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

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.

• What is the runout on the 2.5 KW spindle and how many bearings?

The runout on our 2.2kW spindle and number of bearings are:
Radial runout: 0.01mm - 0.000393701 inches, 3 Bearings

What is the runout on the 2.5 KW spindle and how many bearings?

• 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 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.

• Are there instructions to disassemble the 2.2KW spindle (220v)? We need to replace the bearings.

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.

Please let me know if this helps.

Also, If you have no success, let us know and we will make an attempt here on video.

• [77] I have a 110 volt 2.2kw water cooled spindle. Can I run it with a 220 volt VFD?

I have not tried connecting a 110V spindle to a 220V VFD; however, the parameters in a 220V VFD do allow changes to the values for the spindle motor. If you do plan on connecting the 110V spindle to a 220V VFD, damages can occur, so I would not recommend it.

With that said, here is the output of an LLM:
Using a 220-volt VFD (Variable Frequency Drive) to run a 110-volt spindle is technically possible, but it requires careful setup to avoid damaging the spindle. Here's what you need to consider:

Check the VFD Specifications: Ensure that the VFD can be set up to output the correct voltage for your spindle. Many VFDs are capable of outputting variable voltages and can be configured via their programming settings to match the voltage requirements of the spindle.

Adjust the Output Voltage: You'll need to configure the VFD to output 110 volts to match your spindle. This is crucial because supplying 220 volts to a 110-volt spindle would likely damage it permanently. Check the VFD's manual for instructions on how to adjust the output voltage settings.

Set the Current Correctly: Besides voltage, make sure the output current does not exceed what your spindle can handle. The VFD should be configured to supply the current at the rating appropriate for the spindle’s power and voltage requirements.

Consult the Manuals: Always refer to the manuals of both the spindle and the VFD. These documents can provide specific guidance on compatibility and settings.

Consider Professional Installation: If you are not familiar with electrical systems or if the manuals do not provide clear guidance, it may be wise to hire a professional. This helps ensure that the setup is done safely and correctly.

By taking these steps, you can safely use a 220-volt VFD with your 110-volt spindle, ensuring it operates efficiently without risk of damage. Just be meticulous with the settings and when in doubt, consult with or hire a professional.

• I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

• It seems that the water cooling lines inside my 2.2KW spindle are clogged. Is there a way to unclogg them?

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

• What is the Greenbull average power consumption in conjunction with 2.2KW spindle?

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

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

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:

https://www.buildyourcnc.com/item/Interfaces-newbiehack-Interfaces-TTL232R-USB-UART-Serial

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.

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

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.

• [78] What size circuit breaker should I use for this spindle?

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.

• WE ARE ALWAYS CONCERNED THAT THERE WON'T BE ENOUGH VACCINE TO VACCINATE OUR PATIENTS IN THE FALL. WHAT CAN DO ASSURED WE'VE DONE ALL POSSIBLY AVOID THIS TYPE OF SITUATION?

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.
