Hey,
first i already told ya the drives and motors are matched - they were dismounted from the same machine. Do your home work - NY41 version is a special series made purpousely for one company for...

Guys, any update or we need to scrap those DR2-08AC-NY41 drives? :(:(:(:(

Guys i need serious help.

I have a set of servopacks with matched ac motors. They are Yaskawa SGM series AC servomotors (SGM-08AFFJ12) with DR2 series servopacks (DR2-08AC-NY41).
Is it worth to...

:D:D

I wonder how did you drill-out so long hydraulic pipe accurately?

do you mean outer tube thickness is the same as thread thickness and inner element thickness in cross sectional view?

Thank you Andy for reply. Now i get the concepts behind the driven nut. I came to the same conclusion (4 squate pieces) when thinking about ATC grippers. Did you use Silver Steel for rod and other...

Great project and fantastic work! Would you share details of your steady screw-driven nut assembly? any dimensions for reference? I wonder how you made it so compact. What bearings did u use - a pair...

initially i thought mine encoders are 128 ppr but there are no 128ppr resolution listed under ROD426 encoders in Heidenhain catalogue...

Hi Folks,

I have two heidenhain incremental encoders. Theirs name plates say ROD 426.0010 - 128. Id. Nr. 250 048 57.
I found Heidenhain datasheet for the whole encoders family. ROD 426 is...

Thanks mactec54! 8-32 is enough to know to make one. If I manage to buy this mill (so far I can't even get info if that mill is still available... strange) i'll make that knob out of brass (knurled...

Thanks for info. Does anyone know what thread is that knob? I guess all the threaded connections on this mill is imperial, not metric. As i live in Poland we use metric system and i do not have...

Guys, i can't see micro feed reverse knob in the middleof the micro feed hand wheel... I saw cross sectional drawings of BP head and it looks little fragile to me.

SeebeaGizmo - i'll go for it. I'm not making money on metal cutting. It's just my hobby...
mactec54 - wow, that X power feed is HUUUUGE!

Regarding R8: how would you compare Morse#3 or even...

I found exploded view of 6F powerfeed for X axis:

Lot of parts as for such a simple task mechanism indeed:) What was the main issue? Worn brushes in motor, worn gears, clutches, electrical...

SeabeeGizmo - could you explain me what is wrong with x axis power feed mounted on that mill and X screw? I guess switch box is safer when mounted on the head - no coolant, no swarfs.and easy to...

Thank you guys for help.
Regarding Morse 3 tooling it will not be a problem at all as I live in Poland and most of my tools are Morse tappered. But I WILL have a problem with R8 taper tools. Import...

Hi guys!

I decided to go Bridgeport for a hobby use in my homeshop. I just love the way it looks like and read many good things about this mill. I found one that interests me much but I'm little...

I'll try solution with +5V fron USB - have you tried it? I assume GNDs must be connected together (USB&LPT) to avoid noises, spikes...

Hi everyone!
i've made three servodrivers of this type.
So far they work ok on the test bench:

wow, X2, RF45, mini lathe, bigger lathe... nice equipment:) what ya think about those little chinese lathes?

Do ya guys know some good source of timing pulleys for reasonable prices? here in...

i don't have one:) i have 3 solenoid valves, one for every axis and i plan to use reduced compressed air to push oil out of container. So it will be easy to set oil pressure with standard air...

i used flow control valves which consist of one-way valve and throttle valve in parallel connected. maxium pressure is 10bar. Althrough these are pneumatic valves i think they will work with oil as...

here is an oil malifold for one axis. 6mm OD / 4mm ID PE tubes for oil distribution. I plan to drive it with oil under pressure of 4bar. On top there are 3 regulation valves. Do ya think this...

i'm thinking about some deeper modification on Y axis. See pictures. What ya think? Y axis ball screw is to be lowered, say 20mm. It will give me opportunity to go out with ball screw at the back...

here is some my CAD drawings. Thank you Flenser for link. Now i recall i saw your thread before.
As for y axis double nut on screw: i'm worry that it will reduce Y travel. ??? Milling some flat...

Jermie, what ball screw size do you choose for x/y? I'm also converting ZX45. I think RM1605 screws are too tiny. But I don't know if there is enough room to mount RM2005 screws from RMB with two...

Hoe does antibacklash nut looks like? Is there some kind of backlash adjusment screw or what?

so what is better choice: ball screw with two nuts for backlash elimination from Rotton.com (5/8'' dia, .200'' lead) or screws with one nut per screw from mentioned earlier ebay seller from china?

Hi guys,

so advice me what is better: to order ballscrew assmeblies from china (ebay seller linearmotion2008) or from rotton.com (they have cheap 5/8 dia screws for ca. $10/ft and square nut for...
