In order to ensure that the normal operation of the band sawing machine will not affect the production efficiency of the enterprise and ensure the service life of the band sawing machine, attention should be paid to troubleshooting the common failures of the band sawing machine in daily use. In fact, most of the problems can be avoided by the band sawing machine operator’s frequent inspection and replacement of consumable parts. The following is a summary of common problems and solutions of band sawing machine for your reference.
1、 Avoid accumulation of foreign matters
Before going off duty, remove sawdust, dust, oil stain, loosen the saw band, regularly remove the relevant covers, wipe the internal parts, and conduct deep cleaning to prevent rust and corrosion. If the cleaning is not in place, foreign matters will accumulate, and the next operation may be blocked or jammed, causing serious damage to the band saw machine and band saw blade.
2、 Saw blade cracking, tooth beating and tooth breakage
Saw blade problems are usually related to tension, tooth shape discrepancy, excessive load of the saw blade, etc. It is necessary to check one by one whether it is the quality of the saw blade or the improper operation of the personnel. With the development of technology, the current intelligent CNC band sawing machine on the market can automatically make appropriate adjustments to the change of the inductive force to avoid the failure loss caused by violent sawing and improper operation. If necessary, you can call for consultation.
3、 No tooth selection and no running in of new saw blade
According to the different hardness, thickness and size of the workpiece, confirm the tooth shape of the band saw blade as required. After replacing a new saw blade, it is necessary to run in. During the running in, adjust the slow feed to remove the burrs on the serrations. After the serrations are smooth, perform normal sawing.
4、 The sawing machine is not flexible
Daily check the hydraulic oil, coolant and lubricating oil of the band sawing machine to ensure adequate supply. Secondly, the quality, cleanliness and viscosity of the hydraulic oil play a leading role in the life of the hydraulic pump, hydraulic valve and hydraulic cylinder of the band sawing machine. Pay great attention to the quality and cleanliness of the hydraulic oil to avoid the inflexible operation of the band sawing machine due to insufficient lubrication or blocked hydraulic components.
5、 Sawing machine oscillation
There are many reasons that affect the vibration of the band sawing machine: too fast feed speed, improper tooth selection, loose saw blade, workpiece not clamped, hydraulic system failure, loose bolts and nuts, etc. The sawing machine should be inspected in all aspects, or reported to professional technicians for subsequent treatment.
