| Stripping
or cracking of teeth Use proper pitch and speed. Eliminate vibration by holding the work-piece firmly. Check for running backwards. Band breakage or break at the weld Place guides as close as possible. Side guides too tight. Adjust band tension. Gauge of band too heavy for diameter of wheels. Reduce feed. Premature dulling of teeth Use slower speed. Keep teeth engaged. Adjust feed pressure. Consult cutting chart for right blade selection. Blade not cutting straight Use lighter feed. Set guides as close as possible. Adjust guides for even wear. Increase band tension. Use coarser pitch. Burr on back or grooves in side of blade Adjust the two back edge rollers so that both share the pressure equally. Adjust side guides. Check coolant. Check alignment. Saw blade vibrating in cut Consult cutting chart for right blade selection. Hold work firmly. Increase band tension. Adjust feed pressure. Increase speed. Gullets loading Adjust speed to properties of material. Use coarser pitch. Rough surface-finish Use finer pitch blade. Use higher speed. Reduce feed pressure. Cutting rate too slow Use coarser pitch. Increase feed pressure. Use higher speed. Premature loss of set Saw blades too wide for radius being cut. Use slower speed. Adjust guides. Twisted blade Reduce feed pressure. Side guides adjusted too tight. Use proper blade for radius being cut. Band binding in cut. Band stalls in work Reduce feed pressure. Check blade tension. Reduce speed. Band squeals while cutting Increase feed pressure. Reduce speed. Check pitch. Chips welded to teeth Check chips brush. Reduce feed pressure. Check cutting fluid. Excessive speed. Band humps while running Check the weld area. Check backup bearings. Check machine. Saw blade not penetrating Check material hardness. Reduce speed. Coarser pitch. |
