Milling

Kennametal is expanding its Mill 4 family with a new cutting tool, the Mill 4-11. Designed for smaller machining centers, the Mill 4-11 accommodates 40-taper CAT and BT, HSK 50 and similarly-sized spindles. Due to its free-cutting capabilities, it is ideal for successful metal removal in less-than-rigid setups and on light-duty machine tools, multitaskers and live-tool lathes.

Chris Merlin, director of portfolio commercialization for the WIDIA Products Group, visited with Cutting Tool Engineering Publisher Don Nelson during IMTS 2016 to discuss the company's 90-year milestone and latest technology, including the VariMill Modular System, the VariTap and the features of the NOVO app.

The new MC341 Supreme carbide shoulder/slot milling cutter from Walter is specially designed for extended tool life when machining steel and stainless steels. According to the company, yhe cutter delivers exceptional tool life, plus performance improvements of up to 100 percent thanks to the innovative new Walter WK40TZ grade, a special proprietary coating process and added design enhancements as well.

Makino announces the latest addition to its next-generation series of horizontal machining centers, the a71nx. This horizontal machine platform extends the capabilities of the original a71 with a host of brand-new features and technologies, including an expanded work envelope, improved ergonomics, increased spindle torque, innovative tool monitoring, advanced motion controls and the new Professional 6 control.

Back in 2014, Kennametal announced a technology partnership with Haimer for the development of a modular cutting tooling system. Since that time, the company has been busy developing, testing, and building inventory of DUO-LOCK, which promised even then to be "the most rigid and most precise interface in the marketplace."nToday it's even better.

C.R.Onsrud introduces a hybrid of traditional milling technology with the productivity of high-speed machining. This American-made 5-axis machining center is configured with dual tables eliminating load unload time. It also has the capability to electronically lock the two tables together for machining of large parts.

Sandvik Hyperion's BZN V-Series PCBN grades provide versatility in three key aspects of machining of hardened ferrous materials. First, the grades are able to work in case hardened, bearing steels, powder metal alloy steels, and tool steels.

Sandvik Hyperion's carbide grade AM70 is an advanced substrate developed to increase machining productivity and performance in titanium and ISO M materials. The AM70 grade is comprised of a combination of submicron carbide grains that provide the perfect mix of toughness and wear resistance.

MK Tools solid-carbide round tools from Monaghan Tooling Group introduces new "Speed-Drill R4" geometry, reportedly offering unparalleled cutting speeds and unprecedented tool life when cutting gray cast iron, ductile iron and forged steel, which are popular materials in automotive engine and chassis components.

Kern Precision says its Micro 5-axis milling machine does not only tout its reliability and precision, but also the size of its footprint, the capacity of its palletized toolchanger, its plug-and-play capability, its power and its versatility in terms of the size of workpiece it can accommodate.

Walter says it has unveiled a technology that promises to dramatically improve machining effectiveness. Called Tiger·tec Gold, it is the latest iteration of Walter's successful line of Tiger·tec and Tiger·tec Silver coatings.
