materials & tools Automatic profile changing system awarded At the end of the previous year, Leitz GmbH & Co. KG was awarded the Innovation Award of the Eastern Württemberg Chamber of Industry and Commerce – for the development of the flexTrim3 automatic profile changing system. The patented flexTrim3 system was developed specifically for quick profile changes within continuous production processes and successfully brought to market. Since its market launch about two years ago, furniture manufacturers all over the world have been producing their furniture components such as carcasses or fronts with this tool system. FlexTrim3 shows its full effect in batch size 1 production and leads to significant increases in the efficiency of the production process by elimina ting downtimes for profile changes. Since manual tool changes take a lot of time, this way of changing profiles is simply uneconomical for batch size 1 production. Alternative systems for tool changing are usually very expensive and also require a lot of installation space within the machine. The flexTrim3 profile changing system from Leitz; the name already describes what is probably the greatest advantage of the system: the combination of three different profiles in one tool makes edge processing more flexible than ever before The product of the world market leader from Oberkochen convinced and inspired the jury in particular with regard to the evaluation criteria “economic efficiency”, “originality”, “chance of realisation and use”, “effort for the idea” and “sustainability”. The “Award for Patents and Talents” is handed out every year to regional companies, persons and organisations for the development and implementation of outstanding innovative ideas. With flexTrim3, Leitz offers an economically acceptable solution for this type of challenge. The 3-in-1 concept allows automatic profile change between three different profiles. In terms of profile types, all customer-specific radius and chamfer profiles, up to a depth of 3 mm, can be implemented on the profile rims. Even the combination of “with feed and against feed” is individually possible with the system. The profile changes are programme-controlled and take just 30 seconds! The result is a maximally efficient batch size 1 production with less manpower and very short downtimes. The flexTrim3 system is also universally applicable in the materials to be machined. Softwood, hardwood, veneer or plastic laminates can be processed reliably and in top quality. On the machine side, the new flexTrim3 system can be used specifically on HOMAG FF32 units. In terms of sustainability, particular emphasis was placed on using resources as efficiently as possible. By using diamond cutting edges, the tools have very long lifetimes of one year and more before they need to be replaced. In this way, the pressure switching mechanism can be reused at the end of the tool’s lifetime. flexTrim3 provides more flexibility and efficiency in edge processing as well as an increase in productivity. A solution from Leitz showing how practice-oriented and value-added tool development works today. It proves its innovative strength and clearly underpins its position as world market leader. further information: www.leitz.org 10 no. 1, March 2022

materials & tools Machining carbide with PCD solid head milling cutters KNOW THE FEELING? With new PCD solid head milling cutters, MAPAL is extending the possibility of machining carbide and other hard-brittle materials to smaller diameters. Deep-drawing dies in the die and mould sector are often made of durable carbide. Machining them by die-sinking or grinding is tedious. Machining with coated solid carbide tools often suffers from high wear and low tool life. PCD tools are a cost-efficient alternative here. Then stop using complicated controllers for precision motion. You shouldn’t need a Ph.D. in control systems to program your controller. The new PCD solid-head milling cutters convince customers with short process times and long tool lives when machining carbide and other hard-brittle materials With Automation1, you can now reduce your set up time—in many cases, from days down to minutes—thanks to a user-friendly, intuitive interface and machine setup wizard. Automation1 is the most user-friendly precision motion control platform available. The punches and moulds usually require tools with diameters less than 6 mm. To execute these tool dimensions in PCD, full-head PCD must be used, since smaller milling cutters have no room for brazed-on cutting edges and their substructure. With new geometry, number of cutting edges and arrangement, MAPAL now makes it possible to machine hard-brittle workpiece materials with diameters from two to six mm. To produce the perfect PCD tool according to customer requirements, blanks are kept in stock in the appropriate sizes. PCD is more expensive than solid carbide, but thanks to the longer tool life and shorter process times, break-even is quickly reached. In tests, the new milling cutters managed significantly higher feeds per tooth compared to solid carbide and therefore a much higher machining volume. In addition to carbide, hard-brittle materials also include zirconia, a ceramic material used in dental technology. The new PCD solid head milling cutters from MAPAL are also an alternative to solid carbide in this area. further information: www.mapal.com Motion made easy. Visit uk.aerotech.com/automation1
