Titanium, renowned for its exceptional strengthtoweight ratio, excellent corrosion resistance, and hightemperature performance, is a premier choice for aerospace, medical, and highperformance automotive components. However, its poor thermal conductivity and tendency to workharden make it a challenging material for CNC machining. Success hinges on implementing a set of proven best practices to ensure efficiency, precision, and tool longevity.
1. Strategic Tool Selection and Application
The correct cutting tools are paramount. Use sharp, premiumgrade carbide tools with specialized coatings like Titanium Aluminum Nitride (TiAlN) or Aluminum Titanium Nitride (AlTiN) to reduce heat generation and resist wear. Opt for tools with a positive rake angle to minimize cutting forces and a lower number of flutes to provide ample chip clearance, preventing recutting of chips and heat buildup.
2. Mastering Feeds and Speeds
A conservative approach to speed with an aggressive, highfeed rate is the golden rule for titanium. Low surface speeds (SFM) are critical to control cutting temperatures. Conversely, maintaining a high, consistent chip load prevents the tool from rubbing against the workpiece, which causes workhardening and rapid tool failure. Utilizing trochoidal milling paths can further help by distributing tool engagement and heat more evenly.
3. Uncompromising Rigidity and Coolant Management
CNC machining The entire machining system—machine tool, fixture, workpiece, and tool holder—must be extremely rigid to withstand titanium's high cutting forces. Vibration is the enemy of surface finish and tool life. Furthermore, a highpressure, highvolume coolant system is nonnegotiable. It must be directed precisely at the cutting edge to effectively remove heat and flush chips away, preventing thermal damage to both the part and the tool.
