Band saw blade usage problem analysis (vibration noise solution)

Band saw blade usage problem analysis (vibration noise solution)

There are many reasons for vibration and noise, and the specific reasons and solutions are as follows:

1. Sawing parameters

A. The cutting speed is too high (solution: reduce the cutting speed appropriately)

B. Improper selection of feed pressure (Solution: adjust feed pressure)

C. The feed speed is too high (solution: appropriately reduce the feed speed)

2. Sawing machine reason

A. The guide arm spacing is too large (solution: make the guide arm as close as possible to the workpiece)

B. Too much tension (appropriately reduce 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 jump (shake) movement (Solution: check whether only the feed cylinder enters the air, whether the oil quality changes, whether the cylinder is worn)

F. Poor contact between band saw blade and saw wheel edge (Solution: check or even replace saw wheel)

G. machine vibration (Solution: check the machine; Check for external sources)

3. cutting fluid

A. Improper selection of cutting fluid (Solution: replace cutting fluid)

B. Cutting fluid flow is too small, insufficient cooling (solution: increase the flow, adjust the water outlet so that the cutting fluid flows into the incision)

C. Improper concentration of cutting fluid (adjust the concentration of cutting fluid)

4. Saw blade selection

A. band saw blade type, tooth shape improper selection (solution: according to the workpiece material, shape choose the appropriate tooth shape)

B. Band saw blade sticky ruler, chip accumulation tumor (Solution: the band saw blade for correct run-in; Select the correct sawing parameters; Select cutting fluid and adjust the concentration)

C. Band saw blade is rusted and corroded (replace band saw blade)

D. Band saw blade greater than the wear limit (solution: replace the band saw blade)

E. Damaged, damaged or defective tooth tip (Solution: replace band saw blade)

F. Bad band saw blade to the welding joint (Solution: re-welding or replace the band saw blade)

5. Sawing materials

A. Sawing material material unknown (Solution: find out the material, and then select the correct sawing parameters for sawing)

B. material has a hard point or surface hardening (Solution: surface hardening materials need to adjust the 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. Change the clamping method when needed)
