Do you chrome the pieces yourself, or send them out? If you send them out, do they charge you by the batch, or by the part?

We send them out to St. Louis Plating, they do batch and part pricing depending on the number of parts.  They do good work and are fair on pricing.

Final Summary

Final Summary

The mill has been running strong and I am gaining confidence in it each day.  Its been making sample parts and so it time for a video.

I also wanted summarize some stats on the mill before and after the conversion to Mach3:

1)   Position Accuracy: Before 0.0003, After 0.0002
2)   Max IPM: Before 300, After 350
3)   Power Consumption: Before 220VAC 3 Phase 50A, After 220VAC 1 Phase 40A
4)   Spindle: Before 7.5HP 100% Duty Cycle 6000RPM, After 7.5HP 100% Duty Cycle 6000RPM

Pros of the Conversion: 1) Easy to fix and repair, 2) Tool Probe, 3) 4th and 5th Axis ready, 4) Support via Mach3 Forum, 5) ….

Hi,

This is my first reply to you thread but found it very interesting to read.

You must be very proud of the work you've done on this machine, I would if I were you.

Maybe some more video of you future work on your ''new'' CNC.

Congratulation and again, great work and keep posting.

Nice build, I think you like working on Miilling machines more than choppers now.   Amazing attention to detail you've done.
 I retrofitted an older Bridgeport mill using the Viper200 drives running its SEM motors and they work well.
 What did you do with the old bridgeport motors ?  Were they still good ?

I still have the old motors and plan to put them into the bargain basement with geckos and power supplies as a system.  I did try the vipers and they worked good, but the AC Servos work great, very fast excelleration and power.

Your right, these old machines are like restoring an old car or truck, fun stuff

Joel,
Congrats on a superb effort and end result!
 
I read thru each of these pages intently as I have two similar machines.
They are a bit newer, Kryle's, similar size, same type tool changer, but linear ways, 16 tools, and Fanuc 0M with red cap AC motors.
My plan is to retro them as you have done with yours. The parameters have been messed up and/or lost in the 0M controls, and no luck
getting them back in correctly.....just as well, I hate Fanuc controls.

One question I have for you, could you use a servo on the tool carousel and treat it as an axis in Mach?
My machines have a small Fanuc servo to operate the carousel.

Also, the spindle orient situation:
You were getting within a few degrees with the AC motor alone.
How about a tapered "shot pin" arrangement operated with a small air cylinder that would pull the spindle into perfect position?

Just some thoughts as I will face the same challenges with my project(s)

Thanks

I hate to jump back a few pages, but Im trying to mimic the tool probe setup.  I am not very experienced with screen designer..... I have the buttons setup as buttons, I just dont understand how to mpa each button to the function and how to get the DROs setup and mapped, if someone who has done this can post some screen shots and how to do it with screens 4  I would sooo much appreciate it!

Im new to doing the screens thing so treat me as if I was a 4th grader please LOLOL
