The sights and sounds of failure

摘要

Making bandsawing jobs more productive and efficient is as easy as get-ting to know how the cutoff operation should look and sound. Tell-tale signs such as tooth damage, crooked cuts, or unusual noises can indicate impending problems, thus giving shops the opportunity to correct them before sawing production comes to a standstill. For starters, shops should visually check bandsaw-blade teeth for heavy wear or chips welded to the tips. Stripped, chipped, or damaged teeth after a cut often indicate improper feed and speed settings or inadequate coolant. A low, insufficient feedrate causes premature dulling and vibration which further damages cutting edges.
