Bronze Bonded Diamond Ultra-Thin Cutting Blade, 0.3mm Thickness (Down to 0.2mm)

Product Description

Product Name:

Bronze Bonded Ultra-Thin Diamond / CBN Cutting Blades (Sintered / Metal Bond)

Key Specifications:

Product Description:

These bronze-bonded ultra-thin cutting blades are precision-engineered for high-accuracy dicing, slicing, and slotting of hard and difficult-to-cut materials.

Available in two abrasive types – Diamond and CBN – these blades combine the durability of sintered bronze bonding with ultra-thin kerf geometry to minimize material waste while maintaining cutting stability.

Part 1: Bronze Bonded Diamond Ultra-Thin Blade

For Hard & Brittle Materials

Key Features:

✅ Bronze Bond (Sintered) – Stronger than resin or electroplated bonds; provides excellent grain retention and longer blade life
✅ Ultra-Thin Profile (0.2-0.3mm) – Minimizes kerf loss (narrow cut width), maximizes material yield
✅ Diamond Abrasive – Cuts the hardest materials including ceramics, glass, and tungsten carbide
✅ Customizable Dimensions – Outer diameter, inner hole, thickness, and grit size available per customer requirements
✅ Precision Cutting – Ideal for dicing wafers, slicing rods, slotting precision components

Typical Applications:

• Dicing ceramic substrates and alumina wafers

• Cutting glass and quartz rods/tubes

• Slicing ferrite cores for electronics

• Cutting tungsten carbide and hard metals

• Semiconductor material dicing

• Optical glass precision cutting

Part 2: Bronze Bonded CBN Ultra-Thin Blade

For Ferrous Metals & Hardened Steels

Key Features:

✅ CBN Abrasive – Chemically stable with ferrous materials; does not react with iron at high temperatures (unlike diamond)
✅ Bronze Bond – Strong grain retention, long blade life, maintains shape under heavy use
✅ Ultra-Thin Kerf – Reduces material waste when cutting expensive hardened steel components
✅ Customizable – Any dimension, thickness, or grit size available
✅ Precision Slitting – Ideal for cutting hardened steel rods, tubes, and precision components

Why CBN Instead of Diamond for Steel?

Typical Applications:

• Cutting hardened steel rods and bars (HRC 45-65)

• Slitting bearing steel components

• Dicing tool steel blanks

• Cutting cast iron parts

• Precision slotting in ferrous alloys

• Cutting high-speed steel (HSS)

Part 3: Bronze Bond Technology – Why Choose Sintered Metal Bond?

Compared to other bonding methods, bronze (sintered metal) bond offers unique advantages for ultra-thin cutting blades.

Advantages of bronze bond for ultra-thin blades:

✅ High grain retention – Diamond/CBN grains are firmly held in the bronze matrix; grains do not pull out easily
✅ Long blade life – Suitable for production environments with high cutting volumes
✅ Maintains thickness – Bronze bond resists wear, keeping the kerf consistent throughout blade life
✅ Cooler cutting – Metal bond dissipates heat better than resin
✅ Can be re-dressed – When loaded, the blade can be dressed to expose fresh abrasive (unlike electroplated which cannot be dressed)
