Direct Mount using Grid Gasket is a fast and economical way to set up a part. Simply align a gasket based on our 1” grid layout. You can achieve any shape or size, and create multiple independent vacuum zones for multiple parts.
When you are done, simply remove the gasket, and you have a clean grid pattern to create a whole new arrangement for your next cut.
With this method, you do not want to cut below the bottom surface of your part, since the table is sitting directly below the workpiece.
Follow these steps to ensure success when using the direct mount method:
1. Use grid gasket (no adhesive) to create a sealed zone underneath your stock. The zone must contain at least 1 vacuum port.
2. Plug all remaining vacuum ports. Don’t forget the corner(s)!
3. Place your stock material over the sealed zone, making sure your stock completely covers the gasket material.
4. Turn on your pump and apply downward pressure to your stock to help create a seal.
5. The sound of your vacuum pump will change, pressure difference will increase and your part will be rigidly held.
6. Make sure to leave a .050” “onion skin” at the bottom of your cuts when using this method. DO NOT CUT THROUGH or you may damage your vacuum table and lose vacuum pressure, depending on the gasket approach.
7. Use a secondary process (trim router, drum sander, sanding whip, etc…) to remove the remaining onion skin from your part.
Material Tips: Your stock material must be flat for the vacuum table to create a seal and firmly hold your stock. If you are struggling to create a strong hold, consider using individual pieces instead of longer boards or large sheets containing multiple pieces. Always place your material concave side down and apply pressure to support vacuum sealing when seating your stock.
