Duplex Milling Services
What is Duplex Milling, aka Twin Milling?
Duplex milling, also known as twin milling, provides a cost-effective alternative to in-house fly cutting, face milling and grinding. This process is used in applications requiring flat, square and parallel tolerances to 0.001”.
Duplex mills use opposed shell mills, mounted on a pair of horizontal spindles, to efficiently remove stock to meet tolerance requirements on opposing planes. Requiring just one setup for multiple parts, milling two sides at once is the most cost-effective way of producing high-quality aluminum and stainless steel machine-ready blanks.
What are the Benefits of Duplex Milling, or Twin Milling?
Other benefits that duplex milling, or twin milling, provides includes a reduction of internal stress in many metals. This milling process removes equal amounts of stock from both sides of a blank in tandem motion. By reducing stress, the stability of a machine-ready blank is improved for additional machining phases.
There is also great versatility in the way blanks can be configured for machining: they can be stacked in multiples and then duplex milled, thus adding greater cost efficiencies through reduced machining time.
