There is no universal replacement interval. A blade cutting clean, softwood logs may last considerably longer than one processing abrasive hardwood, frozen logs, or logs containing dirt and bark.For commercial sawmills, it is usually more economical to rotate several blades and sharpen them regularly rather than simply replacing a blade every time it becomes dull. A properly maintained blade can often be sharpened and reused multiple times.
A sawmill blade should generally be changed or resharpened when cutting performance starts to decline, rather than after a fixed number of hours. For many band sawmills, a blade may cut effectively for several hours of continuous sawing before it needs sharpening, but actual blade life depends heavily on wood species, log condition, blade quality, feed speed, and maintenance.
1.How often should I change my sawmill blade?Generally, a blade should be sharpened every 2 to 4 hours of continuous cutting. Depending on the wood density (softwood vs. hardwood), a blade can typically be sharpened 4 to 6 times before it needs to be replaced.
