I have a cold saw i bought, couldnt afford a brobo etc at the time so i bought a cheaper version, still cost over 2k at the time but other options where 2x that.
It has never cut properly, it seems to chatter and then it would stall. I decided to change the single phase out for a 3ph motor and the is no stopping it now but it chatters like crazy. I cant afford to keep stuffing blades so im looking for ideas. I have stripped the saw down and checked it out. The worm drive and all the bearing seem ok. There was a little back lash in the keyways on the brass worm gear so i have fitted new keys. But i cant see it being enough to be causing the issues.
I ran out of time to get it back together to re test but i am wondering about the way this saw clamps. Instead of a fixed back clamp jaw and a moving front clamp it has both jaws moving in towards a centre point.
Could this be causing the blade to not be in good cutting angle? For example cutting RHS it really struggled to cut through the top flat, takes ages. Then it breaks through and starts to chatter badly on the side walls, and it seems as though it is trying to drag the box out of clamps.
Any thoughts or suggestions on what the correct cut angle should be?
Thanks
