Precision parts manufacturer Coldwater Machine Co. (Coldwater, OH) added to its build-to-print capability a Mitsui Seiki J6CNC jig bore. This machine features components made with extremely tight tolerances and rigidity, enabling it to achieve positioning accuracies of +.00004-in. (1µm). Often referred to as a “mother machine,” Coldwater is using the jig bore to make components for machine tools, as well as for the automotive, aerospace, electronics, and semiconductor industries.
Coldwater recently expanded its facility to 132,500 square feet, helping to provide additional floor space for this machine and other machine tools. This Mitsui Seiki jig bore has a work table size of 50 inches by 30 inches, and longitudinal travel (X-axis) of 40 inches, transversal travel (Y axis) of 30 inches, quill vertical (Q-axis) travel of 11.81 inches, and cross rail vertical (Y-axis) travel of 27.5 inches.
With this investment, Coldwater now has nearly 50 machine tools on its floor for milling, turning, boring, drilling, and grinding. The company is recognized for precision machining of workpieces with complex geometries in a wide variety of materials.
Coldwater can custom-machine metal components to customer print specification or engage its engineering team to assist in design. Producing prototypes, one-offs, and short-run production, the company has extensive experience in precision machining of workpieces with complex geometries in a wide variety of materials.
Coldwater’s material expertise includes tool steel, low carbon steel, stainless steel, aluminum, titanium, Hastelloy, Inconel, and other exotic metal alloys as well as composite and plastic materials in sizes up to 236 inches by 98 inches. Its climate-controlled, state-of-the-art facility is equipped with three 60-foot by 550-foot crane bays and heavy-lifting equipment capable of moving components weighing up to 25 tons. Inspections are performed with advanced CMM and laser tracker equipment.
