When the circular saw is cutting, if there is a loud abnormal sound, it may be caused by unstable factors in the saw blade or equipment of the circular saw, and the machine needs to be shut down for troubleshooting.

　　1. Analysis of abnormal sound caused by unstable circular saw equipment:

　　There are usually two situations that cause the equipment to make an abnormal sound, one is the "warning" caused by the problem of the equipment itself, and the other is the unstable factor caused by the saw blade in the cutting process;

　　1. The performance of the circular saw is unstable

　　After the equipment has been used for a period of time, regular maintenance is required. If the implementation of these tasks is not arranged, the aging of the equipment will be accelerated, resulting in unstable performance, that is to say, the incoordination between various accessories. This situation The operation of the lower circular saw will be overloaded, and the compatibility between the accessories will not be buffered. When working at high speed, it will make an abnormal sound. This is a warning signal. If it is not improved, it will be Seriously affect the follow-up work of the equipment; about the maintenance of the circular saw machine, please refer to the official website of Jingweite: "Daily Maintenance of High-speed Circular Saw Machine"

　　2. The accessories are incomplete

　　The accessories of the circular sawing machine also have a certain service life. If the specified time is exceeded and the repair is not performed in time, it will cause vibration during work, which will cause loud noises. The equipment should be regularly inspected to ensure that each The normal use of the configuration.

　　3. The screws of some parts are loose or dropped

　　When the circular saw machine is working, it runs at a high speed. After a period of operation, it is inevitable that the screws of some parts will loose or fall. If you find that there is a slight shaking during sawing, Inspection should be carried out in time, or when the sound of iron impact is heard during the cutting process, the operation must be stopped immediately and related inspections and repairs should be carried out.

　　4. The clamping block is not clamped

　　When the equipment is cutting, there is a clamping block to clamp the material to be sawed. If the cutting work is not clamped, it will cause a louder noise and damage the saw blade and equipment accessories.

　　2. The abnormal sound produced by the instability of the saw blade of the circular saw

　　The main working part of the circular saw machine is the saw blade. If the saw blade is unstable, the first time it will make an unusual sound. First of all, we can check whether the magnetic powder clutch is normal.

　　A. There is a foreign body in the saw tooth part of the saw blade

　　When the circular saw machine is running at high speed, the sawdust will enter the slit of the saw blade head because it is not discharged in time. This will cause the saw teeth to not be in good contact with the metal material during the cutting process, resulting in abnormal sound. This situation must be eliminated immediately, otherwise it will seriously threaten the use of the saw blade, and even cause cracks or chipping.

　　B. The saw blade needs to be sharpened

　　The saw blade has a certain use time. When it is used, it must be replaced. If it is not replaced in time, it will cause the quality of the cut workpiece to decrease, and the abnormal noise caused by the dull part of the saw tooth.

　　For some common problems and treatment of saw blades, you can refer to the official website of Jingweite: "Factors and Solutions for Severe Wear of Circular Saw Blades During Work" Dongguan Jincheng Machinery Co., Ltd. is engaged in metal pipes, bars, profiles and plates It has been processing for more than 20 years, integrating design and development, manufacturing and sales services, forming a series of products with precision metal circular sawing machine, round tube rod end chamfering, tube bending forming, saw blade grinding and other series of products as the main operating axis The operation system, products are widely used in automobiles, motorcycles, bicycles, baby carriages, metallurgy, shipbuilding, medical, lighting, solar energy, IT electronics, metal furniture, building doors and windows, hardware sanitary ware, health care equipment, wind power generation, air conditioning and refrigeration and many other industries And fields.
