Frequently Asked Questions

These questions and answers are to inform you in an easy to read manner, not to confuse you with technical calculations.

Please contact us if you need specifics on any of these.

To learn more about metalworking fluids, read our Guide to Metalworking Fluids.

I am having a foaming problem, what do I need to do?

Generally, synthetics and semi-synthetics, made with surfactants, by their nature will tend to foam a little. The key is to pay attention to the dilution ratio.

Too much lubricoolant in the dilution ratio will produce a foaming issue. Reduce the ratio of lubricoolant, and increase the ratio of water.

If there is not enough lubricoolant in the sump, your pump can have a tendency to cavitate, producing major foam issue. Make sure pump doesn’t cavitate by increasing the amount of fluid in the sump.

If your flood coolant lines are small, and you have a powerful pump, that can create foaming. See if you can increase size of the lines.

If all of these steps have been tried and you still have a foaming issue, you may be using the wrong lubricoolant for the specific job at hand, please contact us.

I am having a rusting problem, what do I need to do?

Flash rust generally happens when there is not enough lubricoolant in the mixture. Recheck your dilution ratio.

If all of these steps have been tried and you still have an issue, you may be using the wrong lubricoolant for the specific job at hand, please contact us.

What dilution ratio is best to use?

Generally, metalworking fluids have a working range of (5 to 1) through (30 to 1).

Most times we recommend starting in the middle at (15 to 1), and then you can adjust from there for the specific job you are machining.

  • Grinding is best with a lean ratio (20-30 to 1).
  • Machining at (5-15 to 1) depending on the metal.
  • Sawing (5-15 to 1) depending on the metal.

This will also give you an idea of how much product is necessary to buy to fill the sump. If you don’t know the size of the sump you can use the equation:

L x W x H x .004329 = Estimated size of sump in gallons.

If all of these steps have been tried and you still have an issue, you may be using the wrong lubricoolant for the specific job at hand, please contact us.

How long will this coolant last in the sump?

With a regular maintenance/cleanup schedule, you can expect this product to last to your next cleanup. We have however had customers use our product for more than seven months, just refilling the sump with a make-up solution when needed. It all depends on the job and shop cleanliness.

A regular maintenance schedule would be every 3 to 4 months.

If all of these steps have been tried and you still have an issue, you may be using the wrong lubricoolant for the specific job at hand, or there could be other issues that will need to be examined. Please contact us.

How do I clean my machine and sump?

We manufacture a machine and sump cleaner to do that job. With the cleaner diluted to the specifications on the label, add to the sump and let the machine run for 15 to 20 minutes, and then drain sump. Wipe sidewalls of sump, with cleaner and under table if you can. Put new lubricant in and run machine. The new lubricant will also do some cleaning, so be prepared to clean again in a week. We also manufacture oil absorbent pillows and booms which will help keep your sump clean.

If all of these steps have been tried and you still have problems, there could be other issues that will need to be examined. Please contact us.

Can I put your coolant in with the fluid I am using right now?

If we manufacture the product you are using right now, then the answer might be yes.

If it is made by our competition, I will say no. We do not know the chemistry involved with our competitors products, and it is not advisable to mix chemistries. If your metalworking fluid were a soluble oil material, and you wanted to switch to a semi-synthetic material, as an example, mixing metalworking fluids does not give a good representation of what our products will do right from the start.

If you have questions on this, please contact us.

Can I paint my machined part right after machining it?

If your metalworking fluid is a pure synthetic, manufactured by Synthetic Lubricants, Inc., the part can be rinsed, and then sent to the paint booth. You would determine the amount of cleansing needed.

If you have any questions, please contact us.

Can I buy direct from Synthetic Lubricants, Inc.?

We only sell through distribution and catalog sales. We can however, ship direct to you through your nearest distributor. Please go to our distributor’s page.
