The reasons for the collapse of the tooth cutting feed too much wire brush function is not suitable for cutting fluid too small sawtooth spacing is too small cutting release material when the sawtooth card and the material angle cut square, cylindrical material is about to end, sharp cutting load Increase the saw belt up and down jitter is too large Solution: adjust the feed to wear too much to be replaced, the improper adjustment of the position Increase the cutting fluid, the nozzle transferred to the appropriate position to change the pitch blade, or reduce the feed Especially with larger diameter solid materials. For smaller tooth band saws, reclining of inclined square material or reduction of feed.
