materials & tools The perfect tool for every application The cut-off wheel range for professional users, for fast, thin cuts with minimized burr formation, optimum tool life and efficiency with unrivalled cutting convenience. Whether cutting metal, profiles and solid material or cutting out holes, the PFERD range offers thin cut-off wheels in many different types and therefore the perfect tool solution for every application – they are efficient, ergonomically optimized and designed to the highest level of safety. The thin cut-off wheels from PFERD are characterized by their special abrasive grain and bond formulation. Intensive research, development and targeted implementation in state-of-the-art production facilities guarantee PFERD’s premium performance and safety standards. advantages: « thin cuts with minimized burr formation « maximum efficiency thanks to fast cutting and maximum tool life « convenient and safe PFERD offers three performance lines of cut-off wheels: ¤ Universal Line PSF: the entry-level range Universal Line PSF includes robust tools for processing the most common materials. Universal Line PSF tools achieve good results with high efficiency. ¤ Performance Line SG: the broad range Performance Line SG offers a high-performance tool solution for every application and every material. Performance Line SG tools achieve optimum results with maximum efficiency. ¤ Special Line SGP: Special Line SGP tools are specially developed for specific tasks and offer the user key advantages over conventional products. Furthermore, the Special Line SGP includes tools that offer ultimate efficiency thanks to their particularly high performance during use. All PFERD tools are developed, manufactured and tested in accordance with the strictest quality requirements. As a founding member of the Organization for the Safety of Abrasives (oSa), PFERD has committed to conform to tougher inspection requirements that even go beyond EN 12413 and EN 13743. PFERD quality management is certified according to ISO 9001. PFERDVALUE: PFERDERGONOMICS recommends thin cut-off wheels to sustainably reduce the vibration, noise and dust development that occurs during use and to improve comfort when working. PFERDEFFICIENCY recommends using thin cut-off wheels to achieve perfect results in no time. further information: www.pferd.com 14 no. 2, April 2021

Medical technology day “Full immersion” into the world of chip removal machining materials & tools Last September, a medical day took place at Mikron Tool’s Technology Center – of course under strict compliance with the safety regulations that were still in force. A “full immersion” day into the MedTech world, jointly orga - nized by DMG MORI and Mikron Tool. The presentations focused on the machining of medical components made of titanium and stainless steel, realized with Mikron Tool cutting tools on various high-performance machines from DMG MORI in 1 /3 of the time normally required for machining such workpieces. Near the action, not on the sidelines: from theory to practice on the machine it’s only few minutes at the TechCenter. This made it easy for the experts to demonstrate live the machining of medical components using concrete examples and explain the advantages of the tools and machines used. For example, the hemostatic clamp made of martensitic stainless steel (17-4 PH), which was completely machined in a single clamping in only 35 min on a DMU 60 eVo, known for its high dynamics and its extreme solid and stable structure. The result with CrazyMill Cool tools and the 5-axis high performance machine guaranteed high precision and excellent surface quality. We continued with deep hole drilling using the “mad” CrazyDrill Flex, in which cooling plays an essential role. The participants could witness how the tool drilled in stainless steel and titanium up to a depth of 50 x d, starting from a diameter of 0.3 mm. The results impressed all partici - pants, as they showed that it is possible to create the smallest holes up to ten times faster than with spark erosion methods or single-flute drills. Customers are already using this tool today, for example to machine phaco tips. Or CrazyDrill Cool SST- Inox, which achieves a depth of up to 40 x d in a single step and without chip evacuation, all this from Ø 1 mm and with high performance in terms of tool life and machining time. Thanks to these capabilities it is used, for example, machining of nailing systems. No time to rest, because the next presentation followed immediately, with the machining of a bone screw made of titanium grade 5 in only 3 min on a compact, flexible Sprint 32/8 from DMG MORI. The focus was on the creation of the Torx ® shape with the CrazyTool Hexalobe machining concept. This enables a turnkey solution with a 50 % shorter machining time, while guaranteeing the highest profile accuracy, excellent surface quality and nearly burr free results. The striking conclusion of the event was a bone plate (Volar Distal Radius Plate) made of grade 2 titanium, milled from the solid in only 26 min on a dynamic 5-axis machine (DMU 70) designed amongst other for the medical component industries and with a CrazyMill Cool. All this resulting in an outstanding surface quality of Ra 0.4 (grinding quality). The users benefit is a reduction of machining time from the original 128 min to 42 min (time saving 86 min per piece). The icing on the cake: at the end of the event the guests received information on the new, interesting services offered by Mikron Tool’s Technology Center. It offers customers active support from tool testing through to the development of complete chip removal machining projects. Thus, he can free up capacities and concentrate on large series production output. further information: www.mikrontool.com no. 2, April 2021 15
