Function
The 7797 consists of a welded base frame and a rotary table with eight stations including trays for brake discs up to 460 mm in diameter. The machine is fully covered, including dust removal, pneumatic pre-cleaning station, and complete electrical equipment with all drives, controls, and displays for the automatic machining process. The operating panel is integrated and has various data interfaces. The cycle time has been optimized for maximum coating application, with a cycle time of 60 seconds each for priming and coating forward and backward.
The force-controlled rolling process is synchronized on both sides, including real-time monitoring with archiving of process data. Both fully automatic operation and manual loading are possible. Loading and unloading takes place in parallel with the machining process. The rolling unit has two exchangeable cassettes in pliers principle and sensors for monitoring the rolling forces. The force is hydraulically controlled. A pick-up spindle lifts the discs out of the tray.
