This design philosophy makes the AT-770 ideal for factories requiring long-term continuous batch production, significantly reducing downtime losses caused by equipment failures.

Q8: How is the AT-770 trimming machine blade sharpened? How is the sharpening frequency determined?

A8:Sharpening the AT-770 blade is very simple, as follows:

1. Sharpening method: The blade is sharpened manually using a sharpening stone or dedicated sharpening device without removing the blade from the machine；

2. Sharpening frequency: The frequency depends on production volume, material hardness, and cutting thickness. Recommended guidelines:

   • Light duty (soft materials, small batches): Sharpen once a week；

   • Medium duty (medium-hard materials, normal batches): Sharpen every 2-3 days；

   • Heavy duty (very hard/thick materials, large batches): Sharpen once a day or check every shift；

3. Judgment standard: When trimming resistance significantly increases, or trimmed edges become rough with residual burrs, sharpening is required.
