There are many reasons for breaking edge tooth pulling, the specific reasons and solutions are as follows:
1. Sawing parameters:
A. The cutting speed is too low(Solution: Adjust the sawing speed appropriately)
B. Improper selection of feed pressure(Solution: Adjust the feed pressure)
C. 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. 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)
F. The vise is not tightly clamped and the mouth surface of the vise is not good(Check the vise, trim the jaw surface or even replace the jaw)
G. Machine vibration(Solution: Check the machine; Check for external sources)
H. drive wheel belt slip(Solution: check the drive belt)
3. Cutting fluid:
A. Improper selection of cutting fluid(Solution: Replace the cutting fluid)
B. Cutting fluid flow is too small, insufficient cooling(Solution: increase the flow rate, adjust the water outlet so that the cutting fluid flows into the incision)
4. 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. The band saw blade is not running-in or running-in is insufficient(Solution: The band saw blade is properly run in)
C. Band saw blade sticky ruler, chip accumulation(Solution: the band saw blade is properly run in; Select the correct sawing parameters; Select cutting fluid and adjust the concentration)
D. Band saw blade greater than the wear limit(Solution: Replace the band saw blade)
E. The tip of the tooth is damaged, damaged or defective(Solution: Replace the band saw blade)
F. The band saw blade is not good to the welding joint(Solution: re-weld or replace the band saw blade)
5. Sawing materials:
A. The sawing material is unknown(Solution: figure out the material, and then select the correct sawing parameters for sawing)
B. The material has a hard point or surface hardening(Solution: surface hardening materials need to adjust parameters. Reduce belt speed and feed speed when hard points are encountered)
C. Sawing material stiffness is too poor
Solution: Choose the right band saw blade. Sawing is performed under appropriate sawing parameters. Need time to change the clamping method)
D. Material irregularities affect clamping (change the clamping mode to ensure material clamping)
E. Cut off finished product entanglement (timely removal of sawdust)
