Electric circular saw is a kind of power tool, it is powered by a single-phase series excitation motor, and then drives the circular saw blade through the transmission mechanism to perform the sawing operation. Electric circular saw is safe, reliable, reasonable structure, high work efficiency, suitable for wood, fiberboard, plastic and flexible cables and similar materials for sawing operations. Let's take a look at what makes a circular saw? What are the differences between circular saws and marble machines?
　　 What brand of electric circular saw is good?

　　 What are the differences between circular saws and marble machines?
The marble machine is cutting stone, and the electric circular saw is cutting wood.
The main purpose of designing a marble stone machine is to use brittle and hard materials such as stone, and it is necessary to use a diamond saw blade. The cutting amount of these brittle materials is small, and the only way to increase the cutting speed is to increase the rotational speed of the blade. The speed of the marble machine is more than 10,000 revolutions.
Electric circular saws are mainly designed for soft materials such as wood, and use woodworking saw blades such as high-carbon steels and alloy steels, while soft materials for cutting wood require a large amount of torque and therefore require a large torque. The speed of the circular saw design is around 5000 rpm to get a larger torque. Therefore, the main difference between the marble machine and circular saw is that the design purpose is different and the speed is different.
At the same time, the sawing disk of the marble machine is too small. When the wood material is cut, the turning surface is too high and the cutting surface burns. If you encounter nails or hard boring while cutting, you will also rebound. At the same time, the directions of the marble stone saw and the electric circular saw are different, and the direction of the hand-held saw is different. Of course, if you use electric circular saws to cut hard objects such as stone, tiles, etc., it would be even more infeasible, because the electric circular saws cannot reach the corresponding force of profile cutting, and forced use will only lead to burning.
The structure of the electric circular saw is outside the climbing type and is mainly composed of a motor, a gear box, a protective cover, an adjustment mechanism and a bottom plate, a handle, a switch, a non-rewirable plug, and a circular saw blade. The above is a good brand of electric circular saw? What are the differences between circular saws and marble machines? The entire contents of the electric circular saw is a power tool, and it will have a certain degree of danger, so everyone must be sure to see the brand and product information when selecting a circular saw.
