Roeders RPT600DSH five-axis machining centre incorporating NANOTOL and PRECITEMP technologiesGerman machining centre manufacturer
Roeders GmbH, whose products are sold into the UK and Irish markets exclusively by
Hurco Europe Ltd, High Wycombe, will be presenting three new RPT-series models at
EMO Hannover 2025, which takes place 22-26 September (Hall 12, Stand C06). They incorporate the innovative developments NANOTOL and PRECITEMP, which not only allow extremely tight tolerances to be achieved, but also very high surface quality.
NANOTOL is integrated into the linear guideways to improve the running behaviour, while PRECITEMP technology manages temperature fluctuations to maintain geometric stability within ±1µm, even with a 3°C temperature variation in the workshop. In consequence, RPT machines achieve machined tolerances twice as tight as the already very accurate RXP series from Roeders.
What a machine is really capable of only becomes apparent when milling complex geometries. Due to high toolpath accuracy, it is possible to produce optical quality surfaces quickly. For example, a 20mm diameter convex surface with an Ra less than 10nm was produced in just 2hr.
In terms of geometric accuracy, a 150mm square aluminium block was machined on five sides to less than 1µm flatness and straightness. Holes machined into hardened steel have a pitch tolerance of less than one micron and cylindricity of under 0.5µm. Target industries for these three-axis and five-axis machines include mould and die making, aerospace, and medical prosthetics manufacture.
