Use Case
This structure is used for CNC High-Speed Machining (HSM) strategies, non-ferrous metallurgy training, composite routing, and "Mirror Finish" surface generation processes.
Non-Ferrous Machining Limits
PCD tools CANNOT be used on steel or iron (at high temperatures, the carbon reacts and melts the diamond). However, they are unrivaled for aluminum, brass, and carbon fiber.
Brazing Rigidity
Explains the vibration-free "zero backlash" structure provided by securing the cutting diamond plates to the body with silver or copper alloy brazing rather than screws.
Mirror Finish Quality
Highlights how the incredible sharpness and low coefficient of friction of diamond turn machined aluminum surfaces into mirrors without the need for polishing.
PCD (Polycrystalline Diamond) Milling Cutter - Detailed Specifications
Below is the comprehensive engineering breakdown of each component within the assembly. This data includes standard material selections, ISO tolerances, surface finishes, and critical engineering notes required for manufacturing and assembly.
Integral Cutter Body and Holder
Tool Holder & Body
The rigid mass that houses the tapered shank connecting to the CNC spindle and the main milling section holding the cutting edges in a single piece.
Because it is designed to operate at phenomenal speeds like 30,000 RPM, the dynamic balance of this body must be Flawless (G2.5 class). If the body were two pieces (holder + head), the connection point would deflect under centrifugal force at high speeds, causing vibration. This monolithic design eliminates that deflection.
PCD Cutting Inserts (Polycrystalline Diamond)
Advanced Cutting Material
The black plates containing the hardest cutting material on earth, brazed to the milling body at high temperatures.
PCD is synthesized in a lab environment using High-Pressure High-Temperature (HPHT) processes to bind diamond particles. Its wear resistance is 50 to 100 times greater than carbide tools. Its sharpness is so extreme that it shears through aluminum like butter, preventing heat buildup and leaving a flawless "mirror finish".
