Premium Diamond Blade Alloy Milling Cutter for Precision Cutting

1. Key Characteristics & Design

• Cutting Material: Features a PCD tip brazed onto a tungsten carbide substrate. PCD consists of synthetic diamond particles sintered together under high pressure and temperature, offering extreme hardness and wear resistance.

• Geometry: The MGMN ISO designation indicates a negative-style, square-shaped insert with a very high cutting edge count (typically 8 edges). This geometry provides excellent strength and economy.

• Cutting Edge: Can be supplied with a sharp edge for free-cutting or a honed edge (T-land/K-land) for increased strength and chip resistance.

2. Performance Advantages

• Exceptional Wear Resistance: Significantly outperforms carbide and ceramic tools when machining abrasive materials, leading to a dramatic increase in tool life—often by 50 to 100 times.

• High-Speed Capability: Enables very high cutting speeds (Vc), drastically reducing machining cycle times and improving productivity.

• Superior Surface Finish: Produces excellent and consistent surface quality, often eliminating the need for secondary finishing operations.

• Low Cutting Forces: The sharp, polished edge of PCD generates lower cutting forces, reducing the risk of part deformation, especially in thin-walled components.

3. Primary Applications

These inserts are ideally suited for machining:

• High-Silicon Aluminum Alloys (e.g., AlSi12, AlSi17Cu4)

• Copper and Copper Alloys

• Sintered Tungsten Carbide (pre-sintered state)

• Fiber-Reinforced Plastics (FRP) like CFRP and GFRP

• Graphite, Wood Composites, and other highly abrasive non-metals.

4. Machining Operations

MGMN PCD inserts are primarily used in:

• Face Milling

• Shoulder Milling

• Contour Milling
