![]() Machining time was about 30 minutes for each electrode. A small cutter was needed (diameter 2 mm) to make the arrow shape clearly visible. Employment Opportunity / RFQ (Request for Quote). Machining has been done on LaHelis Optimum BF20 Vario machine with CNC upgrade.Quick Navigation Machinery Manuals / Brochures Top Here is a link to my build log if you are interested in doing a cnc conversion: The mill you have is very popular and there is a lot of info there for you. Optimum BF20 Vario Drill: Frequently-viewed manuals. You should check out the benchtop mill forum on CNCZone. You can also get a nice belt drive kit for that mill from Benchtop Precision. KB Electronics makes a controller that should work with that motor. I have a wiring diagram for the mill itself but unfortunately it doesnt show the circuits of the controls boards.Īny assistance would be greatly appreciated.Īny assistance would be greatly appreciated.I have the same mill and the first thing I would recommend you do is ditch the motor and controller. I have identified the other 4, 3 of which are D8020L 20amp, 800 volt diodes, and the other is a S6025L 25amp, 600volt Thyristor, but i have no idea what the blown up one is.ĭoes anyone have a circuit diagram of the actual rectifier/speed control board or could take a photo of one so I can identify the diodes, specifically the 4th device from the left in the row of 5 on the heatsink. Unforunately it has obliterated the front of the diode package so i cant see what type it is. It has blown up one of the diodes on the heat sink and is feeding very dirty power to the motor. Ive traced the fault to the AC-DC rectifier board, which runs the DC motor. I like to make things, so getting it working will be great. I've always wanted a mill to add to my collection, alongside my old Myford 6" Lathe and various other tools. I am an Electrician who has just been gifted a broken BF20 Vario mill. ![]()
