PCD End Mill: The Ultimate Cutting Tool for Non-Ferrous and Abrasive Materials
I. Core Technological Advantages of DLC Coating
DLC (Diamond-Like Carbon) coating is a metastable amorphous carbon material prepared under vacuum conditions via Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) processes. It combines the high hardness of diamond with the lubricity of graphite:
Exceptional Hardness and Wear Resistance
Hardness can reach 2000-8000 HV, significantly higher than traditional TiN or TiAlN coatings.
Extremely low coefficient of friction (0.05-0.2), reducing cutting heat and built-up edge (BUE) formation.
Unique Surface Properties
High chemical inertness, effectively suppressing affinity reactions with materials like aluminum and copper.
Smooth surface ensures smooth chip evacuation and prevents built-up edge formation.
II. Optimal Application Scenarios
Preferred Application Materials
Non-Ferrous Metal Machining: Aluminum alloys (especially high-silicon content), copper alloys, brass, babbitt metal.
Composite Materials: Carbon Fiber Reinforced Plastic (CFRP), fiberglass, epoxy-based materials.
Difficult-to-Machine Non-Metals: Graphite electrodes, ceramics, reinforced plastics.
Specific Steel Components: Precision machining of pre-hardened steel (<45 HRC) and stainless steel.
Applications to Avoid
Heavy-duty roughing of ferrous metals (prone to chemical dissolution wear).
Continuous cutting of high-toughness materials (e.g., titanium alloys).
Prolonged machining of high-temperature alloys.
