ALUFIX PRINCIPLE ALUFIX principle Through holes on all surfaces, thereby connecting possibilities on all six sides. Basic design Origin of element geometry All further dimensions arise by multiplying the initial cube. Initial shape: Cube Marking for holes on all surfaces Through holes on all surfaces Sectional view

ALUFIX PRINCIPLE ALUFIX element geometry guarantees that the grid in all directions across any number of joins will remain unchanged. Hollow profiles (Light bars) are a logical extension for larger cross sections and lengths. Couplings mounted at both ends create 6 sided connection option. Connection technology Each hole is not only for positioning but also for fixation Twin bolt for positioning Lock and twin bolt Nubs are space saving connection solution for slides, quick couplings and contour blocks.

8 ALUFIX MODULAR CLAMPING SYSTEMS Simple part supports - simple, direct and without design, built according to the Alufix principle. Here a modular fixturing system with a large range of components comes into its own. Fixtures - According to design and requirements of workpiece data, concept for repeatable use - From checking of purchase parts to series measuring Sophisticated part supports - With measuring, checking and adjusting elements, i.e. dial gauges, retractable plug gauges, moving slides Gap and flush gauges - with folding/removable contour stripe models and or measuring equipment

ALUFIX MODULAR CLAMPING SYSTEMS Meisterbocks - Outer and inner for front, decklid, floor or complete body-in-white Fuegemeisterbocks (Match metal fixtures) - For front, rear, floor, sidepanels and a complete chassis Cubings - For supporting reference models and single parts in changeover Frames for design models - For supporting Uriol and clay models ALUFIX fixtures can also be used for assembly and alignment, glueing and welding, milling and laser machini
