A range of compact work-holding systems suited to metal-cutting operations on five-axis machining centres has been introduced by Roemheld UK. The SCS vices are manufactured by the German group’s Hilma division in Hilchenbach.

Hilma’s fixed-jaw SCS vices are designed to allow good accessibility of tools to the component. It means that five-sided machining can be achieved without collision using short standard tools, lowering costs and improving workpiece accuracy due to the generation of less vibration.
Stable clamping systems and the high retention force resulting from the use of a reversible jaw mean there is no need to pre-stamp a workpiece before it is secured, even when it is clamped on just a few millimetres of material. Repeatability of positioning is to within ±10 µm.
The SCS work-holding systems have comprehensive swarf protection, so are suitable for use in multi-pallet prismatic machining cells. Operation is either mechanical, via a threaded spindle and torque wrench, or hydraulic, using a single-acting cylinder to effect the clamping pressure, with unclamping achieved by spring force.
Base lengths up to
350 mm are offered, with different clamping ranges to 300 mm, while clamping force is up to 40 kN at 100 Nm torque. A range of hardened and ground jaws, as well as soft jaws, in 80 and 120 mm widths to suit the various vice models, is available, as are customised versions in other lengths, or with individual mounting holes, including for zero-point clamping.

The Allmatic range of German-manufactured vices, which is offered in the UK by Stocdon, is said to be a high-end solution for work-holding applications that include the three or five-axis machining of prismatic parts, as well as non-prismatic components like castings and forgings.

What makes Allmatic solutions different to the rest on the market is that they often fulfil the complete needs of a customer’s application, says Stocdon, where previously they had to spend time using multiple vices or resetting vices between applications.
Allmatic’s engineering allows users to pre-select working pressures, use minimum material work holding and grip rough materials.
The latest Allmatic Gripp solutions are said to lead the way when it comes to all types of component selection, with large capacity, high clamping force up to 7 tonnes and minimum deflections, for easy setting.
Allmatic has been a work-holding partner of Stocdon since 1972, largely because of the company’s pedigree when it comes to accurate pre-selection of material clamping pressures. The vice performance, across the range, is second to none, says the company.
According to Stocdon, a question that clients always ask when enquiring about Allmatic work holding is the cost, versus other brands, to which the company always showcases the savings to be made in the long term. Stocdon knows that budgets are always under pressure, but it also knows that investing in work holding pays dividends, long term.
