Circle-segment end mills


West Boylston, Massachusetts – Emuge Corp. has introduced circle-segment cutters, an innovative class of end mills designed to enable substantially more material removal with fewer passes in 5-axis machining, more than 80% cycle time reductions and up to 50% smoother surface finishes. Circle-segment tools are a totally new end mill design, exclusive to Emuge.

These high-performance tools for machining turbine blades, impellers, blisks, and in mold making applications, feature large radii in the cutting area of the mills, allowing a larger axial depth of cut during pre-finishing and finishing operations. 

Emuge circle-segment solid-carbide end mills are offered in four geometries: barrel-shaped, oval form, taper form, and lens shape. Oval and taper form mills are for curved shapes such as blades or 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. 

Specific CAM system software, such as HyperMill (Open Mind) or Mastercam Version 2017 (CNC Software Inc.), is required to support and compute the geometries of Emuge circle-segment end mills to achieve the performance levels for which the tools were designed.

“Our all-new circle-segment end mills, only available from Emuge, provide unprecedented levels of machining performance in complex 5-axis applications, allowing precision manufacturers to attain dramatic time and cost savings, while increasing part quality,” said Bob Hellinger, president of Emuge Corp.

Emuge circle-segment end mills are offered standard, and are in stock at Emuge Corp. North American headquarters.
