There are many reasons for the rough saw section, and the specific reasons and solutions are as follows:
1. Sawing parameters
A. The cutting speed is too high
(Solution: Reduce the sawing speed appropriately)
B. The cutting speed is too low
(Solution: adjust the cutting speed appropriately)
C. Improper selection of feed pressure
(Solution: Adjust the feed pressure)
D. The feed speed is too high
(Solution: appropriately reduce the feed speed)
2. Sawing machine reason
A. The distance between guide arms is too large
(Solution: Make the guide arm as close to the workpiece as possible)
B. Not enough tension
(appropriately increase tension)
C. Poor contact or wear of guide block and guide arm
(Solution: Solution: Replace guide block)
D. Band saw blade running unstable
(Check the main drive, bearing and saw frame lifting structure)
E. The wire brush is improperly adjusted
(Solution: check and replace the wire brush)
F. Saw frame jumping (shaking) motion
(Solution: Check whether only the oil cylinder enters the air, whether the oil quality changes, whether the oil cylinder is worn)
G. The band saw blade is in poor contact with the edge of the saw wheel
(Solution: Check or even replace the saw wheel)
H. The vise is not fastened, and the mouth surface of the vise is poor
(Check the vise, trim the jaw surface or even replace the jaw)
I. Machine vibration
(Solution: Check the machine; Check for external sources)
J. Drive wheel belt slip
(Solution: check the drive belt)
3. Saw blade selection
A. Improper selection of band saw blade type and tooth shape
(Solution: Select the appropriate tooth shape according to the material and shape of the workpiece)
B. Damage, injury or defect between teeth
(Solution: Replace the band saw blade)
C. The band saw blade is not good to the welding joint
(Solution: re-weld or replace the band saw blade)
4. Saw the material
A. Sawing material stiffness is too poor
Solution: Choose the right band saw blade. Sawing is performed under appropriate sawing parameters. Change the clamping method if necessary)
B. Material irregularities affect clamping
(Change the clamping method to ensure that the material is clamped)
