Advantages:
PCD circular saw blades are not easy to fall off during work; they are sharp, have straight edges and high cutting speed.
Application:
PCD diamond circular saw blades are suitable for precision cutting of ceramic tiles, wall tiles, asbestos tiles, gypsum boards and particle boards.
Detailed explanation of the functions and applications of PCD circular saw blades
PCD (polycrystalline diamond) circular saw blades are efficient cutting tools. Their core advantage lies in the use of a blade head made of super-hard diamond particles and metal binders, which is suitable for precision processing of a variety of difficult materials. The following are its detailed functions, features and application scenarios:
1. Core functions
Efficient cutting of hard materials
Wood processing: Especially suitable for high-density boards (such as OSB, MDF) or hardwood (such as teak, mahogany) containing resins and adhesives to avoid rapid wear of ordinary blades.
Metal processing: Specializes in fast cutting of non-ferrous metals (aluminum, copper, aluminum alloy profiles, cast aluminum parts), such as automotive aluminum wheels and aviation parts.
Composite materials: Precise cutting of carbon fiber, glass fiber reinforced plastic (GFRP), etc., to reduce delamination or burrs.
High precision and finish
The cutting surface can be directly used for precision assembly (such as electronic component substrates, optical components), reducing subsequent grinding processes.
2. Core Advantages
Excellent wear resistance
Lifespan is 10-50 times that of carbide saw blades, especially suitable for continuous production lines (such as tens of thousands of cuts per day in aluminum profile factories).
Significant economic efficiency
Long-term use reduces replacement frequency and downtime costs, suitable for large-scale industrial scenarios (such as batch processing in furniture factories).
High speed and high efficiency
Supports high speed (up to 5000 RPM or more), improves processing efficiency, and is suitable for fast material cutting in automobile manufacturing.
3. Typical application scenarios
Construction industry: fast cutting of aluminum curtain walls and broken bridge aluminum door and window profiles.
Automobile manufacturing: precision machining of aluminum alloy parts for battery trays and motor housings.
Electronics industry: dust-free cutting of ceramic substrates and FR4 circuit boards.
Aerospace: lossless slitting of titanium alloy honeycomb structures and composite materials.
4. Usage restrictions and precautions
Inapplicable materials:
Ferrous metals (steel, iron, etc.), due to the graphitization reaction of diamond and iron elements at high temperatures, resulting in edge collapse.
Operation requirements:
A cooling system (such as spray cooling) is required to prevent overheating, especially during continuous cutting.
The equipment needs to have high rigidity (such as CNC sawing machine) to ensure cutting stability.
V. Comparison with other materials
vs. Carbide saw blades: PCD has a longer life, but the initial cost is 2-3 times higher, suitable for high value-added product processing.
vs. High-speed steel saw blades: PCD has better heat resistance, can withstand higher cutting speeds, and reduce material thermal deformation.
Summary: PCD circular saw blades are ideal for processing difficult materials, especially for precision cutting scenarios of non-ferrous metals, composite materials and high-density non-metals. Correct selection and use can significantly improve production efficiency.
