Milling Cutters

Tungaloy is expanding its TFE series, a long-running range of facemilling cutters for finishing applications, to incorporate bodies with insert adjustable pockets, achieving near zero axial runout for superior surface finishing results.

Seco Tools has introduced a cutting tool product line specifically designed for machining medical knee implants. The new Jabro medical range of solid-carbide cutters are suitable for high-speed machining and other aggressive milling strategies that can shorten knee implant cycle times by as much as 50 percent.

Seco Tools offers Secomax CS300 ceramic inserts and cutter bodies to boost productivity in milling and turning operations with heavy interrupted cuts on nickel-based heat-resistant superalloys (HRSA). The new cutters increase productivity by up to eight times over standard carbide milling and are ideal for machining a range of components for aerospace and power generation turbine segments, according to the company.

Inovatools provides a stable powerful package in the form of the high-end-HPC aluminum roughing endmill called "Primus". Thanks to its unique design features, such as the special entwined tooth system and the optimized microgeometry, it has what it takes to rise into the ranks of the "best in the class" when it comes to aluminum roughing, according to the company.

The CrazyMill Cool products have been developed by the Swiss tool manufacturer Mikron Tool for milling in small dimensions with high performance and quality. Now a new "family member" has been added. It is a four-teeth finishing milling cutter with shank integrated cooling, available in the diameter range of 1 to 8 mm und for milling depths of up to 5 diameters deep.

Seco Tools has introduced its R217/220.28 cutters with new body designs that incorporate double-sided round inserts to deliver cost-effective performance, as well as boost productivity. Double-negative-positioning pocket seats of the R217/R220.28 cutters deliver enhanced cutting capability and significant gains in productivity, according to the company.

It started in 2015, when engineers at a major U.S.-based aircraft manufacturer kicked-off a challenge to determine which cutting tool manufacturer offers the best products for milling forged Ti-6Al-4V titanium. The company invited Kennametal and 10 other global tooling suppliers to the University of Sheffield's Advanced Manufacturing Research Centre (AMRC) in the U.K., where the different teams competed in the challenge.

Iron's everywhere. The turbines in those big windmills popping up all over the place. Engine blocks, transmission cases, and turbocharger housings. The pumps that bring water to our faucets and the hydraulic manifolds that put the "move" into earthmoving machinery. Without iron, none of these would be possible. This is why Kennametal has produced cutting tools that make iron machining both cost-effective, efficient, and ensures easy handling.

A new, electric portable pipe machining tool that is a powerful alternative to pneumatic tools for end prepping boiler tubes and other pipe fabrication work has been introduced by Esco Tool. The ESCO MILLHOG Mini Electric Pipe Beveling Tool rigidly mounts to the tube or pipe ID and is suitable for end prepping heavy-wall stainless steel pipe and other highly alloyed metals when compressed air is not available.

The new MD133 Supreme milling cutter from Walter, designed specifically for dynamic milling, delivers increased process reliability, particularly during unmanned operation. It reportedly boosts productivity thanks to a higher metal-removal rate and a reduction in machining time.

DUO-LOCK from Kennametal Inc. is a modular endmill with the performance of solid carbide. It uses a proprietary, double-cone locating surface similar to that of Kennametal's KM or KM4X tooling design, assuring "not to exceed" radial runout values of 5 μm (.0002 in.) and Z-axis coupling repeatability of 10 μm (.0004 in.) or better.

Customers have been asking for a new carbide grade to machine titanium 6Al4V at higher cutting speeds compared to increasing feed rates or increasing depth of cuts in that result in increased cutting forces imposed on the workpiece, fixtures and machine spindles. The KCSM40 grade has an advance cobalt binder that provides thermal fatigue resistance without sacrificing the toughness customers have experienced with KC725M or X500.
