CNC Precision Machining
Advanced precision machining solutions using multi-axis milling and turning to deliver tight tolerances, complex geometries, and repeatable production quality.
PMI offers comprehensive CNC precision machining services supported by a global footprint of advanced equipment and experienced manufacturing teams. With more than 200 high-performance machining centers—including 3, 4, and 5-axis milling and multi-spindle lathes—PMI routinely delivers parts with stringent geometric tolerances and high repeatability.
Common Applications
- Aerospace structural and mechanical components requiring tight geometric control and high reliability.
- Medical device parts with precise dimensional requirements across materials like stainless steel and titanium.
- Semiconductor equipment hardware requiring complex 3D features and tight tolerances.
- Industrial and commercial machine components where accuracy and repeatability are essential.
- Exotic material machining for applications where performance under stress or in extreme environments is required.
Technical Range
PMI’s CNC precision machining capability includes a broad set of machining methods and equipment optimized for complex, high-accuracy components across diverse material classes:
- Multi-Axis Milling: 3, 4, and 5-axis high-speed milling that can machine five surfaces in a single setup, improving geometric control and reducing cycle times.
- High Performance Turning: Precision turning operations for cylindrical and rotational features incorporated with milling or standalone as required.
- Simultaneous 4th & 5th Axis Machining: Enables highly sophisticated part geometries and tighter tolerances in fewer setups.
- Multi-Spindle & Specialized Lathes: Flexible platforms capable of efficient production for a wide variety of component layouts.
- Material Versatility: Experience with standard and exotic alloys including titanium, Inconel, Invar, stainless steels, aluminum, cobalt chrome, and engineered composites such as metal matrix composites, plus machinable plastics like PEEK and UHMWPE.
- Tight Tolerance Production: Routine capability to hold tolerances as close as ±0.0001” in production environments.
