Complete Vacuum Workholding Systems:
8″ x 12″ Modular Vacuum Chuck Kits & Automatic Vacuum Pump

• These Complete Systems include either one or two Modular Vacuum Chuck Kits, the 4.5 SCFM Automatic Vacuum Pump for the vacuum supply, and accessories.
• Modular Vacuum Chuck Kits allows you to use one Modular Vacuum Chuck Pallet or combine several to increase the workholding area.
• Quickly create different size & layout vacuum workspaces using the Modular 8″ x 12″ Vacuum Chucks.
• Threaded holes on the face of the chuck can be used for vacuum, clamping, or locating the workpiece.

Gasket and Hold Down of Workpieces

• Quickly seal off the vacuum holding area by using 1/8” diameter Gasket Cord or 8” x 12” Gasket Sheet.
• Gasket Sheet can be trimmed to fit underneath specific workpieces.

Prototype Parts Quickly

• The 77 holes on the Vacuum Chuck top are threaded with accurate 1” spacing to allow placing low profile Adjustable Edge Clamps and Workstops anywhere on the Vacuum Pallet.
• This flexible design reduces set up times and eliminates the need for custom fixtures.
• There are 29 vacuum/clamp holes on the pallet top.
• Eliminates the need to create custom fixtures and allows easy prototyping of workpieces.
• Flexible configuration and set up allows you to prototype parts quickly.

Fits in a Standard Milling Vise

• Hold the Modular Vacuum Chuck in a standard milling vise or attach a Vise-Block for vise openings as small as 5”.

Repeatable For High Production

• Allows for quick and repeatable set up.
• Repeatable workpiece position between Pallets for high production. Load one Vacuum Chuck off-line while another is being machined.
• Numbered locations on the face of each Vacuum Chuck allow for repeatable and consistent workpiece placement.
• Quick Vacuum Gasket Cord placement allows easy workpiece size changes.
• Threaded Hole locations are labeled/numbered to allow documenting setups.
• The Vise Stop-Pin locates Pallet in the milling vise.
• Hex Workstops, Adjustable Edgeclamps, Side and End Workstops locate the workpiece consistently.

Drill Through Workpieces

• Replaceable Top Plates and the low slip Vacuum Gasket Sheets allow drilling through and machining around the outside of the workpieces without damage to the Vacuum Chuck.

Vacuum Supply

• Only one Vacuum Pump is required when connecting multiple Vacuum Chucks together.
• The Automatic Air Venturi Vacuum Pump accommodates a 1,200 sq. in. sealed Vacuum Chuck.

Hold Parts On A Magnetic Chuck

• Hold parts on a magnetic chuck by attaching the Steel Vise Block. Vise Block allows holding Aluminum, Plastic, and thin workpieces on a magnetic chuck for surface grinders.

Use as a Pallet for Fixturing Without the Vacuum

• The Modular Vacuum Chuck can be used as a Pallet for fixturing without the Vacuum by using low profile Adjustable Edge Clamps and Workstops.
• Low profile Adjustable Edge Clamps and Workstops reduce set up time and eliminate the need for custom fixtures.
• Adjustable Workstops and Edge Clamps can hold a wide range of height and size workpieces.

The Automatic Vacuum Pump System can be used for vacuum workholding, fixturing and vacuum forming.

This Automatic Vacuum Pump can be used with all of the 2L Modular Vacuum Chucks, Large Vacuum Chucks, and many other vacuum workholding systems.

It creates a vacuum using standard shop air pressure and automatically turns on and off as required to maintain a set point. The Automatic Vacuum Switch controls the operation of the Vacuum Pump. As the vacuum level drops in the storage tank, the Vacuum Switch turns the Vacuum Pump on until the upper limit of the vacuum is reached. Once the upper vacuum limit is reached the Automatic Vacuum Pump shuts off. The Automatic Vacuum Pump cycles on and off automatically as needed, therefore constant monitoring is not necessary.

• 4.5 SCFM Vacuum Pump, uses 5 SCFM of Compressed Air.
• 10.5 Gallon Steel Tank with Wheels, Handle, and a Bottom Drain.
• Maximum vacuum generated is 22″ HG – 26″ HG (10.8 psi – 12.8 psi)
• Only 70-80 psi air pressure is required to obtain the maximum vacuum.
• Automatic on/off Adjustable Vacuum Switch allows the Vacuum Pump to be left unattended for periods of time.
• 3/8″ NPT Vacuum Inlet Port.
• Large visible Inlet Filter with washable metal vacuum filter acts as a coolant trap to help keep contaminants from entering the tank.
• 110 VAC / 0.5A power connection.
• Vacuum Gauge with 2” diameter dial, Steel Case and Plastic Lens.
• Integrated air regulator with pressure gauge to adjust air pressure set point.
• Ball valve drain on the tank bottom.

• Precision Ground Aluminum Modular Vacuum Chuck.
• 8″ x 12″ x 1.45″
• 77 threaded 1/4”- 20 holes.
• Threaded hole locations are labeled/numbered to allow documenting setups.
• 1.0” hole spacing for clamps allows for quick and accurate workpiece placement.
• 29 Vacuum Holes per Vacuum Chuck Pallet. One horizontal row of 11 vacuum holes and 3 vertical rows with an additional 6 vacuum holes each.
• Only one Vacuum Pump is necessary for multiple Vacuum Chucks.
• Connect multiple vacuum chucks with Vacuum Connector, which allows allows use of only one Vacuum Pump.

The Vacuum Manifold is used to connect the Modular Vacuum Chuck to the Air Venturi Vacuum Pump.

• 1/4” NPT threads.
• Manifold includes:
  • Vacuum Gauge,
  • Brass Tee Fitting,
  • 2-1/4” M NPT – 1/4” M NPT Fittings,
  • 2 shut-off valves.

Vacuum Hose Kit allows vacuum source to be located away from your machine.

• 10 feet hose length, 5/8” ID-7/8” OD.
• 2 – 5/8” hose barbs.
• 2 – 3/8” F NPT-1/4 M NPT Hex Adaptors.
• Hose Clamp.

• Replaceable Top Plates and Gasket Sheets can be used to drill through workpieces and protect the surface of the Vacuum Chuck.
• Precision ground Replaceable Aluminum Top Plates are available to cover the surface of the Vacuum Chuck.
• Top Plates allow drilling through or machining around the outside of workpieces without damaging the vacuum chuck.
• Several configurations of Top Plates are available to hold unique size workpieces and protect the surface of the Vacuum Chucks.
• The low slip Vacuum Gasket Sheet allows drill through the workpieces without damage to the Vacuum Chuck and provides vacuum seal.

Use a Hex Workstop and Edge Clamp to Securely Hold Various Size Parts, locate parts consistently.

• Adjustable Workstops and Edge Clamps can hold a wide range of height and size workpieces and can eliminate the need for custom fixtures.
• Tightening the flathead screw moves the Edge Clamp toward the workpiece, holding it securely in place.
• Low profile for maximum clearance.
• Reduce set up time and eliminate the need for custom fixtures.
• Numbered locations allow for repeatable set up.
• Black Oxide steel construction.

Side and End Workstops hold parts in place, reduce side pressure, locate parts consistantly.

• Side and End Workstops locate the workpiece consistently.
• Securely holds parts in place, minimizes workpiece movement if large amount of pressure is applied to the workpiece.
