The weight of the 2.2kW spindle without the VFD (variable frequency drive or inverter) is 11 lbs or 5 kg.

The 2.2kW spindle with the VFD is 15 lbs or 6.8 kg.

I am interested in buying the water cooled 2.2 KW spindle for $339, how much does it weigh?

We don't have experience running a spindle directly from a rotary phase converter, unfortunately. The fear that I have is the control of the voltage and current to the spindle and how that relates to the coil winding for each phase. If your rotary phase converter can operate within these tolerances (which need to be known), then I don't see the problem, but the spindle will exhaust its warranty by doing this.

Regarding the CAM software, speed can be set for various machining operations, but the actual speed control will be controlled by the control program that interprets the g-code output by the CAM.

I am looking at purchasing your 2.2 kw water cooled spindle. I'm assuming it comes with the VFD. I have a rotary phase converter in my shop. Are these spindles 3 phase? And if so, can I bypass use of the VFD and control the spindle speed by the CAM software instead? Or is the VFD an absolute necessity to use on the spindle?

Yes, our 2.2kW water cooled spindles can accept the 1/2" collet size.

Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. It requires making some changes to the settings in Mach3 and in your inverter. It also requires an additional part, which is called a USB to Serial Converter, found on our site here:

I have some additional instructions, that I will send upon request, by email. I will also be adding a complete tutorial and video, to the website, on how to do this soon.

Can you control the spped of the 2.2 KW spindle using the breakout board and Mach3 soft ware?

If you are using a silicone tube with a 1/4” ID, it will fit the nipple of the 1.5kW spindle water connections measuring an OD of 0.31”. The silicone will stretch and you will need to use water or saliva to help the tube fit.

The tube ID being smaller than the nipple will help the seal prevent water from leaking.

There is no specific manner in connecting the water lines to the spindle. No specific output and input locations, only the diameter which we use is 1/4 Inside Diameter and 3/8 Outside Diameter (you might find another one that works just as well).
Unscrew the 2 hose nuts and feed the tube through (will be snug), and adjust the tube on the hose fittings and screw the hose nuts down. Feed the tubes through your machine towards the water bucket, making sure it will not get caught on any moving parts and cause a jam/leak, and fit one tube to the outlet of your water pump and leave the other tube to the bucket as a return line. (unless you are using a cooler like a radiator, then feed it to the outlet of the radiator and to your water pump)

You can use a compressor to unclogg the water lines of the spindle. We use this method and it works every time (so far).

We have manuals for the VFD rather than the spindles. Can you specify what issue you may be having so we can help you better?

Additional Information:
I am having trouble wiring the VFD. (From the wall outlet to the VFD) I think the manual or setup guide on your website is wrong. The two diagrams show two different sets of terminals on the page.

Also, do you have a video or other documentation on programming the VFD? Your videos and documentation looks like it only covers the 1.2kw version. Are the two different spindles from different manufacturers?

You can determine you overall CNC machine current consumption be adding your spindle power plus your CNC motion power and the power that your computer requires.

the formula to understand the current of each component is watts = volts x current, or W = V * I, or with some algebra, Current (I) = Watts (W) / Volts (V)

For example:

Spindle:
The 2.2 kW = 2200 watts and you can find the current by taking the input voltage of 220 volt and get the current using the above formula: 2200 W / 220 V = 10 A (Amps)

CNC motion electronics:
The power supply that comes with our machines is generally 8.8 A

Computer:
The computer that you use to control the CNC machine will have a specific wattage. Let's say the watts is 500: 500 W / 110 V = 4.5 A

Add them up: 10 A + 8.8 A + 4.5 A = 23.3 Amps

Hi, I'm considering buying one of your 2.2 KW water cooled spindles. What is these spindles run out ?

Welcome to this wonderful world of fabrication. Our 2.2kW water cooled spindles measure 80 mm in diameter which is 3.14 inches. This is the standard for most spindles of this power. You may need to get a mount made for this diameter.

Yes, all of the spindles come with collets. The collets have a 1/4" (6.35mm) bore for end mills that have a 1/4" shank. The ER specification is different for the 1.5kW (ER-11) and the 2.2kW (ER-20).

The AVID CNC has a control box that contains a large connector with a lot of pins. Two of those pins are reserved for the on and off of a spindle. Hook up pins 7 and 8 of the Avid CNC control box to FWD and GND in the VFD and control the speed with the dial on the VFD.

[77] Hello. I’m interested in buying a water cooled spindle and VFD. I have an Avid Pro CNC and would love to control it using Mach 4 but I keep hearing it’s difficult to integrate. Also, is the water pump 120 or 240? I’d love any advice etc. eBay is a web of confusion with all of the options. Thank you.

From reading on the Hitachi WJ200-022SF VFD, it seems as it will work just fine with this VFD. However since we have not tried this cross match, I would carefully take each connection and setting into great consideration and detail on both the Hitachi recommendations for setup, as well as our spindles recommended setup.
Our spindles do not have a thermal couple temperature output.

Will your 2.5 KW spindle work with my Hitachi WJ200-022SF VFD and does it have a thermal couple temp output?

Our spindle should work fine with your Delta VFD-M 220v. Spindles that match a VFD are specific to the coil windings. The bearings, shaft and other mechanical components that make up the spindle may be different, but that should not matter.

I have a GMT 2.2kw water cooled spindle that sounds like the bearings are going out and want to know if your spindle (https://buildyourcnc.com/Item/spindle-inverter-2!2kw-spindle-novfd) is comparable for a swap. The drive is a Delta VFD-M 220v.

Our spindle VFD's, have a multitude of different connectors that can be used for different operations. There is a manual that comes with each VFD, and you can refer to page 11 for different functions and descriptions.

We currently have a PWM, working with our machine, however it is connected via USB, and setup through Mach 3.
Also if you may have misplaced or lost the manual here is a link to the pdf:
