- CNC Milling
  
  CNC milling is one of the most widely used processes in aerospace CNC machining. It involves rotating cutting tools to remove material from a stationary workpiece. Commonly used for airplane structural components, housings, brackets.
  
  Equipment: Modern machining centers (e.g., HAAS VF Series, DMG MORI CMX Series) with high-rigidity structures, high-power spindles (≤20,000 RPM), and precision ball screws/linear guides.
  Performance & Precision: ±0.01mm (±0.0004) accuracy, superior thermal stability, and excellent surface finishes.
- CNC Turning
  
  CNC turning is used to machine cylindrical or rotational aerospace components. In this process, the workpiece rotates while a stationary cutting tool removes material. Comonly used for Airplane shafts, bushings, connectors.
  
  Equipment: Integrated high-precision rotary tables (A/B-axis, ≤±0.005° repeatability) with HEIDENHAIN/FANUC encoders.
  
  Performance & Precision: ±0.015mm (±0.0006) multi-surface accuracy, reduced setups.
- 5-Axis Machining
  
  5-axis machining helps to produce complex aircraft components. This aerospace machining process allows for parts to be manipulated along the X, Y, Z, and linear axes.
  
  Equipment: Simultaneous 5-axis centers (trunnion/dual-table) with SIEMENS/FANUC controls (≤20,000 RPM spindles, 0.0001° rotary resolution).
  
  Performance & Precision: ±0.008mm (±0.0003) positioning accuracy for complex contours, molds, and aerospace parts.
- CNC Drilling
  
  CNC Drilling processes create precise holes for fasteners, fluid passages, and assemblies. Aerospace machining often involves thousands of holes per aircraft, all requiring consistent positioning and diameter accuracy. CNC Drilling is commonly used for Aircraft panels, manifolds, structural parts.
  
  Equipment: Integrated high-precision rotary tables (A/B-axis, ≤±0.005° repeatability) with HEIDENHAIN/FANUC encoders.
  Performance & Precision: ±0.01mm (±0.0004’’) accuracy, superior thermal stability, and excellent surface finishes.

Key Materials Used for Aerospace CNC Machining

To get the definite safety and best performance, materials used to make CNC aerospace parts often require a great strength-to-weight ratio and some other specific characteristics. These metal alloys and materials are top choices for aircraft applications.

Material Types	Common Alloys / Grades	Key Properties	Typical Applications	Machining Considerations
Aluminum Alloys	2024, 6061, 7075, 7050	Excellent strength-to-weight ratio, good corrosion resistance, fatigue resistant, good machinability	Wing spars, fuselage frames, internal parts, seats, handles, structural components	High cutting speed up to 1000 m/min, cooling needed to prevent chip welding, control thin-wall deflection
Titanium Alloys	Ti-6Al-4V, Ti-5Al-5Mo-5V-3Cr	High strength to weight ratio, excellent corrosion resistance, high temperature stability	Airframes, engine parts, landing gear, fasteners	Low thermal conductivity causes heat concentration, low cutting speeds of 30-60 m/min, rigid machine setups are needed
Nickel-Based Superalloys	Inconel 718, Waspaloy	High temperature resistance, excellent creep oxidation corrosion resistance	Jet engines, turbine blades, high-temperature aerospace parts	Very low cutting speeds 10-30 m/min, high tool wear, work hardening, specialized coated tools required
Specialty Alloys	Carbon fiber, fiberglass, aramid fibers	Lightweight, high mechanical strength, thermal stability, chemical inertness	Aircraft fuselage, wings, tooling, moulds	Can be reinforced with glass or carbon fibers, suitable for fine tolerances and high-temperature internal parts
