Band saw blade usage problem analysis (early wear solutions)

There are many reasons for early wear, and the specific reasons and solutions are as follows:

1. Sawing parameters:

A. Cutting speed is too high (Solution: slow down 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)

D. feed speed is too low(Solution: adjust the feed speed appropriately)

2. sawing machine reason:

A. Guide block, guide arm poor contact or wear(Solution: Replace the guide block)

B. The sawhorse jumps (shakes)(Solution: Check whether the feed cylinder enters the air, whether the oil quality changes, whether the cylinder is worn)

C. Machine vibration(Solution: Check the machine; Check for external sources)

D. Machine tool saw belt perpendicularity adjustment(Solution: adjust the verticality of the saw 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)

C. Improper concentration of cutting fluid(Solution: Adjust the concentration of cutting fluid)

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. Band saw blade is not run or run insufficiently(Solution: The band saw blade is properly run in)

C. Band saw blade stick, chip accumulation more(Solution: the band saw blade is properly run in; Select the correct sawing parameters; Select high quality cutting fluid and adjust the concentration)

D. Band saw blade rusted and corroded(Solution: Check whether the factory time is too long. Check whether the storage environment is humid)

E. Damage, injury or defect between teeth(Solution: Replace the band saw blade)

F. Band saw blade is not good for welding(Solution: re-weld or replace the band saw blade)

5. Sawing material:

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

B. material with hard points 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. Change the clamping method if necessary)
