cover story Face grooving and boring are carried out with the Supermini system A successful collaboration: Peter Schockaert in conversation with Kees van Bers and Johan Willems the cutting pressure is too high”, says Willems. After axial grooving with a Supermini type 105, another Supermini of the same type is used to bore the pre-drilled hole up to the narrowly tolerated final dimension. Mini system in use Schockaert and Willems rely on special twinspindle lathes that process two seals simultaneously to achieve high throughput. The spindles are mounted above the tools and the bar feeder for the raw material, which is loaded from above, is in line with a tool carrier. The turning process does not require any tool Parker… …is a world-leading manufacturer in drive and control technology. The company develops and designs systems and precision solutions for mobile and industrial applications as well as for the aerospace sector. Almost everything that moves today incorporates Parker technology. To meet the needs of customers, Parker delivers the most comprehensive product range available from a single supplier in the field of motion and control technology. This is supported by expertise in hydraulics, pneumatics, electromechanics, filtration, process control, connectivity, refrigeration and air conditioning, sealing, EMI shielding and aerospace. Parker’s products and technologies combine components and systems tailored specifically to customer requirements. Tools are mounted in line on a platen for each machining operation (all photox by HORN/Sauermann) changes. The tools are permanently mounted in line under the spindles. During the process, the spindles move to each tool in turn until all machining operations have been completed. The Mini system is used alongside Supermini tools. “The Mini system can be adapted very well to the respective machining operations”, says HORN technician Kees van Bers. A tool is mounted on the platen for each operation. “With the large quantities involved, a very short cycle time was important to us. The tools allow us to carry out external copy turning, external grooving, face grooving on both sides, boring and parting off”, explains Willems. Parker has been working with tool solutions from HORN for about 10 years. Around 90 % of the tools used are special solutions designed specifically for the respective processes. “We are pleased to have HORN as a tool partner that fulfils our wishes and requirements precisely in terms of cutting-edge design”, says Willems. further information: www.horn-group.com 8 no. 2, May 2025
The new all-rounder for steel machining materials & tools Steel is omnipresent in industrial production and demands top performance from tools and coatings. With the latest HiPIMS coating material MultiCon®, CemeCon offers a high-performance solution especially for milling and drilling cast iron and steels between 30 and 50 HRC – for both wet and dry machining. “This is where HiPIMS technology comes into play: it produces extremely smooth, dense and homogeneous coatings with high adhesion. This opens up new potential in steel machining. The new HiPIMS coating material MultiCon® is the logical evolution of our AlCrN sputter coatings – with clear advantages in terms of performance and tool life, especially compared to arc variants”, says Manfred Weigand, product manager Round Tools at CemeCon. Tailor-made for steels from 30 to 50 HRC With MultiCon®, CemeCon closes the gap between the HiPIMS coating materials FerroCon® and InoxaCon®. While FerroCon® is ideal for soft steels and InoxaCon® for the upper range of medium steels and stainless steels, MultiCon® was developed for steels with a hardness between 30 and 50 HRC. Performance enhancements convincing Practical examples from steel processing show how MultiCon® increases productivity. When milling tempered steel (1,400 N/mm²) with a solid carbide milling cutter, tool life increases of approx. 30 % were achieved compared to an AlCrN coating deposited using arc technology. Manfred Weigand: “And that’s not all: some users even report tool life improvements of 50 to 80 %.” Practical examples show how MultiCon® increases productivity; when milling heat-treated steel (1,400 N/mm²), the tool life was increased by almost 30 % compared to an AlCrN coating deposited using arc technology With the latest HiPIMS MultiCon® coating material, CemeCon offers a high-performance solution specifically for milling and drilling cast iron and steels between 30 and 50 HRC These outstanding results are made possible thanks to the combination of optimally matched tool geometry and adapted HiPIMS coating, which is developed in close cooperation between CemeCon and the respective tool manufacturer. This allows MultiCon® to develop its full potential. MultiCon ® sets new standards “MultiCon® is the ideal solution for companies that require maximum process stability in steel machining. The coating combines the properties of AlCrN coatings with the advantages of HiPIMS technology and raises the performance of milling and drilling tools to a new level. With MultiCon®, CemeCon offers a future-proof solution that meets the requirements of modern manufacturing”, summarizes Manfred Weigand. MultiCon ® at a glance: AlCrN-based coating material HiPIMS coating technology for milling and drilling cast iron and steels between 30 and 50 HRC for wet and dry machining optimum wear behavior, excellent adhesion, extremely smooth maximum operating temperature of 1,100 °C dark grey color available in 3 µm coating thickness for round tools further information: www.cemecon.de no. 2, May 2025 9
