Bandsaw blades

Even though two bandsaw blades may be made by the same company, they are not always the same quality.
I started to cut out some new blanks and changed the bandsaw blade before starting. The old blade had cut 23 1/8" CPMD2 blanks that were 8 1/2" OAL. and 7 1/8" CPM S35VN blades that were 8 1/2" OAL. The new blade started off fine but before I finished cutting the first D2 blank, I could tell a difference in the cutting speed. I cut a total of 2 1/8" CPMD2 blanks 8 1/2" OAL and two 3/16" CPMS35VN 11" OAL but was not able to finish cutting the last 35VN with the new blade. I had to switch and put the old blade back on to complete the last one. The blade that was new was bought from a supplier that I had never bought from before and will not again. They were supposed to both be Lennox blades.
 
First thing I thought when reading was that you didnt allow the new blade to get "broke in" And was treating it like the old blade right out of the box. Blades need to be babied for the first couple of cuts, or should I say fist couple of blades you cut out.. (dont ask me how I know this)

I have done the same thing you just described. with 2 blades from the same box. and after talking with other makers and my supplier. It seems to be the problem I had. And I have done it more then once. lol and every time with the same results.

This may not be the case with your situation, Just trying to help.

Stay Sharp!

God Bless.
 
Randy, could you explain how you "baby" a band saw blade? Do you just cut ultra slow?
 
Don,

You slow things down from what is used on a blade that's already "broken-in".

Two ways to do it:
1. Decrease the blade speed.
2. Decrease the feed rate.

I like to feed about half as fast for the first 5-10 minutes worth of cutting on a new (saw) blade.
After taking it slow to break in the new blade, things can be sped back up to normal.

Yep, What he said!! :) Thats exactly how I do it. (when I remember, which is sometimes after trashing a new blade)
