PCD Corner Radius End Mill

PCD Corner Radius End Mills: The Ideal Choice for Efficiency, Precision, and Superior Wear Resistance

Our PCD Corner Radius End Mills (also known as PCD Bull Nose End Mills) are high-performance cutting tools engineered to meet the challenges of precision machining non-ferrous metals and highly abrasive non-metallic materials in modern manufacturing. The cutting edges feature meticulously brazed or sintered Polycrystalline Diamond (PCD) tips on a robust solid carbide body, ensuring exceptional machining performance and an extended operational lifespan.

Core Features & User Benefits:

• Exceptional Wear Resistance & Tool Life:
  PCD material possesses extreme hardness, offering wear resistance far superior to traditional carbide tools and coated tools. This translates to significantly longer tool life, reducing downtime caused by tool changes and wear, thereby lowering overall production costs.
• Excellent Machined Surface Quality:
  PCD cutting edges achieve a very low coefficient of friction and maintain sharpness. Combined with the corner radius (R-corner) design, this effectively minimizes cutting vibrations and edge chipping, resulting in mirror-like surface finishes, especially suitable for parts with stringent surface quality requirements.
• High-Speed & High-Efficiency Machining Capability:
  The excellent thermal stability and conductivity of PCD allow these tools to withstand higher cutting speeds and feed rates. This not only dramatically increases machining efficiency and shortens production cycles but also maintains stable performance under high-speed cutting conditions.
• Reinforced Cutting Edge Design:
  Compared to the sharp corners of standard flat-end mills, the corner radius design effectively distributes cutting forces, enhancing the strength and toughness of the cutting edge. This makes it less prone to chipping and is particularly well-suited for profile milling and bottom clearing of cavities.
• Wide Material Adaptability:
  Especially effective for machining various non-ferrous metals (e.g., aluminum alloys, high-silicon aluminum, copper alloys, magnesium alloys), composite materials (e.g., Carbon Fiber Reinforced Plastics – CFRP, Glass Fiber Reinforced Plastics – GFRP), graphite, engineering plastics, acrylics, wood, and green/sintered ceramics.

Main Application Areas:

• Automotive Industry: Precision milling of aluminum engine blocks, gearbox housings, wheel hubs, and other components.
• Aerospace: Profile machining and surface finishing of aircraft structural parts and composite material components.
• Electronics (3C) Industry: High-gloss machining of aluminum components like mobile phone frames and casings.
• Mold & Die Manufacturing: High-speed, high-precision machining of graphite electrodes and finishing of non-ferrous metal molds.
• Woodworking & Furniture: Precision shaping of high-density fiberboard, solid wood, and composite panels.

Common Specification Examples:

We offer a wide range of standard PCD Corner Radius End Mills, and our strong customization capabilities can meet your specific requirements:

• Diameter (D): Available in a broad selection from micro-diameters to large diameters, e.g., commonly from 3mm to 25mm; larger or smaller diameters can be customized.
• Corner Radius (R): A variety of corner radius options are available, such as R0.2mm, R0.5mm, R0.8mm, R1.0mm, R1.5mm, R2.0mm, etc. Special R-corners can also be custom-made.
• Length of Cut (LOC): Different effective cutting edge lengths are available to suit various machining depths.
• Overall Length (L): Standard and extended lengths are available to accommodate different machine tools and workpiece requirements.
• Number of Flutes: Typically designed with single, 2, 3, or 4 flutes. More flutes can be customized based on the material being machined and processing requirements (e.g., chip evacuation, surface roughness).
• Shank Type: Standard straight shanks (HA/HB); other shank types can be customized according to customer equipment.
• Cooling Method: Can be designed for external cooling or with internal coolant holes (center or side outlets) to enhance cooling and lubrication, thereby extending tool life.

Please note: The specifications listed above are common examples; we can manufacture to your specific requirements.

Professional Customization Service:

We understand that standard tools may not always meet unique machining scenarios. Therefore, we offer comprehensive customization services for PCD Corner Radius End Mills. You can provide us with your specific workpiece material, processing requirements (e.g., precision, surface finish, efficiency), machine tool conditions, etc., to request customization. Our professional team will work closely with you to design and manufacture the PCD tools best suited for your application.

Customizable parameters include (but are not limited to):

• Tool diameter, corner radius size, length of cut, overall length
• Selection of PCD grade (optimized for different materials)
• Number of flutes, helix angle, rake and clearance angles, and other geometric parameters
• Shank diameter and form (e.g., straight shank, weldon flat, Morse taper shank)
• Internal coolant hole design and configuration
• Special coating requirements (although PCD itself is not typically coated for cutting, the body or shank may require specific treatments)
