CR 03 100

All Star CNC CR 03 100 Round Vacuum Gasketing — Frequently Asked Questions

1. What is CR 03 100 Round Vacuum Gasketing?

CR 03 100 is a round-profile vacuum gasket designed for CNC router spoilboards and dedicated vacuum fixtures. It installs into routed round channels to create a secure air-tight seal and improve hold-down strength.

2. What do the numbers “03 100” represent?

“03” indicates approximately a 3/32″ (0.093″) height profile, and “100” indicates a 1″ (1.000″) diameter round gasket configuration.

3. What does “CR” mean?

CR designates a round-profile (cylindrical) gasket style, commonly used in CNC tables designed for round-channel vacuum grids.

4. When should I use a 1″ diameter round gasket?

A 1″ round gasket is typically used in large-format CNC vacuum tables or custom fixtures that require substantial sealing surface area.

5. How does round gasket differ from flat in-board gasket?

Round gasket provides a raised compression profile that seals evenly within round-channel routing, whereas flat in-board gasket is designed for rectangular grooves.

6. What CNC machines is CR 03 100 compatible with?

It is compatible with CNC routers and vacuum tables that use routed round-channel grid systems.

7. What materials benefit from this gasket?

MDF, plywood, hardwood panels, plastics, aluminum composite materials, and other sheet goods benefit from improved vacuum hold and reduced part movement.

8. Is CR 03 100 adhesive-backed?

Yes. The gasket includes adhesive on one side for easy installation inside routed round channels.

9. How long is each roll?

Standard rolls typically contain approximately 164 feet of gasket material.

10. Does round gasketing improve vacuum performance?

Yes. Properly installed round gasket improves vacuum isolation, increasing suction strength at the part location.

11. Can this gasket be used in custom CNC fixtures?

Yes. It is commonly used in dedicated vacuum fixtures requiring repeatable, high-accuracy sealing.

12. Does it improve machining accuracy?

Yes. Stronger vacuum hold reduces vibration and part shifting during CNC cutting operations.

13. Can it reduce the need for mechanical clamps or tabs?

Yes. Improved vacuum sealing can reduce or eliminate the need for mechanical hold-down devices in many CNC applications.

14. Is CR 03 100 suitable for nested-based CNC routers?

Yes. Nested-based routers benefit from proper vacuum isolation to maintain stability of smaller parts during machining.

15. How do I confirm this size is correct for my table?

Measure the diameter of your routed round vacuum channels. The gasket should fit securely without excessive compression or looseness.

16. Does wider diameter increase sealing surface?

Yes. A larger diameter gasket increases compression surface area, which can improve vacuum isolation when matched to adequate vacuum capacity.

17. Is this gasket reusable?

Once installed, it remains in place until wear or compression fatigue reduces performance. Replacement is recommended when sealing effectiveness declines.

18. Are other round gasket sizes available?

Yes. All Star CNC offers multiple round gasket diameters and profiles to match various CNC vacuum table designs.
