ROEMHELD TO INTRODUCE NEW MACHINE VICE AT EMO 2023

German workholding equipment manufacturer Roemheld will launch a new, mechanically operated, centric (self-centring) machine vice on its stand (E54 in hall 4) at the forthcoming EMO 2023 metalworking trade show in Hannover, 18th – 23rd September. Manufactured in the group’s Austrian factory in Rankweil, the new Hilma.UC 125 vice is of modular build, intended for 3- to 5-axisprismatic machining applications. The design ensures easy tool access to the workpiece from all sides, allowing the use of short tools for high precision machining in a single set-up. Versatility in operation is ensured by having a separate vice base and two individual jaws that, when a single handle is turned, travel simultaneously inwards towards the centre to clamp the workpiece and out again to release it. Clamping force exerted via the upper DLC (diamond-like carbon)-coated spindle is up to 52 kN. A central bearing on the lower, unloaded spindle, which is used for positioning the jaws, ensures that each component is clamped precisely in the centre of the vice. Repeatability of workholding from part to part is better than ± 0.01 mm.

PRESS INFORMATION

As the clamping spindle is turned, force is applied to the workpiece via outer claws over the jaws. An active pull-down mechanism in the clamping jaws prevents the workpiece from lifting. Having both a tensioning spindle and an adjustment spindle prevents force being applied to the base, avoiding distortion. The universal clamp, hence UC in the product name, can be adapted to accommodate a wide variety of prismatic and round workpiece geometries and sizes in just a few steps. The jaw opening can be extended quickly to 600 mm, one of the largest available on the market. Numerous jaws up to 125 mm wide for securing a wide range of different raw and finished parts are offered as part of the modular system. Additional expense in buying extra workholding equipment is therefore normally avoided, even when production requirements are diverse. There are several options for mounting the vice. It can either be secured directly to the machining centre table, or in a zero-point clamping system. Adapter plates are available for added versatility.
