Roemheld self-centring viceThe PC80Z self-centring vice is available in a new, two-in-one version that accepts the manufacturer's optional round inserts, enabling cylindrical components or billets from 44 to 95mm in diameter to be clamped securely, says Roemheld.

The company says the vice can be converted back within a couple of minutes to its conventional role of holding prismatic components. It simply requires the Allen bolts holding four round inserts to be unscrewed and the pair of straight, 80mm wide jaws to be reinstated. Parts from 17 to 139mm long can then be secured for metalcutting using the 62mm clamping stroke. It’s claimed to be suited for use on 5-axis machining centres and in automated production cells employing pallet magazines.
