CNC vacuume table or vacuum chuck for vacuum workholding of small flat parts and sheet material for milling applications on DATRON high speed CNC machining centers

Vacuum Table for CNC Mills

 

Vacuum table workholding for flat & thin workpieces. The DATRON Vacuum Table is designed to swiftly and efficiently secure flat workpieces to the bed of a machining system. Thin stock, which could be secured only with great difficulties before, is now secured literally within seconds. Quickly secure plastic foils as thin as 0.001”, to 0.250” large aluminum sheets. This vacuum table features airflow-optimized ports, with recessed chambers, to provide superior vacuum distribution. A low cost, gas-permeable substrate serves as a sacrificial vacuum diffuser, allowing the cutter to machine through the workpiece, without cutting into the table.

 

DATRON Vacuum Table Benefits:

 

 

Most CNC manufacturers just don’t get involved in workholding. They sell you their machine and let you find a way to hold your parts once it arrives. Well, DATRON takes a more holistic approach and considers workholding part of the overall solution. Thanks to superior German engineering, when your DATRON milling machine arrives, you’re ready to cut parts and make the chips fly! Designed for efficiency in set up and job change over, our user-friendly, modular solutions work synergistically with the blazing speed of our high-speed milling machines — delivering the industry’s fastest cycle times.

 

Made Specifically for DATRON High Speed Milling Machines

 

We’ll be honest, the high-speed and low-force of DATRON spindles made the job of innovating Set Up fairly easy (at least for the clever DATRON engineers in Germany).

 

That’s because low force means that a vacuum can be used to hold fixturing and blanks — something not possible with a conventional CNC. What’s resulted is a “modular” workholding design that allows for multiple setups on the bed. One station or segment may be a vacuum table (vacuum chuck), another manual pallet changer, and a third a pneumatic clamping system. This variety of segments provides the agility to adapt to job changes.

Centering inserts on the bottom of each segment register with conical cavities (milled by the machine itself) on the surface of the machining table. This results in a “boss-in-cavity” system that insures location repeatability. So if you’re in the middle of a batch and an unexpected rush project comes in, just remove one pallet and replace it with the new job. When the rush job is complete, return the first pallet to its place and pick up where you left off.

The ability to quickly adapt to changing needs is the essence of agility ... and agility is the very thing that gives a manufacturer the competitive edge.

More About DATRON Vacuum Tables

 

The Quadramate consists of four 12” x 18” x ¾” vacuum chuck segments secured to a 5/8” aluminum sub-plate that can be secured to the machining table by either screws or vacuum. The four combined chucks have over five thousand micro holes drilled, with a slight counter-bore or cup to distribute the vacuum to a broader area. This system fits on M8 and larger machines and is ideal for batch machining or milling larger parts from sheet material.

When to go “DH”. The Dense Hole Pattern option was engineered specifically to hold extremely small parts that exhibit minimal surface area. The individual cups and air holes on the vacuum table are in closer proximity to one another to insure that maximum suction occurs directly beneath the workpiece. Parts with larger surface areas do not require DH models or our larger pumps.
