One of first Matrix pin vices in use in the UK is producing a time and cost saving solution when finish machining prototype and first-off complex free form parts created using the additive manufacturing technique (AM).
The vice was supplied by ETG Workholding to Renishaws Digital Manufacturing centre (DMC) based at its HQ site near Wotton-under-Edge where self-sufficiency plays a major role with prototyping and component development projects undertaken using Renishaws own RenAM 500M additive manufacturing systems. The Centre also doubles as a demonstration facility for Renishaws extensive AM manufacturing expertise.
RenAM 500M systems use metal powder bed fusion technology to build complex components straight from the digital CAD files. Many are prototypes for future Renishaw machine and process developments but almost without exception, all feature complex shapes, thin wall sections or have complex geometries. As a consequence, they are difficult to clamp when being finished machined.
Traditionally in these circumstances, a fixture would have to be created involving an initial CAD drawing, prototyping, machining and assembly with inevitable time and cost implications. Now, using Matrix pin vices, Renishaw technicians can create a part specific, stable, secure and repeatable workpiece clamping configuration that can be set up in a matter of minutes.
Renishaw has two versions of clamps from the Matrix Silver X-clamp range two rail mounted X clamp 40s for small components and a larger X clamp 125 version which has the capability to offer wrap around clamping to create an optimised grip on the work piece. Both are superior to conventional two or three point holding devices where there is also the risk of surface damage at the clamp points.
