VAC-MAT Polymer Mats by Witte – Precision Vacuum Clamping Without Compromise
Witte’s VAC-MAT polymer mats offer a highly effective solution for vacuum clamping, allowing workpieces to be fully machined in just one setup. Whether milling, drilling, grinding, or carrying out 5-sided machining – including all cut-outs – VAC-MAT handles it all with ease. Even complex contours and chamfers, which usually require specialist chucks, can be machined accurately and cleanly.rnrnDuring operation, up to 70% of the workpiece surface can be removed without losing vacuum or causing parts to shift or release unintentionally. The process eliminates the need for reworking tasks such as breaking off workpieces, deburring, or using clamps or double-sided tape, streamlining production and saving valuable time.rnrnVAC-MAT also ensures high holding force and a clamping surface with excellent friction, allowing through-milling of both inner and outer contours. The result is precise, burr-free edges and a clean finish.rnrnHandling is quick and simple – workpieces are clamped within seconds, without the need for seals, special fixturing, or risk of surface damage. The gentle contact prevents scratching, making VAC-MAT suitable for sensitive surfaces. Modular versions are available to accommodate larger clamping areas, offering even greater flexibility.
