Comprehensive Analysis of Custom Titanium Alloy CNC Machining Technology

Mechanical Properties

• Excellent strength-to-weight ratio (tensile strength: 400-1400MPa, density: only 4.51g/cm³)
• Balanced ductility and toughness (elongation ≥10%)
• Outstanding high-temperature stability (retains 80% of room-temperature strength at 300-500℃)

Chemical and Physical Properties

• Exceptional corrosion resistance (forms a dense oxide film in seawater, acid-alkaline environments)
• Superior biocompatibility (non-toxic, non-sensitizing)
• Non-magnetic and low conductivity (magnetic permeability close to vacuum, electrical conductivity 3.1% of copper)

Processing Value

• Long service life (3-5 times that of traditional metals)
• Full-scenario adaptability (stable operation from -253℃ to 600℃)
• High-end empowerment (enhances product technical content and added value)

Processing Challenges

Breakthrough Solutions

Cutting Parameters

Adopt "low rotational speed, high feed rate, small cutting depth" – spindle speed: 500-3000r/min, feed per tooth: 0.03-0.15mm.

Cooling and Lubrication

Equip high-pressure cooling systems (pressure ≥30MPa) with water-soluble cutting fluids (concentration: 10%-15%).

Vibration Suppression

Use high-rigidity machine tools, short-edge cutters and rigid tool holders, and multi-point positioning for part clamping.

Stress Control

Incorporate low-temperature aging during processing (200-300℃, heat preservation for 2-4 hours) and adopt the "roughing – semi-finishing – stress relief – finishing" processing flow.

Tool Materials

• Preferred: Ultra-fine grain cemented carbide with TiAlN or AlCrN coatings
• For difficult-to-machine alloys: Diamond-coated tools

Geometric Parameters

End Mills

• Multi-flute design (4-10 flutes)
• Rake angle: 5°-15°
• Cutting edge radius: 0.02-0.05mm
• Helix angle: 30°-45°

Turning Tools

• Positive rake angle inserts (+5°~+10°)
• Nose radius: 0.2-0.5mm
• Wide-groove chip breakers

Usage and Maintenance

• Establish wear monitoring systems (replace when flank wear reaches 0.2-0.3mm)
• Adopt climb milling
• Store tools in a dry environment
