Spreitzer VS vacuum suction unit Set – Flexible Vacuum Clamping Technology for Measurement Applications and Light Machining Tasks
Anyone who wants to secure workpieces quickly, securely, and with minimal warping faces a challenge that is often underestimated: Conventional clamping devices are costly, time-consuming to set up, and often not flexible enough for varying component geometries. Mechanical clamping devices regularly reach their limits, especially with flat, thin workpieces made of metal or plastic, as well as with small components. The VS vacuum suction cup set from Spreitzer offers a straightforward and cost-effective introduction to vacuum clamping technology.
Vacuum and Adhesive Film—How the VS Set Works
The system is based on a combination of vacuum and adhesive film: This combination enables extremely high holding forces when needed, far exceeding what can be achieved with vacuum clamping alone. The cast aluminum vacuum cups can be flexibly positioned on various machine tables and connected to one another, allowing even large workpieces to be secured safely and precisely. For smaller components, each of the four cups can also be used separately.
Ready for immediate use—without an external vacuum pump
A key practical advantage of the set is the included Venturi vacuum generator: It reliably creates the necessary vacuum between the workpiece and the suction cup without requiring an external vacuum pump. This means the set is ready for immediate use and requires no additional infrastructure on the machine table.
What’s Included in the VS Set
The package includes four vacuum suction unit, a Venturi vacuum generator, a sealing cord, an adhesive film, and a vacuum hose.
Two versions—for standard and precision requirements
In terms of manufacturing quality, there are two versions to choose from: Suction cups with precision-milled functional surfaces achieve a parallelism of 0.02/100 mm, while the version with ground functional surfaces achieves 0.007/100 mm. The higher precision grade is particularly suitable for demanding measurement tasks in which the positional accuracy of the workpiece directly affects the measurement result.
Applications of the VS vacuum suction unit Set
The VS vacuum suction unit set is designed for use in measurement and testing applications as well as light machining tasks. Developed and manufactured by Spreitzer in Rottweil, the VS set complements the company’s vacuum clamping technology lineup as a flexible and straightforward entry-level solution for manufacturing companies that do not require complex custom solutions.
Frequently Asked Questions About the VS vacuum suction unit
For which workpieces is the VS vacuum suction unit set suitable?
The VS vacuum suction unit is particularly well-suited for flat and thin workpieces made of metal or plastic that are difficult to secure with conventional clamping devices. Even delicate surfaces that could be damaged by mechanical clamping forces can be clamped gently and securely with the VS set. This requires a sufficiently smooth and level contact surface so that the vacuum and adhesive film can grip effectively.
Can the VS vacuum suction unit set also be used on aluminum and plastic?
Yes—the combination of vacuum and adhesive film works regardless of the material type, as long as the workpiece surface is smooth and clean. This makes the VS Set one of the few clamping solutions suitable for both metallic materials such as aluminum, steel, and brass, as well as plastic parts. For workpieces made of porous materials or with highly textured surfaces, suitability must be verified on a case-by-case basis.
How much holding force does the VS vacuum suction unit Set provide?
The achievable holding force depends on the combination of vacuum pressure and adhesive film. The interaction of these two components enables extremely high holding forces that are significantly greater than those achieved by vacuum clamping alone. The exact value depends on the workpiece geometry, the surface condition, and the set operating pressure of the Venturi vacuum generator.
Is the VS vacuum suction unit Set suitable for measurement applications?
Yes—in particular, the version with ground functional surfaces and a parallelism of 0.007/100 mm is designed to meet the requirements of measurement and testing technology. The precise contact surface ensures that the workpiece is clamped with precise positioning and reproducibility, which is essential for reliable measurement results.
Can multiple vacuum suction unit be combined?
Yes—the four vacuum suction unit Set in the VS set can be connected to one another and positioned flexibly on the machine table. This allows even large workpieces to be securely held in place. At the same time, each cup can be used separately, making the set particularly versatile for varying part sizes and tasks.
