G0704 - 2.2kw water cooled spindle motor & belt drive upgrade - making chips.

[@CodySSC]

Dada... Dada. Dada! Can I have a muffin? DADA! Lol sounds like my shop. Great job on the conversation, I'm looking to get mine changed over right now

[@adaptedmachining6951]

He definitely got the muffin. 🤣🤣🤣

[@brentsrx7]

Your setup is amazing. Well done sir.

[@peterchiverton7981]

Nice work mate it seems to work well, I am doing this set up at the moment, I would like to know your VFD settings as I am having trouble making my spindle get up to speed. cheers peter

[@Shopbuilt]

Nice setup, I'd be curious how the power is at lower speeds for say drilling a 1/2" hole in steel. I use a 1hp ac motor on my mill and it really struggled at the low end, I have since upgraded to a 1 1/2 hp and it is alot better but could still use a little more. How do you find the heat in your spindle bearings? The best I can really get is 6500rpm for any opt that is more than 15min long. I actually installed a temp prob on the bearing to keep am eye on it. The nema 34 on the x and y is on my list of upgrades is like to do to:)

[@adaptedmachining6951]

I don't really do any steel on this machine. I know it will struggle with the belt setup it currently has.

[@Telectronics]

I also want to do the same like you but I have a GT2 belt setup 3 to 1 can I use that ?

[@adaptedmachining6951]

Figure out what the belt is rated for and go from there.

[@Telectronics]

You mean my belt should be rated at least motor torque times 3 because of the torque increase right ?

[@connorbabcock8197]

Just subscribed. Great machine. After 3 years, do you still like your motor choice? Im considering doing the same

[@adaptedmachining6951]

It worked well for the machine and the aluminum parts I would use it for.

[@advil000]

I can't tell just by looking at it, is that the steel or aluminum fixture plate? Are you still ok with the weight?

[@advil000]

I should read more. Your old video pic says steel on the thumbnail. Wow. So, are you still ok with the weight?

[@adaptedmachining6951]

@@advil000 The weight has not been an issue so far. Although I did upgrade to 906oz/in nema 34 motors for the x & y. I wanted to be able to have really good rapid speeds and acceleration to be able to utilize the high speed spindle. I have a video of making a head spacer coming up later today.

[@bookyle21]

Could you have used the spindle directly? Would that have been too low torque at 8k rpm?

[@adaptedmachining6951]

The spindle on the mill is more durable and able to withstand much more than the bearings on the motor. Also yes, torque would be too low. The 3:1 reduction multiplies the torque.

[@KyrychenkoAnton]

Hi, great work, can it cut steel?

[@adaptedmachining6951]

I've done some 1018 steel with a 1/4 4 flute endmill and it was no problem.

[@DR-br5gb]

Smart upgrade. Which belt are you using ?

[@niksechtniks]

hey! can you slow the spindle down by hand on lowest power setting's ?? tbh i find this the Ideal budget uption for a cnc motor replament! cheap way of getting load's more rpm on youre origional spindle thumb's up!

[@adaptedmachining6951]

You can slow it down by hand on the lowest settings, but torque drastically ramps up by raising 500 rpm from minimum. I can drill with a 3/8 drill bit on the lowest speed without issue.

[@niksechtniks]

@@adaptedmachining6951 Okay thanks! i will try this out to. would you mind sharing the motor pulley size's if you remember ?

[@thechipwelder1253]

Great video. I am planning to do something similair on my 6040 router if I buy a belt driven ATC spindle. Do you think that there would be any issues mounting the water cooled spindle (motor) upside down?

[@adaptedmachining6951]

I would check with the motor manufacturer. The only thing I can think of is the potential for an air pocket not allowing the motor to cool properly.

[@thechipwelder1253]

@@adaptedmachining6951 Thank you for your reply. I strongly doubt that I would get a good answer on that from the manufacturer. Might be so that I would have to take one for the team and try it out myself. :D Will test drive the watercooling upside down with no power connected. If it is good circulation and no leak inside the spindle then I think I am good to go. I find most of your videos very intresting, so you got yourself a new subscriber. Cheers

[@yz400fer69]

Did you locate a spindle motor with a solid shaft or did you modify the ER collect to accept a pulley? I have thought about doing this to a PM25 but can't seem to locate one with just a shaft to press or put a pulley on.

[@adaptedmachining6951]

[@adaptedmachining6951]

Its a custom pulley in an er collet.

[@yz400fer69]

@@adaptedmachining6951cool! Anu issues with slippage? I found your other video that mentioned the lapping compound - curious how that setup is working out.

[@adaptedmachining6951]

@@yz400fer69 I've never had any issues with slippage. The compound works great. Especially on stepper motor couplers.

[@2259chevy]

What size shielded cable did u use ??

[@adaptedmachining6951]

16 - could have done 18

[@brendinemslie8226]

I've really enjoyed all of your videos? Did you upgrade the bearings on your G0704 spindle to support 8000 rpm? What is the RPM range you get now? Can you still use the quil?

[@adaptedmachining6951]

Spindle bearings are upgraded to angular contact and rated to 10k. Quill is deleted as it is useless for cnc configuration. I removed everything related to the quill from the head.

[@MrFreeway99]

would you be willing to share the mount file?

[@adaptedmachining6951]

I'm not sure that my mount would be compatible with anything other than my custom rails and motor bracket. I'm actually working out a design for a smaller billet mount that has it's own clamp for the motor. I would be more comfortable releasing that design when i have available.
