What you should know about 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 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.
