Re: seperating workpiece cyno
¿ªÔÆÌåÓý
Too right! I had a gallon (1.25 US gallons) can of acetone, nearly full. It?lurked?untouched in the garage for 30 years. When I eventually needed some, it was empty. The top surface?had gone rusty (condensation, probably) and there were one or two pinholes through it. ? Andy To: 7x12minilathe@... From: maschwiebert@...

Yes and me too. I was?taught many years ago at
college and confirmed later by a manufacturer, that all axis relate to the
workholder. Consider the lathe, the spindle axis holds the work. Now a vertical
milling machine, the spindle holds the cutting tool, but so does a horizontal
milling machine and the spindle is parallel to the bed!? Never mind slant
bed machines, multi-axis machining centres etc. So the Z axis move towards
and/or away from the workholder. The X & Y axis move across the workholder
at right angles to each other. Not all 3 need to be used eg centre lathe and
some machines have 4 or more axis eg multi-spindle machining centres. However,
as we are not all professional machining companies, we don't need to get our
knickers in a twist over it.
Cheers.

HF 7-10 conversion
Hey guys I have an 2002 HF 7 by 10 that I was thinking of getting the LMS 14 in. bed and doing all the mods you can do with it, BUT giveing all the costs that will come up with it, would I be better off leaveing it as is and getting a 9 by 16 I want to be able to do finer work then old bettsie does altho its not bad ,the limits kinds put well a limit on you and now that I have lots of time (hope I do) I want more room to play thanks ED

Now you are really confusing me. In message 69578 you said the on a lathe the Z axis was the long axis parallel to the lathe bed and also the spindle axis. Now you tell me that the spindle axis determine the x axis. Which is correct. Mike --- In 7x12minilathe@..., "Dick" wrote:

It is not the work holding arrangement but the "main spindle axis" which determines the x axis. Dick --- In 7x12minilathe@..., "Ellis Cory" wrote:

No, you are correct for a milling machine. The
problem comes with so many layouts of modern CNC maching centres. That is why
the workholding arrangement was chosen as the point of reference.

Re: Real Bull 7x14 lathe questions?
Bob,
I've had a Real Bull 7x14 with gear box since May, and I love it. It did come with quite an accessory package, including a 4" 3-jaw chuck, (which is standard if you buy it from Big Dog), steady and follower rests, metal main transmission gears (not all of them), tails stock drill chuck, live center and dead center. I really liked the accessories (though I have not yet used the follower rest) and I especially liked the 4" chuck and metal gears. Just my two cents...

Assuming I'm the Charlie you're referring to (a little presumptuous on my part since you made such nice comments!), I'm still here. I spent virtually the entire month of January traveling on business, including my weekends, and wasn't even able to get downstairs to my shop until this week. Hopefully that won't happen again. As a result, I've been reading the digest emails but not posting. Thanks for thinking of me; everything is OK and I should be participating more now that the January travel craziness is over!

Well it seems that all this time I've had it wrong.? Fortunately, I've never discussed this with anyone so it's my secret.? How it came to pass I'm not sure but my X Y&Z has always been to me that X is left right, Y is front to back (milling machine) and Z is vertical.? It seemed to make sense to me so I've adapted this.? Not being a math genius or a CAD operator or working with anyone else equipment? or drawings I don't see any problem.? I have seen the "follow the thumb" rule but that has always been associated with electricity.? Tell me if I should change my thinking. Warren |
