Selection of saw blade teeth and advantages of saw blade coating for fully automatic high-speed metal circular saw machine
1、 Accurate selection of teeth for high-speed circular saw blades (suitable for fully automatic cold saws/high-speed circular saw machines)
1. Classification of tooth count
Coarse teeth (few teeth): 24T/30T/36T
Middle teeth: 40T/48T/50T
Fine teeth (dense teeth): 60T/72T/80T/100T
2. Select by cutting material (core)
Carbon steel, 45 # steel, round steel, solid bulk
Choose 30T-48T coarse/medium teeth, fast chip removal, less prone to tooth burning, impact resistance, suitable for fully automatic continuous feeding.
Stainless steel, alloy steel, high hardness steel
Choose 36T-50T medium coarse teeth, with not too many teeth to avoid excessive load on the tooth tip and tooth breakage.
Aluminum rod, copper material, soft metal
Choose 60T-80T dense teeth, with smooth and burr free incisions and flat cutting surfaces.
Thick walled steel pipe
40T-50T medium teeth, balancing efficiency and sectional quality.
Thin walled steel pipe, thin tube, thin profile
More than 60T dense teeth to prevent edge breakage and material hanging during cutting.
3. Select according to processing conditions
High speed fast cutting, batch rough cutting: few teeth
Precision cutting, smooth end face without burrs: multi tooth
Fully automatic feeding continuous mass production: Priority is given to 40-50T universal middle teeth, with the strongest universality
Short cutting and high-precision processing: using dense teeth
4. Simple mnemonics
Use fewer teeth for large hard materials and dense teeth for thin soft materials;
Quick cutting with coarse teeth, fine cutting with smooth and dense teeth.
2、 Common coating types and core advantages of circular saw blades
Mainstream coating types
TiN titanium nitride, TiAlN aluminum titanium nitride, black nitride coating, composite coating
Unified core advantages of coating
Strong high temperature resistance
Significantly reducing the high temperature generated by high-speed fully automatic cutting, avoiding softening of tooth tips during annealing, suitable for long-term continuous work.
Super wear-resistant, extending the life of the saw blade
The hardness of the coating far exceeds that of ordinary white sheets, with an increase in wear resistance of 30% -80%, reducing frequent replacement of sheets and lowering production costs.
Anti stick chips, non stick materials
Smooth surface without sticking iron or aluminum chips, with no burrs on the cut surface, eliminating the need for secondary trimming process.
Reduce cutting friction
Cutting is lighter and more efficient, saving energy and effort, reducing equipment load, and protecting the transmission structure of fully automatic machines.
rust and corrosion prevention
Warehousing and humid environments are less prone to rusting and can last longer.
Lower cutting noise and smoother operation
Suitable for fully automatic feeding and uniform cutting, improving the stability of the entire machine.
Applicable scenarios for different coatings
TiN gold coating
High cost-effectiveness, universal carbon steel cutting, preferred for daily mass production.
TiAlN purple black coating
The strongest resistance to high temperatures, the preferred choice for fully automatic high-speed continuous cutting, suitable for heavy loads and long-term non-stop operations.
Black nitride coating
The surface lubrication is excellent, with the best cutting effect on soft metals such as aluminum and copper, and the cut surface is super smooth.
