TopPos Positioning System The TopPos Concept Novel positioning system for workpiece contact points. Accurate and repeatable without dedicated, machined contours. 100% catalogue items for fast fixture building and adaptation. Conventional part contact point: Previous method with modular elements in grid: Positioning a column or console in a rough grid of i.e. 40mm. The required intermediate positions are achieved within the profile cross section (2x/3x grid) and by using an individual contour block (possibly with an angled surface). Each contour block has to be designed, dimensioned,...

TopPos Positioning System TopPos part contact point: New design with TopPos elements: Replaces up to 90% of individual contour blocks with a few standard elements - Positioning in grid of 1mm or 0,5° respectively = max. 0,5mm/0,25° deviation (optional 0,5mm grid possible) - Precise alignment with 0,05mm shims, +/- 2mm range - Linear components have 10mm, rotary components have 10° steps - Actual grid achieved by a combination using differential steps (plus or minus 1) - Profile lengths in steps of 40,10 or 1mm - Profile size 80x80 (50x50 in preparation) - Manufacturing process: Cut/mill...

Profiles Lengths from 40 to 3000mm, the last four digits of item number correspond to profile lengths in mm - Cross section 80x80 - Steps in length: 40-1000mm in mm steps >1000mm in 40mm steps - Serrated slots, advantage: Rigid profile due to low slot depth - 4 core holes for M8 spaced at 40mm - 4 outer core holes for M6/M8 for face end connection - Material Alu-F28 - Only approx 20% of conventional profile tolerance due to precision extrusion
