2* Alignment Critical?

1st Thing.... Disclaimer:
This has nothing to do with ScottR..
In fact, Thanks Scott... You get a Trader+

The Spindle Mount has a 2* mis-alignment.
It's not the set-up, it is the Mounting Bracket Spindle Bore.
Even if I turn/index the Spindle body, the error is still there.
Would you run it like this?
What's the tolorance for vertical alignment?

2 degree?, 2 thou? Either one is a little much IMO.......you should be able mount the bracket at dead nuts zero. It'll just take a little patience and some shim stock.

How are you measuring your mis-alignment?

2 Degrees

Hi Dave,
Thanks for replying..
It's 2 degrees, I used a protractor.

The Spindle Mount is part of the Spindle Combo.
I drilled/tapped the Mount holes true to the Mounting Plate that mounts on the Z axis Tower.
There's a little "Play" in the screw holes in the Mount.
I got it to about 1/2 Degree.
I guess it just looks funny, seeing the mount crooked.

The motor is really quiet...Quieter than a Pencel Sharpener.
I think I can run the CNC at night. (Windows closed).
Big difference from the Makita 1100 Router.
I'm going to try the .009" cutter today..

Motor Quiet, With spindle, noisy..mmmm

Thanks Chris, Just a little more filing should do it..
Dave, It was a Starrett Machinist Protractor.
Not the drawing kind.. I should have stated it.. Sorry..

.009" cutter works.. Engraved a Hercek logo..Fonts a litle more cleaner/clearer..
Spindle Body comes hot.. I brush on water for coolant, so, I bush water on the Spindle Body.
Cools it and the water drips right on the cutting area.

Do what you have to do to get rid of the 2 degree misalignment. Redrill the bracket holes a little oversized so you can rotate it a little. If you have misalignment from front to back just use shims to take care of that. Either way you should be able to get it dead on with a little adjustment.

Alton...Use a dial indicator to "dial" it in. Use your protractor for drawing!

There are a couple different ways you can set it up to check it but no matter what size cutters you use, you want it as close as possible in line to zero. Check it on one side and then go 90 degrees and check it on the other. As per Chris mentioned...open the holes up for movement in one direction and you'll have the shim between the the plate and the mount for other direction.

Alton, it looks like the bracket need to be mounted better, fenders washers don't work in my book. you need to tram it in, with a small dial indicator. I suggest you get a good tool and die maker over for an hour or two to help you. my guy spent most of the day doing it , luckly he likes beer, i paid him that way. darrin

Fender Washers?? Yes..

Hi Darrin,
Got those counter sunk holes behind those "Fender Washers"..:grin:
The store was closed today..
Going to get the right bolts tomorrow.
I know it loks like a "Frankinstein" Machine..
Those other stuff are accessory brackets.
Thanks for posting everybody..
It's runnin' O.K.
Could use a lot more speed.

Alton your the man, I'm a big fan of your work. machine set up is so important , getting it tramed in can make or break your machine. the bit must run straight , with low r.p.m is the key , than speed it up.

Alton,
I hate to hear that the unit is giving you these challenges. Let me know if you want to do something on the deal. Thanks.

Alton you may be able to move the lower bracket where the spindle is mounted. Then readjust the mounting plate to the machine. I am not sure if the mount for the spindle is pinned or if there is some adjustment. This will help with your last 1/2 degree.

You did good!!!

Alton,

Scott

Not a problem Scott. The guys here all willing to help.
Thanks for your offer for a deal on something, but,
I think you gave a good deal on the Spindle combo.. I know you took a lost..
I thought everything was precisionly fitted on CNC's.
Mine has the Band-Aid* repair/modification tricks..:sorry:
Scott, this was the biggest improvment to my CNC.

Thanks for posting John and Darrin..
The cutter I use was a .0079", according to the specs.
This is the 1st test run of a Joel Hercek Cap..on a .875" diameter Delrin.
They are double line fonts..
The depth if the engraved lines are .030".
I got a machine plate and a sine vise and variable speed controller
on the way from e-bay.. all good deals. So good, the shipping cost as much as the products..
All should help improve my machining processes..
Thanks again for viewing..
Alton
New Information:
Richard (Wolfgang Engineering) told me that they discovered that their CNC Z Axis was sightly off when they made that production run on the Mounts..
That accounts for the misalignment..
