Rotec achieves lights-out manufacturing

A specialist supplier of components to the aerospace, automotive and oil and gas sectors has invested in the latest five-axis technology and CADCAM software to reduce set-up times and achieve lights-out manufacturing.

Rotec Engineering, which offers fixed-head and sliding-head capabilities from its facility in Evesham, has installed a Nakamura NTRX 300 from the Engineering Technology Group (ETG), building on a long-term relationship with the machine tool supplier.
“In our endeavour to move forward and expand, we wanted a machine with all of these attributes that we could also program directly from our CAM system with full five-axis turning,” says Paul Butler, managing director and owner of Rotec. “We found that just focusing on cycle time wasn’t the right way forward for our business. There is often a lot of downtime between jobs, so the whole idea of this investment is to apply the CAM system and machine flexibility to reduce our set-up times.
“Now, we can set-up complex jobs very quickly and, with a bar feed and auxiliary loader, we can run these challenging parts unmanned and they come off the machine complete,” he adds.
ETG, which is the UK’s exclusive supplier of Nakamura technology, worked with Rotec to source a machine that matched its exact requirements, with the NTRX 300’s milling head and two rotating spindles proving extremely attractive. The challenge was to get all the technology to work seamlessly for the company so that the machines could be trusted to run when employees are not on site.
