How to Maintain the Saw of the CNC Pipe Cutting Machine?
ARCBRO is a leading CNC pipe cutting machine supplier in China. We would like to share professional knowledge and maintenance of CNC pipe cutting machines with the users. Today, we are going to teach you how to maintain the saw of the CNC pipe cutting machine.
1. If the saw no need to be used immediately, it should be placed flatwise or be hung up. Don’t put other objects or foot on the flat saw, and do good moisture protection and corrosion prevention.
2. When the saw is no longer sharp or the cutting surface becomes more and more rough, it must be promptly grinded. Never change the original angle or destroy the dynamic balance when grinding.
3. The diameter correction and positioning hole processing must be carried out by the manufacturer. Improper processing will affect the product using effect, and may be dangerous. The reaming should not exceed 20mm of the original diameter in principle, so as not to affect the stress balance.
4. Selection of 4 alloy grinding wheels.
1) The bonding strength of the resin bonded diamond grinding wheel is weak, so it has good self sharpening when grinding, no blockage, high grinding efficiency, little grinding force, low grinding temperature. The disadvantage is the poor wear resistance, abrasive loss, not suitable for heavy duty grinding.
2) The wear resistance and bonding ability of ceramic bonded diamond grinding wheel is better than the resin one, sharp cutting, high grinding efficiency, not easy blockage and heating. The thermal expansion quantity is small, so that it is easy to control the accuracy. The disadvantages are coarse grinding surface and high cost.
3) The bonding strength of the metal bonded diamond grinding wheel is high, good wear resistance, low wear, long life, low grinding cost, and it can bear larger load. But the Sharpness is poor and easy to plug.
4) The abrasive grain have a certain influence on the grinding blockage and cutting volume, coarse sand compares to fine sand, the biggest depth of cutting, the largest abrasive cutting edge weariness, otherwise the grinding wheel will be easy to plug.
5) The hardness of grinding wheel has great influence on clogging; the heat conductivity coefficient of the high hardness grinding wheel is high too, which is not conducive to surface heat radiation, but beneficial to improve the processing precision and durability.
6) The grinding wheel concentration selection is very important, which has a great impact on grinding efficiency and machining cost, too low concentration will affect the efficiency, whereas the abrasive grain is easy to fall off.
