Chinese Spindles

[JAZZCNC]

What size machine is this going on.?

I have thought for a long time that the BT30 spindle Cartridge that tormach sell as an accessory could easily be made into good ATC.? Again not overly cheap but doo-able.!! Though needs a large strong machine.!

I'm going to enquire with a company I deal with who make,repair, high quality spindles. The stupidly expensive multi KW spindles with ceramic bearings alone costing 1000's but I did wounce mention could they make a cheap ATC cartridge and they said possibly and draw something up and they'd have a look.? . . Never did maybe when I have more time i'll look into it more.?

6'x3' steel frame, as an alternative i could use a chinese spindle geared down 2:1 or similar to drive a spindle cartridge.........

Yourself and others have been helping me decide on its design for a couple of years now lol

I wouldn't because the price of a 3HP 3 phase motor is so much cheaper and give far more torque done to very low RPM. You could gear it up if you need high RPM.
There are loads of 3PH motors in scrap yards and not silly money new.
To be honest I very rarely need over 10-12K but often would like the abilty to go lower than 5K which the WC 2.2KW just can't do and still be usable.!! Honestly these spindles don't have high torque even with a torque vector drive.!

its more a size thing for me the chinese motors themselves are quite compact but if there are alternatives then i would be happy to look at them...

Ye thats why I asked about size because unless large or designed for at the outset then could be hard to impliment or so limiting it's not worth the trouble.

Ok well maybe im going down the wrong track, maybe i should have just asked if there was a suitable spindle that suited an atc conversion was not massive in size had a speed of > 6000 rpm but would be happy at 1000 rpm should the need arrise (lower speed not essential because not against using pulleys) but had a good amount of torque

Well not so much a wrong track has a potentialy expensive one with high percentage for disapointment unless well thought out.??

Like I say if it was relatively easy and CHEAP they would be available by now has there have been plenty of people asking about ATC over the years since affordable WC spindles arrived on the scene.!!

I'm sure it will happen sooner or later thou.??????????????

Use your own motor to suit,
