Aerospace & Automotive Glass Fiber (GFRP) Honeycomb Milling

1.Not only meeting the customer inclined surface qualities, but increases the roughing effcicency by 4 times 2.At the same quality standard, the finishing effcicency can be increased by 2 times

the cutting heat generated by the glass fiber honeycomb processing is prone to change its mechanical properties.

The tough hollow structure is a major difficulty to machine and tool. Wrong cutting force generated by conventional
CNC machining may causes severe burrs and tears in the fiber layer. 

Difficult maintenance and high cost of repairing damaged materials are another pain points to manufacturers.

HIT Ultrasonic Machining Module Efficiency Test in GFRP Honeycomb machining:

Following charts below show disparities between using HIT Ultrasonic machining and Non-ultrasonic machining.
We increased GFRP rough milling efficiency to 300% and fine milling efficiency to 100%!

The fiberglass honeycomb structure has the advantage of saving material, light weight, high hardness and high rigidity. Unlike Nomex can only bear high pressure in the longitudinal direction, it can withstand multi-faceted forces.

The application of GFRP currently used in the aerospace industry for wings, nacelles, and spoilers. Also, it is normally used in architecture and lightweight automobile.

In this case, we will see how HIT ultrasonic machining module assist in GFRP honeycomb machining. We overcome GFRP extremely toughness and structure problem, effectively enhancing machining efficiency to 2-3 times within the accepted quality.
