Amada Miyachi Europe announces that it will highlight a range of laser and resistance welding equipment ideal for the medical industry at Medtec Europe, to be held 12-14 April, 2016, at Messe Stuttgart, in Baden-Württemberg, Germany.
On display will be the Jupiter Fiber Laser Welding System, ideal for spot welding surgical tools and seam welding implantable devices, as well as a vacuum chamber module that can be integrated into a pacemaker welding system. Also to be showcased is the Series 320 low force electronic weld head, a resistance spot welding head ideal for medical applications requiring precise position and force control.
The MIYACHI EAPRO Jupiter Fiber Laser Welding System on display is designed for fast, accurate and reliable welding on all kinds of surgical tools and medical devices, including hearing aids, catheters and brachyseeds. The fiber laser’s low power level and high beam quality allows power up to 500W to be fired into 10 or 20 micron cores, resulting in very small weld spots. Depending on the application, the system can also be equipped with several types of lasers and optics to suit the speed and accuracy required for medical applications.
Also on display is a vacuum chamber module specially designed for laser welding packages under vacuum or shielded atmosphere. This shielded atmosphere module for laser welding systems can be integrated into a full-sized glovebox. It is designed to fit inside the next generation of NOVA6 CNC Laser Welding Workstations, which are used for manufacturing pacemaker leads, medical implants, and sensors.
The all-new Series 320 electronic weld heads on display are high precision low force heads designed specifically for applications requiring precise position and force control. The versatile resistance spot welding head has features that meet the process demands of microelectronics manufacturing, including inline and offset opposed electrode configurations and the ability to set displacement limits and use the weld-to-displacement feature to stop the weld precisely during collapse. It is also robust enough to endure industrial requirements and environments.
Arburg received the international “Leonardo da Vinci” Award on 17 March 2016 in Parma, Italy during the MECSPE trade fair. The Italian Association of Industrial Designers AIPI (Associazione Italiana Progettisti Industriali) awarded this prize to acknowledge the design of the Freeformer, an innovative system for additive manufacturing.
“I’m delighted to accept this coveted award on behalf of Arburg Italy. Our Freeformer is unique – both in terms of design and the numerous options that it offers to plastics processing companies for the additive manufacturing of fully-functional one-off parts and small batches,” said Managing Director Adriano Carminati at the award ceremony, which was held during the MECSPE trade fair in Parma, Italy.
International design award
Established by Italy’s AIPI association in 1981, the international “Leonardo da Vinci” Award is presented every two years to individuals and companies who have made a valuable contribution to design and technical innovation for the industry. In addition to Arburg, this year’s recipients included Italian engineer Aldo Costa, who has designed and developed 32 Formula 1 racing cars, the Helicopter Division of Finmeccanica, and cycling company Victoria.
Innovative Freeformer for additive manufacturing
In order to also achieve a high level of production efficiency during the production of small batches down to a single unit, Arburg complemented its Allrounder injection moulding machines with the Freeformer for additive manufacturing, which it introduced to the Italian market in 2015. The Freeformer uses an additive manufacturing process to produce fully-functional plastic parts from qualified standard granulates on the basis of 3D CAD data.
Convincing industrial design
In 2014, the Freeformer already received the renowned Red Dot Award for “excellent product design”. Examples of how aesthetics and functionality have been combined include an easily accessible construction chamber with pivoting glass front, simple operating options and a fold-out PC with multi-touch screen mounted on the side. The clear, soft lines of the housing are reminiscent of modern telecommunications devices and are well suited for use in a design studio or laboratory environment. The fact that the overall concept is successful in visual terms is evidenced by the positive feedback from existing and prospective customers.
When material savings are a requirement due to machining expensive materials, large batch productions, or both, it is essential to use the thinnest insert width possible. CoroCut QD dedicated parting off and deep grooving tools are now available in smaller insert widths with internal high-pressure coolant to help customers realize production efficiency.
Realized material savings
Considered a “hidden machining cost,” component material waste is an often-overlooked production expense. Wider insert blades cut away more material than necessary during each parting off operation with the excess material ending up in the chip bin. Using a thinner insert blade not only wastes less material but also allows for more parts per bar when parting off using a bar feeder. Realizing this material savings is especially important for those who machine components made of expensive materials, such as heat resistant super alloys (HRSAs) like Inconel, titanium and cobalt chrome. When working with these high-priced materials in higher volumes, using a thicker insert blade can be costly.
For smaller insert widths, insert handling is easily accomplished with the use of the insert cam key. Accompanied with each CoroCut QD, the cam key allows the user to leave the finger of the blade in the open position allowing for use of both hands for insert positioning. With the turn of the cam key, the new insert clamp design offers improved rigidity for process security. CoroCut QD toolholders are made using the same improved tool steel as the larger width CoroCut QD, resulting in 12% higher tensile strength.
According to Staffan Lundström, Parting and Grooving Product Specialist at Sandvik Coromant, “As the only product currently on the market that offers over and under coolant in a tool this thin, the CoroCut QD inserts in 1 mm, 1.2 mm and 1.5 mm work well for deeper cuts and larger diameters and for all materials, especially HRSAs.” Parting and Grooving Specialist Scott Lewis adds, “Shops that solely focus on tool costs can be missing the big picture. When a tool costs you more in material waste over time, especially expensive materials, the overall cost to machine a component can be much higher than expected.”
