Unboxing the G-penny BST-2.2C-80-24K, man this thing is huge and heavy.
If the side by side comparison of the collet nut vs the Makita’s is any indication:
First thing I checked is the runout inside the collet taper: it is below the rated precision of my dial indicator (0.01mm / 0.0004"), visually it looks like it could be ~0.005mm / 0.0002". We’ll see how much I get at the endmill level using the provided ER collets.
The packaging was quite good, lots of protection. The inverter comes with a 60 page user manual in what looks like decent English. So far so good.
There is however a MAJOR issue: the blue of the spindle does not quite match the blue of the BeaverCNC mount
The user manual does not seem to have any interesting power/torque/speed curve, but honestly I did not go through it yet. I found it online as a pdf if you want to have a look
That’s the VFD manual so it wouldn’t have info (power/torque/speed curve, etc.) on the spindle/motor (which is required to setup the VFD properly). That relatively light weight, the fact that the case says “220V, 10A, and 2.2kW”, and 220V X 10A = 2.2 kW makes me wonder if the 2.2kW is the input rather than the output power rating - as it should! It should be plenty powerful enough anyway, but you’ll need to know how to setup the VFD for the motor.
I checked the claim that the spindle is grounded, and indeed the 4th wire (pin 4 of the aviation connector) is connected and has continuity with the spindle body (I checked with a multimeter). Good.
@Julien "the input 220V power plug I will use has live, neutral, and earth."
So 220V 50 Hz line voltage (hot to neutral - which is apparently earth referenced somewhere) is the French residential standard utility power? US’s standard is two 115 V 60 Hz line voltages (hot to neutral - which are earth referenced at the service panel) that are 180 degree phase shifted (for 230 V phase - phase voltages for high power loads). Interesting! I wonder if the 50 Hz transformer/ballast buzz is as annoying as 60 Hz is!
@fenrus
380V 3 phase provides 219V line voltages - which is good. Most 3 phase in US is 208V (maximum) which gives 120V line voltages - which is good. But the phase voltage is only 208V which isn’t really high enough for many moderate single phase 220V - 240V loads like motors! And we’re still stuck with the imperial measurement system - I had to figure out what a “slug” is the other day!
I’m about to order the HDZ for my XXL. I’m looking for a complete water-cooled package as the one mentioned here, but I need it 110Volts, instead of 220Volts. Or, should I be getting 220Volts? and if so, whay? I sincerely appreciate your help, thank you.
Do you really think the Soviets would have allowed the U.S. to get away with faking it?
You do realize that there was never any sort of conspiracy theory about this until the movie Capricorn One was released?
There’s a mirror placed on the moon by astronauts you can bounce a laser off of to measure the distance to the moon — that experiment used to not be possible — that it is now, is proof.
