The popular material "Carbon Fiber Reinforced Composite (CFRP)" has the characteristics of high strength, light weight, and high rigidity. It is resistant to acid and alkali and abrasion, so it has a wide range of applications and is suitable for manufacturing various objects. Because of such characteristics, CFRP has been used more and more in the aerospace field in recent years. For example, composite materials are often used in the fuselage, tail and ailerons of aircraft to improve the structural strength of the vehicle and reduce the weight of the vehicle.

However, because such materials such as carbon fiber are harder than aluminum alloys, they are not easy to process, and the efficiency has been difficult to improve. The cutting heat generated by the honeycomb processing of glass fibers easily changes its mechanical properties. The rigid hollow structure is the main difficulty of processing machine tools. Incorrect cutting forces from traditional CNC machining can cause severe burr delamination and tearing in the fiber layer.
 

Ultrasonic Machining has created a new processing method in aerospace composites:

Ultrasonic machining technology has created a new processing solution for the aerospace industry, which efficiently processes high-performance materials. The advantage of ultrasonic technology is that high-frequency motion brings less harm to processing. Ultrasonic technology can achieve better results with fewer consumables. It is very suitable for processing aerospace composites.
Hantop Intelligence Tech. provides a wealth of processing solutions. Through the subtle ultrasonic vibration from the tool to the material, it can effectively eliminate the excessive force exerted on the material, thereby reducing damage, reducing waste and obtaining a better finish. In addition, the HANTOP ultrasonic processing module can reduce cutting heat through dense vibration, and its non-contact power transmission eliminates the resistance of consumables and reduces thermal effects more effectively.
 

HIT Ultrasonic Machining Module Highlight in aerospace composites machining: 

Recently, HIT Ultrasonic machining module has been proven effective in CFRP plate drilling no matter in quality or tool life. And for other composites materials, HANTOP has actual GFRP machining cases that can increase processing efficiency by 300%, and Nomex honeycomb machining cases which greatly enhanced quality.
