South Korea – With the increasing popularity of small machining centers, TaeguTec has now launched a single-sided, positive seven-corner insert line with helical cutting edges, Chase-Hepta, that generates low cutting force and achieves smooth machining, the company says.
The insert’s thickness provides better resistance to shock and breakage - an improvement over the single-sided positive inserts.
The new line is available in two geometries; M type for steel and cast iron and ML for stainless steel and difficult-to-cut materials. The line’s cutters have a 45° degree entering angle, a 3.2 mm depth of cut and an 18° axial rake angle which lowers the cutting forces during machining.
Also, the cutters acute angle pocket is good for rigid clamping and the cutters have an interference-free structure for side cutting or helical ramping. They are available in end-mills (D32-50 mm) and as face mill types (D32-125 mm) for face milling, ramping and profiling, making it a multipurpose tool.
