A question on spindles

Hey Nathan,

@Echd already provided you with a very good response.

There are industry-grade german ready-to-use VFD/spindle/control cabinet solutions (e.g. described in the video below) but they require a certain budget:

Or, you can buy a control cabinet assembled and configured ready-to-use:

CNC Finale: Automatic Toolchanger Spindle Install & Testing

Image: Shown is a full-blown control cabinet with VFD, circuit breaker, safety relay (red), and EMI filter on the left, and the pneumatics system for the automatic tool changer system of the ATC-8022-42-HSK25 2.2 kW 42,000 rpm water-cooled spindle on the right (and additional air tube (blue) with valve retrofit by video author which also wanted workpiece mist coolant – described in the video). On the back of the door you see the back of power switch, emergency button and reset button. Note the thick earth line that connects door to the rest of the cabinet.

So if you want to wire and assemble a VFD/spindle/control cabinet yourself, I add a collection of links below with some information that may help you.

What I think you should know in the first place are a few things:

1. If you buy a Huanyang HY series VFD (which is part of the cheap Huanyang spindle/VFD kits), this VFD has no sensorless vector control (SVC).(https://drive.google.com/uc?id=1-7zW33DPk80t8vYBqwfPjI9U4SrDRyA8) has this capability. If you ask me which VFD I recommend, please see Name brand vs Huanyang – Post #4 by Aiph5u.

2. Even if you want to wire your spindle/VFD/control cabinet yourself, I would recommend to buy a ready-to-use spindle cable and not make it yourself. For the reason and details, please see Where to get spindle cable – Post #1 by Aiph5u.

3. The power in kilowatts (kW) that you find on chinese spindle nameplates is often wrong. It may happen that think you buy a 2.2 kW spindle because they sell it with this statement, but in reality it’s only a 1.5 kW spindle. See here for details in order to be able to judge on kW statements on spindle nameplates.

Here is useful information if you want to wire your spindle/VFD/control cabinet yourself (I tried to sort them in a useful order):
