Vacuum Clamping Devices for CNC Machining

Schmalz clamping systems are used in CNC machining centers to ensure that the workpieces being machined are held securely. The clamps are installed quickly and easily and they are predominantly used in the woodworking industry. Next to wood, Schmalz clamping devices are excellently suitable for workholding in metal, plastics, glass, aerospace, solar and electronics industries.

Vacuum clamping is economically profitable because of short set-up times and because it allows you to machine workpieces on all sides. Individual suction plates can be removed and reinstalled easily without having to replace the entire product. The clamping systems from Schmalz can be installed in new machines as well as they can be used to modernize existing machining centers. Schmalz has the perfect solution for every application and guarantees optimal process reliability with all of their devices.

Schmalz offers a wide range of clamping systems. You can easily order vacuum blocks along with all accessories and spare parts from our online shop:

Vacuum clamping systems

Vacuum Woodworking Clamps

Grid table clamping systems are perfectly suited for complex five-axis machining. The vacuum blocks can be fastened directly to the grid table or by using mini-plates and adapters and yet be moved easily. The positive locking between grid table and the particular fastener used ensures optimal workholding even under the highest machinging forces.

Schmalz also offers flexible clamping solutions for smooth machining tables. With these solutions, the vacuum blocks can be moved to any location across the entire work surface. Two separate vacuum lines are employed to clamp the suction cup to the table while also clamping the workpiece. The same principle is used by the Innospann smooth table suction blocks to which suction cups are attached.

For smooth aluminum tables, Schmalz offers a hose-free vacuum clamping system with an integrated vacuum line. With these tables, the vacuum blocks can be positioned in any location and both the workpiece and the vacuum block are held in place by the suction from the vacuum line.

You can also find various suction cups and Adapter-Plates for console table systems. These products are available for Schmalz console tables as well as for tables from manufacturers like Biesse, Morbidelli and more. Schmalz specially designed these products to fit consoles from these manufacturers used in CNC machining centers. The suction cups can be positioned and fastened to the consoles either manually or per vacuum.

Types of clamps

Next to vacuum clamps, the Schmalz portfolio also includes mechanical clamps for all types of workbenches, making Schmalz clamping systems even more flexible.

Retrofitting of CNC Machining Centers with Steel-Plate

Schmalz vacuum clamping systems can be retrofitted to any existing CNC machining center, making them a cost-effective alternative to investing in a new machine. Independently from manufacturer or type of machine: Schmalz has the perfect solution for every workbench.

On smooth benches, you first install a grid table to which the Innospann Steel-Plate is then attached. A sealing gasket inserted in the grid table seals off the hollow spaces between the two plates. Sealing magnets or solenoid valves close the openings on the Steel-Plate that are not in use. The suction cups can be placed either directly on the Steel-Plate or on a Quad-Base.

Vacuum Clamping for Manual Machining

The vacuum clamping system Multi-Clamp is specially designed for manual machining and replaces the classic bench vice. The Multi-Clamp leaves no marks or indentations on the clamped surface, leaving the workpiece unblemished. The continuously rotatable suction plate lets you work on all sides, making it unnecessary to reclamp the workpiece. The suction plate is attached to the turn/swivel fixture Multi-Base, which can be attached to virtually any surface using screws or suction.

Clamping Systems for Metal and Plastic Processing

Schmalz offers the Matrix-Plate for clamping flat and easily deformed materials such as aluminum. A sealing gasket is used to seal off the area on the plate where the workpiece is placed. The integrated vacuum connection is used to clamp the workpiece. Optional friction pads provide the highest possible holding forces to ensure reliable clamping.

The Matrix-Plate can be expanded with the Innospann Steel-Plate. The vacuum blocks can then be positioned anywhere on the Steel-Plate, thereby completing the clamping system.

Clamping Solutions for Glass Processing

Innovative solutions for glass processing: vacuum blocks equipped with special friction plates ensure that the workpieces are securely held on flat tables. The suction cups are designed for either the Quad-Base or for a special quick-change system from Schmalz. In both cases, the suction cups can be easily placed in the desired locations, which is all it takes to adjust the system to any shape of workpiece.

Clamping Equipment for 3D Freeform Surfaces

Schmalz 3D clamping systems allow to securely workhold complex parts and workpieces. The suction cups of the Basic Holding Fixture system allow for rotary and height adjustment. Thus, even curved and uneven surfaces can be easily clamped, providing a secure hold during CNC machining.

A ball joint and a star grip are used to adjust the angle and the height of the suction cup while two clamping levers are used to lock it in place. In combination with the Schmalz Steel-Plate, the Schmalz 3D clamping system can be easily installed on any type of table.
