Witte Vacuum Workholding Products

Witte Vacuum Systems & Pumps

Vac Mat Systems

Specially molded plastic mats create a modular, universal workholding fixture for precision milling. Each vac mat system measures 200 x 300 mm and works best for parts larger than 150 x 150 mm. Larger configurations are possible.

Aluminum Flip Pod Vacuum Systems

Aluminum flip pod workholding systems are designed to secure large work pieces on big machines. These configurable vacuum holding systems work well for most machine types and sizes and help minimize setup changeover times.

Witte CNC Vacuum Pumps

We offer dry, air-cooled, and oil-lubricated vacuum pumps with capacities from 3 CFM to 500 CFM. Special units are also available for larger workholding applications.

Round Grid Type Vacuum Chucks

Achieve high holding force with round grid-type vacuum fixtures. The universal design replaces many dedicated vacuum chucks and allows clamping of smooth or rough materials. Available in sizes up to over 800 mm in diameter and special sizes and configurations.

Witte CNC Vacuum Pump Features

The specific capabilities of each Witte vacuum system vary by the pump type or model. Pumps range in capacity from small handheld models to entire vacuum workstations. Some advantages of Witte vacuum pumps include but are not limited to:

• Reliable in continuous operation 
• Easy to maintain
• Modular unit has integrated liquid separator
• Space saving assembly for easy access
• Integrated air filter, safety valve
• Pumps from 5m3/h to over 500m3/h, also on request dry running pumps

Witte Vacuum Chucks

Small Parts Vacuum Chucks

These chucks are constructed of aluminum and feature a slotted base and special adapter pads for securing small parts for light milling and drilling. Small part vacuum chucks also secure pieces larger than 25 x 25 mm for fine milling and engraving applications.

High Precision Micro Porous Chucks

Micro porous chucks are constructed of ceramic, Metapor, porous aluminum, and sintered bronze and are designed to clamp thin workpieces with high accuracy. These chucks are best suited for the light, dry processing of foils, films, paper, and thin metal strips.

High Precision Grid Type Chucks

This high precision grid type chuck style offers the strongest and most accurate method of workholding. We offer rectangular styles for milling and grinding, and circular styles for CNC lathes.

Ice-Vice Freeze Chucks

Designed for small or intricate work pieces, freeze chucks provide incredible holding accuracy without inducing stress on the part. Use Witte Ice-Vice Freeze chuck systems in R&D laboratories or high-volume manufacturing of electronics, optics, and medical devices.

Witte Vacuum Specials

We offer a range of Witte vacuum products for specialty applications. Options include 3D chucks for aerospace, custom vacuum chucks, friction-stir welding chucks, and semiconductor and wafer chucks for inspection systems. We’ll help you find a custom vacuum workholding solution for your application.
