Advantage of HALNN Tools:

1. Long life, reducing customer processing cost

2. There is no burr in the orifice, which improves the surface quality of the workpiece.

3. PCD center drill for smoother chip removal

4. PCD drill integrated roughing and finishing, and is used in drilling and milling to save processing time and improve processing efficiency

5. Products can be customized according to customer needs

Design factors of Halnn tools for composite materials  :

1. Minimize tool wearing

2. Eliminating the phenomenon of burrs on the surface of the workpiece

3. The breakthrough of various technological problems in drilling, milling and reaming

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.

(1)

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 improving the durability.

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

(2)

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 countersinking composite tool has more excellent effects and advantages in 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.

(3)

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 imported one.

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

(4)

Carbon Fiber Composites - Diamond Coated Milling Cutter

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 more 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.

(5)

Honeycomb material - Carbide crushing milling cutter

Processing material: Aramid paper honeycomb

Advantages: 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.
