SNSTC 2025-04-15
The PCD (Polycrystalline Diamond) multi-tooth milling cutter is a high-precision, highly wear-resistant tool designed for high-speed machining. It is widely used in aerospace, automotive manufacturing, electronics, mold processing, and other industries. This tool is particularly suitable for the efficient machining of aluminum alloys, carbon fiber reinforced plastics (CFRP), copper, stainless steel, and other non-ferrous and non-metallic materials.
1.Structure Design of PCD Multi-Tooth Milling Cutter
PCD Material: PCD is composed of diamond micro-particles sintered under high temperature and high pressure, offering exceptional hardness and wear resistance.
Multi-Tooth Design: (Typically 6-30 teeth) This design increases the feed rate while reducing the cutting load on each tooth, enhancing cutting efficiency, machining precision, and surface finish, as well as extending tool life.
Tool Interface: Common interfaces include BT, HSK, ISO, and CAT,etc., which can be selected based on the machine
Tool Body Material: The body is generally made of carbide (tungsten carbide) or mold steel, with PCD tip welded or embedded at the cutting edges.
Application: Suitable for precision milling, drilling, chamfering, and boring, ect., widely used in aerospace, automotive manufacturing, electronics, and mold production.
2. Applicable Machining Materials
The PCD multi-tooth milling cutter is suitable for machining difficult-to-process non-ferrous and non-metallic materials, such as:
Aluminum Alloys (e.g., engine cylinder heads, transmission housings, aerospace structural parts)
Carbon Fiber Reinforced Plastics (CFRP) (e.g., aircraft parts, wind turbine blades)
Copper & Brass (e.g., electronic components, precision connectors)
Plastic and Resin Materials (e.g., 3C products, medical devices)
Ceramic Matrix Composites (CMC) (e.g., aerospace , heat-resistant parts)
