8″ x 12″ Modular Vacuum Chuck Kits & Air Venturi Vacuum Pump

These Complete Vacuum Workholding Systems Include Everything Needed to Get Started Vacuum Workholding

Vacuum Workholding Systems: Modular Vacuum Chucks & Air Venturi Vacuum

These Complete Vacuum Workholding Systems include a selection of our 8” x 12” Modular Vacuum Chucks, Air Venturi Vacuum Pump, and all the accessories needed to get started vacuum Workholding.

Modular Vacuum Chucks are available in four (4) preconfigured Kits that include 1, 2, 3 or 4 Precision Ground, Aluminum Modular 8″ x 12″ Vacuum Chucks and accessories.

The Modular design of the 8″ x 12″ Vacuum Chucks allow you to connect multiple Vacuum Chuck Pallets to quickly create custom size, and custom vacuum workspaces.

Numbered locations on the face of the Vacuum Chuck allow for quick and repeatable set up and consistent workpiece placement. This easy repeatable workpiece positioning between Vacuum Chuck Pallets is useful for high production; load one Vacuum Chuck off-line while another is being machined.

The Modular Vacuum Chucks fit in a standard size milling vise, or attach the Vise Block to hold in milling vise opening as small as 5”. Or, hold parts on a magnetic chuck using the Steel Vise Block.

Only one Air Venturi Vacuum Pump is required for multiple connected Vacuum Chucks.

The 1/4″ NPT Air Venturi Vacuum Generator Pump included in these Complete Systems creates a vacuum using compressed air. Simply attach your shop air to the Air Ventur Vacuum to create the vacuum for the Vacuum Chuck.

The straight through filter free design of the Air Venturi Vacuum helps prevent clogging from debris or contaminants.

Complete Details:

Complete Modular Vacuum Chuck & Air Venturi Vacuum Pump System

  • These Complete Systems includes choice of Modular Vacuum Chuck Kit with either one, two, three or four Modular Vacuum Chucks, Air Venturi Vacuum Generator Pump as 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.
  • The included 1/4″ NPT Air Venturi Vacuum Generator Pump creates a vacuum using compressed air.
  • The Air Venturi Vacuum’s Solid Anodized Aluminum construction allows for use in harsh, dirty environments and clean rooms.
  • Its’ straight through, filter free design helps prevent clogging from debris when machining.
  • The vacuum operates by supplying compressed air to the supply port.
  • When air pressure is applied, the Air Venturi Vacuum creates a vacuum at one end and the air is exhausted out the other end.
  • 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 included 1/4″ NPT Air Venturi Vacuum, based on your application and use, is usually appropriate for up to 4 connected Modular Vacuum Chucks.

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

  • 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.
8" x 12" Modular Vacuum Chucks:
  • 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.
Air Venturi Vacuum Pump:
  • The 1/4″ NPT Air Venturi Vacuum Generator Pump creates a vacuum using compressed air.
  • The Air Venturi Vacuum’s Solid Anodized Aluminum construction allows for use in harsh, dirty environments and clean rooms.
  • Its’ straight through, filter free design helps prevent clogging from debris when machining.
  • The vacuum operates by supplying compressed air to the supply port.
  • When air pressure is applied, the Air Venturi Vacuum 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

 

Hold Down Force / Workholding / Fixturing Calculations for Air Venturi Vacuums

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

Remember to allow for a safety factor.

The typical supply air consumption rates and vacuum flow rates are listed in the tables below.
