The KRD 400 is a powerful roll groove dressing machine designed by Herkules. It has been developed based on the successful machine concept of previous years. The roll stands of a stretch-reducing seamless tube mill are accommodated by the machine, then positioned and measured. The rolling rings are machined in a fully automated fashion. The machine can be designed for roll stands with one central or three individual drives.
An automated roll stand infeed with RFID stand identification allows for a fully automated machining operation.
