Tightening Modules for Automatic Screw Tightening Machines

Tightening Modules for Automation: Mounting Screw Tightening on a Robot Arm or XY Table

The products on this page are the part of an automatic screw tightening machine that actually tightens the screws: the tightening spindles and tightening modules. They do not include a machine enclosure or positioning mechanism; instead, they are designed to mount on an XY table, indexing table, SCARA or 6-axis robot arm. The host controller specifies when to tighten and to what condition, and the results are reported back.

When adding automatic tightening to an existing production line, this is usually more cost-effective than buying a complete machine: if the positioning mechanism is already in place, adding a tightening module and screw feeder creates an automatic tightening station. When models change later, only the coordinates and tightening programs need to be updated, not the mechanism.

The three products divide the work as follows: PRO-FUSE handles micro and precision screws (S0.6~M3.0, 10~700 mN·m); AFC3000 handles medium to high torque with centralized multi-axis management (0.2~5000 N·m, up to 32 spindles per controller); and PRO-Z DK is a patented module that, beyond tightening, also brings the pressing speed and pressure of the vertical Z axis under synchronized control.
