Tight-Tolerance Machining
Twin City EDM & MFG delivers advanced CNC 5-Axis milling services for tight-tolerance, complex parts across the medical, aerospace, defense, and industrial sectors. With precision capabilities, we support prototype development and high-volume production with the same level of accuracy and repeatability. Our facility includes vertical and 5-axis machining centers, touch probes, and robotic automation systems to ensure quality, consistency, and efficiency at every step.
What is CNC Milling?
CNC milling is a subtractive machining process where rotating multi-point cutting tools remove material from a workpiece. A Computer Numerical Control (CNC) Machine controls movements and ensures unmatched repeatability and precision. Unlike manual milling, CNC milling automates all tool paths and speeds, which dramatically reduces human error and production time.
Twin City EDM specializes in 5-axis CNC milling, allowing us to access multiple surfaces of a part without manual repositioning. This process improves surface finishes, maintains consistent tolerance across all features, and opens the door to intricate shapes that would otherwise require secondary operations. This is all about doing multiple complex views in 1 setup to meet tight tolerances and fine-finish requirements.
