ABSTRACT:
In a thermal equalization system a machine tool carriage preferably of aluminum but which could be made of other lightweight materials, a drilling spindle housing is mounted on the carriage. At least one spindle housing is be mounted said carriage to service work pieces mounted on a tooling plate of the work table for said spindle. The chiller unit is used to provide coolant to the spindle to compensate for the heat generated by the spindle during drilling. When the spindle is not drilling, excessive cooling of the spindle can result. Accordingly, the instant invention also includes, a conductive rubber heating pad which is attached to the spindle structure to provide a heat source for the system to compensate for excessive cooling when the drill is not generating heat. The temperature control maintains the temperature between the spindle housing, carriage and work table thereby minimizing temperature expansion differentials between the drilling position and the worktable position.
