CNC milling is a machining technique that creates highly accurate and precise components from a wide range of materials. During the process, a computer program replicates a design file by controlling rotating multi-point cutting tools to remove excess material from a workpiece. The result is a finished custom-designed component that matches the CAD model exactly.

The CNC milling process is compatible with many types of metals and plastics, from hardened steel to soft plastics to wood. Whether you need a prototype or a large production run, Mathy Machine’s large facility and state-of-the-art CNC equipment can meet your needs. No matter how complex your project is, our experienced team can craft your component to comply with your specifications and industry regulations, with part features that include slots, pockets, threads, and chamfers.

We specialize in 4- and 5-axis milling, achieving tight tolerances and highly intricate results. Our advanced CNC milling technology produces precise results quickly and includes equipment such as:
  • DMG Mori NHX4000 Horizontal Machine Center
  • Doosan DNM 5700S Vertical Machining Center
  • Haas VM-2 Vertical Machining Center
  • Mori Seiki MV-40 Vertical Machining Center
