The material saver, shown to the left, is used as a component within rubber manufacturing equipment. Colonial Machine CNC machined 5 of these products for a client from the rubber industry. We began this project by rough machining the units' product areas per CAD print specifications. Our advanced Technidrill was used to drill the parts' various water passages. We additionally machined pockets for water passage, as well as all holes. Finally, we finish machined all oversize dimensions and machine ends, and ground the material savers' .004"-.005" thick, chrome plating to create a smooth, 63 RMS surface finish.
Using our thermal stress relieving technology, we heat treated the material savers at 1050 degrees Fahrenheit over an 8 hour period. This process helped relieve any stresses in the part, preventing possible long-term product distortions. Holding tolerances as close as ± .001", we manufactured the parts to measure 33" x 11.5" x 7.50". The components also weighed approximately 800 lbs each. With our ISO 9001 calibrated tools and equipment, we evaluated all units to ensure they fulfilled client specifications.
Successfully meeting our customer's high expectations for design and quality, Colonial Machine delivered all final products to our buyer's facility in Omaha, Nebraska within a short, 3 to 4 week lead time.
