Silly issue with HBM parting blade
| Andy Carlson | 24/07/2020 18:14:47 |
| 440 forum posts 132 photos | An update... it works a lot better when the blade is the right way up 22mm to 1 inch of EN1A. Setup was very careful, using a square (again) to check the blade was vertical and perpendicular. Ran into some chatter about half way through. Tried increasing speed from 253 to 456 RPM but that made it unbearable. Went back to 253 and stuffed the tool in harder... chatter gone. It came out very well, no obvious sign of doming when inspecting the finished cut but for some reason the blade looked like it was veering off to the right during the cut - must have been an optical illusion brought on by numerous prior failures I guess.
