It Won't Be Moving! Genmitsu Vacuum Table for 3018-PROVer
A vacuum bed uses air pressure to push the stock down onto the bed by pumping out the air from underneath it, creating a partial vacuum. The resulting difference in air pressure applies a quite large clamping force evenly over the stock. Using the suggested vacuum pump (sold separately) a clamping force of ~12 lbs is exerted over every square inch of the surface. 85 kPA is also ~0.9kg per cm2. Let’s just say the stock is not moving unless you turn off the pump.
