Our shop is in the middle of an ongoing significant discussion regarding the use and maintenance of our coolant.
We are a very large machine shop with every variety of machine tool a shop should have. We have a few hundred employees and a designated "coolant team".
The discussion we are currently in is the "team" has been trying to sway us from using HOCUT 795 to Castrol syntilo 9913/9918. Most all of the employees enjoy the houct over the syntilo, ill try to lay out my understanding of the general opinions.
Hocut:
works great as intended for all materials.
minimal evaporation so rarely need to top off.
some individuals complain of skin iritations if coolant is not properly maintained.
Coolant does seem to go bad if left in unused machines for long periods. (some machines will sit for months with no use)
There is little to no residue or rusting of parts.
Machines show no "wear" from use.
Synitlo:
works well as a coolant.
we experience extreme atomization and not all machines are equipped with mistbusters, so topping off can be as much as 10 gallons per machine per shift.
same skin irritations if not properly maintained.
coolant works well when sitting idle for long periods.
parts rust and corrode frequently if concentration is not maintained well, which can be difficult with the amount of evaporation/atomization happening.
when the concentration gets too high it is stripping the paint and seals off of the entire machine. We have two same era machines that were on hocut, one was switched to syntilo and within a month looked 10 years older.
I am not sold that Hocut is the perfect coolant to use but I feel its the better of the two. I am not sure why we cant try other more known coolants this is something I am working on. I find it strange that there are few people running syntilo in the real world.
One item I think is a huge challenge is the coolant teams attempt at recycling our coolant for cost savings. It seems most shops just cycle out the bad and put in fresh. Our team is attempting to reuse bad coolant with just agitation and skimmers.
To me it seems the emulsified will handle the poorer care and set up better than a synthetic as far as water condition, tramp oil removal and lack of machines with a mist catch system.
I am looking for general input to bring to the table regarding emulsified vs synthetic and the criticality of maintaining each in a certain way. which might work best with less than ideal maintenance. And also on the recycle side of things, what is needed to produce true "clean" coolant that has been used but gone through the right treatment process.
Thank you.
