Turned tool changing station SK11 and SK20
5/ 27 April 2019
1General information
1.1 Intended use
The SK11 and SK20 turned tool changing stations are space-saving tool storage units with tool
slots arranged in a circle. The SK11 turned tool changing station is designed to hold and
temporarily store up to 12 milling and/or machining tools with SK11 tool holding fixtures. The SK20
changing station can accommodate up to 14 milling and/or machining tools. After actuation by the
operator, the automatic tool release takes place from a freely selected storage slot. Please refer to
the technical data for more precise features of the tools. The control of the changing station takes
place by means of the TCHUni.dll file offered by ISEL. The changing station has internal power
electronics and offers the possibility of connecting external components to an I/O interface.
General information:
Carefully read the entire assembly manual and follow the instructions. Non-observance of this
assembly manual can result in property damage, severe bodily injury, or death.
All important information about the assembly, programming, and operation of your SK11 or SK20
turned tool changing station can be found in this manual. It also provides you with important
information and notices for your safety.
1.2 Safety instructions
The SK11 and SK20 turned tool changing stations are designed
according to the state of the art and generally recognised good
engineering principles.
The equipment may only be operated in technically fault-free
condition. Faults must be rectified immediately. Children and
untrained persons may not commission the equipment.
The equipment may only be used for the intended purpose:
Changing station for milling tools with SK11 holding fixture for
SK11 turned tool changing station and SK20 holding fixture for
SK20 turned tool changing station. Control takes place by means
of the TCHUni.dll file offered by ISEL.
Do not reach into the turned tool changing station as long as the
machine is switched on and the compressed air is connected.
Prevent fires which can occur due to excessively hot tools in the
turned tool changing station.

Connection to compressed air supply
The turned tool changer requires an operating pressure of 8 bar and must be connected to
a maintenance unit. Required hose diameter 6mm.
4Assembly and commissioning
4.1 Assembly of turned tool changing station SK11, SK20
Ensure that you have a stable and secure foundation for the turned tool changing
station prior to commissioning. Avoid collision with other components of the
machine.
4.1.1 SK11 assembly
Figure 2: SK11 fastening
Fasten all five fastening points on the turned changer to the
mounting area of your machine with machine screws (not included
in the scope of supply) and ensure that it is flat and level.
Attention: The turned changer must be positioned in the
travel range of your CNC machine.
