HIT Achievements in Titanium Drilling

HIT’s ultrasonic-assisted machining technology provides the superimposition of the tool rotation with a high-frequency oscillation in longitudinal direction, generating over 20,000 times of micro-vibration per second. The mechanism helps reduce cutting forces and facilitates chip removal process.

The reduction in cutting forces not only decreases frictions between tools and workpieces, but also allows feed rates to be increased. This mechanism along with the high pressure (70bar) coolant through spindle (CTS) feature help lower the heat produced during the machining process. This greatly improves the quality of workpieces and the stability of tool life, and saves a huge amount of processing time.

Facilitating chip removal process diminishes frictions on both tools and workpieces caused by excessive amount of chips. HIT’s ultrasonic high-frequency micro-vibration allows chips to break easily and lessens the occurrences of entangled chips. This also displays a great benefit to both the quality of workpieces and the stability of tool life.

Drilling titanium alloys with ultrasonic-assisted machining technology, the reduction in cutting forces and improvement in chip removal process allow better control of the quality of workpieces and the stability in tool life.
