Clamping Fixtures

A magnetic drill's holding force depends on two conditions: ferromagnetic material of sufficient thickness, and a clean, flat contact face. If either is missing, the magnet is not the answer. On stainless steel, aluminium and cast iron, magnetic adhesion is either absent or far below nominal; on curved surfaces such as pipe, the contact area is small to begin with. The BDS clamping range fills exactly that gap. Vacuum clamping devices use a Ø 300 mm plate to hold the machine by negative pressure on non-magnetic but smooth surfaces, and the manual-pump model does it without any electrical supply. MABZAV400 is defined for smooth surfaces only and should not be used on painted, rusted or textured faces. On pipe, the clamp follows the machine: MABZRO250 with MAB 100 for Ø 80–250 mm, MABZRO1300 with MAB 1300 for Ø 150–500 mm, and the MABZRO500 chain with MAB 825, MAB 845 and MABasic bodies. The magnetic column and the industrial drill stand turn an ordinary commercial hand drill into a fixed, repeatable drilling setup, and the prism vice for the stand holds cylindrical parts such as pipe and section on axis. The Mobilclamp covers mobile applications, and the collared hex nut is included as a fixing element. The selection rule is simple: first ask whether the surface is magnetic, then whether it is flat or curved.
