3.1 Functional description
ƒ
The S-Former E is an electrically powered tapping unit head.
ƒ
It has been designed for the non-machining manufacture of internal threads through tapping or
thread grooving.
ƒ
The S-Former E consists of an AC Servodrive, belt drive, pneumatic cylinder, pneumatic valve
(not pictured), position sensor and spindle.
ƒ
The AC Servodrive rotates the spindle in which the tool is fixed, while the pneumatic cylinder moves
it axially.
ƒ
The position sensor mounted on the cylinder determines the position of the spindle and feeds it
back as an analogue 0...10V signal.
ƒ
The valve for retracting and extending the pneumatic cylinder can be controlled via digital signals.

In principle, machining operations other than tapping may also be carried out, e.g. thread cutting, drilling,
screw mounting (also torque-controlled), torque tests for mounted elements etc.
The S-Former E can be used for practically all applications for which rotational and free axial movements
are required. However, it is not suitable for applications that require the spindle to be moved in an axial
direction via a defined feed rate.
3.2 S-Former E control unit
Before operating the S-Former E, it must be combined with a control unit featuring a frequency converter
and servo control technology for controlling the AC Servodrive.
Using a correctly designed and programmed control unit enables all rotation speeds and torques to be
controlled and monitored within the permissible mechanical and electrical limits for each AC Servodrive.
The position sensor enables switching points to be created depending on the feed movement of the
pneumatic cylinder.
