Hard alloy saw blade is the most commonly used blade of wooden products. The quality of the hard alloy saw blade is closely related to the quality of processing products.The correct and reasonable choice of hard alloy saw blades is of great significance for improving product quality, shortening processing cycle, and reducing processing costs.Lets take a look at what specifications of alloy saws?How should I buy it?
Alloy saw tablet classification
There are several categories and uses for alloy saw blades? If the saw blades are divided according to the material, there are roughly high -speed steel saw tablets (HSS saw blades, flying saw blades), overall hard alloy saw blades, inlaid alloy saw tablets (hard hardnessAlloy saw tablet), tungsten steel saw tablets, diamond saw tablets (including coating diamond), etc.
Speaking of alloy saw blades, according to the use of use, there are woodworking saw slices (cut wood, bamboo and other plant materials), sawdes (cutting stones, cement, etc.), metal processing saw blades (copper -cut aluminum cut stainless steel, stainless steel,Cut the color metal black metal, etc.), cut plastic saw blades (plastic, PVC, rubber, etc.), Cherlak saw blades (cut glass), etc.
Alloy saw size specification
Many people do not know enough about the knowledge of alloy saws, and they are not very clear about the outer diameter of the alloy saw blade.This makes it difficult to buy a saw blade.In fact, there are generally two sayings of the outer diameter of the saw blade.For example, one: One: Some people say that the 200mm outer diameter is 200mm in the outer diameter; two: If anyone says 8 inches of saw blades, it also means that it is a 200mm saw blade, because the inch here refers to the inch of inch of inch here.Essence(1 -inch = 25.4mm).This is the popular knowledge of the outer diameter of the saw film.
The diameter of the alloy saw blade refers to the diameter of the internal positioning hole inside the saw tablet.Generally speaking, the diameter of alloy saws is divided into two types: 25.4mm and 30mm.
Generally speaking, the 4 -inch to 10 -inch saweta pores are 25.4mm.More than 12 -inch is 30mm.Of course, more than 12 inches also have a saw blade with a pore diameter of 25.4mm.
The number of teeth refers to the number of alloy saws.The number of teeth of the general alloy saw blade is expressed in letters T. For example, 60T means 60 teeth.Generally, a saw blade with the corresponding tooth number according to cutting requirements and efficiency. Generally, the number of teeth that are commonly used is 30, 40, 60, 80, 100,120t.However, there are special number of teeth, such as 70 teeth and 96 teeth.
How to buy alloy saws
Hard alloy saw blade is the most commonly used blade of wooden products. The quality of the hard alloy saw blade is closely related to the quality of processing products.The correct and reasonable choice of hard alloy saw blades is of great significance for improving product quality, shortening processing cycle, and reducing processing costs.
Hard alloy saw blade contains the type of alloy header, the material, the material, diameter, number of teeth, thickness, thickness, tooth shape, angle, pores, and other parameters. These parameters determine the processing capacity and cutting performance of the saw blade.When selecting a saw blade, you must choose the saw blade correctly according to the type, thickness, thickness of the sawing, cutting cut, the direction of the saw, the speed of the feed, and the width of the saw path.
(1) Selection of hard alloy types
The types of hard alloy are tungsten cobalt (codenamed YG) and tungsten titanium (codenamed YT).Due to the good impact of tungsten cobalts hard alloy, it is more widely used in the wood processing industry.The models commonly used in wood processing are YG8-YG15. The numbers behind YG indicate the percentage of cobalt content. The cobalt content increases, the anti-punching toughness and curved strength of the alloy are increased, but the hardness and wear resistance decrease.Choose according to the actual situation.
(2) Selection of matrix
1. 65mn spring steel elasticity and plasticity, material economy, good thermal treatment, low heating temperature, easy deformation can be used to require a saw blade with low cutting requirements.
2. The high carbon-containing high heating rate of carbon tools is high, but the hardness and abrasion resistance decreased sharply at the temperature of 200 ℃ -250 ℃.Economic materials for tool manufacturing such as T8A, T10A, T12A, etc.
3. Compared with carbon tool steel, alloying tool steel is heat-resistant, good abrasion resistance, and good treatment performance. The heat-resistant deformation temperature is suitable for making high-end alloy round saw blades at 300 ° C-400 ° C.
4. High -speed tool steel has good quenchtability, strong hardness and rigidity, less heat -resistant deformation, which is ultra -high -strength steel.
(3) Selection of diameter
The diameter of the saw blade is related to the thickness of the saw -cutting equipment and the cutting -cut workpiece.The diameter of the saw tablet is small, and the cutting speed is relatively low; the large diameter of the saw tablet is high on the saw blade and the sawing device, and the cutting efficiency at the same time is also high.The outer diameter of the saw tablet is selected to use a diameter -consistent saw blade according to different circular saw machines.
(4) Selection of the number of teeth
The number of tooths of sawtooth, generally, the more teeth are, the more cutting the blade of the cutting in the unit time, the better the cutting performance, but the number of cutting teeth is large.The amount of containers between the teeth becomes smaller and easily causes sawing tablets. In addition, if there are too many sawtooth, if the amount of advancement is not proper, the amount of each teeth is small, which will exacerbate the friction between the blade mouth and the workpiece, which will affect the service life of the blade, which will affect the service life of the blade.EssenceUsually the spacing of the tooth is 15-25mm, and the number of teeth should be selected according to the material of the cutting cut.
(5) Selection of thickness
(6) Selection of tooth shape
Commonly used tooth shapes include left and right teeth (alternate teeth), flat teeth, gradient teeth (high and low teeth), inverted trapezoidal teeth (inverted teeth), sloppy teeth (hump teeth), and the rare industrial -grade double double double double double doubleThe dedicated San left, one, right, left, right, left, right, and other flat teeth.
1. The use of left and right teeth is the most extensive, the cutting speed is fast, and the grinding is relatively simple.It is suitable for various soft, hard wood profiles and density boards, multi -layer boards, particle boards, etc.The left and right teeth equipped with anti -relieving teeth are the tailor tail tooth, which is suitable for cutting various trees with various trees; the left and right tooth saw sheets with negative front angles are usually used for paste.Saw of the panel.
2. The flat tooth saw is rough, the cutting speed is slow, and the most simple it is to repair.It is mainly used for sawing cutting of ordinary wood. The cost is low. It is mostly used for aluminum with smaller diameter to keep the adhesion during cutting, or is used to keep the bottom of the slot flat.
3. The flat teeth are a combination of trapezoidal tooth and tooth. The grinding is more complicated. When cutting, it can reduce the phenomenon of the collapse of the surface. It is suitable for the sawn cut of various single -double -faced artificial panels and fireproof boards.In order to prevent adhesion, aluminum is also used to prevent the tap with more teeth with flat teeth.
4. Pour the gradient tooth is often used in the cutting bottom of the cutting bottom groove saw blade. When cutting and cutting the double -faced artificial board, the thickness of the slot adjustment of the slot is completed, and then the saw cutting of the plate was completed by the main saw to complete the saws of the plate, so as to use it to use it to process it.Prevent the phenomenon of collapse.
