Circle-Segment End Mills Enable Faster Machining Cycles and Smoother Finishes

Emuge Corp. “circle-segment” cutters, are a class of end mills designed to enable substantially more material removal with fewer passes in five-axis machining. The company says they also reduce cycle times by more than 80 percent and produce up to 50 percent smoother surface finishes.

Emuge says these cutters are ideal for mold making applications. They feature unique forms with large radii in the cutting area of the mills, allowing a larger axial depth of cut during pre-finishing and finishing operations.

Circle-segment solid-carbide end mills are offered standard in four geometries: barrel-shaped, oval form, taper form and lens shape. Oval and taper form mills are ideal for curved shapes such as straight-walled pockets, freely engaging more of the cutting edge. Barrel design mills provide highly effective flank milling to the sides of spiral grooves and similar applications, while lens shape mills excel in narrow channels or in lands on molds.
