Hello! I would like to sharing of the MM build.
I started with Z axis.
Congratulation Gerald, for sharing this great project.

[Jayson]

Welcome Vladimir,

My Z axis doesn't look anything like that :eek:


I look forward to seeing the rest of your build.

Jayson.

[jvfc]

yes, I make a little modification on Z axis :)

Great progress guys! Looking good!

[Kobus_Joubert]

Good going there...I like the picture in post#4...on the pants the words FATAL....the person welding with bare feet....now THAT is maybe not fatal, but could be painful sometimes...:D

Are you sure you have enough space for the machine next to the house....when you have 2 x X-axis steppers hanging on there will it fit ?

Hi, My foot have a carapace that protect it.:)
The space is just enough for the MM.

Vladimir,

I like your Mill opereator. She looks like a good worker. She needs a stool so she can easily work on the Mill.

I thought I didn't have much space. Can you move around on each side with the motors on?

Little lathe; little operator :)
The place is just for make test, betimes move to another place.

[Kobus_Joubert]

That is a funny looking spindle....to me it looks like a normal electrical motor with a collet? What make is that and how much did it cost ?

[hennie]

Did the Little lathe operator made your wheels ?

[javeria]

Vladimir, your pictures are a lot of help - especially the detailed washer assy pics, G' we need to have a construction gallery with subtopics covering the pictures of individual assemblies.

no no I don't volunteer to do it :)

[Valdir Fernandes da Cruz]

Hi all, yes, this is a normal electrical motor, the price was $ 115
Valdir

[Gerald D]

Are you going to run it at normal speed, or are you going to push its speed up with a Variable Frequency Drive?

[jvfc]

Are you going to run it at normal speed, or are you going to push its speed up with a Variable Frequency Drive?

Yes, Variable Frequency Driver....0~300hz- Max speed about 16900 rpm.
the cost here, about 210.00 USD

hugs.

[Gerald D]

That is very interesting! Have you guys tried this before? What about the bearings? Can the rotor survive the centrifugal force? (Podemos sobreviver o rotor da força centrífuga?)

[Kobus_Joubert]

I will also following this NEW Spindle closely...did you have to modify it to take the collet or did it come like that ?

[Gerald D]

Kobus, a "spindle" is no more than a standard 3-phase motor with better bearings and a smaller diameter (longer length) rotor to stop it from flying apart at high speed.

[jvfc]

That is very interesting! Have you guys tried this before? What about the bearings? Can the rotor survive the centrifugal force? (Podemos sobreviver o rotor da força centrífuga?)

Yes, I use it on my first router machine about two years, sometimes change the bearings by better quality.
it is a Siemens standard 3-phase motor 1HP 3420 rpm.

[javeria]

Vladimir - can you post the g code file (for Mach) for the above - or share the dxf file plz, my kid would love that insect.

RGDS
Irfan

[jvfc]

ok...the file

[javeria]

Vladimir thank U

[Kobus_Joubert]

Thanks for the info Vladimir...looks like you are an old hand at this CNC thing.
Two more things..
1..did you put thread on the motor shaft ? or how did you fix your chuck ?
2.. How many millimeters / inches is that motor in diameter ?

Looked at your movie...what a sweet sound.

the mechmate is the third project .I've learned always.
the motor shaft has a M5 hole, Put a screw inwards of chuck.
the diameter this motor is about 135mm.

thanks

Hello! I would like to sharing of the MM build.
I started with Z axis.
Congratulation Gerald, for sharing this great project.

Hi Vladimir,
Can you give a plan for the Z axis ? Or a list with material you used to build the Z axis ?

Thank you,
Marius

[jvfc]

first test.

The Mechmate write: thanks Gerald.

[Gerald D]

Nice video, thanks :D

Well done Valdir and Vladimir (and daughter)!

Can you please us more about the control box?

[jvfc]

Nice video, thanks :D

First cut. 2mm end mill

[Gerald D]

I wish I could have been there to see it!

Congratulations!

Your video shows a fairly small cutter mounted on a standard AC motor and it cuts at quite a good speed . . . . . . very interesting. . . . .

[Gerald D]

Can you show us photos of the cutting quality you get on the edge of the MDF with a 6mm cutter when you cut about a 100mm diameter circle? People say those big motors are not good, but the end of your last video shows a very fast and controllable machine. The only question now is the cut quality.

How does it compare to this (http://www.mechmate.com/forums/showthread.php?p=109&postcount=1), where we had direct drive with a smaller motor?

Hello Gerald, I make a test of the circle and square. both 100mm with 6mm cutter and 2500mm/min.
the measures show me accuracy.

hugs

[Gerald D]

Thanks for the pictures. Is that maybe about the same as what we saw at 80 mm/second (4800 mm/minute) with the shorter motors? I know it is very difficult to compare by photographs alone.

[jhiggins7]

Vladimir,

Congratulations on your build. Gerald as added your build to the Builder's Log.
The updated Builder's Log is here (http://spreadsheets.google.com/pub?key=pLoxg8wu4WnsBc2_U5yEaQw).

Please tell me how big your table is. For example what are the dimensions of the spoil board I see on your table?

Also, when did you actually start the build? Your first post was on 10-Jan-2009. But I think you had already been working on your MechMate before 10-Jan-2009.

Finally, you will notice that your entry is not bold and that you do not have a serial number. I think that you almost qualify for a Serial Number. I think you only need to add MechMate Logo's to qualify. Of course, Gerald is the one who makes the decision to award a Serial Number, but I wanted let you know how close you are to earning a Serial Number. I'm currently building a MechMate and when I get it completed, I will be anxious to earn a Serial Number.

Regards,
John

[jvfc]

Hello, I would like much a serial number.
we started the build 04-may-2008.
table measures standard 2750x1883.
soon the MM logo's may be fixed

Best wishes

[jhiggins7]

Thanks for the update Vladimir.

The updated Builder's Log is here (http://spreadsheets.google.com/pub?key=pLoxg8wu4WnsBc2_U5yEaQw).

I hope you earn your Serial Number.:)

Regards,
John

[jvfc]

hello, today we make drilling on table, to fix nut with claws. video below

[domino11]

Wow that machine looks really good. The videos are very impressive. I think all you need now is some decals and the serial number should be in the bag! :)

[Valdir Fernandes da Cruz]

We needle to install the cable chain and to fix the Mechmate logo.
Where i can to find the standard Mechmate logo?
Thank you
Valdir

Hello Folks, two works .

http://www.youtube.com/watch?v=4Y8NUK_tbi8

[javeria]

Vladimir - I am amused at the way you hold the parts - with something as big as a Mechmate its quite difficult.

nice work though :)

[J.R. Hatcher]

Vladmir I sometimes use the same principal, except I use small sticks 18" or so long. I have cut the ends off by mistake several times. If you continue this hold-down method you will too. All I needed to do was cut more sticks. What will you need to do ???????????????????? :(

Nice cutting machine :)

[javeria]

I will answer that -replace finger tips :D

[jvfc]

Thanks!
I don't like a long stick, but it is necessary :). very danger machine.

[J.R. Hatcher]

I don't like shortened fingers :D

[gixi]

Hi Vladimir,
I'm curios how Linear Guideway takes the forces when you cut material like wood for example? Does those guideways resist in time and for how long ?
Because when you cut along X and Y axis there are a lot of force in order to push through material.

Thank you,
Marius

[jvfc]

Marius, you question is about linear guide that I use in my Z axis?
My linear guide of the 20mm:
charge= dynamic capacity is 14.1 KN
charge =static capacity is 24 KN

[jvfc]

hi all.
I would like to sharing this incredible work done by machine called mechmate .
logo mark of our workshop, this will be internal environment.
hugs

[Doug_Ford]

Outstanding graphic design. Very professional.

[domino11]

Looks Great! :)

[Gerald D]

Good to hear from you guys again! Looks great!

[jvfc]

thanks guys, more news soon.:)

[Lex]

Hi Vladimir,
How is your motor and z-slide holding up? Are you still happy with the cut performance?

[jvfc]

The cut is not as good, but for major work is acceptable.
soon we will use 3:1 reduction.
hugs

[jvfc]

[PEU]

cara vc ta maluco mesmo! (you are crazy dude!) :)

The MM bridge can wipe you out of the table in a split second if it makes a bad move, be carefull, no jokes, be carefull you never know when something goes wrong, shit happens...

When I use my cnc mill I always use protective glasses, yeah, friends sometimes give me that look, but I only have a pair of eyes and I plan to keep them as they are right now... :)

Be safe!

[Gerald D]

Thanks Vladimir! What coolant/lubricant are you using?

(Pablo, let's not start a safety debate here)

[jvfc]

PEU, the mechmate machine is very reliable. :)

Gerald D, I use Soluble oil, 4 flute, 6mm HSS end mill . 10.000 rpm 0,4mm depth and 1300mm/min feed rate.
the drilling was used a 3mm solid bit and 5mm deep

hugs

[PEU]

(Pablo, let's not start a safety debate here)
oops sorry... :)

[kmac_20]

hi there great job

[jvfc]

Thanks!
I used our mechmate to drilling the steel "I" profile, it will be used in my current cnc project.
http://www.youtube.com/watch?v=TYDn7xW3l9A

here My Z axis, it has been cutting in mechmate

regards

[sailfl]

Vladimir,

That is one large plate. What are you going to attach to it?

[jvfc]

on "I" profile, I will fix linear guides for the X axis of my next CNC project.

[jvfc]

I milling some 1/4 steel plate on mechmate, 26mm hole, I use it for my new CNC router project

[cncb]

wow one stout plate!! is that 3/4"? Must be a heavy z slide.

[jvfc]

Yes, Z plate are 3/4" .It is Very heavy.

best regards.
Vladimir

[jvfc]

mechmate originate a monster! :)

[jvfc]

We feed the hungry dinosaur. see the cheerful face of the victim. :)

Another mechmate job too.

[liaoh75]

Cool T-Rex. May I ask about the material (MDF I assume?) thickness? And where you got the DXF for cut file? I'd love to cut one myself for my school. Thanks

[domino11]

Nicely done Vladimir! :)

[jvfc]

Thanks... i use 9mm MDF for T-REX an 3mm for human
for T -rex just increase for 9mm MDF

Regards
Vladimir

[Kobus_Joubert]

Thanks for sharing Vladimir. What size is the human and the T-Rex.

[buibui]

Great...one Christmas present taken care of. Thank you Vladimir.

[jvfc]

Thanks for sharing Vladimir. What size is the human and the T-Rex.

T-Rex is 1,2m height and 2,1m long
Human is about 350 to 400mm

[Valdecir Domingos]

Olá Valdir e Vladimir estou fazendo estudos para começar a montar uma "MechMats" a de voces ficou otima parabens;
Eu sou leigo no que dis respeito eletronica os drives que usarão na maquina voces mesmos construiram ou foi comprado e de quem? os motores qual o torque e a Amperagem?
Desculpe as perguntas mas se puderem me ajudar fico grato.

[jvfc]

Another big creature.

[javeria]

Vladimir - what are you trying to do - set up a new Jurassic park! :D

[jvfc]

Hi javeria, I change the theme and make this handsome man :)

[liaoh75]

Vladimir, that's one cool T-rex. Thanks for sharing!!

[javeria]

ha ha ha : :D

[Gerald D]

Nice! :D

How did you make the black/white program? (software?)

[jvfc]

Nice! :D

How did you make the black/white program? (software?)

I used an image editor (PS) to turn the photo in black and white and increased the contrast in maximum and then trace with COREL.

Vladimir

[jvfc]

another version of this handsome man :)

[jvfc]

a very dangerous place for dogs

[jessyjames]

They have been found at my house too. What is going on here.. Looks like mine might be a different breed... :)

[jvfc]

Very cool your raptor, only the tail is contrary :)

[MariusL]

Vladimir,
In a previous post you said that you increased the dino to 9mm. What is the process that you follow and what software do you use?

[pln]

Hi vladimir which stepper motors you use on your cnc?

[MariusL]

That tail must just be inserted the other way around.
