Machining

HEIDENHAIN's family of KGM grid encoders have once again been improved to better meet the needs of CNC machine users who require accuracy testing. Now the KGM 281 grid encoder is available with a measuring range of 140 mm in diameter and an increased accuracy of ±1 µm.

Heller Machine Tools introduces its versatile HF series 5-axis horizontal machining centers to North America for machining complex prismatic parts from lighter, smaller workpieces to heavier workpieces up to 800 kg table load. In the series of two machines, the fifth axis is provided by the workpiece on a swiveling trunnion with rotary table or a pallet changer for higher-volume production.

W.W. Grainger Inc.'s metalworking team put together this brief video on the benefits of high-feed milling as part of the company's Quick Tips video series, which is part of Grainger's online resource center, The Knowledge Center.

Dr. Jeffrey Badger, who writes the Ask the Grinding Doc column for Cutting Tool Engineering magazine, offers a closer look at TG grit in the 78th episode of the Grinding Doc video series.

Walter has added to its range of solid-carbide milling cutters with the introduction of its MC232 Perform product line. This versatile, cost-effective new cutter type is available with 2, 3 or 4 flutes, in a diameter range of 1/8 in. to 5/8 in. (2 to 20 mm).

Seco Tools released two new solid-carbide endmills that significantly boost metal-removal rates and offer exceptionally long tool life for a variety of today's challenging workpiece materials. The Jabro-HFM JHF181 is suitable for high-feed milling strategies in hardened steels and nickel-based alloys, while the Jabro-Solid2 JS564 and JS565 represent Seco's continued focus on developing tools for optimized roughing strategies for materials such as steels, stainless steels and titanium alloys.

Micron USA's new heavy-duty, dual-support centerless grinder offers 16" (405 mm) wheel width capabilities and twin-grip. This design improves on the company's existing designs and integrates the latest control technology.

In a blog, Dann Demazure, applications engineer at Datron Dynamics, wrote: Machinists ask me all the time, "When do I go fast and when should I go slow with a single-flute endmill?" Well, as you can imagine, there are a lot of variables at play regarding feed rates for single-flute endmills, but let's try to break it down.

SPRING Technologies announces the latest version of its flagship NCSIMUL SOLUTIONS. The new version sets a benchmark for comprehensive control of the machining process, allying ease of use, flexibility and automation to build the Factory of the Future, according to the company.

Bob Warfield of the CNCCookbook.com addresses tool life issues when micromachining in the third episode of The CNC Chef, a new video series from Cutting Tool Engineering. In this episode, Warfield takes a close look at tool runout, which he says is the No. 1 issue for tool life problems when micromachining.

With the TENDO E compact, SCHUNK says it has started a new era in tool clamping with this universal toolholder that is suitable for applications such as milling, drilling, and reaming. SCHUNK now offers new extended lengths in CAT 40 (4") and CAT 50 (6"). Both are great for long-reach applications and in multiple-axis machines.
