Renishaw celebrates 50 years of innovation

This year, Renishaw is celebrating its 50th anniversary. The company, which began trading on 4 April 1973, will mark this significant milestone with a year of global activities, including open house events at its largest sites, family days for employees and a ‘50 at 50′ charity initiative that will see £150,000 donated to 50 not-for-profit organisations in the 36 countries where it has offices.

The company was formed half a century ago to commercialise the invention of a touch-trigger probe by now executive chairman Sir David McMurtry, solving a dimensional measurement problem at Rolls-Royce when manufacturing Olympus engines for the supersonic Concorde aircraft. Today, Renishaw is listed on the FTSE 250 index with a current valuation around £3bn. The company employs 5200 employees in 36 countries, including 3400 staff at its sites in the UK, primarily in Gloucestershire and south Wales.

Turning grade features advanced coating technology

Kennametal has introduced a higher performance turning grade with an advanced coating technology. KCP25C with KENGold is now the company’s first-choice offer for metal-cutting inserts with improved wear and higher metal removal rates in steelturning applications.

“Our high performance KCP25C grade inserts with KENGold coating technology sets a new standard for machinists working across a variety of steel turning applications,” saysvice president of global product management Scott Etling. “This gold standard turning insert delivers a one-two performance punch of higher metal removal rates and improved wear resistance, meaning our customers can machine longer and with greater productivity and efficiency than before. Additionally, the insert’s gold flank makes it easy to visually identify wear, maximise edge use and reduce waste.”

According to Kennametal, KCP25C is the company’s first-choice carbide grade for turning inserts in general purpose applications in a variety of steel materials and delivers consistent, repeatable performance. KENGold is a proprietary, multi-layer coating technology with enhanced pre- and post-coat processes that deliver an effective thermal barrier for greater resistance against crater wear, which is common in these types of machining applications.

KCP25C with KENGold is an example of how Kennametal’s global modernisation investments are enabling the company to innovate higher-performing products for customers. Kennametal uses next-generation CVD technology to produce the coating while advanced pressing and surface treatment technologies deliver tighter tolerance levels than ever before, resulting in a more consistent, reliable tool life.

Kennametal is releasing KCP25C with KENGold in the most common insert shapes and styles: C, D, S, T, V and W. Longer term, the company plans to expand on KCP25C with additional turning insert shapes and styles—all featuring the KENGold coating technology.

Aluminium component milling at expert level

Walter is extending its range of solid-carbide milling cutters for ISO N machining with the addition of two distinct roughing specialists, the MD265 Supreme and the MC268 Advance. The MD265 Supreme three-edged cutter with a diameter range from 16 to 25mm is available as coated or uncoated, standing out with its coolant channels in a star-shaped configuration, as well as robust cutting edges with RAPAX profile.

It was designed to achieve high productivity and process reliability required in sectors such as automotive. Whether uncoated with polished surfaces or coated with Walter’s new WJ30DD grade, it can optimise chip removal, reduce material build-up and extend tool life. This is of particular interest for manufacturers machining die-cast aluminium with the high silicon content.

Also new to the portfolio is the 6 to 25mm diameter range MC268 Advance. Incorporating a polished innovative profile that can be used universally, it is designed for long-chipping wrought aluminium alloys that are often found in the aerospace industry, for example. The coolant outlets of the three or four-edged milling cutter feature a radial arrangement for strategies such as dynamic milling. Furthermore, it reduces tooling costs as it is suitable for reconditioning.

Both solid-carbide milling cutters aim to reduce machining times in ISO N materials and increase metal removal rate. The V-shaped cutting edge, which is typical of both milling cutters was developed in-house at Walter, which says it is the only one of its kind on the market. Grooved cutting-edge profiles split the chips into short, easily controlled segments. This effect increases process reliability and allows users to work with reduced cutting forces.
