I’m sure I’m not the first to ask this question, but I can’t seem to find an answer… I’ve been reading up alot on spindles for my journeyman, and I’m ready to buy one, but, I really only want to purchase once and not have to upgrade in the future to a better or larger one, I so I want to start with the biggest one I can get for my CNC, I would like it to be water cooled 220V, w/VFD the whole works, also do I need a larger hold down for this spindle? ---

Hey Carlos, > [@camswoodcraft](#): > > I really only want to purchase once and not have to upgrade in the future to a better or larger one, I so I want to start with the biggest one I can get for my CNC, I would like it to be water cooled 220V, w/VFD the whole works, also do I need a larger hold down for this spindle? if you mean the biggest by size, on the Onefinity CNC you can mount a 80 mm diameter spindle with the [optional 80 mm spindle mount](https://www.onefinitycnc.com/product-page/80mm-spindle-mount). If you mean the biggest power, this would mean 2.2 kW, as more powerful spindles usually have a larger diameter. If you mean biggest milling bits, you should buy a spindle with [ER20 collet](https://forum.onefinitycnc.com/t/how-do-you-ensure-your-model-translates-to-reality/13579/24) size since this will allow you to use milling bits with shank diameter of up to 13 mm (including 1/2″ shanks). If you mean a big sum of money, I would recommend [Mechatron ATC-8022-42-HSK25 2.2 kW 42,000 rpm water-cooled](https://www.spindel-shop.de/en/high-frequency-spindles--Professional-Series/automatic-tool-change-spindle-ATC-Series/Water-Cooled-HF-Spindles--HF-Spindle--HF-Spindles--HF-Spindle--HF-Spindles--Motorspindle--Milling-Spindle--Grinding-Spindle-4-53-54-79.html) ([unboxing video](https://www.youtube.com/watch?v=vB_FvkllLPc)) with [HSK-E 25](https://en.wikipedia.org/wiki/Machine_taper#HSK_taper) machine taper and [automatic tool change](https://en.wikipedia.org/wiki/Automatic_tool_changer) ([automatic tool change video](https://youtu.be/Pc_Tfk-vIyk?t=93)), a [cooling station](https://www.spindel-shop.de/en/Cooling/Cooling-Systems/) and a ready-to-use [electrical and pneumatic control cabinet](https://www.spindel-shop.de/en/Electrical-Cabinets-mechatron/) with [Omron MX2 2.2 kW VFD](https://industrial.omron.co.uk/en/products/3G3MX2-AB022-E) inside. If you want something simpler but still industry-grade, you could go with [HFS-8022-24-ER20 2.2 kW 24,000 rpm water-cooled](https://www.spindel-shop.de/en/High-Frequency-Spindle-standard-Series/High-Frequency-Spindle-HFS-series/Water-Cooled-HF-Spindles--HF-Spindle--HF-Spindles--HF-Spindle--HF-Spindles--Motorspindle--Milling-Spindle--Grinding-Spindle-4.html) ([datasheet](https://www.mechatron-gmbh.de/fileadmin/user_upload/Datenblatt_HFS-8022-24-ER20.pdf)), buy an empty [control cabinet](https://forum.onefinitycnc.com/t/what-i-learned-while-upgrading-to-2-2kw-water-cooled-spindle/13430/12) and [equip it yourself](https://forum.onefinitycnc.com/t/hey-is-this-your-vfd-enclosure/10130/3) with a [VFD](https://www.hitachi-ies.co.jp/english/products/inv/wj200/index.htm) and the [rest](https://forum.onefinitycnc.com/t/hey-is-this-your-vfd-enclosure/10130/3). At least two persons in this forum own this spindle. Note that it is recommendable to always buy the spindle cable from spindle manufacturer. Note that some people [replace their z axis assembly](https://forum.onefinitycnc.com/t/universal-z-axis-assembly/4415) (see also [here](https://forum.onefinitycnc.com/t/has-anyone-replaced-their-z-axis-assembly-for-greater-travel/9028/) and [here](https://forum.onefinitycnc.com/t/any-hobbyist-grade-solutions-for-adding-automatic-tool-changes-to-onefinity/8476/7)) which would allow for even larger spindles.

Thank you, so after looking at your response, it seems I’ll stick with the 220v 2.2 kw 80mm spindle, I will buy the whole kit, it comes with a bigger mount, but I might purchase OneFinity’s mount they sell. Thank you again ---

I bought the 1F 80mm spindle mount when I ordered my Journeyman. Swapping it from the 65mm took about 10 minutes. I bought the Huanyang 220v kit with VFD (Amazon $390). My kit did come with a 220v water pump, so I bought another 110v pump for about $20. I also bought the Breakout box, from !F, so my Controller controls the spindle start/stop and speed. So when I set the speed for the bit, inside the toolpath in vCarve, I know the correct speed is set for that bit and can also see and verify on the VFD. The spindle uses the Er20 collets, and I bought a couple of spare collets (through AVID) so I have an 1/8", 1/4" and 1/2" for easy bit changes. ---
