GFRP Plate Milling  Machined Surface Comparison

More uniformed surface when using HIT Ultrasonic Machining Module.

Highlights of HIT Ultrasonic Machining Module:
  • Reach clients' quality demands
  • Efficiency+50%
  • Reduce Tool Wear 

  • Through subtle ultrasonic vibrations passed from tools to materials, it can effectively eliminate excessive force placing on the materials, resulting in less damage, less waste, and better finish.
  • HIT ultrasonic machining module develops Non-contact power transmission. Without the limitation in rotation speed, the efficiency and  quality will enhance to next level.
  • HIT ultrasonic machining module can reduce cutting heat by dense vibrations. Further, its Non-contact power transmission eliminates the resistance through consumables, lowering thermal impact more effectively.

Advantages in GFRP Plate milling
  • Reduce cutting resistance and  not to destroy the fiber
  • Lower cutting heat
  • Improved quality by reducing chipped width generated 
  • Uniformed cutting surface  enhances surface quality
  • Low cost to produce
  • Less tears generated
  • reach clients’ expectations
  • Easily to generate laceration, more chipped width.
  • Efficiency + 50%
  • Lower tool wear
  • Short tool life
  • Higher probability need to repair broken structure


GFRP has been normally applied in automobile, aerospace, infrastructure construction since 20 century and shape in different spec in response to various demands, such as GFRP honeycomb machining. 

In this case we will work with GFRP plate milling which is more common in GFRP application. Under the condition in using clients chose tools, HIT ultrasonic machining module had greater roughness and increased the efficiency 50%.
  • the cutting heat generated by the glass fiber honeycomb processing is prone to change its mechanical properties.
  • Insufficient work piece quality and different weaving methods in raw materials influence the cutting force adjustment.
  • Difficult maintenance and high cost of repairing damaged materials are another pain points to manufacturers.
