected by rows of carbide inserts, a configuration that also serves to increase the depth of cut capability. While the basic tool with PCD inserts offers 2-4 mm (0.079-0.157 inch) depth of cut in full engagement, this can be increased to in excess of 4 mm (0.157 inch) using the engineered solution with protective rows of carbide inserts.
The tool is suitable for machining aluminum cylinder heads and engine blocks at automotive foundries or for Tier 1/Tier 2 suppliers. The cubing operation on a cast cylinder head would involve machining the camshaft face, inlet/outlet face and combustion face. Typical cutting data using M5Q90 might include a speed of 2500 m/min (8202 ft/min) and feed per teeth of 0.20 mm (0.008 inch). The M5Q90 is capable of both face and shoulder milling and is also suitable for applications in the general engineering and aerospace sectors.
