Buy the biggest machine space / economy / budget will allow. you will never wish for a smaller machine but i've lost count of all the people upsizing from a smaller purchase.

you could buy the ZAY...

When i brought my ZAY home i rented a hydraulic table lift rated for 800 lbs. i used round stock to shift the crated machine onto the table. lowered it down and rolled it into my shop.
The lift from...

i use Tcnc and have none of these issues [dwell marks or acceleration problems] i would be looking at back lash issues, and acceleration values for X and Y axis.

just my .02

Okay never mind.

I see it now. It sorta just POPed out of the picture ........... at first the white star laying on top threw me off. Now I see it is an example of the peice installed in the...

"Lovejoy" what a curious name for, what I am guessing is, a shaft coupling ..........

Can anyone show me a link to a site for these? I'd like to see one installed to get an idea of what it is I'm...

I am in the process of building a dual linear slide to lock the rotation of my round column lathemaster. I'll post up pictures when I finish it up.

Owen

Excellent. I'll have to wait till after work to get the info off of my machine.

I'll post it up then or if there is a formula used, can you post it up for me? I'd like to know how this is done for...

Can any one explain to me how I can calculate the power rating of my current servo motors?

The labe lists volts, watts, etc etc but no in/oz rating. All the motors I see listed on line show in/oz...

I'd recomend building a DOS box to run your cnc machine.
Windows runs in 'virtual time' and this can cause errors.
Dos runs in real time based on the CPU clock. Turbo CNC is an excellent program,...

Hi Phil

RPM is fully variable from 0 to the maximum of the motor. Full rated hp is produced at all rpm ranges as the VFD drives the motor at full volts at all times [there is no voltage drop like...

Hey Phil, yes theoretically it would. The VFD I'm using will go as high as 240hz but the maximum is programmable. So I'll set it to 60 hz or some value higher if I want to over drive the motor [once...

My VFD and 2hp 3phase arrived today.

Lafert makes an 80 frame 2hp 3400rpm motor that bolted right up. I'll post up the result of the install.

Weldon Shank endmill holders are built to match the shank diameter of the end mill. IE: 1/4" 3/8" 1/2" 5?8" 3/4" etc etc metric shanks as well. The end mill will have a shouldered flat spot ground on...

So I orderd a 2hp 3ph 3600rpm motor and VFD set up today. should be here next week.
More to learn ............. $700.oo canadian seemed reasonable enough. I wen't local v/s online expecting the...

Bill & Chris, thanks for an informative topic.

Bill: I replaced my ZAY motor in the first 3 month as the OEM unit died. Unfortuanately I didn't know of this forum and replaced it with the same RPM...

Does anyone know the over all height of the actual tool holder?

Owen

This looks interesting but can you expalin, as I can't make it out in the video, this tool holder has a straight shank and would be held in a chuck or collet? or is it an R8 shank.

thank you.
Owen

hanging weight and pullies is a very simple straight forward way of ballancing the weight of the head.
May not look as pimp but function over fashion I always say.
Owen

Are you direct driving the ball screw or is it pully reduced?
Are you moving the whole head or just the quill?
owen

Table sag from the weight all the way to the oposite side and loose gibs.
Gib keys that are not true lifting the table as they travel.
Table actually not ground flat and true [thicker at one end...

Try Borite bars.
Carbide cutters and boron bar.
and like Phil said above, more detailed data would help us help you.

Owen

What Dave says is very true.

I purchased my M/D for $1200,oo and to date have almost $4000.oo in CNC conversion. This includes: Ground ballscrews / nuts X 3, 3 servo motors, material to construct...

Hey Mike, can you explain a little bit for me? Isn't an R8 Taper a 'self releasing taper'? How will it get stuck?

Thanks.
Owen

Hi Dave, is this the model you are speaking of?

smithy CNC

Thanks Al.

The motor spins freely and feels fine. A technician took a quick look and said the motor tested fine but "encoder signals are out of phase. They are supposed to be 90 degrees out of...

i thought I should me more clear in that i don't need help 'physically' removing the drive. i want to know how to determine the proper size, voltage and such like that.
For example, this is a 22.5...

hey gang,

Seems I crashed my X axis last night :eek: and now my Servo motor is twitching erratically and won't respond.

The impact knocked the cover off of the encoder. Visually there appears...

Does the RF-45 offer more work area? i thought the table size and max height was very similar between the two machines [Pcnc / RF clones]

Owen

Thanks guys for the input. my current home built unit uses servos, i was just curious is all.

happy chip making.

Owen

Hi Willy, I know this is an old thread but, just in case you are still trying to get set up, I could offer this info.
I live in Western Canada, BC, and had Lathemaster ship thier h/d mill drill to a...
