With its proven "Engineering Kompetenz", which means its capacity to provide technical machining solutions, Walter is uniquely positioned to grow.

Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.

Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.

As an expert in the automotive component industry, Zhang joined Walter in 2022 to prepare the company's Chinese subsidiary for the future.

The NEV industry is one of the fastest developing industries in China. In 2023, China's NEV production reached a record 9.58 million units. Along with the advancement of technology and infrastructure, experts believe the new energy market will continue to grow. With this, the demand for aluminum alloy components will also rise — a beneficial trend for Walter as a leading tools specialist in nonferrous materials.

New Beyond KCPM20 inserts are available in a variety of Kennametal milling cutter styles, including:

Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

New energy vehicles and lightweight materials manufacturing, especially aluminum alloys, are two examples. Being particularly fast-paced, the Chinese market for machining tools and solutions requires an agile organization and mindset to actively respond to customer demand.

Founded more than 100 years ago as a one-man-engineering shop for researching sintered carbide alloys and new metallurgical processes, Walter, from the south of Germany, quickly developed into a full-scale company for brazed carbide milling tools.

Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.

Kennametal is introducing the new BeyondTM KCPM20 grade indexable milling insert, specially engineered for high-speed dry machining in light to medium milling of steel and stainless steel parts under stable conditions. KCPM20 is being recommended as an ideal optimization grade for stainless steel machining applications where coolant is not used and excellent wear resistance is required.

German-based Walter, one of the leading specialists for machining solutions for metalworking industries, realized the potential of the Chinese market more than 30 years ago. Today, the Walter Chinese subsidiary has more than 270 employees in 50 cities and sees itself well prepared for the future.

Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

Additionally, all Beyond inserts are top- and bottom-ground after coating for a better seating surface in the toolholder, which improves security.

Chinese companies have developed into a major global technological driving force for industries including new energy infrastructure, automotive and general machinery. With a strong and extensive manufacturing base, China has also become one of the most significant and dynamic markets for metal cutting tools in the world.

All new Beyond inserts are CVD (chemical vapor deposition) coated, but whereas conventional CVD coatings are under tensile stress, Beyond inserts undergo a proprietary post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping. More uniform and reliable wear of the cutting edge results in improved and more consistent tool life. Smoother surfaces also lower frictional forces, another factor that expands applications and permits higher cutting speeds.

Zhang Zhijun, president of Walter China and board chairman of Walter Wuxi, said: "The Chinese government is rolling out some stimulus policies, and I remain cautiously optimistic about the market in the coming years."

Besides management and administration, the headquarters in Wuxi also hosts a production unit with 70 employees. Standard indexable inserts and tool bodies are manufactured there.

Among its workforce in China, Walter has around 110 sales engineers to constantly provide direct and quick contact with customers across the country.

Each specific Beyond grade from Kennametal is optimized with substrate characteristics and coating thickness specific to its application. The result is productivity improvement and an expanded range of application for each new product compared to the original grade.

The development has led Walter to further invest considerable sales and technical resources into existing partnerships with high-profile clients.

Loosely, any milling tool. Horizontal cutters take the form of plain milling cutters, plain spiral-tooth cutters, helical cutters, side-milling cutters, staggered-tooth side-milling cutters, facemilling cutters, angular cutters, double-angle cutters, convex and concave form-milling cutters, straddle-sprocket cutters, spur-gear cutters, corner-rounding cutters and slitting saws. Vertical cutters use shank-mounted cutting tools, including endmills, T-slot cutters, Woodruff keyseat cutters and dovetail cutters; these may also be used on horizontal mills. See milling.

For Walter, China is a strategically important market, not only in sales but also in keeping on top of manufacturing and technology developments that will shape the future of major industries worldwide.

The company now serves customers from various industries in more than 80 countries with 3,800 employees worldwide.

"While optimized for steels and stainless steels, KCPM20 also can act as a troubleshooter in cast iron applications, particularly with nodular irons in dry conditions," says Osny Fabricio, Kennametal Senior Product Manager. "Use KCPM20 when existing applications need to be optimized to gain additional tool life and productivity via higher speeds and feeds."

He said: "We are currently working hard to meet our customers' needs while consolidating and amplifying our 'Engineering Kompetenz'. Additionally, we are actively developing new business opportunities to be well prepared for future developments in the market."

Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

In China, the company has been part of the thriving industrial sector since 1993 when it opened its first Chinese site in Wuxi, Jiangsu province: Walter Wuxi Co. The Walter China facility now manufactures solid carbide drills and end mills for the global market, boasting a wide spectrum of high precision computer-controlled machines.
