Hello,
I am new to this forum and am hoping for some help.
I am running a small Grizzly G0602 lathe. When i first got it it gave a mirror finish using either HSS or Carbide. this was from 0 hours to about 5 hours on the lathe.
I decided to switch to a quick change tool post and the finish go a little rougher. I tried tightening things up but never liked what i saw with either HSS or Carbide so i switched it back to the original tool post.
Now the finish is garbage, lines or a smearing look on all pieces of metal. It seems to face ok but when cutting lengthwise it is pretty rough. I run things pretty close to the chuck and dial it in to about 5 ten thousands. I check the jib, the tool post, made sure it was square, tripled the check on the new four jaw, check gearing. I adjusted feeds and speeds on both HSS and carbide.( each time I have tried a new tool to be sure and for carbide i have used various types in my testing)
It sounds like it is grinding not cutting, lot of vibration. MY bits are centered and square.
Now on this machine i have to lift it to get access to the bottom nuts that hold the motor on so i can change from low to high speed. (i tried chaving a wrench but they are so tight i actually have to sling and lift the lathe to loosen the bottom nuts.
I put a dial indicator on the chuck and it runs true. Ran fast, slow, different speeds nothing seems to help. I recently checked for being level as the temp has changed drastically but that did not help either.
Can you guys give me any clue as to what i need to check next.
Thank you.
