Gantry milling machine producing wind turbine parts, and more High-power and high-precision functions respond to need for throughput and product quality

Ingersoll Machine Tools, Inc. has started manufacturing components on its new gantry milling machine, the Ingersoll MasterMill. The new installation was designed and built by Ingersoll, using its own components and controls, and adds "significant" (though undetailed) capacity to the company’s Ingersoll’s Contract Machining and Manufacturing business.

Rockford, Ill.-based Ingersoll Machine Tools, Inc. supplies large machine tools and automated fiber-placement equipment for metal cutting and composite manufacturing, and handles sub-contract and engineering services for other manufacturers.

To date, the MasterMill machine has produced large components for U.S. manufacturers of wind energy machinery, and transportation systems, mining equipment, nuclear power plant systems, and gas turbines. It also manufactures structural components for Ingersoll machines.

The size and flexibility of the new MasterMill allow Ingersoll to produce parts for various applications. The machine has an adjustable crossrail and is over 26-feet wide between the columns, meaning it is able to produce parts up to 26 ft. W X 100 ft. L X 21 ft. H. The workzone includes a 16 ft. diameter turning and milling table, adding to the range of capabilities. Automatic, quick-change functionality for both the spindle units and the cutting tools establishes the a high level of automation that increases productivity: The MasterMill can perform multiple machining operations such as, milling, turning and boring.

According to the builder, high-power and high-precision features were engineered into the MasterMill in order to accommodate customers’ demands for throughput and product quality. With a 125-kW main spindle drive and employing a Siemens 840D for controls, Ingersoll meets those customer requirements.

Also supporting quality and safety needs is the machine’s remote-monitoring functionality; managers and application engineers can view real-time manufacturing progress from their desktop computers. And, the MasterMill is located in a climate-controlled room that has access for large part delivery and pick-up.

Ingersoll added that it will continue to invest in its U.S. manufacturing capabilities.
