Modular precision and systematic flexibility ALUFIX from Witte is the worldwide proven clamping and fixturing system for reproducible workpiece fixtures in dimensional measurement and manufacturing technology. Made of high-quality aluminium, depending on the product variant (ECO - medium-strength or Classic high-strength) ALUFIX guarantees the best material quality, durability and resilience. Reproducible and retoolable Fixtures implemented using ALUFIX can be reliably assembled. Consistent implementation of the modular system allows unlimited, long-term multiple use of practically all standard...

The ALUFIX principle: ingenious from the base up Six sides, eight corners, twelve edges: the starting shape and basic element of the ALUFIX system geometry is the cube. All other element configurations are created by multiplying this basic shape - with through bores on all surfaces creating connection options on all sides. Each hole is suitable for both positioning and fixing. Connection technology The ALUFIX element geometry ensures that the grid is precisely maintained in all directions and across any number of joins. • crosspiece nut to screw in . Creation of the ALUFIX element geometry •...

Base plates Alufix base plates The proven base for multiple fixtures ALUFIX base plates are mainly used for small and medium sized fixtures. The plates are rigid, precise and offer the greatest freedom in assembly, as the entire surface can be used - in contrast to frame type fixtures construction made of profiles, which are suitable for larger structures. ALUFIX base plates are available in two versions: ALUFIX Classic base plates with mounting holes on all 6 sides. ALUFIX grid base plates with mounting holes only on the surface, in Eco design. ALUFIX Classic base plate: The dimensions: precise...
