The 18" x 36" Vacuum Chuck and Air Venturi Vacuum Pump Complete System Includes All the Items Needed To Get Started Vacuum Workholding Quickly
This Complete Vacuum Chuck and Pump System includes everything needed to get started Vacuum Chuck Workholding.
- 18" x 36" Precision Ground Aluminum Vacuum Chuck with 1/2" spacing between the Gasket Cord Slots and
16 vacuum access holes on the face of the Vacuum Chuck.
- No Clog Air Venturi Vacuum Generator Pump with 1/4" NPT which creates the vacuum using com
pressed air.
- No Clog Air Exhaust Pneumatic Muffler. (The No Clog design of the Air Venturi Vacuum and Air Silencer helps prevent potential clogging from debris while machining).
- Gasket Cords for holding a wide range of workpiece sizes.
- Vacuum Port Connection with Air Supply Shut Off Valves and Vacuum Gauge. The
4-Port Connection threads into 4 Vacuum Port Holes on the Vacuum Chuck.

18" x 36" Vacuum Chuck & Air Venturi Vacuum
Complete System:
18" x 36" Complete System Details:
| 18" x 36" x 1.5" Vacuum Chuck & 4 Port Vacuum Connection |
|

- The 18" x 36" Vacuum Chuck is produced from flat ground hi-tensile cast aluminum plate.
- Vacuum Chuck has 4 individual vacuum ports with 4 vacuum holes per port (total of
16 vacuum holes). This allows for flexible use of the entire top surface. Each vacuum port can be shut off individually.
- 1/2" spacing between the gasket cord slots maximizes vacuum holding power and provides for flexible workpiece placement. This optimizes the table space and maximizes the amount of the workpiece exposed to the vacuum.
-
This Vacuum Chuck is designed to use two Gasket Cord sizes.
- Gasket Cord
for smaller workpieces, 1/8" x 5/16" (Part No.: 10543).
- Gasket Cord for larger workpieces, 3/16" x 5/16" (Part No.: 10544).
- The 4 Port Vacuum Assembly includes Vacuum Gauge and multiple Air Shut Off
Valves.
- Additional threaded holes in the top surface of the Vacuum Chuck allow for use of
Workstops to align workpieces and to attached a Replaceable Top Plate.
- The Vacuum Chuck design allows for material to be removed from the top surface of the vacuum
chuck if damaged during use, or needs to be re-machined flat after use.
- Multiple Vacuum Chucks can be used in the same CNC Machine to create extremely large vacuum workholding areas.
- This Vacuum Chuck is a shipped ground flat. The design allows for skim cut removal of material to re-flatten the surface if necessary.
- Replaceable Top Plates are available separately. Drill Through Top Plates connect to the top surface of the Vacuum Chuck and prevent damage to the Vacuum Chuck when cutting
through workpieces. Details below.

Air Venturi Vacuum Generator Pump |
|

- The 1/4" NPT Air Venturi Vacuum Generator Pump creates a vacuum using compressed air.
- Straight through, filter free design helps prevent clogging.
- The vacuum operates by supplying compressed air to the supply port. When
air pressure is applied, the Venturi creates a vacuum at one end and the air is exhausted out the other end.
- Vacuum Flow (SCFM): 4.5
Amount of Supply Air Used (SCFM): 5
Diameter of straight through vacuum flow path (Bore Diameter): 0.20" (5 mm)
- Workholding / Fixturing calculations:
Hold down force is calculated simply by:
Force = (area of part being held in sq. in.) x (vacuum in psi).
For Example, if you are using a 3" round suction cup to hold a part the force applied to the part is:
7.069 x 11.8 psi = 83 lbs. of holding force (For reference: 24" HG=11.8 psi)
Where 7.069 is the area of the circle (πr2) = 3.14159 x 1.52

Generator.

No Clog Air Exhaust Silencer |
|
- 1/4" NPT.
- This silencer is used to quiet air exhausted from the Air Venturi Vacuum.
- Straight through filter free design limits possible clogging by debris.
|
| Vacuum Hose Kit |
|

- Hose allows your vacuum to be located away from your machine.
- 1/4” NPT and 3/8” NPT connectors.
- Kit includes: Hose: 10 feet length, 2 - 5/8” hose barbs, 2 - 3/8" F NPT - 1/4 M NPT Hex Adaptors, Hose Clamp.

Gasket Cords
Two different sizes are provided in this Complete System |
|

- Gasket Cord for smaller workpieces, 1/8" x 5/16" - 50 ft., (Part
No.: 10543)
- Gasket Cord for larger workpieces, 3/16" x 5/16" - 50 ft., (Part No.: 10544)
- Gasket Cords are designed to fit into the slots of our large Vacuum Chucks: 13" x 25", 18" x 36" and 24" x 48" and provide a vacuum seal.
