He says that having created a 5-axis program for one-hit machining, they have occasionally needed to take it back to the pallet method, with a series of operations, when there were only certain machines free. As is the ability to transform the program from one technology to another. Sometimes an order that’s been programmed for the Matsuura MX 520 5-axis may need moving due to work rescheduling, so reposting it quickly and reliably to any other machine is vital. Their shopfloor comprises a number of 3-, 4- and 5-axis, and horizontal, machining centres from three manufacturers – Matsuura, Doosan and Hardinge Bridgeport.
He says EDGECAM helps achieve their success at the “trickier” end of machining because of its outstanding 5-axis capabilities, and the fact that a program can easily be edited not only for a different machine but for a different cutting technology.a point echoed by CAD/CAM Engineer Dominic Watson. I look at these medical components and wonder how on Earth would we make these without EDGECAM?”
“We’re taking on ever-more challenging jobs, but they rarely pose a problem to our engineering team. “We’ll assemble and laser mark, then bag and label them, so our customer simply supplies the hospital with what we’ve produced, complete.”ĮDGECAM CNC software is a vital ingredient in Claro’s prescription for providing a fast, reliable and versatile service. It includes a number of full assemblies comprising a series of items. Holding the ISO 13485 Medical accreditation, Claro is a second tier manufacturer, producing around 150 different types of medical components totalling thousands of individual parts a year. Claro Sales Director Mike Lewis says the sleeve has to be absolute high precision and burr-free as it stays inside the patient for the rest of their life. They also manufacture a sleeve in Ertacetal H for a pig’s heart valve which is implanted into heart patients, giving a live tissue solution rather than using a mechanical valve. Other products include instruments made from 17-4 ph stainless steel, used by surgeons carrying out hip replacements, to remove bone ahead of the implant going in. A current contract calls for them to machine an ankle trial bearing from medical grade plastic, requiring detailed contours. Around 30 per cent of Claro Precision Engineering Ltd’s work is 5-axis, carried out on four of their 19 CNC machining centres at 14,000 square foot premises in North Yorkshire.
