Customer Feedback Issues

1. Current Saw Blade Condition:

   • Compared to previous saw blades, the current blade’s performance is poor, with only half of its expected lifespan remaining.
   • The customer suspects the saw blade may not be the correct product, as the specifications do not match expectations.

2. Machine Operating Conditions:

   • There is a significant increase in noise, and the saw blade generates more vibrations during cutting.
   • The customer reports material damage due to the “buzzing” sound when the blade contacts the metal.
   • The cooling system is insufficient, causing the blade to overheat and not work properly.
   • During cutting, the blade experiences jerky movements, leading to uneven cuts and material wastage.

Saw Blade Usage Situation

Previous Saw Blade Usage:

• The previous saw blade (model 6555JJ) was used for a total of 41.67 hours and performed well. It was replaced due to decreased cutting efficiency, with its lifespan approximately halfway through.
• The current saw blade issues may be related to the equipment, as the customer states that the saw blade’s lifespan is also only half.

Proposed Solution

Actions Taken:

• Remove the existing damaged saw blade and inform the factory to carry out necessary equipment maintenance.
• Suggest the customer checks the machine’s alignment and cooling system to prevent similar issues in the future.

Summary and Conclusion

Cutting Condition:

• The saw blade’s cutting condition is normal; however, issues related to the equipment (such as misalignment or incorrect cutting parameters) are affecting the saw blade’s performance.
• The main problem appears to be related to the equipment, not the saw blade itself.
