The vacuum workholding system you can cut right into! A unique method of vacuum workholding using a patented plastic mat which keeps the part securely held down even when penetrated by the milling cutter, so windows, pockets and profiles can be machined in one set up giving tremendous productivity gains over conventional vacuum fixtures.
What is a VAC-MAT?
It is a thin soft plastic mat with a uniformed top face of 77 vacuum suckers in two different sizes each with a fine hole in the centre and a raised lip. On the underside of the mat there are six lugs which locate in the Vac-Mat fixture plate and a distribution grid of grooves to each hole for extracting the air. A lip right around the outside mat edge ensures no leakage.
What size is VAC-MAT?
All Vac-Mats are one size 300x200x 2.5mm. The mat tolerance lies at ±0.04mm and concave up to 0.1mm. To increase the size of the working area, the mats are placed on modular fixture plates that interconnect.
Are there different types of VAT-MAT?
There are 5 types’ available each with their own colour for identification.
How many times can a VAT-MAT be used?
The working life of a VAT-MAT depends on the machining application. If the mat is cut into during machining it is unlikely that you can re-use the mat. If the application does not cut the mat it can be re-used generally until a noticeable deterioration in the sucker lips. Higher machining heat will generally mean re-using the mat less.
What sizes are the fixture plates?
The plates come in two sizes 300x200x31.5mm or 600x400x31.5mm and are inter connectable to form larger fixtures.
