Heatable vacuum clamping plate | high-contour vacuum clamping technology

Bis 200 ° C The new microporous vacuum chuck from Witte heat up. This makes the clamping plate particularly suitable for complex high-tech tasks. The Quadrovac vacuum clamping technology can also be used to clamp workpieces with a complex contour. You can find these and other new products below:

Vacuum clamping plate that can be heated up to 200 °C

15.12.2021 | The core of the new microporous vacuum clamping plate from Witte is a new heating rod solution and a sophisticated programmable controller. Another innovative feature is the free and independent assignment of plate segments with different suction forces and temperatures. This flexibility in connection with an extremely harmonious temperature profile of the surfaces recommend the new vacuum clamping plates especially for use in high-tech applications. Such are, for example, the printing of RFID foils or the measurement under the influence of temperature, for example of carrier layers for flexible displays of mobile phones.

High vacuum, ultra high vacuum and extremely high vacuum

Microporous vacuum clamping plates allow a absolutely level clamping or holding the test part. thin Materials are not attracted to them by suction holes, suction grooves, etc. This means there is no risk of deformation. Especially in the Automation the low weight and the precision of the microporous vacuum clamping plate are advantageous.

The pressure distribution in the special structure of the vacuum clamping plate enables even carrying capacity, even if the surface is only partially covered. This means that workpieces of different sizes can also be fixed on the same clamping plate. 

The new aluminum plates, which can be heated up to 200 degrees Celsius and have integrated microporous surfaces, are continuously being developed by Witte individuallyen customer specifications and application purposes designed and manufactured.

Vacuum clamping technology for workpieces with complex contours

02.12.2020 | Witte has a new one Vacuum clamping technology developed, which was specially designed for clamping workpieces with a complex contour. Such must be machined in many axes. Quadrovac is the name of the new development that can clamp such strongly contoured parts. the Workholding is suitable for machining during milling, drilling and thread cutting.

Small to medium sized parts from Plastic, wood, glass or metal such as cast parts can be clamped using the new clamping technology. They can have steps, pockets or openings.

The vacuum clamping technology Quadrovac consists of a modular, combinable Vacuum plate in different formats. For example, a vacuum plate with the dimensions 300 x 450 mm holds clamping elements in a grid of 150 x 150 mm. This is done individually and based on the shape of the workpiece that is to be fixed.

Vacuum clamping technology with flexible elements

Be available Elements with a flat clamping surface or to cover unneeded base plate areas. There are also elements that can be milled to the desired height by the user or those that are equipped with variable molded sealing elements. The latter offer unprecedented flexibility for clamping small and medium-sized workpieces in five-sided machining.

The elements of the new vacuum technology are in a grid of 30 x 30 mm with a total of 25 shaped sealing elements, so-called Pods, equipped. They form the contact point to the component through which it is sucked in and clamped. Pods that are not required for the component geometry can be unscrewed and are available for other applications.

The individually equipped 30 x 30 mm grid allows the inclusion of workpieces with closely spaced bores and openings and those with a correspondingly large diameter. Thanks to the pod height of 25 mm, the working depth is comfortable. Quadrovac also allows the side machining of clamped workpieces.

With his Freedom of configuration the vacuum clamping system is suitable for fixing and clamping workpieces in series processing and for holding frequently changing part shapes.

Black microporous chipboard for a reflection-free measurement

02.08.2019/XNUMX/XNUMX | As the world's first provider, Witte Barskamp not reflectivee microporous vacuum clamping plates made of black Metapor material on the market. The new plate variants were specifically designed for use in the Measurement Technology developed in which optical reflections have often been a problem up to now, such as when testing transparent RFID foils, wafers or foils.

The microporous Metapor vacuum clamping plate from Witte enables absolutely level clamping and holding of the test part. thin materials are not attracted to them by suction holes, suction grooves, etc., which eliminates the risk of deformation. The low weight and precision of the microporous plates also score points, especially in automated processes.

The pressure distribution in the special Metapor structure enables uniform load-bearing capacities, even if the surface is only partially covered. This means that workpieces of different sizes can also be fixed on the same plate. Likewise, the porous surface can be divided into separately switchable areas and these can be individually subjected to vacuum. The plates can be heated up to 100 °C and also cooled, each provided with a corresponding control. The clamping plates are available in individual geometries.
