From interdisciplinary production to stand-alone complete machining
The rapid and pronounced success achieved by switching to five-axis complete machining made the HK management 'hungry for more' - especially as the need arose for additional capacity. And so it was that, soon after acquiring the first Hermle C 42 U high-performance 5-axis CNC machining centre, the decision was made to invest in another one. The two machines are virtually identical in their configuration: 800 x 630 mm NC swivelling rotary table, HSK-A 63 tool holding fixture, 42-pocket tool magazine, main spindle with max. 10000 rpm speed, Heidenhain iTNC 530 HSCI controller, high-pressure internal coolant supply system, touch probe, tool break monitor. Despite the different parts being machined, and the quantities ranging from 1 up to around 50, this makes it possible to maximise the available working times, and thus the machine running times, making component production much more productive in a multi-machine operation. Xaver Mayer sums up: 'It has all been well worthwhile, and to be honest we should have done it earlier. The fact that the swarf box was full three days after starting five-axis machining was a major positive surprise to us, because it was something we weren't used to. We also very much like the simple programming and easy operator control. And the rapid, expert service backup from Hermle is a major plus. The Hermle machining centres are now run 12 hours a day, literally in direct dialogue with the Design department, saving us a great deal of time and helping us avoid downtimes. We mostly run SE (Simultaneous Engineering) projects, initially working to only basic outline requirements, which are subject to change from start to finish. The faster our design and production systems are able to respond to those changing requirements, the less corrective action and cost will be incurred, and the fewer delays there will be. The two Hermle machining centres have been a major advance for us in that respect, and we have been able to significantly improve our competitiveness.'
