There are several reasons for the phenomenon of tooth breakage in the process of using saw blade. How to solve this problem?

Check the tape first Sawing machine Reasons: especially for band sawing machines, the foundation bolts of the sawing machine may be loose, which may lead to the vibration of the saw frame. The bimetallic saw blade will suffer from non-standard vibration during cutting, which will cause tooth breakage. Check whether the lifting cylinder is worn, the oil quality is not good, or the air enters into the air, etc., which will cause the saw frame not to descend synchronously, the guide block on the guide seat is seriously worn, and the machine saw blade cannot be cut vertically normally, which will cause tooth breakage.

The second is the influence of improper tooth shape selection: no matter the metal being cut is solid, pipe material or special-shaped material, the feed speed and linear speed are not adjusted well, the tooth pitch selection is wrong, and there will be tooth breakage when using coarse teeth to cut small workpieces. After years of maintenance experience, we know that most of the faults are caused by improper operation. The new saw blade does not run in, the bimetal band saw blade does not contact the workpiece smoothly, and the tooth tip is damaged instantaneously when cutting hard steel. The operator should not be careless, and the workpiece must be clamped before cutting. If the workpiece is loose during cutting, the band saw blade will suffer from the uncertain external force and cause tooth breakage.

The use of appropriate concentration of coolant has good lubrication effect, greatly reducing the friction between bimetallic band saw blade and material. At the same time, the cooling liquid of sawing machine has the function of cooling and assisting chip removal. Turn on the circulating working water pump of cooling liquid of band sawing machine, speed up the mixing of liquid evenly, and then process after the cutting fluid is completely dissolved in water.

The coolant plays an important role in improving the working efficiency of the sawing machine. The coolant can efficiently remove metal scraps. The raw material is pure natural vegetable oil, which has strong cooling and anti rust functions.

When purchasing the cooling liquid of sawing machine, the machining enterprises are deeply aware that it is the key to reduce the enterprise cost to select the appropriate coolant to achieve good cooling effect. Through the flow of liquid to remove the chip, a long time, the filter will have a waste accumulation phenomenon, so it is necessary to regularly remove the particles in the filter, so as to improve the surface finish of the workpiece. For different customer groups, the company is equipped with two types of cooling products, namely cutting paste and cutting fluid. The cutting paste is low cost, light yellow, convenient for storage and transportation, suitable for rough machining. The cutting fluid for band saw machine is suitable for high-precision processing requirements and can improve the surface finish of the workpiece. The dilution ratio is 1:15 or 20. The metal cutting grade is up to grade, and the processing cost is reduced.
