Hello guys!

Some time has passed since we completed our first self-made CNC machine. We intended to build a router(mill) mainly for aluminium. We design, construct and produce custom machines...

@awerby, thanks for replying. You are not the first to mention endmills to be used in contrast to the special counterbore tools, I haven't tried that.

As for the spindle, it's not from the...

Hello folks.

I've recently had the situation to need to counterbore many holes in a 2000 mm (78'') part for screw heads. The through hole is ф6,5(1/4 '') and then we need to counterbore to 13...

Guys, thank you for your answers. In fact, now that I see others also employ end mills for precise holes, it seems, as I said and you confirmed, it's a matter of experiments with the right cutting...

Hello, thanks for your reply.

I've recently built a CNC machine which is somewhere between hobby and semi-pro level. It uses the ER25 chuck system so I can grab up to f16 mm(0.63'') tools.

I've tested the machine...

Hello David,

thanks for the links again.

I could determine from the picture in the PDF the position accuracy for GT2 pitches 2,3 mm by using proportions. It seems that pitch 2 mm is quite...

I am not too much into English...

Hello friends!
I am looking for theoretical information about clearance between the pulley and the belt for synchronious belts and actually for all models - T, AT, HTD, GT2 and other commercially...

Thank you both guys for the information and hyperlinks. These spindles seem to be more professional than the Chinese one but indeed the price is much higher(1.5-2.5 times).

Is there still...

Hello guys!

I am new to the forum. I am trying to select a spindle but am finding it very hard. My primary sources are AliExpress and Ebay.

Maybe my requirements are very high:
