Hard Alloy Saw Blades

Hard alloy saw blades include multiple parameters such as the type of alloy blade, material of the substrate, diameter, number of teeth, thickness, tooth shape, angle, aperture, etc. These parameters determine the machining ability and cutting performance of the saw blade. When selecting a saw blade, it is necessary to select it correctly based on the type, thickness, cutting speed, cutting direction, feeding speed, and sawing path width of the sawing material.
（1） The commonly used types of hard alloys include tungsten cobalt (code YG) and tungsten titanium (code YT). Due to the good impact resistance of tungsten cobalt based hard alloys, they are more widely used in the wood processing industry. The commonly used model in wood processing is YG8-YG15. The number behind YG indicates the percentage of cobalt content. With the increase of cobalt content, the impact toughness and Flexural strength of the alloy have improved, but the hardness and wear resistance have decreased. It should be selected according to the actual situation.
（2） Selection of matrix
65Mn spring steel has good elasticity and plasticity, material economy, good heat treatment hardenability, low heating temperature, and easy deformation, which can be used for saw blades with low cutting requirements.
2. Carbon Tool steel has high carbon content and high thermal conductivity, but its hardness and wear resistance drop sharply when subjected to the temperature of 200 ℃ -250 ℃. It has large deformation during heat treatment, poor hardenability, and is easy to crack when tempered for a long time. Manufacturing economic materials such as T8A, T10A, T12A, etc. for cutting tools.
3. Compared with carbon Tool steel, alloy Tool steel has good heat resistance, wear resistance and treatment performance. The heat-resistant deformation temperature of 300 ℃ -400 ℃ is suitable for manufacturing high-grade alloy circular saw blades.
4. High speed Tool steel has good hardenability, strong hardness and rigidity, less heat resistance and deformation, and belongs to ultra-high strength steel. Its thermoplastic stability is suitable for manufacturing high-grade ultra-thin saw blades.
（3） The selection of diameter is related to the sawing equipment used and the thickness of the sawing workpiece. The diameter of the saw blade is small, and the cutting speed is relatively low; The large diameter of the saw blade requires high requirements for the saw blade and cutting equipment, as well as high cutting efficiency. The outer diameter of the saw blade should be selected based on different circular saw machine models, and the saw blade with the same diameter should be used. The diameters of standard parts include: 110MM (4 inches), 150MM (6 inches), 180MM (7 inches), 200MM (8 inches), 230MM (9 inches), 20MM (10 inches), 300MM (12 inches), 350MM (14 inches), 400MM (16 inches), 450MM (18 inches), 500MM (20 inches), etc. The bottom groove saw blades of precision cutting saws are mostly designed as 120MM.
（4） The selection of tooth number: Generally speaking, the more teeth there are, the more cutting edges there are per unit time, and the better the cutting performance. However, if there are more cutting teeth, a larger amount of hard alloy is required, resulting in a higher price for the saw blade. However, if the teeth are too dense, the chip capacity between the teeth becomes smaller, which can easily cause the saw blade to heat up; In addition, there are too many serrations, and if the feed rate is not properly matched, the cutting amount per tooth is very small, which will exacerbate the friction between the edge and the workpiece and affect the service life of the blade. Usually, the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected based on the material being sawn.
（5） The selection of thickness. In theory, we hope that the thinner the saw blade, the better. The saw gap is actually a consumption. The material of the alloy saw blade substrate and the manufacturing process of the saw blade determine the thickness of the saw blade. If the thickness is too thin, the saw blade is prone to shaking during operation, which affects the cutting effect. When selecting the thickness of the saw blade, consideration should be given to the stability of the saw blade operation and the material used for sawing. Some special purpose materials require specific thicknesses and should be used according to equipment requirements, such as grooving saw blades, marking saw blades, etc.
（6） The commonly used tooth shapes for tooth shape selection include left and right teeth (alternating teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted conical teeth), dovetail teeth (hump teeth), and rare industrial grade three left and one right, left and right flat teeth.

Hard Alloy Saw Blades: The Top Choice for Precision Cutting

Cutting is a fundamental process in the construction, woodworking, and metalworking industries, to name a few. It involves the separation of materials using tools such as saws, knives, and shears. Given the importance of precision, speed, and efficiency in cutting, the choice of tools is critical to achieving quality results. One of the most popular choices in the cutting industry today is the hard alloy saw blade, a versatile and durable cutting tool that can cut through a wide range of materials with ease.

Overview of Hard Alloy Saw Blades

Hard alloy saw blades are made from a combination of tungsten carbide and cobalt or nickel binder. The tungsten carbide is a hard and brittle material that provides the blade's cutting edge, while cobalt or nickel bonds the tungsten carbide particles together to form a strong and stable structure. This combination results in a durable and wear-resistant saw blade that has exceptional cutting performance and long service life.

Hard alloy saw blades come in various sizes and shapes, designed to cut different materials, from wood and plastics to metals and ceramics. They offer fast and precise cutting with minimal kerf, reducing material waste and increasing productivity. They can also be used in a wide range of cutting machines, including circular saws, miter saws, table saws, and band saws, among others.
