  • Does the 2in flexible strip brush also come in 4in lengths for the bristle?

    At this time, we only have 2 inch bristle length. How would you apply the 4 inch bristle? Would it be used for a CNC machine, or another application? We might be able to supply this longer bristly length if we can see a good market for it.

  • 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.

  • 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.

  • Your 2.2kw spindle w/inverter is out of stock for 110v, do you anticipate on offering these soon?

    We may deprecate these units as we had too many issues with them.

  • Do you sell the cooling solution for the liquid cooled spindle 2.2kw.

    We are going to add a cooling solution very soon to the website. I am awaiting inventory of Fan and Radiators.

    The cooling units that we will be offering are the ones shown in the two pictures here:

  • 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.

    Additional Information:
    You can program the VFD for low RPM only if the spindle will function at low speed without failure. What is the model of your VFD?

  • 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.

  • 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 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 is the width of your strip brushes?

    The strip brush is .2 inches (5.23 mm) wide, so a slot of that width or slightly wider will work. We use a .25 inch groove and use glue to adhere the strip brushes in our dust shoe.

    The material of the bristles and the strip that holds the bristles are nylon.

  • What should the "glue groove" width be for flexible strip brush?

    The width and height that we have on our brush piece for our cnc machines, is 1/4" width and .30" depth , the length is dependent on your specific dimension of brush and the design of the brush piece.
