Precision spindle for Proxxon MF70

Again upgrade of Proxxon MF70. Precision spindle this time.

[@isidoromaich7226]

That mod made it even better... Maybe there's still room for more improvements? who knows? To my knowledge, you are the only MF70 expert on all of KZbin.

Yeasterday, the motor on my milling mashine, the same type as yours, gone broken and your modification is a great perfection using the belt and that castle creation brushless motor.

Good morning, I think that a good improvement would have to be with the original work table of the machine, I see that a new Proxxon brand of a more professional milling machine was acquired, which I do not see as valid, there are countries where acquiring these components is too difficult

[@colbyhuang8737]

Do you have any advice on removing the original spindle bearings?

[@liviutum1]

Nice upgrade. Can you add a part list needed for changing the shaft?

[@zhadlun]

Basically only a shaft and maybe bearings. But then you will need to make something with engine. In my case I have also replaced engine. You could take a look in this video, how everything made inside kzbin.info/www/bejne/qX6YfKSEnsaYfrM

@@zhadlun Ох мнеб так же, Волоримир. Очень хотелось бы такой же стержень, что по точнее, ну и конечно конфигурацию с редукторной шестерёнкой (с другого видео), что конвертирует скорость в мощь. Если бы вы приняли заказ, во сколько обошлось бы мне это удовольствие? Заранее благодарю за ответ.

[@sinadaneshkhah8537]

Thank you for sharing your video with us. But easily was possible to remove run out whith grinding because 0/01 or 0/05 also 0/10 mm is not much and white grinding will be exactly ziro. Normally when you buy some accessories for lathe or milling machine of course are not correct and fit white your lathe but machinist must Fix it. Any way thank you again. Best regards sina von Österreich 🇦🇹

[@zhadlun]

With spindle yes, possible to fix with grinding, but then I need also take care about tapper there. Not sure I will be able to do better than it was. But how about a collet. Grinding there will not have a result in my mind…

[@kentpranata903]

What is the diameter and length of the original spindle?Thanks

Hey, where did you get that cnc plate as motor mount ?

I bought them some time ago, will need to found updated links to a products. You could just look for er11 collet with 10mm shaft 150mm long. Endmills, any with coating would work.
