HIT's Goal in Machining D2/X165CrMoV12 Tool Steel
The goal is to enhance the machining efficiency and improve the stability in tool life, while maintaining great surface quality.
Ultrasonic-Assisted Machining D2/X165CrMoV12 Tool Steel Results
D2/X165CrMoV12 Tool Steel Bottom Milling : Machining Efficiency
With HIT Ultrasonic, the cutting speed can be raised 2 times faster than that without ultrasonic, resulting in the increase in feed rate. Consequently, it only took half of the original processing time to complete the bottom milling of D2/X165CrMoV12 tool steel.
D2/X165CrMoV12 Tool Steel Bottom Milling : Workpiece Quality
(Figure 4. comparison of bottom milling D2/X165CrMoV12 tool steel workpiece surface quality between HIT ultrasonic and non ultrasonic)
Throughout the machining trials, HIT discovered that there was no direct influence of ultrasonic-assisted machining technology on the workpiece surface quality.
The key to better surface quality lies in the reduction of the size of processing path pitch. When the size of processing path pitch was reduced, it indicated that the tool needed to run more processing paths to finish the entire process, which took even more processing time.
This is where HIT ultrasonic-assisted machining technology came for help! The biggest benefit of HIT ultrasonic is to enhance the machining efficiency, so that even when the size of processing path pitch was reduced, the processing time would not have to take too long.

(Figure 5. comparison of the tool wear between HIT ultrasonic and non ultrasonic bottom milling on D2/X165CrMoV12 tool steel)
With the high-frequency micro-vibration of HIT ultrasonic, the reduction in cutting force helped reduce the tool wear when machining this kind of hard metal steel material.
