Standard CNC Machining Aluminum Capabilities

  • Tolerance: Standard machining tolerance of ±0.005 inches (±0.127 mm). Tighter tolerances down to ±0.001 inches (±0.0254 mm) are available upon request.
  • Maximum Part Size: Up to 60" x 30" x 25" (1524 mm x 762 mm x 635 mm).
  • Surface Finish: Standard finishes range from 125 µin (as-machined) to 8 µin or better with secondary polishing operations. Anodizing, powder coating, and chemical film conversion coatings are available.
  • Lead Time: Prototype parts typically delivered within 1-2 weeks. Production volumes are quoted based on project complexity and quantity.
  • File Formats Accepted: STEP, IGES, X_T, SLDPRT, CATPART, 3DM, DWG, DXF.

Common Aluminum Alloys for CNC Machining

Alloy Common Temper Key Characteristics Typical Applications
6061 T6 Excellent strength, good weldability, and high corrosion resistance. The most versatile general-purpose alloy. Frames, brackets, automotive parts, marine fittings.
7075 T6 Very high strength, comparable to many steels. Excellent fatigue strength but lower corrosion resistance than 6061. Aerospace structures, high-stress mechanical components, mold tools.
2024 T3, T351 High strength-to-weight ratio, good fatigue resistance. Primarily used in aircraft structures. Aircraft fuselage skins, wing structures, truck wheels.
5052 H32 Excellent corrosion resistance, especially in marine atmospheres. Good formability and weldability. Marine components, electronic chassis, fan blades, pressure vessels.
MIC-6 Cast Plate Stress-relieved cast aluminum plate. Exceptional stability and flatness with minimal internal stress. Jigs, fixtures, base plates, mounting plates for optical equipment.

  • The definition of the CNC

    With CNC, each object to be manufactured gets a custom computer program, usually written in an international standard language called G-code, stored in and executed by the machine control unit (MCU), a microcomputer attached to the machine. The program contains the instructions and parameters the machine tool will follow, such as the feed rate of materials and the positioning and speed of the tool's components. Mills, lathes, routers, grinders and lasers are common machine tools whose operations can be automated with CNC. It can also be used to control non-machine tools, such as welding, electronic assembly and filament-winding machines.
