Why Choose XFabro for CNC Machining

From instant quoting and DFM review to engineering oversight, material selection, and tolerance control, our workflow supports prototypes, functional parts, and production runs.

  1. Automated 2D/3D Drawing Analysis

    STEP, IGES, STL, DWG, and DXF files are analyzed for size, holes, threads, cavities, surfaces, and other features used for process selection, DFM, and pricing.

  2. DFM Manufacturability Review

    DFM review checks wall thickness, hole depth, tool access, clamping, machining direction, and tolerances, then recommends changes to reduce risk.

  3. Multi-Process Quoting

    Geometry, material, tolerances, and quantity are matched to suitable CNC processes, with comparable pricing and lead-time ranges.

  4. Engineering Review and Quality Control

    Engineers verify the process plan, while in-process quality controls check dimensions, strength, and surface requirements.

  5. Engineering Materials and Tolerance Control

    Choose from common metals and engineering plastics, with process-specific tolerance and surface-finish guidance for fit, function, and service life.
