Re: [CAD_CAM_EDM_DRO] Re: Using a Grizzly Super X3 as a lathe

I have to agree he did do a nice video, but if I new I was going to make a whole pile of these adapters, if a jobs worth doing...........,da da da, I feel sure that time is not that important unless he's on production and yes it does the job, but my feelings are if I was going to show the world my bits and pieces I would do my best, to me its like going to a good movie that has been well produced but spoiled by some of its content, copper touch on, did you notice the machine ridges in the bore, also if the touch pin is not square,................ I think I would make a block bored to fit two precision bearings and clamped to the table with a post in the bearing bore for attaching a dial indicator,.................... main body not finish machined (wobbly),....... no chamfer (sharp corner), ...........these are things people notice, (again if its just in the shop ok) but now its in cyber space with budding young wannabe machinists and hobbiest
 out there, .......the drilling was ok but followed up with a reamer, that's gambling (you might get lucky) but it should have been single tool bored to fit, or at least I would almost bore to size and then ream 
 
I'm sure he is aware about of all this, I cut corners myself, but then I have no intent of filming my stuff,
 
All in all it was a very good video very well done,

Hi,

I too thought the videos excellent. A couple of constructive suggestions come to mind.

1) Run the file over the end at the end of the first cut; just to break that edge also while it was in "spinnable" position.

2) When the work was in second stage; turned over NOT in chuck) trim a bit from the 1.5" body portion; just to remove the wobble and true it all up.

3) For the drilling of the toolholder hole; using the drills to get the hole opened up a bit is ok; but there is no way the drill chuck held on mill bed will ever be acceptably true to the spindle and bed for my liking. The super long reamer will amplify this runout. Better to do the final cuts to make the hole with a boring bar; do lotsa super super small boring bar passes and back out the boring bar and try to fit the desired end mill till done.

Regards,
Norman

Hi,

Great videos!
I had been wondering about getting the Tormach tool set. Your videos show that it need not be too expensive after all!
I noticed that the accuracy of the centering is completely dependent on the accuracy of your copper pipe that you use with Mach 3 - if that is off centre, i.e. the shaft and circumference of the tube are not 100% aligned then the tool holder that is made will 'wobble' - how concentric have you found the holder to be?

Many thanks for doing these videos.

Phil.

This two-part video covers the making of Tormach TTS-style toolholders using my CNCFusion-converted Grizzly SuperX3 Mill/Drill as a lathe (mounting a lathe tool in the milling vise, mounting the work in a 3-jaw chuck in the spindle, and running the work past the tool to do simple lathe operations).

I don't harden them, and I don't bother cutting the relief on the face of the holder that contacts the spindle. I never use that feature - the main purpose of the holders for me is convenience in switching out tools (assisted by my homebrew pneumatic drawbar) - but I'm sure if needed, others could figure out how to run a few facing cuts to replicate the true TTS holders.
