I have the HBM version on it, and the biggest problem with the one I have is the gearbox, which is plastic gears, stipped the changing gear a couple of times. The other problem is that the motor has very little cooling and no overtemp sensor. So that is on the healing bench right now. Like the machine, but if I bought it again I would install a proper tempsensor on the motor. and maybe an addisional fan.
Hi! Thankyou for your review. I’m about to buy one of these mills but I haven’t really decided if I should go for the 25 or the 30 version yet. Based upon your experience with this, do you have any hints to help me make my mind up?
Hi folks. Not all BF30's are the same. I have an Optimum BF30 and it is better in some significant respects. The mill column has a more substantial square cross section to start with. Variable speed but with three gears for increased torque at low speed and very much designed for CNC conversion - plenty of space for ball nuts. Later videos in this series show the table in this one being ground down and that is NOT a good idea - it releases stresses in the casting that can cause warping. BobUK.
The handle for the Z hight is for fast hight change, you then use the quill for fine feed. To get the fine feed to work on the front wheel you need to screw the centre knob in the drillpress like handle to convert from one to the other. I have not tried the high speed and always use the slower speed as you get more torque for bigger milling cutters.
Hi, i have the same mill as you. To use the quill fine feed you need to tighten the knob that is in the center of the three spoke handwheel. :) Then you can use the quill for fine feed as you did not like the coarse z axis feed.
Have you checked out the Little Machine Shop? They've got great lines of CNC upgrading kits among many other upgrade products for mini mills and lathes like quality tooling for instances, you should check them out and from what I've read the guys running that operation are very knowledgeable about machining and turning in general. Good luck with your CNC conversion and keep the videos of your process coming.
Jealous you have a mill! Machining is base of ALL manufacturing! Lucky enough to have access to a Bridgeport at my local makerspace! Not a my own cnc, but ones got to start somewhere!
@@michaelphone8739 aluminum will heat up quickly and gum up the coating. Uncoated end mills have a sharper edge that helps shear the aluminum without generating as much heat. In addition to the heat, coatings tend to have a rough surface texture meaning the ductile aluminum will fill the pours further adding friction and heat. Coating on end mills should purely be used wet.
dont measure runnout on random surfaces. thats a moot measurement. you only care about concentrically with the spindle. also, i bet your spindle has quite a bit of runnout anyways.

I think it’s time to custom print a few things for my next epic setup! Excited to see what you can do with this new toy!
was looking at an HBM 32 and came across your reviews about the HBM 30. nice and good review, thanks and good luck with the CNC extension. Arie

Have you check the MASSO system for your cnc ?
I know very little in that domain but for me it look interesting !

How does this machine fair milling steel?
It can do it no problem as long as you're not expecting crazy speeds or finishes.
is it can be mill to carbide ? or hss ?
Have you seen Mobasi?

processed material is aluminium or steel?
Aluminum
I use an ER25 collet chuck and full set of collets, I have never needed to use other tool holders or even a drill chuck. You'll need a lathe next :)

Thank you for this video!
This BF30 is my favorit if I by me a drill-mill for hobby.
Hey mate. Your video show as a restrict at my workplace's network. Maybe an issue of RUclips?
Must be some YT thing, I didn't set anything different than usual.
Thanks, helpful👌🏻

cool video! for aluminium use endmills without coating
