Introduction:

Order the 2.2kW Water Cooled Spindle for more efficient, quiet CNC routing! Ships from the United States. Warranty & Support available now. High quality stainless steel casing. Speed: 0-24000 R/min.

Description:

We have tested spindles from many manufacturers and this spindle and VFD (Variable Frequency Drive) is the best one we have found. This spindle has four (4) bearings which will maintain the precision and extend the life of the spindle.

We support our spindles! We have qualified technicians with years of experience to fully support your needs or questions.

There is a connection to the spindle for power. Three of the four connections are used which connect to the internal coils that make the spindle spin. The fourth connection is not connected (NC).

Spindles need to be cooled and this spindle uses water for this purpose. More importantly, this aspect of water cooling does not allow air movement to cool the spindle (as opposed to routers that move air through the router to cool by convection). Water cools the spindle using conduction (heat transfer through contact). This is important because, as opposed to air movement, water cooling will not blow the dust all over the shop, and the dust and chips left over by the milling and cutting process can be removed with a dust collector or vacuum.

The ports for the water cooling tubes or hose is located at the back of the spindle. The port fitting will accept a tube or hose that has a 1/4" (.25 inch) inside diameter and an outside diameter of 3/8" (.375 inch). Either port can be used for in or out. It's just important that the water flow through the body of the spindle.

The sound level from a spindle is extremely low as compared to routers. In fact, the sound from a spindle is quieter than the actual cutting and milling action from the end mill, and much quieter than a router.

The spindle comes with a 1/4" (.25 inch) collet, which is the measure of the bore (inside diameter) inside which the shank of the end mill is inserted. the collet fits into the shaft where the collet taper matches the shaft taper. When the collet is inserted into this taper and the collet nut is tightened down, the collet squeezes around the shank of the end mill (helped by the way the collet is made with all of the sliced sections surrounding the collet). You will need two wrenches to tighten the collet nut onto the collet. Watch the video on the proper technique of loosening and tightening.

  • [2.2 kW (kilowatt) Water Cooled Spindle] 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.

How to Program Inverter / VFD

When Inverter is first powered on, there should be text flashing on the screen.

Step 1: Press "MODE" button. The screen should now say "P0"

Step 2: Use the UP and DOWN arrow keys to change the P setting to the desired parameter.

Example: To change setting P3-02 use the SIDE arrow to move the cursor. The flashing digit is the one currently selected. Change the digits using the arrows until the screen reads P3-02.

Step 3: Press "Enter" to input the parameter for the setting.

Example: After you have used the arrow buttons to select your setting, press the "ENTER" button and the screen will now change to the parameter. For instance: Setting P3-02 should be changed to 400.00.

Step 4: Change the parameter using the arrows. When you have input the correct parameter, press "ENTER" again to save your setting.
