Visit us at http://www.theturretguy.com/ and you will find out that we bore out the worn station and insert a hardened steel sleeve, thus ensuring an Amada OEM tolerance. The process also allows for the sleeve to be replaceable in the future. This sleeving process is accomplished without removing the turret disk on most machines. The work is done on-site, at the customer's convenience, thus minimizing down time. A complete turret restoration usually takes only 2-3 days.
