Cutting and non-cracking of the Alec saw blade for use and maintenance requirements - Dongguan Yibao Knife Saw Factory cutting non-cracking Alec saw blade for use and maintenance requirements - Dongguan Yibao Knife Saw Factory
Alec saw blade process characteristics without collapse
1. Polymethyl methacrylate contains a polar side methyl group, which has obvious hygroscopicity. The water absorption rate is generally 0.3%-0.4%. It must be dried before molding. The drying condition is drying at 80 ° C-85 ° C for 4-5 h. .
2. Polymethyl methacrylate has obvious non-Newtonian fluid properties in the temperature range of molding processing. The melt viscosity decreases with the increase of shear rate, and the melt viscosity is also sensitive to temperature changes. Therefore, for the molding process of polymethyl methacrylate, increasing the molding pressure and temperature can significantly reduce the melt viscosity and achieve better fluidity.
3. The temperature at which polymethyl methacrylate starts to flow is about 160 ° C, and the temperature at which decomposition begins is higher than 270 ° C, and has a wide processing temperature interval.
4. Polymethyl methacrylate has a high melt viscosity and a fast cooling rate, and the product is prone to internal stress. Therefore, the control of the process conditions is strict during molding, and post-treatment is also required after the product is formed.
5, polymethyl methacrylate is an amorphous polymer, the shrinkage rate and its range of variation are small, generally about 0.5% -0.8%, which is conducive to the formation of plastic parts with higher dimensional accuracy.
6. Polymethyl methacrylate has excellent cutting performance, and its profiles can be easily machined to various required sizes.

Alec saw blade requirements for use
1. 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 saw blade damage, or workpiece Flying out, an accident occurred.
2. 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.
3. When starting cutting and stopping cutting, do not feed the knife too fast to avoid broken teeth and damage.
4. If cutting aluminum alloy or other metal, use a special cooling lubricant to prevent the saw blade from overheating, causing paste, and other damage, which affects the cutting quality.
5. Equipment chip flute and slag suction device ensure smooth flow to prevent slag from forming into blocks, affecting production and safety.
6. 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.

Maintenance requirements for Alec saw blades
1. If the saw blade is not used immediately, it should be laid flat or suspended by the inner hole. The other saw blades should not be stacked with other objects or feet, and should be protected against moisture and rust.
2. 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.
3. 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 danger may occur. The hole reaming should not exceed the original hole diameter of 20mm in principle, so as not to affect the stress balance.
4. Selection of alloy grinding wheels.
1) The resin bond diamond grinding wheel has weak bonding strength, so the self-sharpening property during grinding can be good, it is not easy to block, the grinding efficiency is high, the grinding force is low, the grinding temperature is low, and the disadvantage is poor wear resistance and wear loss. Large, not suitable for heavy duty grinding.
2) Ceramic bond diamond grinding wheel has better wear resistance and bonding ability than 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. .
3) Metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long service life, low grinding cost and high load, but poor sharpness and easy blockage.
4) 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 sanding grain has a larger wear depth of the cutting edge, and the grinding wheel is easy to block.
5) The hardness of the grinding wheel has a great influence on the blockage. The high hardness of the grinding wheel is high, which is not conducive to surface heat dissipation, but it is beneficial to improve the processing precision and durability. 6) The choice of grinding wheel concentration is an important characteristic. It has a great influence on the grinding efficiency and processing cost. If the concentration is too low, the efficiency will be affected. On the contrary, the abrasive particles will fall off easily, but the optimal binder concentration range is also the best.
