I have disassembled and partially disassembled my mm 7x16 lathe at least 3 times. First two times was to make it operable. The first time was to basically clean it up. Why ? Because it would not move well at all and would stick and well, not useable.? Next time was to refine things, both cleaning, filing, better adjusting as i under stood more. Partial disassembly was to further get things refined. I did much of this before I got info off of youtube or here on this site. And it continues but getting better as I go. But yea, one really gets to know the machine and the adjustments and such. Now if something is not right I can pretty well figure out what is going wonky. But the biggest learning curve came from basically two issues occuring at near the same time. One was cutting with chattering and cutting off which was shall I say, interesting. Now, i know about making sure the cutters are adjusted properly to the center of whatever is being worked on. I did this but now realize that even though i adjusted it before on my qctp, it does not remain centered if it comes off and then reinserted. Also found that it's critical when parting off. Now i have no issues when i recheck centering and adjust it before doing any cutting.? Specially on the cutting off blade. Has certainly changed my results big time. Dont assume, check ! george

You find most accuracy problems is with operator.? I helps if lathe is right but good operator can over come this problem.? It like DRO on cross slide it is only aid to new person all do is look at marks not number.? The flex in just everything comes in play and you have adjust.? Dave? Paul Fox 8:16am? ? People here and on other forums often talk about having had to clean, fix, shim, adjust, tweak a new lathe in order to make it accurate and useable. And that being willing to do so lets you start with a less expensive mill, from HF or Vevor, say, rather than one from LMS or Grizzly |
