What is a VAC-MAT vacuum mat? It is a thin, soft polymer mat with many spaced-out vacuum points, suckers of different sizes with a fine hole in each centre and a raised lip. On the underside, there are six lugs which locate in the special VAC-MAT™ chuck. On the mat’s surface, there are grid-shaped grooves which distribute the vacuum to each of the small holes. A lip right around the outside edge ensures no leakage. What size is VAC-MAT™? All VAC-MAT™s are 2,5 x 200 x 300 mm. The tolerance is ±0,04 mm and concave to 0,1mm. To increase the size of the working area, the modular VAC-MAT™ chucks are connected, and VAC-MAT™s are placed on them. Is VAC-MAT™ reusable? The working life of a VAC-MAT™ depends on the number and size of cuts made into the mat during machining. Operating temperature for VAC-MAT™? VAC-MAT™, available in RED, BLUE and GREEN versions can be used at 40°C without any limitations Downloads Vac Mat WITTE Vacuum Catalogue-2024.pdf   Why WITTE VAC-MAT™ is the right choice for you. Application Wide spectrum of different workpiece forms can be clamped Milling Drilling Grinding Five sided treatment including milling into the VAC-MAT™ Advantages Strong hold down force Clamping surface with a high friction value Milling through of outer and inner contours Precise and exact cut outs due to the fact that the workpiece can be milled through into the VAC-MAT™ leaving a clean cut edge Handling Set up time reduced to seconds as fitting of single rubber seals become obsolete Surface friendly material which avoids scratching of workpiece surface area No extra clamping fixture needed
