Stair Beam Machine !!! #120 - Jõgeva Estonia
 

I started construction last year. In this time i haven't camera to make photos but some pictures i found. Today is almost ready, i have to make last painting and srew it together.

I upload soon the latast pictures.

Table size is 5,4x1,6 meters

I would say welcome, but I can see you have been with us a while !!!

Cool skate mod ... !!!

Yes this original skate, whit height adjustment bolts dosen't work. Because result of grinding is not smoot.

Now is metalwork is done. I have to make controlbox and conect motors and spindle.

Nice!!!

Interesting hybrid Z slide.... can't really tell from the pic, if that is running on V guides or what ?

No whit linear bearing. For some reason i dont trust this original z axis.

Would you care to post some larger pics on the Z ? I am trying to figure out what to do myself ( I am also doing my Z with bought linears), and curious to learn more from all kinds of different solutions I have seen on the MM to come up with my best solution.

I can upload pictuers and detali drawings in weekend becaus i'm now in finland.

Sure, no worries.

Ivo :( why black and red

I must say I regret every second of painting my machine black and red as it always looks dusty even if not used for routing a day.
Complete white, gray, Blue or yellow in that order are my preferable colors from now on :)

I think, it's not problem. Because this machine is desinged for working and it's not decoration.
Ofcorse evryone has their opinion.

But thanks for warning!

Little progress, mine watercooled spindle is no arrived jet. But machine is alive. And i have to finish mine vacuum table .

Vacuum pump: 2.2kw

List of work that needs to be done:

Limit switches
Computer console finishing and mounting
Change cable carrier(To small cable chain)
Start, pause, stop Pushbuttons
4 th axis
And some little things

I like your control cabinet.

Very nice

I see you Modified the gantry raising it up a bit for clearance. Nice long table. Nice neat control box with 5 drivers. Your steppers look big !

Looks great ... I hope you will soon be making money with it !!!

Yes steppers are to big. In future i planed to change other 3 steppers also 878 oz. Right now are there 1600 oz x and y axis. Z axis have 878 oz stepper.

First cuts are maded half year ago. It maded so long for stair beams, whitch are main jobs for this macine.

Everything is preparated for 4 th axis. I made electicbox for 5 drivers. Just have to install lathe chuck and wiring.

Only problem is vibration now. But those 1600 oz stepers needs to run higher speeds. In low feed rate they vibrating. Or ther some other problem?

I suspect the motor vibration comes from the motor driver. High torque stepper motor do have this resonance short fall.
878 oz stepper motors are still too big, I use 640 oz direct drive without lost step for years.
Not that I oppose going way oversize, but just tot you might feel comfortable knowing.

Ivo... so machine is designed with long table to cut stair beams.
.... we call them stair stringers here in the USA

Thanks fo correcting... mine english is not bestest.
I use stair drawing's software and there it called Beams.

At the moment, about 10 stair detalis are cutted whit this machine.
Much easier then make it by hand and powertools. And also time and precision factor.

Other English speaking countries may call them something other than stringers.

Sometimes called stair horses ... especially if there is a beam between the outer beams (stringers) but I think the outside beams can be called horses also

I did not know there were softwares for cutting them on a router
