The rapid development of the aerospace industry is inseparable from the high-quality and efficient processing of parts and components in the aerospace field. In the processing of parts, materials and the tools used for processing are very critical. The development and progress of cutting tools promote the continuous advancement of the aerospace field. Aircraft such as airplanes or spaceships have high requirements for their manufacturing materials in order to ensure flight safety during flight, and high-performance materials that can withstand high temperatures and high pressure for a long time are required. The particularity of the application occasions of aerospace products determines the special requirements for the materials used in aerospace components, many difficult-to-machine materials such as stainless steel, aluminum alloys, titanium alloys, and high-temperature alloys, carbon fiber composite material, honeycomb material have been widely used in the aerospace industry. 

The gradual application of new materials, new structures, and new technologies in the processing of the aerospace industry has made it more and more difficult to process aerospace parts. As a result, the machining of aerospace parts must use a large number of high-performance standards tools and special tools to meet the increasingly high processing requirements.

Processing methods: Turning, Milling, Drilling, Reaming, boring

Commonly processed workpieces in aerospace are aircraft parts, which are shells, blisks, intermediate shells, landing gear parts, landing gear, pod frames and aileron parts, etc. At present, the tool materials widely used in the aerospace manufacturing industry mainly include the following categories: tool steel (carbon tool steel, alloy tool steel, high-speed steel), cemented carbide, ceramics, PCD, and other superhard tool materials. Halnn PCD tools perform very well in the field of processing carbon fiber composite materials and can provide a series of matching tools and solutions based on the customers' requirements.

Solutions:

1. Honeycomb material - Carbide crushing milling cutter

Processing material: Aramid paper honeycomb

Advantages: In integral design, the helical groove crushing blade can achieve higher cutting speed and feed; various sizes cover various forms of honeycomb core material processing, and the resistance during chip removal and chip separation is smaller.

Diameter of Carbide crushing milling cutter: φ22~φ95 (0.88"~3.75")  Customized special diameter according to client needs.

2. Processing material: carbon fiber composite material, honeycomb material

Processing part: aircraft wing

Tool material: PCD and carbide 

The problem: eliminating burrs on the workpiece, and PCD tools showing greater advantages in high-precision hole processing and difficult-to-machine materials.

3. Carbon fiber composite material - PCD combined tool for drilling, reaming, and countersinking

Two structures: sintered PCD drill-reaming compound tool and inserted PCD- drill-reaming compound tool. The sintered PCD drill-reaming and the countersinking composite tool have more excellent effects and advantages in the processing of laminated materials.

Processing material: T700 composite material

Advantages: Drilling and countersinking are completed at one time, omitting the work of tool retraction, tool changing, and tool indexing, which greatly shortens the processing time; the polishing edge can squeeze the hole wall.

Diameter of PCD Combined tool: φ2 ~ φ16 Customized special diameter according to client needs.

4. Carbon fiber composite material - PCD twist drill

Processing material: T700 composite material

Advantages: The solid PCD drill structure has a sharp edge, which can effectively suppress material delamination and burrs, and greatly improve durability.

Diameter of PCD twist drill: φ2~φ20   Customized special diameter according to client needs.

5. Carbon Fiber Composites - Diamond Coated Milling Cutter

In roughing and finishing for carbon fiber composites (CFRP) and glass fiber composites (GFRP), the left and right helical edges effectively suppress delamination and burrs and are used for plunging and side milling of carbon fiber materials.

Processing material: T700 composite material.

Advantages: The coated diamond makes the tool light and fast; the processing material has no burr, and the smoothness is high; the requirements for the machine are general.

Diameter of Diamond Coated Milling Cutter: φ3~φ12 Customized special diameter according to client needs.

6. Carbon fiber composite material - PCD Countersink drill

90°/100°/120°/130° etc countersinking angles in EN/AS are supplied.

Processing material: T700 composite material.

Advantages: high durability of PCD cutting edge; good retention of surface roughness index; high thread accuracy, quick replacement of drill; wear resistance of base is better than the imported one.

Tools Base diameter: φ2~φ16. Customized other base sizes and drill angle
