There's no single right approach to cooling - it depends on what you're doing and what you need.

The barrels of high sulfur oil, were bought from "Industry Depot" in 2015, sorry I can't find a current link or ph# for them. The other option that I had found at that time was the Hercules dark cutting oil, available from many sources in gallon jugs.

Sharing the knowledge you've aquired over the years, with the youth is an invaluable education and a process that needs to be brought back across all disciplines. Thank you . Most kids nowadays don't have the access to elders who want to mentor them . Not as many around as a century ago. The breakdown of the family and proliferation of immorality in society.is the cause. I'm sure you know that .

as a neat cutting oil i use one from fuchs , its a yellowish colour and it definitely has sulphur innit , i can smell it , smells like a rotten egg when i open the can to refill my oilcan , i have used some of the tapmatic trichloro ethylene based lube , i was tapping a m45 with a pitch of 5mm , this stuff really does wonders , boss didnt buy more and we had to do more of those big threads but used undiluted water soluble oil instead and ended up breaking the tapping wrench and needing 2 people to work together to actually turn the tap

The company i work for purchased a Climax portable lineboring system about a year ago. Nice machine. Paid for itself in no time. I operate a horizontal boring mill and had an 8 foot boring bar made up with square holes every 7 inches apart to hold a cutter. We bought some pillow block bearings and made up some other supports out of angle iron. Now i can line bore nicely . You're right. You can spend many thousands or get a little creative and come up with something just fine. Sometimes theres money in a job to justify the expense. And sometimes business is slow and you can experiment a little. Cheers from Canada.

I’ve been using air tool oil as cutting oil drilling holes lately because it was within reach. It actually works pretty well! Way better than the 10w-40 motor oil that usually gets used around here….

@MannoMax 8 ай бұрын

At the shop where i work, we have huge Gantry mills, about 5 meters by 8 meters table size. The mills and the parts we make on them are physically to big for liquid cooling, it'd get stuck in small cavities, cause rust, fires, and smell up the place. So they are cooled exclusively with compressed air, cutting both easy cutting stuff, like cast, but also tool steels and things of that nature. The only cutting fluid they use is dark cutting oil, they have it in watering cans like you use in a garden, they only use it when drilling deep holes into castings

I’ve been using Zep Lubeze Drill Chill for going on 14 years, it’s some incredible stuff. I’ve always hated how it smelled, but never knew about sulfur and chlorine. Just looked up the sds and sure enough, it has sulfur in it. It’s also really thin and creeps in when using it. It’s around $200 for 12 16oz cans, just found a place selling 5 gallon pails for $200, where other places are $350+. I don’t need it right now, but 100% buying it before it’s not available.

I started using ordinary canola oil for cutting. It is not healthy for human consumption, but environmentally friendly and seems to work for me in machining. It is inexpensive and when it smokes it smells like food fryer. Thanks to all the additives it never goes rancid and nothing grows on it. Built up cleans off easily with isopropyl alcohol or detergents, doesn’t interfere with welding. Worth trying.

Before machining I worked stucco & cement, absolutely no lung problems even without a respirator when mixing mortar/cement/basecoat. Before that I was an apprentice auto mechanic; 2 lung ruptures. Mechanics use a LOT of chlorinated brake cleaner and so did my shop. I'm only 22 and have had 3 spontaneous pneumothoraces and the only things they all had in common was the chlorinated chemicals.

@UbrShadow 8 ай бұрын

So as a question out of curiosity. What is the difference between cutting oils and honing oils? Furthermore has the need for lapping become something that is far more specialized?

@rok1475 8 ай бұрын

„The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.” So the lapping oil/fluid/compound is in fact a liquid or paste abrasive that grinds the surface. There is no cutter involved in lapping operation, the tools used for lapping push the abrasive suspended in the carrier substance to remove material. The cutting oil on the other hand is a lubricant that reduces friction between the cutter and the workpiece.

It was used right before the film dry cabinet on rollers that looked like paint rollers to remove the residue cyan dye. Whenever I went on the processor platform I would get a tremendous headache. I never figured out which chemical it was coming from. Then the EPA banned it and I had to get it disposed of (properly). My headaches went away. This chemical will not only kill your liver, but it’s cancerous. It’s a very serious danger to health. Never use anything that has it. Fortunately, you can’t buy anything new with it. The fact is that 1.1.1. Is slightly better for cutting, but really, it’s not that much better. Just stay away from it.
