Manufacturing cast and VA housings with RÖHM key bar chuck DURO-TA XT

On request, cast and VA housings are mainly created with tremendous reliability as one-off productions from the idea, continuing with the development and right up to manufacturing. NTG recently invested in an ultramodern turning/milling centre from DMG to manufacture them. To make sure that the DMC 210 FD can utilise its capacity as flexibly as possible, NTG chose a DURO-TA XT manual chuck from Röhm. The latest chucks from Röhm with an impressive 1200 mm diameter are characterised by their compact design, workpiece accessibility and flexibility despite their size.

IWC Schaffhausen manufactures watch boards with a RÖHM power-operated index chuck in just one clamping position

To guarantee a high standard of process reliability and repetition accuracy, IWC Schaffhausen uses the ultra-compact 5-axis machining center KERN Micro for the operation. In this machining center, the prizewinning power-operated index chuck from RÖHM’s Micro Technology series is installed. The index chuck enables doublesided machining of boards without changing the clamping position. This makes it possible for IWC to achieve maximum precision and repetition accuracy in just one clamping position with dozens of machining steps and any number of tool changes being involved.
