High Feed Rate Cutting Tips
Ingersoll says the two newest solid carbide tips in its Chip-Surfer line help save machinists money by replacing only the used portion of a tool rather than the entire shank. The first of the two, the Toroidal finishing tip, features six flutes for increased feed rate. It has a constant diameter, which the company says is helpful in ballnose milling because feed rates typically approach zero at the axis of the cutter. The tip has a backdraft angle designed to alleviate side pressure and reduce the potential for chatter.
The second, the Hi-Feed Chip-Surfer tip, features a radius on the nose that directs cutting forces through the Z-axis. When applied at a 0.15"-0.40" DoC, the chip thinning design gives the tool 5x more high-feed capabilities than a standard ballnose design, the company says. A corner radius and OD backdraft angle are designed to alleviate radial pressure in the corners, while the precision simultaneous fit adaption allows +/- 0.0005" repeatability when changing tips.
