Emuge's Circle Segment End Mills Shorten Five-Axis Cycle Times
IMTS Spark: Emuge’s circle segment cutters are designed to remove more material in fewer passes during five-axis machining
Emuge’s circle segment cutters are designed to remove more material in fewer passes during five-axis machining, resulting in cycle time reductions and smoother surface finish. Said to be ideal for machining turbine blades, impellers, blisks and in moldmaking applications, the tools feature large radii in the cutting area, allowing for a larger axial depth of cut during pre-finishing and finishing operations.
The end mills are available in four geometries: barrel-shaped, oval-form, taper-form and lens-shaped. Oval- and taper-form mills are effective when machining curved shapes such as blades or straight-walled pockets, freely engaging more of the cutting edge. Barrel-shaped mills enable flank milling to the sides of spiral grooves and similar applications, while lens-shaped mills are said to excel in narrow channels or in lands on molds.
CAM system software is required to support and compute the geometries of the circle segment end mills to achieve the performance levels the tools were designed for, according to the company.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
