Does anyone have any recommendations on a better coolant for the MR1? This stuff mixed correctly is awful. It etches aluminum badly. It turns into maple syrup over night. It coagulates in the drains and holds metal chips like varnish in the drain holes. There has to be a better alternative to this crap? The whole machine, windows, doors, carriages are covered with a film. Its taking more time to clean up the machine than make parts…
Sorry just venting !!!
I’m going to try this stuff. Our shop has been using it for 10 years . Rinses off with water . Machine is cleaned with water once a month, it’s been close to a month since last cleaning. The rest of the time operator use compressed air to blow everything down at end of shift
We used Castro hysol. Would clean the windows and table/vices with crc 3-36 and any residue would come right off. For YouTube cred you wanna go with swisslube lol boom. (I’m sure it’s a great coolant too)
Hello, I have a question. I just getting to the facing the base plate stage and just got the coolant tub set up. I new to this and not sure how much water/coolant I should put in the tub. Also, did everyone use coolant when they faced the base plate or can you do it dry? Just trying to get my machine going here.
Hey, that looks just like mine. We can’t say they don’t looked used now. I have experience with Qualichem 251 in my 30 year old Hurco and it worked well. No sticky residue. Parts and vise were nice to work with, after a quick blow with air. May change over but just bought a extra gallon of the Universal, to keep the mix correct for now.
I bought coolant with the machine and will probably use it initially. At work we use Nusol Alumax with our Haas so I may try some of that in the future. Main thing is to keep things rinsed and blow dried.
I’ve also heard a lot of good things about Blaser Swisslube.
The “stock” coolant was in the machine for all of 2 days and I knew it wasn’t going to work. I had the same staining issues as others even on parts that were blown off and wiped down after machining. The sticky residue was also a huge annoyance because I couldn’t clean it off without something like brake clean.
I picked up the Qualichem stuff from my local machining supplier and mixed to a 8% mixture. So far so good. Better surface finishes in the cuts, no staining, blows off parts easily. It will leave a sticky residue if you leave it to dry but it washes off as soon as you touch it with more coolant or water so cleanups are very easy. It’s also significantly less sticky when it drys and I see it more as a rust preventative on my vises at that point. At the end of each day I’ll blow off all the machine surfaces, push the chips to one corner and by the next morning I can shovel them out without any wierd residue on them.
You can see here how this stuff doesn’t seem to want to cling to everything it touches like the stock coolant which is why it’s so much easier to blow off of things
Left this freshly machined block of aluminum in the vice (wet) for 2 days. The coolant did get a little frothy while doing a deep pocket clearing. Most of it dissipated over night. No syrup drops, it does leave a thin film which wipes of easily. Chip cleanup much better. I will definitely be using this over the Universal and recommend this product.
