In addition to automotive production, the aerospace industry has become a strong pillar for MAPAL. In the field of PCD tools, the focus is on two very different applications, namely high volume machining of large parts and bores in carbon fibre reinforced plastic (CFRP materials).

PCD tools are used as standard for machining spectacle glasses. MAPAL has developed a custom tool for a major customer in the glasses industry that significantly increases productivity. The data measured by the optician is sent directly via a remote data transmission network to the machine, which automatically mills lenses with the required optical corrections. For the process, the machine, spindle, number of cutting edges, cutting edge geometry and edge preparation were coordinated in such a way that the customer was able to produce with great accuracy and reduce the costs for each part thanks to long tool life and fast machining.

“We’re able to transfer the expertise gained in the automotive industry to other industries – even when it comes to completely different materials such as glass or plastics,” explains Leander Bolz, Sales Manager of PCD Tools at MAPAL. An advantage is the sales department’s focus on technical advice, which can also put together all-round carefree packages for the customer. As the manufacturers of high quality parts often have global production sites across various locations, it’s a plus that MAPAL also has an international positioning. “We have twelve manufacturing facilities for PCD tools worldwide that deliver the same quality everywhere, provide on-site service and also carry out repairs,” assures Carsten Lehmann.

Aluminium materials are increasingly being used in various industries. MAPAL is the leading technology partner for the machining of aluminium components.

When materials other than aluminium are machined and new parts with special requirements are involved, MAPAL carries out basic work and develops target-oriented processes together with the customers. In some cases, experience from automotive engineering can be transferred directly to other sectors with appropriate modifications.

When wings or structural parts are milled out of large aluminium blocks on portal milling machines, often only 20 percent or less of the starting material remains. With the strong growth of the aerospace industry, the pressure grew to become faster in production with longer tool lives and better cutting data. What used to be a stronghold for carbide tools with indexable inserts a few years ago is now a field of application for mono PCD tools such as an SPM milling cutter from MAPAL. At 15,120 mm/min, its cutting speed is twice as high as that of the carbide cutter, and its tool life is up to nine times longer.

"Empower Your Aluminium Machining" is the motto of MAPAL's AMB presentation. Aluminium machining is an important focus, as are the Innovations 2025.

PCD tools are the first choice for highly productive machining of aluminium parts within the automotive industry. And yet the polycrystalline diamond lends itself to a wealth of other applications. MAPAL uses its extensive experience and the know-how on applications that ideally fit the strengths of PCD tools to develop individual solutions for optimum machining processes – together with the customer.

High process reliability is also important for the bores. An aircraft door requires up to 4,000 bores. CFRP, with its tendency to fray, places special demands on machining. MAPAL has developed special cutting edge geometries for this purpose in order to avoid delamination when exiting the material.
