What is Titanium CNC Machining?
Titanium is a lightweight, high-strength metal renowned for its exceptional corrosion resistance, biocompatibility, and strength-to-weight ratio.
High-performance CNC machining of titanium alloys (Grade 2, Grade 5/Ti-6Al-4V, and more) for making it ideal for aerospace, medical, and industrial applications.
Our advanced CNC mills and lathes deliver complex, lightweight titanium components with unmatched precision.
Why Choose Titanium CNC Machining?
Lightweight
45% lighter than steel with comparable strength.
Corrosion Resistant
Naturally forms a protective oxide layer, even in saltwater.
Biocompatible
Non-toxic and osseointegration-friendly (ideal for medical implants).
High-Temperature Performance
Retains strength up to 600°C (1112°F).
Types of Titanium Alloy

Composition
Description
Application
Grade 1
99.5% Ti
The softest, most ductile, and most formable of all the grades
Plating, piping, tubing, automotive, power generation, aerospace
Grade 2
99% Ti
Plating, piping, tubing, automotive, power generation, aerospace
Plating, piping, tubing, automotive, power generation, aerospace
Grade 3
99.2–99.7% Ti
Least commonly used pure titanium grade, stronger than Grades 1 and 2 but less ductile and formable
Heat exchangers, piping, marine, and chemical processing
Grade 4
98.9–99.5% Ti
Strongest of all Alpha titanium alloys (comparable to stainless and low-carbon steel)
tanks, reactors, valves, pipes, connecting rods, pumps), surgical implants, aerospace, chemical processing
Grade 5
88-90% Ti
high strength, good ductility, heat resistant, can be heat treated, formabile, corrosion resistant
Engine parts, crankshafts, valve seats, connecting rods, exhausts, suspension, frames
Grade 6
92% Ti
Strength, ductility, creep resistance, temperature stability, suitable for higher service temperatures of 900°F
Casings/rings in turbine engines, structural members/frames in aerospac
Grade 7
99% Ti
Highest corrosion resistance of all titanium alloys, can withstand harsh environments, nearly identical to Grade 2
Welding, forming, desalination, chemical manufacturing
Grade 11
99.75% Ti
Corrosion resistance (particularly in acidic environments), similar to Grades 1 and 2, crevice corrosion resistance, highly ductile, impact toughness
Welding, chemical processing and storage, ducts, pumps, and heat exchangers
Titanium CNC Machining Parameter
Parameter
Roughing
Finishing
Notes
Spindle Speed
500–1,200 RPM
800–2,000 RPM
Lower for large tools, higher for small diameters.
Spindle Power
≥ 10 kW (for stable cuts)
≥ 5 kW (lighter cuts)
High power avoids stalling.
Feed Rate
200–600 mm/min
100–300 mm/min
Adjust based on chip load.
Cutting Depth
1–5 mm
0.1–1 mm
Aggressive roughing requires rigid setup.
Cutting Width
30–70% of tool diameter
10–30% of tool diameter
Avoid full-width slotting.
Machining Accuracy
±0.05 – 0.1 mm
±0.01 – 0.02 mm
Tight tolerances need slow feeds.
Surface Roughness
3.2–6.3 µm
0.8–1.6 µm
Finishing passes improve Ra.
Tool Type
Carbide (AlTiN-coated)
Carbide (sharp, polished)
Avoid HSS; coatings reduce heat.
Tool Diameter
6–20 mm (end mills)
3–10 mm (ball nose/fine)
Larger tools for roughing.
Coolant Type
High-pressure emulsion
Mist or flood coolant
Never dry machine!
Chip Load
0.08–0.15 mm/tooth
0.03–0.08 mm/tooth
Softer grades tolerate higher loads.
Ramp Angle
3–10° (helical entry)
≤5° (for precision)
Reduces tool impact.
Stepover
40–70% (radial engagement)
10–30% (light passes)
Lower stepover = better finish.
