Show"N"Tell ( What you have made with your CNC machine.) / Re: KNIFE SHARPENER

Just some pic's of a my belt grinder after restoring an old UBG-622 Hammond belt grinder.
Will use it for sharpening, scale removal, and deburring

SPECS:
- Belt Size adjustable:  1" to 2" wide x 42" to 60" long ( may add another idler to allow use of 72" belts)
- Dust collector system
- 3 Belt speeds: 1465, 2835, 5652 SFPM
- Motor: 1 1/2 HP  (reversable via switch  to allow belt travel in both directions)
- Contact wheel: 6" x 2"  ( a few others are being made 8"x2", 2"/ 3" / whatever will work )
- Weight: 250 # approx
- Footprint required: 24" x 24"

The platen was made perpendicular  to the column and belt. Scab platen added for easy surface
renewal. Additional adjustment added to belt back plate. Narrow and wide backplates.

Still need to make another platen assembly for the contact wheel. Additionaly a nice work light,
magnifier, fold down tool / work table, and additional grinding guides to be done.

For now it works great, maintains tracking very nicely, all adjustments are easy  and quick.

1. With the spindle / router not running, when you jog, do you get vibration? One axis at a time for now!
    if yes,
1A. Is the vibration constant when jogging, ie; jog the full travel length, and when jogging does it change when at say the start, 1/4 of travel,1/2 of travel?
2A. Do the same as in 1A, but at three rates of velocity, say low, medium, high , and max velocity. Is the vibration constant or changing?

Reply the best you can to the above,

BTW, Can you post a pic of the machine since the Industrial CNC Site didn't show one.

PC, controller,MPG's , etc all mounted on a compact movable cart works well for me.

You may want to have a look at AutoEditNC for re-numbering of lines and it's free.

Show"N"Tell ( Your Machines) / Re: Made a new center setting gauge for the lathe today

« on: July 23, 2014, 08:04:31 AM »

I wonder if an edge finder would work.

I use an edge finder and it works great and is very accurate. I use the displayed DRO values to record the offsets.
Like Hood a height gage is used for setting tool height, and after the tool table is populated, I also refine the threading tool
offset.

The "trick" is to use Mach for measuring the offsets using a reference line (ie; the od and face of the edge finder), use mpg's to touch off to the edge finder, and use a different screen set to avoid the back and forth between screens. Also
the master tool concept is used.

Some where i have a write up of exactly how it's done.

LazyCam (Beta) / Re: No fully shows the g code

Use whatever is confortable for you and gets your work done.
Every user has their owne preferences and different software provides different features.
You'll just have to research / compare them and in the end the decision is yours.

You manualy program Gcode for what you want to machine or use a program that generates the code .
Programming Handbook by Smid covers most everything you need to know and will be a valuable resource
for learning and use in the future.

You need to purchase a license for LazyCam if you are using any of the advanced features such as offsetting.
I would suggest you have a look at the Lazycam manual for additional information. Lazycam is no longer being developed and frankly you may want to have a look at other software such as Cambam.

« on: July 15, 2014, 07:45:58 PM »

Jeff,
Don't remember but would think for a rotary it would be in degrees ( if it is not configured as linear ). Easy enough to test just try 360 and see what happens.

But what is the best way to set the backlash within the Mach3 program

You set the backlash for the axis under the tab CONFIG>BACKLASH.
Find the amount of backlash and then set the backlash using the 50-50-50 rule for starters .
