  • HIT Achievements
  • Industry Application
  • Back to list
Picture of Artifact:
In this case, our customers have problems in enhancing tool life and efficiency under the quality standard. 1 tool is only available for 20 holes, and the cycle time/ per hole is 4 min 30 seconds.

 

Machining Parameters：
With HIT ultrasonic machining module, we have supported our customer optimizing parameters with the same rotary speed and tool, improving tool life (20 to 30 holes) & efficiency.( 4 min 30 sec to 2 min 27 sec)
Tool Holder Type HSKE40
Method Non-Ultrasonic HIT
Spindle speed(rpm) 8500 8500
Feed rate(mm/min) 100 250
Depth(mm) 8 8
Tool life 20 20(Still available)
Cycle time(Hole) 4 min 30 sec 2 min 27 sec

Tool Comparison between before and after machining:
Tool wear is unrecognizable after tapping. It’s estimated can tap at least 10 holes.


Comparison of Processing Time
Cycle Time from 4 min 30 sec reduced to 2 min and 27 second.


Highlights of HIT Ultrasonic Machining Module
In case of using client chosen tool,
  • Reaching clients-accepted quality
  • Efficiency+ 46%
  • Tool life+ 50%, and it is still available at least 10 holes.
