Gradient Tungsten Carbide Rod for High Precision Micro Tools Manufacturing

Advanced Carbide Material Solution for Ultra Precision Machining

With the rapid development of precision manufacturing technology, industries such as electronics, medical equipment, aerospace, and semiconductor production require increasingly smaller and more accurate components.

Manufacturing these precision parts requires advanced micro cutting tools with:

• Extremely high dimensional accuracy

• Excellent edge stability

• Long service life

• Reliable machining performance

The carbide rod is the fundamental material used for producing micro tools.

The performance of the carbide blank directly determines:

• Cutting accuracy

• Tool rigidity

• Edge durability

• Machining efficiency

Traditional carbide rods often face limitations when used for micro machining applications.

Small diameter tools require a special balance between:

High hardness:

For maintaining sharp cutting edges.

High toughness:

For preventing micro fracture and tool failure.

Traditional carbide materials usually provide uniform properties throughout the entire rod.

However, micro tools have different stress requirements in different areas.

The cutting edge requires:

• Maximum hardness

• Excellent wear resistance

• Stable edge retention

The tool body requires:

• High strength

• Better rigidity

• Improved fracture resistance

To meet these demanding requirements, JINXIN developed:
