Duplex Milling

Duplex Milling is the most cost effective way to produce high quality square-corner blanks. Duplex Milling provides blanks with squareness and parallelism tolerance to .0002" and reduces premachining costs up to 50%. To achieve such a close tolerance, blanks ready for Duplex Milling are clamped in place with two sides exposed for milling. Then, opposing cutters run the length of the material removing equal amounts of material from each side. Premachining costs are reduced by milling two sides of the blank simultaneously. This combination of accuracy and speed provides a blank with superior tolerances, squareness, parallelism, and surface finish (up to 16 Ra) at significantly lower costs.

High Quality Blanks…High Quality Parts…Lower End Costs

Parallelism is critical to maintaining part squareness during machining. Machining Duplex milled blanks, with parallelism and squareness to .0002", allows you to maintain your high quality machining standards without wasting time and money squaring-up blanks on your CNC machines.

Efficiency = Lower Premachining Costs and Shorter Turnaround

Multiple blanks can be stacked and Duplex Milled for greater premachining efficiency. Duplex milling stacked blanks significantly reduces premachining costs and turnaround time. Plus, part-to-part tolerances are consistent. To generate additional savings, multiple blanks can be Duplex Milled in over-sized lengths and cut-to-size once milling is completed…generating several parts from one Duplex Milled part…saving more time and money.

18 Duplex mills combine accuracy and speed to provide low cost square corner blanks with superior tolerances, squareness, parallelism, and surface finish. Milling multiple parts simultaneously reduces machining costs by up to 60%.
