Prismatic Machining (Milling)

XLI offers both conventional and Computer Numerically Controlled (CNC) machining capabilities for precision manufacturing of prismatic components.

CNC and Conventional


XLI offers both conventional and Computer Numerically Controlled (CNC) machining capabilities for precision manufacturing of prismatic components. In prismatic machining, part surfaces are presented to tools in sequence until all operations are complete. By combining our CNC equipment with specialized rotary fixtures the number of set-ups can be reduced while improving the accuracy and repeatability of part feature locations.

CNC Machining


XLI’s CNC prismatic machining capabilities are provided through high speed vertical or horizontal CNC machining centers with up to four axes of simultaneous control for:

  • Milling
  • Drilling
  • Tapping
  • Boring
  • 3D Contouring

CNC programs can often be created directly from your CAD drawing files. We also have complete capability for CNC programming and direct downloading of programs to our machining centers.

Conventional Machining


XLI’s conventional machining capabilities are provided through manual or semiautomatic mills, lathes, grinders, saws, keyseaters, and finishing equipment for boring, cutting, drilling, broaching, grinding, milling, tapping, and turning.

Our combination of CNC and conventional machining provides flexibility in meeting your overall requirements for completely finished components in prototype to production quantities.
