Jeff,
There are internal clearances in the BP Knee Mill that must be observed. For example, the yoke at times runs close to the Z-Axis jack screw. Therefore, material from the Y-Axis ballnut must...
The bearing block is not flat on the backside. So it is impossible to make an impression of the bearing faces, and therefore make good measurements.
So the best to be done is to make hand...
Ok, there is a little maintenance for me to do on the y-axis anyway.
So, I'll pull it apart, make an impression of the bearing block and develop a CAD drawing. I can't do it today, however. My day...
I checked the drawing again and you are correct. The center is above the midpoint, at least 0.135"
But, the only way to know for sure is to take the bearing holder off, trace it onto paper, scan it,...
You've got the same numbers I came up with.
I chose the midpoint, both horizontal and vertical. With the hand crank on I drove the ball screw clockwise/counterclockwise a number of times to let...
kenztasos, I'm unsure what you're asking. Are you seeking drawings, equipment specifications?
A couple of years ago when I changed to the servos, I decided to build a little test routine, a test routine to simulate peck drilling. So I fired up Mach and sent the machine out to simulate peck...
A few years ago I built a MechMate router for a specific purpose. The machine has a cutting envelope of 72x144x8. This machine also has a very heavy gantry, well over 100lbs. I got tired of the poor...
Follow the link below and read all the information carefully. Ray did a good job documenting his Quill conversion and has posted his documentation here. If you need more information on the BP quill...
I've been down this road before...
Is it possible to use the original steppers? Yes. Is it practical to use the original steppers? Perhaps not.
To pair the old steppers up with newer generation...
I had a similar problem in the beginning...
The Hicon Integra board needs two power supplies to operate. It needs a 24VDC power supply, as well as a 5VDC power supply. Without a proper power supply...
I know this is late, sorry...
Yes, I have the HiCON Integra - 6-Axis Step/Direction Ethernet Motion Controller (pn 7766). I've been running it for about two years without any problem. Hook it up...
Jim,
Great job with the Z-axis conversion.
I converted my Bridgeport 12x42 Z-axis both ways. Once with the ballscrew in front, and another time driven from the left side of the machine as you,...
Stuff That Gets Broken
Going through the old Bridgeport is interesting. My 1965, Series 1 had problems when I bought it. Today, I'd like to discuss four of the problems I found with the machine...
I got around to replacing the Driven Spline Shaft on the machine yesterday. I became so tired of hearing the old shaft rattle and feeling the vibration coming through the head. See the photos at post...
Yes, thanks, all the servo drivers I'm looking at come complete with matching servos drives. Don't want to mislead here, the torque mentioned earlier was Peak Torque @ 6,000. Continuous torque is...
Just a short post this morning.
Description of photos are:
1) Before disassembling the machine, the drive assembly sounded overall quiet and generally smooth. The bearings were a little rough...
Thanks Mactec for the info. Yep, I see the same thing you say about the servos. One has to decide the direction one wants to travel. I've got my eye on a 463 oz-in @6,000 rpm, 2kw servo. We'll see...
mactec- did you servo the spindle motor, or leave it an induction, single phase, three phase. and did you move from the R8 spindle?
reason is, i am moving from the 1hp-3phase to possibly a servo,...
Kenny- Sorry to come so late to your thread.
The problem with the Clearpath servos documentation is, Teknic does a poor job relating their encoders to others on the market. The equipment is good...
BMSTECH-- I want one of these light thingys' when I grow up.
Great work on the Z-axis!!
I like all the work you've put into the machine. I never heard of KING RICH, but she really has nice...
Mactec54 - I apologize for the brash tone yesterday. A brash tone in verbal conversation between two guys, is sometimes the way we guys get our point across. But, in the forum it is more difficult or...
X and Y axis photos attached
all three handles remain
Posted are three photos of the Bridgeport Z-Axis as it sits today.
I machined all the fixtures you see here using my CNC router. The gantry type router I built is quite large, the bed envelope is...
Mactec54--The subject of this thread is, Build Thread, Bridgeport Series 1 Retrofit.
This thread is about the retrofit of a Series 1 Bridgeport. Because this retrofit is technically complete,...

I do not understand your claim that I "payed way too much for them (my servos) with such a low Resolution Encoder". Perhaps, the Teknic literature was not clear with their description of...
It's easy to get all wrapped up in the theory of counts per revolution. I certainly was guilty of that when I ordered the servos for my router. I purchased the standard model thinking, 800 counts is...
I've learned a lot from many people here at CNCZone. First off I want to say, "Thanks" to the many that take the time to share their experiences.
Over the last few years I've read much regarding...
Sorry to join in on this old thread. I know it's been a year from the previous post, but I hope my comments are still relevant.
You can complete the retrofit under $4000 since you have the ball...
