“We also cannot explain why nobody has ever invented the modular screw jack until now”, states Manuel Nau, the Sales Manager at Andreas Maier GmbH & Co. KG. And so it is the Fellbach experts for clamping on the machine table who have been the first to bring this clever solution onto the market. AMF presents a flexible, modular screw jack. Various elements can be assembled securely up to the required height in order to fix large and medium-sized components in T-slots and grid plates. The burnished modules made of tempered steel are reliably connected with a threaded ring and allow great flexibility during assembly.

The modules are inserted into T-slots and on grid plates by means of screwed-in base elements. At the top of the vice, a spindle with a trapezoidal thread ensures that it is adapted to the workpiece.

A starter kit for a wide range of applications

The manufacturer covers a wide range of applications with a starter kit consisting of ten parts. This includes a screw jack element with a base element, a small and medium spacer element, three M16, M20, M24 thread adapters, three T-nuts for groove 18, 22, 28 as well as an insertion tool. Additional intermediate elements make heights of up to a maximum of 1620 millimetres possible. The permissible supporting force is 60 kN. In addition to this, AMF offers a further support element with a fine thread. The user can adjust this precisely up to a maximum support height of 330 mm under load. Optionally attachable spherical, smooth or selective supports compensate for any unevenness of the workpiece. They are held magnetically, secured with a cylinder pin and can be adjusted with an angle of +/- 3°. The support element can be used in horizontal and vertical clamping.

Practical, easy to use and awarded a prize

If T-slots or grids do not fit, base elements can help. They enable variable positioning on the machine table. A workshop trolley with mountings for the modules ensures order and mobile, quick provision at the place of use. The new modular screw jacks from AMF make a solid and well thought-out impression. They feature impressively high manufacturing quality, flexible application options and improved handling compared to large and heavy elements, which always require a crane. Anyone who sees it for the first time is amazed why it has never existed before. For the Design Center Baden-Württemberg, this is even worth the Focus Open Design Prize 2020 in gold.
