Integral automated processes boost efficiency
DMG MORI is a long-standing partner for manufacturers of medical technology – twelve of the 20 largest players are among the company’s customers – and is well acquainted with the special challenges in mechanical production. “The technological possibilities are not, for example, the limiting factor here. Instead, it is the high demands in the certification requirements of medical products that determine the process in medical technology”, says Marcus Krüger, Head of the DMG MORI Medical Excellence Center. Where production solutions are concerned, it has therefore become more important than ever to integrate digital solutions very early on in the production process. “Barcode readers, the measurement and marking of parts as integrated options in CELOS, and thus also in the production process, will both simplify and accelerate documentation and tracking.” Automated processes include virtually unmanned production, but also the reading of programmes, quantities and batch sizes in the production environment as well as feedback to the entire system.
Marcus Krüger considers automation solutions generally a great trend in many sub-disciplines: “This involves the loading and unloading of single parts and small series in orthopaedics. The focus here is on flexible automations, as it is in the production of medical instruments.” Due to the high quantities, machining from the bar is preferred here. “The limited production areas in this sector necessitate space-saving, integrated automation solutions”, adds Marcus Krüger. DMG MORI has these in its portfolio in the form of pallet and workpiece handling systems and robotic automations.
DMG MORI Medical Excellence Center: With innovative solutions into the medical technology future
Based on its wide-ranging product portfolio, DMG MORI develops optimum manufacturing solutions for its customers from the medical technology sector. In the DMG MORI Medical Excellence Center, set up specifically for this purpose at DECKEL MAHO Seebach, the experts of the machine tool manufacturer realise innovative turnkey solutions for both industry giants as well as smaller companies and suppliers that enable cost-effective production. Engineers are involved early on in the development phase of our customer’s projects. So they learn a lot and integrate the knowledge thus gained in the construction of our machines and components in order to design ever more efficient manufacturing solutions. This was put to the test impressively during the first Medical Days that took place last June at DECKEL MAHO Seebach. Customers from Germany, Switzerland and Ireland discussed the increase in productivity for medical technology with experts from all fields.
A study undertaken by Avicenne indicates the industry will grow on average by 4.4 percent in the coming years. This trend will be accompanied by continuous price pressure. „Certification issues will also become more acute and will have an impact on production”, adds Marcus Krüger. The challenge we face is exactly that, to overcome such hurdles and to ensure that “both the high demands on quality and low machining times are met with innovative production solutions.”
Space-saving machine tools for every application
The efficient high-performance CNC machine tools from DMG MORI are and remain an essential basis for economic automation solutions. Here too, users prefer a footprint that is as compact as possible. That is why models such as the compact machining centre MILLTAP 700 and the SPRINT automatic turning machines dominate here as well as the DMU 50 and the smaller DMU eVo models for 5-sided milling and the NTX 1000 2nd Generation in 6-sided complete machining. With this portfolio, DMG MORI covers a wide range of components in the all important orthopaedic field.
Precision milling in five axes with up to 60,000 rpm
The high demands on quality and the need for shorter machining times are aspects that the entire range of products in medical technology have in common. “So complete machining is a commonplace topic in the industry”, says Marcus Krüger. In particular complex parts such as knee implants made of cobalt-chrome can be manufactured with maximum efficiency in 5-axis simultaneous machining on a DMU 40 eVo linear. “speedMASTER spindles with up to 30,000 rpm or spindles with up to 60,000 rpm for the HSC 20 linear achieve surface qualities that require a minimum of post-processing effort.” The dynamics and positioning accuracy of the linear drives make these ideally suited to such requirements. With the aid of the PH 10|100 pallet handling system, for example, DMG MORI ensures a high level of productivity in this area for even the lowest quantities.
