Roemheld has introduced four new, double-acting centric vices, the H 4.400 range, for use in restricted working areasA new range of four double-acting, self-centring (centric) vices of particularly compact design for demanding clamping applications in restricted working areas, has been introduced by Cramlington-based
Roemheld UK Ltd. These vices are suitable for milling, drilling, grinding, electric discharge machining and fixture building applications.
The H 4.400 power clamp is available in two sizes of base, 64 or 100mm square, which is contoured below the jaws to provide good accessibility to all five sides of a clamped component and promote free chip evacuation during machining. Jaw actuation is either hydraulic or pneumatic; the small and large hydraulic versions deliver 4.8 and 20.3 kN of clamping force respectively, while the pneumatic variants are rated at 4.0kN and 14.0kN.
The double-acting piston with backlash-free transmission of force to the two base jaws means that all models are suitable for internal or external workholding. The jaws move synchronously and concentrically, enabling precise workpiece positioning to within 5µm. The high rigidity of the vices and their hardened surfaces ensure long-term wear resistance, minimising the need for maintenance.
A standard feature is a connection for positive air pressure to protect against ingress of liquids and dirt particles. A comprehensive range of options is offered, including various quick-change jaws and mounting options, monitoring of clamping stroke and part position, zero-point adaptation, sensors for process monitoring, a port for centralised lubrication and RFID chip recognition for tracking and data management. These and other accessories allow extensive customisation possibilities and seamless integration into a wide range of production environments, including those involving automated part handling.
