i have 2 of the 2kw watercooled model and both after 1 months of use have bearings problems. did replace with the new japanese bearings now i am facing the motor can just suddenly underpower and stop...

Hi angelababy what makes you sick of 2.2kw chinese spindle? I've got problems with them one of them is that when I'm cutting sometimes it just stop dead but the vfd keeps on going. I've look at the...

Thanks for the info Gerry!
I'm not sure if my machine can handle 30kg motor, I'm using hiwin 25mm linear guide and 25mm ballscrew what do you think?

how do you mount this HSD ES919 30Kg spindle motor?
113498

Thank you Al.
This next question is off the topic: which is better HSD or FIMEC? or are they about the same?

How come I don't have respond from HSD usa and also try HSD italy and also no response from them. btw the HSD ES919 - H6161H0289A 7.5kw model with f63 short nose can I use ER40 with that? or am I...

So it doesn't matter wether it is 2 or 4 poles? on the 4 poles model speed is 12kRPM/24kRPM 400Hz/800Hz and the optimum torque is at 12kRPM above that the torque drops (I prefer the optimum torque...

got it Thank you Al
oh btw is 4 poles motor better than a 2 poles motor (given all the specs are the same except the number of poles)?

I am planning to get a 10HP 7.5Kw 24000RPM either 2 or 4 poles spindle motor from either colombo, fimec, or hsd to run @24000RPM I need 800Hz capable vfd. just wondering if the SJ series from Hitachi...

do HITACHI VFD run up to 800 Hz?

anybody got experience with 7.5kw HSD or FIMEC spindle motor? are they good?

thank you guys, but how about FIMEC? anyone knows the quality?
oh and HSK F63 have short nose and long nose which one is better?
and also do I need an AC LINE REACTOR between spindle motor and...

How is the HSK better than the ISO? is it more stronger, precision?? I don't believe they cost twice as much though.
Is the tool setter expensive? and how do you measure the way you do? just make a...

I wish I can go to Poland and see master Bartuss at work! :):):)
But the those hollow steel isn't perfectly straight and have the same thickness do you need to grind it down to make it perfectly...

yes I am aware of the price but I want to get the best, I am really sick and tired of the chinese 2.2kw spindle motor (I think it's a junk). I have 3phase in my place so no problem with that.
Btw...

is PDS colombo the as Giordano colombo?
where can I get RS 110 ISO30 - 2 10HP 7.5Kw 380V 200/400HZ 12000/24000RPM 17.5A 2Poles?

now what if the the table isn't perfectly square and level??? how do you build your table that is totally flat and square? because for all I know that none square pipes are totally straight and event...

it turns by hand freely when the motor is not moving (off)

very nice machines Bartuss1! I love the 5 axis one. btw how do you level and line up all those linear guides and ballscrews???

the spindle runs cool but even without load the spindle speed is not constant

my spindle is 2.2kw watercooled guys

My apology to put this here because seems no one is looking under tooling section.
which one is better: ISO30 or HSK F63?
FIMEC or PDS COLOMBO?

PDS COLOMBO:
RS 110 ISO30 - 2 10HP 7.5Kw 380V ...

anyone knows which is better FIMEC or PDS COLOMBO spindle motor?
and ISO30 or HSK F63?

the spec of the spindle 2.2kw water cool is: 2.2Kw 220V 8A 400Hz number of pole(I don't know). I check the resistance of the spindle motor U to V = 1.7 ohm U to W= 1.7ohm V to W = 1.7 ohm U,V,W to...

nope, the endmill is brand new. I am not sure which one is faulty could it be the hitachi? or the spindle?

I have a new problem with my 2.2kw water cool Chai's spindle the torque drops drastically when I'm cutting 5mm deep teakwood using 10mm flat endmills. What seems to be the cause? I'm using a new...

please help,
I want to be able to jog at 700IPM at 3 meter length probably going to use rack n pinion system and prefferable a servo motor. can you guys tell me the spec for servo motor and also the...

pease help,
I would like to know what kind of servo motor do I need to achieve 700IPM and what rack n pinion size do I need at 3 meter length? and also gearing etc

thank you in advance guys.

how much is it to replace it with servo motor (what is the spec for servo)? and what gearing do you use on the rack n pinion? I'm really interested on building one someday

Mark and Bartus why don't you guys use servo motor instead of stepper? are they better for the job? but servo is more precision.
