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. 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.
Refer to this product page for the VFD/Inverter (Variable Frequency Drive) parameters and programming Spindle Wiring Diagram U -> Pin #3 V -> Pin #1 W -> Pin #2 Pin #4 is disabled. 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.
We do not make our own lead screw however, we can sell then in lengths up to 78".
will this fit a 2.2 kw spindle
Yes, this spindle connector will fit a 2.2kW spindle but there are a few varieties of connectors on 2.2kW spindles. confirm with the images that this is the correct connector. The connector varieties are different enough that the picture should provide a good indication of the correct connector.
what type of bearings are used in the 2.2 kW (kilowatt) Water Cooled Spindle
The 2.2kW spindle has 4 bearings in total: - two 7005 angular contact ball bearings and 25mm ID x 47mm OD x 12mm W - two 7002 angular contact single row ball bearings with the dimensions 15mm ID X OD 32mm X W 9mm
Does the spindle accept different collet sizes, or do I need to purchase different spindles that will accept different collets?
The 2.2kW spindle will accept up to 9/16" (a little over 1/2") end mill shanks down to very small diameters (any size that ER-20 will accept). The 1.5kW spindle has a reduced collet size and will only accept up to 5/16". The 1.5kW will accept ER-11 collets.
Would this spindle be able to cut steel or titanium or only softer materials?
The spindle is designed to cut non-ferrous metals, plastics, and wood. Steel and other harder metals require slower RPMs, and this spindle will only run at a minimum of around 15,000 RPM.
What size wrenches does this spindle take to tighten?
To loosen and tighten the collet nut for the 2.2kW spindle, I use a 22mm wrench (spanner) for the shaft and a 30mm wrench for the nut.
Is this compatible with a 2.2kW 220V Huanyang VFD? Thank you.
Yes, this 2.2kW spindle can definitely be used with a 2.2kW 220V Huanyang VFD as long as the spindle you select is also rated 220V.
How much does it weight?
The 2.2kW Spindle weighs 10 lbs.
