Rafter Equipment Corporation has shipped a new RT-3000 “tube mill re-top” and drive train upgrade for a major North American automotive tube producer. The equipment will replace older McKay tube mill equipment that is worn, difficult to maintain, and has outlived its useful life.
The McKay machine had integral roll stands and gearboxes (see below) making them difficult to maintain and upgrade the drive train. By switching to conventional universal-shaft driven roll stands, the drive traincan be tailored to the customer’s needs. In this case, the addition of a 4-speed transmission allows for both high-torque on the more difficult products and high-speed on the easier products. The customer’s existing mill drive system and motors will be utilized.
