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.

Mapal expands in Poland

Mapal Narzędzia Precyzyjne (Mapal precision tools) in Poland has a new head office, havingacquired 5000 sq m premises in Komorniki, not far from the previous site in Poznań. The new site has modern office spaces, conference rooms and social areas, its own logistics and storage areas,and a well-equipped showroom for customers. Mapal has invested around €2m in the facility.The company employs 72 people in Poland, including 31 engineers.

Dr Jochen Kress, president of the Mapal Group, says: “Our business in Poland has developed brilliantly over the past 25 years. Demand for our products has steadily increased and it makes us proud that we’re taking on a leading role as a tool supplier and service provider in Poland, especially in the area of tool management. Of course, we also owe this to our competent team on site, which takes excellent care of our customers and ensures the smooth running of the manufacturing processes.”

Actuating tool with four inserts for stator bores

Actuating tools are the means of choice for creating turning geometries on machining centres. When it comes to machining stator bores on electric motors, tools with indexable inserts and fine boring tools were state-of-the-art until now. Mapal has developed a complex four-blade actuating tool to round off its solution portfolio for stator drilling.

With its solution, Mapal has come up with a highly productive machining process for the series production of stator housings used in electric motors. The solution offers productivity and precision as well as short cycle times with a process of three steps: pre-machining, semi-finishing and fine machining at machining diameters of more than 220 mm and with an HSK100 connection. A sophisticated actuating tool is part of the solution.

“With an actuating tool, the internal machining of the bore can be handled by a machining centre, which means turning is no longer necessary,” says Oliver Müller, customer service specialist at Mapal’s centre of competence for actuating tools. The entire machining process is thus executable with a single set-up. The only thing needed to use the actuating tool is a spindle with a drawbar – a so-called Uaxis in the machining centre.

“When it came to machining parts for electric cars, we were at our customers’ side with our tools from the very beginning,” says Müller.“Today, we help them to increase flexibility while machining the parts reliably and with short cycle times.” The actuating tool achieves more flexibility by ensuring both fast machining of varying contour trains in the bore and micron-level precision.
