Description
The SPVPL MA is a modular vacuum plate with high holding force made from cast aluminium. The workpiece stops provide great flexibility in positioning the workpiece to be machined. Adapter mats are required for milling through openings. Optional grid table suction blocks can be mounted; they offer maximum flexibility when producing apertures.
The SPVPL MAR is made of cast aluminium like the MA version, but has additional friction pads. These increase the horizontal holding forces by up to 30% compared with a vacuum plate without friction pads, allowing higher cutting forces and feed rates.
The friction pads exert no additional force on the workpiece, are resistant to oil and ozone and can be replaced individually when worn. They are activated and deactivated automatically via the vacuum supply.
The grid is selected according to the workpiece: for geometrically simple workpieces with few webs and apertures (web width > 30 mm), a 25 × 25 mm grid is recommended; for complex workpieces with many webs and apertures (web width < 30 mm), a 12.5 × 12.5 mm grid. Openings in complex workpieces are additionally sealed with a sealing cord, which can be laid close to the apertures with a fine grid, minimising losses of clamping force.
With grid table suction blocks, apertures can be machined: the workpiece is first machined on the vacuum plate, then the suction blocks are placed directly in the grid of the plate according to the position of the holes, so the workpiece can be drilled through without damaging the vacuum plate or the component.
Scope of delivery: vacuum plate, fixed stops, hose connection, locking screw, sealing rubber cord; the MAR version also includes friction pads. Material: high-strength aluminium. Available with precision-milled functional surfaces (parallelism 0.01/100 mm) or ground functional surfaces (parallelism 0.007/100 mm).
The vacuum plate can be secured quickly on the machine table with clamping claws or a zero-point clamping system.
Advantages
- Modular system with maximum flexibility
- Holes and apertures by means of grid table suction blocks
- MAR: up to 30% higher horizontal holding force for maximum cutting force and higher feed rates
- Friction pads resistant to oil and ozone and individually replaceable

For combination with the grid table suction blocks, this version needs two vacuum connections. * Also available with 5 × 5 mm slot dimensions for combining the vacuum plate with grid table suction blocks for machining apertures. Order numbers refer to the version with precision-milled functional surfaces (parallelism 0.01/100 mm). Version with ground functional surfaces (parallelism 0.007/100 mm): order number with the suffix -GS, e.g. B900500127-GS.
