The company hg medical from Raisting in Upper Bavaria is considered one of the leading subcontract manufacturers of these special screws. To produce them, hg medical relies on Swiss-type lathes from Traub and whirling tools from HORN. In addition to conventional whirling, hg medical uses the high-speed whirling process.
"By switching to gear skiving and investing in a turning/milling centre from INDEX, we have achieved maximum process reliability," says Erwin Wagner. Wagner is responsible for tool scheduling at SAM GmbH in Bad Tölz. The company is considered a specialist in the development and production of high-quality components for aircraft construction.
Precision tools, accurate lathes and a deep understanding of how to use the two to achieve micron precision. This describes the cooperation between Paul Horn GmbH, the machine manufacturer INDEX and the contract manufacturer of precision turned parts, RICH Praezision.
In Leutkirch in the Allgäu, the company zmtec produces everything from microcomponents to complex assemblies. The specialities include micro-turned parts from a diameter of 0.5 mm (0.020").
“We branched out into the sectors that others had avoided”, says company founder Walter Schumacher. Together with his son, Stefan, he runs the company Walter Schumacher Impuls Technik GmbH, (SIT). The company specialises in the development and production of special valves and stand-alone valve solutions, which are used in numerous industries.
High concentration is required. Rejects when setting and running in components is a normal process in almost every production: call up the programme, manufacture the part, measure, correct, manufacture a new part - until it fits. This is different in the machining of large parts. Here, the machine operators carefully feel their way to the final dimension to be produced.
