A MIKSCH MTC-350 Automatic Tool Changer was sent to us because it was no longer functioning properly. After Inspection and cleaning, the cam gear was found to be worn, which was effecting the operation of the machine. It was also found that the ATC motor had a short in it, and needed to be rewound for it to run again. Our staff of skilled technicians have repaired many of these automatic tool changers, and are able to properly diagnose, repair and fine tune these machines, so they run well and continue to for years.
