The Downholder Adapter for the OTK-3 allows the cutting of light, thin materials as it prevents lifting during the cutting process. Thanks to the spring-mounted automatic height regulation, the Downholder Adapter adjusts optimally to the respective material and its possible irregularities. The installation of the Downholder is remarkably easy: The OTK-3 has to be clamped first into the 43 mm clamping neck of the CNC system before the Downholder Adapter is attached to the OTK-3 from below.
Note: The Downholder Adapter is currently only compatible with the STEPCRAFT D-Series. When using the OTK-3 in connection with the Downholder Adapter on a third party machine is has to be considered that the clamping neck has not to be thicker than 12 mm.
