Question #: 14628

Question: What brand is the 2.2 kW spindle? Same for the VFD. Thanks.

Current Solution

Spindles are generally covered up to 1 year after date of purchase. We do not repair them in house, but we do work with our manufacturer to replace defective units. Generally if you have a defective unit covered under warranty, we will issue a replacement.

  • What is the recommended unit or brand of CPU cooling system for the 2.2 kw spindle on the Fabricator Pro machine

    There really isn't any specific brand. We purchase the components in a disparate fashion from China. I will product a video today that shows all of the components that we use and also offer the components on the website.

    From the upcoming video, you will be able to identify the parts is you feel you want to search for these components yourself.

  • What is the minimum RPM for the 2.2kW spindle?

    Spindles with 2 poles, which is typically for these types of spindles will have a minimum RPM of 6000 RPM or 100Hz; however, I would not run the spindle below 15000 RPM or 250Hz to give a safety factor and no damage will occur.

    If you have a 4 pole spindle, then much lower RPMs can be achieved, and with higher torque than a 2 pole spindle. The 4 pole spindle will require more power than 2 pole spindles and will not be able to achieve as high maximum RPMs.

  • please send wiring diagram for the 1500kw spindle and inverter combo. i need to see what additional things need be purchased. thanks.

    Please refer to the Spindle wiring diagram found on the product page for the 2.2KW spindle. The wiring diagram will be the same for the 1.5kW Spindle. The only difference will depend on if you are using 110v or 220v power, as setting PD008 asks you to specify the max voltage.

  • What is the rpm range of the 2.2kw spindle and inverter?

    The VFD is capable of a maximum of 400 Hz frequency. That converts to 24,000 RPM for the spindle. The minimum frequency is 100 Hz which is 6000 RPM.

  • What are the noise levels of the 1.5 Kw and 2.2Kw spindles?

    The noise level of the 1.5 kW and the 2.2 kW are very similar. The noise level is considerably quieter than typical routers. I am going to add sound db levels to this FAQ a bit later.

    Additional Information:
    The db (decibels) reading for the spindle is 70 and an 890 Porter Cable router (a lower powered tool than the spindle) measured 90 db. Both measurements were taken in the same environment and measured at the same distance from the tool.

    Additional Information:
    Practically silent. The inverter makes more noise!

  • What size breaker is required for the 2.2kw 220v vfd ?

    Since a 220V 2.2kW, or 2200W spindle will consume 9 to 10 amps at full torque:

    2200W/220V = 10A
    2200W/240V = 9.2A

    then a 15 amp breaker would be suitable for this load.

  • Are there any other manuals for the VFD that comes with the 2.2kw spindle?

    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?

  • What is a normal max operating temperature for a 2.2kw water cooled spindle?

    I don't know the exact temperature, but the spindle actually needs to get to a relatively high temperature for normal operation and to protect the bearings. IF I find better information from our supplier, I will add this information to this answer.

  • on the 2.2Kw water cooled spindle, what is the cooling port thread type and size?

    It is an M8 metric size on the port going into the spindle, and a 1/4" compression on the other side.

    Is the M8 port a M8x1.25 or M8x1?

    If you are referring to the book build, use a chamfer bit that is large enough to create a chamfer for most of the edge of the 3/4" thickness of the board, but still has a sliver of space for the bearing on which to ride.

    Additional Information:
    Mine is M8x1mm. I replaced the stock fitting with a brass hose barb and used "steel wire reinforced vacuum hose" with a 1/4" ID because it resists kinking and collapsing.

  • What is the liquid input and output barb size on your 2.2kw water cooled spindle?

  • 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

  • Is there a recommended break in process for a 2.2kw water cooled spindle?

    A break in process, I'm guessing means if the spindle needs to be turned off for some reason? If so, then no. The water cooled spindle can be run constantly. We run our spindle for very long periods of time.

  • What length of wire do you recommend for the black toe (2'x4') between the spindle and VFD?

    The length of the cable from the VFD (Variable Frequency Drive) to the actual spindle should be about the same as the z-axis cable from the z-axis motor to the z-axis driver which is recommended at 11 feet. This is locating the VFD about at the midpoint of the machine.
