What Is a Metal Cutting Circular Saw?

Circular saws are toothed tools used to cut steel. Metal circular saws can easily cut steel, just as easily as traditional 2x4's hoses. The circular saw uses a unique material and tooth profile. Compared to previous products, it cuts metal faster, has better chip handling capabilities, and does not transfer heat during the cutting process.

Compared to previous products, it cuts metal faster, has better chip handling capabilities, and does not transfer heat during the cutting process.

In the test, the average time required to cut a 6 "x1 / 4" steel plate with a circular saw blade was less than 12 seconds, and the average time to cut a 2 "x2-1 / 4" angle iron was less than 6 seconds. Circular saw blades range in diameter from 5-3 / 8 "to14" and are suitable for a variety of circular saw machines. The circular saw hard alloy blade is made of a mixture of tungsten carbide and titanium carbide, which can make the cutting process completely free of sparks and minimize the heat transmitted to the workpiece being cut, and the waiting time required during the cutting process is also reduced.

Circular saws can be used with most professional circular saws, and if they are used in metal circular saws from manufacturers including MKMorse saw blades, the circular saw blades can exert their maximum effectiveness. Circular saw blades are a common cutting tool and are widely used in wood processing and metal cutting. During the use of the circular saw blade, the indicators or factors that affect its stability and effectiveness include silver wear, high-speed stability and cutting accuracy. Circular saw blades are divided into 5 cutting categories: steel, ultra-thin steel, stainless steel, aluminum and wood. The different types of saw blades differ in the number of teeth, the shape of the teeth, and the angle of the teeth. The teeth of cutting steel and ultra-thin steel circular saw blades have a zero-degree angle, while circular saw blades for cutting aluminum, stainless steel and wood have positive front teeth.

During the use of the round pieces, the external environment and external forces will deform the structure of the material when it is used under high temperature and high speed conditions. The ability of the material to resist this deformation is the stability ability. Under the action of stress, the more difficult it is to deform, the more stable it is. When the applied load is within a certain range, under the action of the applied load, the wrong piece will deviate from the equilibrium state. The initial state is said to be stable. When the applied load exceeds this range, when the applied load is removed, the piece cannot return to the original state, and the wrong piece is said to be unstable.

A phenomenon in which a component loses its ability to maintain a stable equilibrium configuration is called instability or buckling. There are two kinds of instability mechanisms of round silver tablets:

One is instability under critical loads, that is, buckling caused by external forces or loads exceeding the material's own resistance limit. Rigidity represents the relationship between the applied load and the deformation that occurs when the load is received. It can be seen that the static bending instability is mainly related to the rigidity of the disc.

The second is the critical speed instability. When the rotation speed of the film reaches the critical rotation speed of the material collection itself, a large change in the material structure and the like will cause its own performance to deteriorate or change. According to related research, the speed instability of the film is mainly related to its structure, stress conditions, and the external environment. The self-structure mainly includes the thickness and diameter of the silver sheet, the stress conditions mainly include the stress, thermal stress, and tensile stress, etc., and the external environment mainly includes the lubrication conditions, high temperature conditions, and the parameters and configuration of cutting lead ^[2]

Woodworking circular saw blade is the basic tool for wood processing. It has the advantages of high efficiency, simple use, convenient maintenance, and convenient movement. It accounts for 30% to 40% of all wood production equipment. Relevant research institutions at home and abroad have attached great importance to the study of woodworking circular saw blades. Reducing its thickness and increasing its stability are recognized at home and abroad as the most effective method to improve the utilization rate of wood processing. Therefore, ultra-thin woodworking circular saw blades are more and more popular in the market and are widely used in the field of wood processing.

The main factors affecting the working performance of woodworking circular saw blades include the centrifugal stress it generates under high-speed rotation and the thermal stress generated during the cutting process. As the temperature difference between the outer edge of the woodworking circular saw blade and the vicinity of the chuck further increases, the tangential compressive stress generated by the thermal stress on the outer edge of the woodworking circular saw blade will continue to increase, gradually exceeding the The tangential tensile stress makes the total tangential stress of the outer edge of the woodworking circular saw blade appear compressive stress. This will cause buckling deformation and instability of the outer edge of the saw blade under the action of a small lateral force, resulting in reduced sawing accuracy and quality of the machining surface, increased saw path loss, further increased cutting heat, and shortened saw blade life. problem. These problems become more prominent with the thinning of woodworking circular saw blades, which brings great difficulties to the manufacture, use and maintenance of ultra-thin woodworking circular saw blades. For this reason, the commonly used method is to perform a proper treatment on the woodworking circular saw blade, that is, to make a certain degree of plastic deformation in the local area of the saw blade by mechanical or physical means, and then introduce appropriate numerical values and reasonable distribution inside the saw blade. Pre-stress field to compensate for the unfavorable cutting thermal stress generated by the woodworking circular saw blade during the cutting process, thereby achieving the purpose of improving the stability and quality of the saw blade ^[3] .
