My online supplier for band saw blades gave me the following information that affects the life of a band saw blade.
This may mostly apply to metal cutting but this should be relevant in using a band saw used in wood working.
There are 3 tool destroyers: Heat, Shock and Abrasion. Tool wear failure always results from one or more of these causes.
There are 22 variables that influence a band saw blade life.
1. The Operators – The operator knows the machine best.
2. The number of teeth in the band – should have 3 minimum, 6-12 optimum, 24 maximum
3. Tooth style – Choose the tooth style that best meets your cutting requirements
4. Tooth set – Regular, Wavy, Every Tooth Set, or Modified Raker
5. Band Tension – Proper tension should be applied
6. Band Speed – Start with the manufacturer’s recommendation
7. Break-In procedure – Reduce normal feed rate by 1/2 for every new blade
8. Feed Rate – Set rate by square inches per minute suggested by manufacturer
9. Band Quality – Carbon vs Bimetal or Carbide Tipped, one brand vs. another
10. Machine Type – Different makes and models, hp of motor
11. Wheels – Check alignment, bearings, flanges
12. Machine condition – Old, new, well-maintained
13. Proper Vises – To hold the work firmly
14. Guides – Should support the band, roller guides should barely turn by hand
15. Guide Arms – Should be as close to the work as possible for support
16. Brushes – Aid in the cleaning of chips from the gullet of the band
17. Coolant – Should wash, cool and lubricate
18. Material Machinability – The toughness of a metal can reduce tool life
19. Material Hardness – A Rc of 40 has a machinability approaching 0
20. Material Shape – Structurals and small solids tend to be harder on the band
21. Production requirement – Continuous vs intermittent use
22. Room temperature – Affects hydraulic fluids in the machine.
I hope this helps!
