I'm slowly gathering all the bits I need to convert my BF46 to CNC, one feature I want is rigid tapping and to be able to thread mill.

While the existing spindle motor is a DC motor I have been...

I got the ballscrews through Scott Machinery in Christchurch, all the ballnuts bolt to the existing mounts which will make mounting really easy.

If I manage to get the price of the bare cnc...

The Mitsubishi servo motors I have (6 in total) are a mixture 3 x HF-MP73k and 3 x HF-KP73, the only difference I can see are the MP's are ultra low inertia and the KP's are just low inertia which of...

See highlights above

Well I've been too busy to actually do anything apart from accumulate the parts required for the conversion, ball screws, Mitsubishi 750w servo's plus many of the other parts including the cabinet...

Hi Gav thanks for the thread would like to meet up sometime when I'm in ChCh (I live in Dn) I have one of Scott Machinery's BMV54 Mill Drill's I want to convert to CNC using servo's and also want...

Flexo thanks for the reply, a 10kw motor sitting on the head might be a bit of a push.
I was hoping to get away from the noisy gear drive (gets a bit annoying after a while) so perhaps a 1:2. 2:1...

I have a Luxcut BF 54V (which is a rebadged Optimum BF46) which I am accumulating the necessary hardware to CNC this machine.

I am going to use DMM servos, a set of ballscrews by RSK which will...

After reading this thread again I might have to go and pull the motor cover off mine......just to see if it is three phase, I had always assumed that it was three phase and ran an inverter for the...

I have a T&C grinder similar to the one shown in your photos. Is yours single phase or three phase?
I have found a similar one which shows pics of all the attachments
CHI TSENG MACHINERY IND. CO.,...

I'm interested in your conversion and have been thinking that when I get time I will convert my Luxcut BF54V which is the same machine as yours. Mine came with DRO, power feed and coolant.

Well nothing much has happened since my last post apart from a well deserved holiday..........anyway I got home from holiday and my ball screws have arrived for the BF46.

Also while I was away the...

I ordered the ball screws today, Chinese precision ground ball screws with an accuracy guarantee of 0.005mm. These will bolt straight in.......now all I have to do is locate a servo kit to fit to it....

Thanks Pat very helpful information.

Does anyone know of a servo kit that is available, and will Mach3 run servos?......Kiwi

Thanks, yes the stepper motors are 12 n-m which equels 1700 in-oz. I would like to setup a closed loop servo control with similar torque.......does anyone know a servo kit of this size that is...

Well I've lurked here for quite a while and when I bought my Mill Drill I had the intention of converting it to CNC at some point.
The Mill Drill I got is a Optimum BF46 with 40 taper spindle and...

Thanks Phil,
That 3100 euro price tag for the CNC kit is more than I paid for the mill, and my mill has the table power feed and 3 axis DRO. I bought it new 6 months ago for about US$3200.
I am...

Has anyone come across one of these before? I am thinking about converting one to CNC.
