Installed a Vertex flood cooling kit and a generic China brand mist cooling kit on my Optimum Optimill 50V mill yesterday.

Put one on each side of the head and routed all the hoses through the stock cable tray which came out okay.

Bought a tool board bottle holder and slightly bent it so I could use it with magnet mount. Now the coolant bottle for the mist cooling has a proper mount too that can be easily removed.

That looks like a nice machine for it's size, and nice to have both cooling options. Mike
 
Thanks!

I've had the flood cooling ghetto rigged for sometime and for some operations it's nice but for the most part it just creates a big mess. I'm hoping the mist cooling will be a cleaner option for those situations where all I want is to remove the chips from the slots.

I actually ordered the smaller Optimum MH 30V machine but after waiting several months for delivery and then getting a partially defective machine they sent me the slightly larger MH 50V model instead which was a big upgrade as BT40 tool holders are much more common than the smaller BT30 ones.
 
Unlogic what is your opinion of the Optimum MH 50V, are you able to do a review of it.?

I'd say this is a pretty solid machine given that it's made in China. I've had the machine for about a year now and I've slowly scaled up the size of the parts I've milled over this time.

With the flood and mist cooling in place ałong with a chip guard I've recently added I can finally start to churn out some bigger parts.

I could probably have a review done in 2-3 weeks time. I've thought about making a review before but couldn't figure out which forum section to post it in. Do you have any suggestion where it should be posted?
 
I’m not sure where a review should be posted, but will give it some thought.

After looking at the manual for the MH50 it seems to be a replacement for the BF46 (BF46) as they both have very similar specs.
A bit after the BF46 came out Optimum marketed a cnc machine based on it and called it the M4 CNC, I wonder if they will market a cnc version of the MH50.

I like the power feed setup on the MH25SV and have thought the use of servos for power feeds with a simple controller would be a excellent idea.

it would be good if you could do a review of the MH50 as I would really like to see that.
 
What is the actual Z travel and with no tooling in the spindle are you able to lower the head to the bottom of it's travel and not hit the table with the spindle?
 
I've finally had some time to start doing some larger projects on this mill so I renamed the thread to "Optimum MH 50V mods and accessories" as I'll be posting a few more mods in this thread.

I tested this today and the spindle goes very close to the table, I didn't have the balls to push it any further because it was compressing the Z-axis way cover quite hard at this point.

I couldn't reach the highest setting either because the spindle motor hits the roof in my garage.

So on the photos below there is a few centimeters of travel left upwards on the z-axis.

But given these restrictions I got just above 50 cm of Z-axis travel. If you count all the way from the table to the top of the Z-axis to true travel is probably somewhere around 55 cm.

If you want more detailed information about this mill and how it's built there is a great thread in German here of the MG 50G model which is the same machine but without VFD drive of the spindle motor:


A company called Mobasi also sells this machine preconverted to CNC:
