Saw blade category:

  1. a saw blade for metal cutting of stone;

  2. High-speed steel saw blade for cutting (not embedded with carbide tip);

  3. Carbide saw blades and diamond saw blades for cutting solid wood, furniture, wood-based panels, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel, etc.

 

Various saw blade teeth:

①Acrylic class:

(The fine-cut tooth type is selected from the left and right sides and is simply indicated by the letter BA5)

 

②Aluminum category:

(Tooth type selects flat teeth, durable and wear-resistant, not easy to break teeth, simply indicated by the letter BT)

 

③Solid wood category:

(The number of teeth of the fine-cut saw blade should be denser. The tooth type is selected from the left and right sides and is simply indicated by the letter BA5; the material is suitable for the small-tooth saw blade, and the tooth type is selected by the letter BC.)

 

④Panel furniture and custom furniture:

(The number of teeth of the fine saw blade should be denser, the tooth shape should be selected from the left and right sides and the letter BA5 is simple; the material is suitable for the small tooth saw blade, and the tooth type is selected by the letter BC. The electronic cutting saw in the custom furniture. According to the size of the saw blade of each manufacturer, the size and angle of the saw blade are used.)

 

 

 

Basic parameters of the saw blade:

Carbide saw blades contain many parameters such as alloy cutter head, base, diameter, number of teeth, thickness, tooth shape, angle, and diameter. These parameters determine the processing capability and cutting performance of the saw blade. When selecting a saw blade, the saw blade should be selected according to the type, thickness, sawing speed, sawing direction, feeding speed and sawing width of the sawing material.

Outer diameter:

The outer diameter of the saw blade is chosen to be related to the sawing equipment used and the thickness of the sawn workpiece. The outer diameter of the saw blade is small, and the cutting speed is relatively low; the outer diameter of the saw blade is high for the saw blade and the sawing device, and the sawing efficiency is also high. The outer diameter of the saw blade is selected according to the different circular saw model. Standard outer diameters are: 110MM (4 inch), 150MM (6 inch), 180MM (7 inch), 200MM (8 inch), 230MM (9 inch) 20MM (10 inch), 300MM (12 inch), 350MM (14 Inch, 400MM (16 inch), 450MM (18 inch), 500MM (20 inch), etc., the bottom slot saw blade of precision panel saw is designed to be 120MM.

 

Number of teeth:

Number of teeth: The choice of the number of teeth, generally speaking, the more the number of teeth, the more cutting edges per unit time, the better the cutting performance, but the number of cutting teeth requires a large number of hard alloys, the price of the saw blade is high, but the sawtooth Too dense, the amount of chip between the teeth becomes smaller, which is easy to cause the saw blade to heat up; in addition, there are too many serrations. When the feed amount is improperly matched, the amount of cutting per tooth is small, which will aggravate the friction between the cutting edge and the workpiece, affecting the blade. Service life. Usually the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected according to the processing method of the sawing material.

 

Alloy thickness (saw road):

 The thickness of the selected blade thickness is theoretically we hope that the thinner the blade, the better, the kerf is actually a kind of consumption. The material of the alloy saw blade base and the process of manufacturing the saw blade determine the thickness of the saw blade, the thickness is too thin, and the saw blade is easy to shake when working, which affects the cutting effect. The thickness of the saw blade should be chosen from the stability of the saw blade work and the material being sawed. The thickness required for some special-purpose materials is also specific and should be used as required by the equipment.

 

Tooth type:

Commonly used tooth shapes include left and right teeth, ladder flat teeth, left and right flat teeth, left and right flat teeth, and humpback teeth.
 
1. The left and right teeth (BC/ATB) are the most widely used, with fast cutting speed and relatively simple grinding. Suitable for cutting and cross sawing various soft and hard solid wood profiles and MDF, multi-layer boards, particle board and so on.
 
2, left and right flat teeth (BA3) mainly assist in chip removal, mostly used for slotting and sawing flat bottom.
 
3, left and right flat teeth (BA5) is mainly formed, the number of teeth is dense, suitable for solid wood, photo frame, acrylic fine cut
 
4. The flat tooth (BT/TCG) is a combination of trapezoidal teeth and flat teeth. It is more complicated to repair and can reduce the cracking of the veneer when sawing. It is suitable for sawing of various single and double veneer wood-based panels and fireproof panels. In order to prevent adhesion, the aluminum saw blade also uses a saw blade having a large number of teeth of the flat teeth.
 
5, humpback teeth (FT) is a flat tooth equipped with anti-rebound force protection teeth, suitable for longitudinal cutting of various tree-shaped boards
