New member intro with spindle questions!

[JAZZCNC]

The first thing you should know and determine is that these spindles are quite heavy so you need to know your Z-axis can handle the weight.?

Next, most of these smaller KW 65mm spindles use ER11 collets which limit you to about a 7mm shank size, can you live with that, or do you need large tool sizes.? If so you will be better with the larger 2.2Kw versions which use ER20 provided the z-axis can handle the weight. ER20 will allow collets from 1 to 13mm.

You can get some of the 80mm 1.5Kw spindles with ER16 collets which have a range of 1 to 9mm but these weigh only slightly less than the 2.2Kw and cost only slightly less so are not worth the difference IMO.

Finally, does your controller/breakout board have a provision to control the spindle speed and on/off.?
If not then you can't use M codes to control the speed, you can use an Output if you have one spare to control a relay which in turn can be used for On/Off but if your controller/breakout board doesn't have 0-10v analog or PWM speed controller then you won't be able to control the RPM from software. You could use a serial/Modbus communication depending on the control software but that requires a serial to Modbus converter and software plug-in plus a little knowledge on how to set it up in the VFD/software.

Regards buying then I can't point you to a supplier of the smaller spindles but I can supply the Huanyang 2.2Kw WC spindle and VFD which we fit on the machines we build.
I have fit literally 100's of these so you can rest assured they are reliable and accurate otherwise I wouldn't use them.

These come as a set, both the 2.2Kw spindle and VFD are made by Huanyang, the set includes a 1 to 13mm collet set, 80mm spindle mount with bolts, water pump, and pipes. The only thing required is a container of water for the pump. £275 + postage.
I would also include my phone number for support and help with wiring, VFD settings, etc if needed.
