The S-Former Z consists of QQ Guide cartridge 2 Tapping unit head 3 Cardan shaft The S-Former Z is a purely mechanical solution for process-integrated tapping. The linear stroke movement of the press is converted into a rotation movement via a gear rod-sprocket pairing. This is translated in the gear to the required rotation speed and transmitted via a Cardan shaft to the tapping unit head. There, a lead screw rotates equally with the roll tap (equal pitch) and drives it into the part. For the design of the S-Former, information about the process is required. For inquiries, a corresponding...

The S-Former E is an electronic system for process-integrated tapping. The PLC-driven AC Servodrive integrated within the tapping unit head drives the roll tap. The movement of the roll tap to the part is done pneumatically and the tap moves into the material itself as a result of its pitch. For the design of the S-Former, information about the process is required. For inquiries, a corresponding form is available.
