Hey, Guys!
I have been grinding chains for a commercial sawyer for about 9 months. He drops off 30 chains at a time every 3 months or so. At first I struggled to get feedback from him regarding the performance of the chains (he cuts a mixture of wet and dry wood). Eventually I was able to get his take on things. According to him, his chains used to net him 1 1/2 to 2 loads (that's one pickup plus a trailer full) per chain. Currently, he is managing 5 - 6 loads per chain. That's around 3x as much cutting per chain!
Question: what, in your opinion, is causing the chains to last so much longer? The only variable I can see at the moment is the CBN wheels I am using on my chain grinder. I know most saw shops use the standard vitreous wheels. Could it be that the finer finish left by the CBN wheels makes for a longer-lasting cutting edge? It's much the same with knives - when the edge is stropped, it tends to last longer.
What are your thoughts?
Thanks.
Mike
