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.

We actually tried dissassembling one of our spindles in house with no success, but I just found a good thread on CNCZone that has a good set of photos and instructions.

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

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

WHAT ARE THE OUTPUT INVERTER (VFD) CONNECTIONS TO SPINDLE?

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.

1.5KW water hose 1/4" ID - 3/8" OD does not fit in spindle fitting with ID 0.31"

The 2.2kW spindle has a power rating of 2.2kW or 2200 watts.

If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work.

If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work.

It is never too early to begin planning for the coming fall's influenza vaccination program. The most important thing you can do initially is to place your order for vaccine from your usual source. Some manufacturers often stop taking pre-orders in mid-May. Be sure to include vaccine for pediatric patients needing two doses and also for your facility's healthcare workers as part of your overall campaign.
