Precision cutting saws: When working, the workpiece should be fixed, the profile positioning should conform to the direction of the knife, so as to avoid abnormal cutting, do not apply side pressure or curve cutting, the feed should be smooth, avoid the blade impact contact with the workpiece, resulting in The saw blade is broken, or the workpiece is flying out, and an accident occurs. When working, if the sound and vibration are abnormal, the cutting surface is rough, or the odor is generated, the operation must be terminated immediately, and the fault should be checked in time to eliminate the accident to avoid accidents. When starting cutting and stopping cutting, do not feed the knife too fast to avoid broken teeth and damage. If cutting aluminum alloy or other metals, use a special cooling lubricant to prevent the saw blade from overheating, causing paste, and other damage, which affects the quality of the cut. Equipment chip flutes and slag suction devices ensure smooth flow to prevent slag from forming into blocks, affecting production and safety. When dry cutting, please do not cut continuously for a long time, so as not to affect the service life and cutting effect of the saw blade; wet film cutting should be cut with water to prevent leakage.
Precision Panel Saw Blade Maintenance:
If the saw blade is not used immediately, it should be laid flat or suspended by the inner hole. The flat saw blade should not be stacked with other objects or feet, and should be protected against moisture and rust. When the saw blade is no longer sharp and the cutting surface is rough, it must be repaired in time. Grinding does not change the original angle and destroys the dynamic balance. The inner diameter correction of the saw blade, the positioning hole processing, etc. must be performed by the factory. If the processing is poor, it will affect the product use effect, and may be dangerous. In principle, the reaming should not exceed the original aperture of 20mm, so as not to affect the balance of stress.
The choice of alloy grinding wheel.
The precision of the precision panel saw is weak, so the self-sharpness can be good during grinding, it is not easy to block, the grinding efficiency is high, the grinding force is low, the grinding temperature is low, the disadvantage is that the wear resistance is poor, the wear loss is large, Suitable for heavy duty grinding. The ceramic bond diamond grinding wheel has better wear resistance and bonding ability than the resin binder. It has sharp cutting, high grinding efficiency, no heat and clogging, less thermal expansion, easy control precision, and has a rough grinding surface and high cost. The metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long service life, low grinding cost, and can withstand large loads, but has poor sharpness and is easy to block. The abrasive grain size has a certain influence on the clogging and cutting amount of the grinding wheel. Compared with the fine sand grain, the coarse sand grain has a larger cutting edge wear resistance, and the grinding wheel is easy to block the hardness of the grinding wheel, which has a greater influence on the blockage. The high hardness of the grinding wheel has a high thermal conductivity. Not conducive to surface heat dissipation, but it is conducive to improve processing accuracy and durability. Grinding wheel concentration selection is an important characteristic, which has a great influence on grinding efficiency and processing cost. If the concentration is too low, the efficiency is affected. On the contrary, the abrasive particles are easy to fall off, but the optimal binder concentration range is also the best.
Carbide saw blades are the most commonly used cutting tools for wood products. The quality of carbide saw blades is closely related to the quality of processed products. Proper and reasonable selection of carbide saw blades is of great significance for improving product quality, shortening cycle time and reducing processing costs.
The carbide saw blade includes various types of alloy cutter head, material of the base, diameter, number of teeth, thickness, tooth shape, angle, and diameter. These parameters determine the processing capability and cutting performance of the saw blade. When selecting a saw blade, the saw blade should be selected according to the type of sawing material, the thickness, the speed of sawing, the direction of sawing, the feeding speed, and the width of the sawing.
whose payload capacity is as much as 2000kg, lifting speed can reach up to 96m/min, and the erection height reaches up to 350m., our products have been widely used for transportation for both men and cargo in field of general buildings, but also industry, electric power, mining well, oil, chemical industry etc.
