When using the band saw machine and the band saw blade, it is inevitable to encounter faults. Some are caused by improper operation of the personnel, and some are caused by the problems of the band saw machine and the band saw blade itself. So how should we eliminate and deal with them?
Common sawing failures caused by improper operation include rough cutting surface of the workpiece, oblique cutting surface of the workpiece, fracture of the saw blade, tooth seizure of the saw blade, idling and slipping of the saw machine, squealing during sawing, etc. Usually, it is because the operator of the band saw machine has not adjusted the feed rate properly, the cutting speed makes the load of the band saw machine and the band saw blade too large, the tooth selection of the saw blade is incorrect, the workpiece of different materials is not consistent with the range of the band saw blade after replacement, and the new saw blade is not running-in The saw blade was not replaced after the saw teeth were passivated, the cutting fluid of the band saw machine was improperly mixed, and the band saw machine was not cleaned in place, and sawdust accumulated. The solution is as follows: the band saw machine must be idle and debugged every day when working, and the trial cutting can be started after confirming that the band saw machine and the band saw blade are in good working condition. During the trial cutting, the feed rate and the cutting speed of the saw blade should be properly adjusted, and the overall cleaning of the band saw machine should be done every day. After replacing the workpiece of other materials and sizes, the manufacturer of the band saw blade should be consulted to see whether this type of saw blade can adapt to the sawing of new parts. 90% of the failures of the band saw machine are caused by improper manual operation, Therefore, do not cut blindly and carelessly after the band saw machine is started.
The failures of the band saw machine itself are mostly due to the aging or inflexibility of the parts of the band saw machine that are not replaced or regularly inspected and maintained, such as unstable lifting, automatic lowering of the lifting cylinder cannot be stopped, failure of the speed control valve, foreign matter or air in the hydraulic cylinder, shaking of the band saw machine, oil leakage of the oil cylinder, failure of the solenoid valve, loosening of screws, etc, The solution is: if you have no knowledge and experience in the maintenance of the band saw machine, you should find the maintenance personnel in time or consult the band saw machine manufacturer in time when the above problems occur.
