Tech Tip: Proper Coolant Mixing Practices

Posted by Lube-Tech on Jun 26, 2018 9:45:24 AM

When machining with water-soluble coolants, maintaining coolant stability is essential to produce quality parts and surface finish. Therefore, it is important to mix the coolant properly. 

Water-soluble coolants consist of both an oil phase (nonpolar) and a water phase (polar). These phases are extremely dissimilar, so they tend to separate from one another. Hence, emulsifiers are an important component in the coolant concentrate. Emulsifiers are molecules that consist of both polar and nonpolar sides, which help bring the two phases together.

Tech Tip: Importance of Water Quality

Water plays an important role in maintaining the integrity of a metalworking coolant. Water makes up roughly 95% of the resulting dilution, so its chemical state has a great influence on how well the concentrate mixes and forms a stable emulsion.

If water quality is poor, a wealth of issues can develop. These issues include corrosion, poor machining performance, and water spotting on finished parts. Testing water quality is the first step to ensuring proper performance.

Tech Tip: Foam Control

Foam in a metalworking fluid  system is unconducive to the machining process. First and foremost, air does not provide lubricity or cooling to the workpiece. Additionally, air entrainment can promote premature pump failure and create spills - both of which generate significant downtime. Determining the source of a foam issue can ultimately fix the problem and relieve the headaches in the workplace.

Tech Tip: Cleanout Procedure and Fluid Maintenance

Posted by Lube-Tech on Jun 26, 2018 8:32:12 AM

A clean metalworking fluid system provides better machining, surface finish, and tool life than a dirty system. Metal fines, bacteria, and tramp oil are all problems that can escalate over time, each of these can warrant a cleanout.

Sometimes a cleanout is inevitable, but proper coolant maintenance can help prolong sump life. Before a system is cleaned out, a sample should be sent to the Lube-Tech lab to determine the potential mode of failure.

Tech Tip: How to Use a Refractometer to Determine Concentration

Posted by Lube-Tech on Jun 26, 2018 8:22:37 AM

Some fluids utilized in the manufacturing industry are water-dilutable coolants, which are oil-in-water dilutions used for machining. Coolants must operate within a specific concentration window to maintain the right amount of lubricity and additive content.

Refractometers are instruments used to obtain a °Brix reading, which measures the oil content present in a coolant mixture. Additionally, each coolant refracts light differently and therefore has its own specific multiplier, called a refractometer factor. The °Brix reading can be multiplied by the coolant’s refractometer factor to determine the coolant concentration.

Mobil Delvac 1300 Super 15W-40 CK-4 Claims

Posted by Lube-Tech on Jun 25, 2018 3:19:41 PM


Recently, ExxonMobil received notification that Shell claims Mobil Delvac 1300 Super 15W-40 does not meet API CK-4 nor OEM performance expectations for the Volvo T-13 engine test. ExxonMobil wants to assure customers that Mobil Delvac 1300 Super 15W-40 carries valid OEM approvals and API CK-4 licensing, which includes passing the Volvo T-13.

ExxonMobil will diligently investigate Shell's accusations and is well-positioned with a fundamental understanding of the Volvo T-13 engine test, as ExxonMobil provided technical leadership in the Volvo T-13 test. 

Automated Lubrication: The Key to Increasing Efficiency

Posted by Lube-Tech on Jun 25, 2018 3:09:54 PM


More than half of bearing failures are the result of improper lubrication. Shops know that bearing replacement can be costly, and lost production time can multiply those costs. The majority of bearings are lubricated manually, which typically means the machine is stopped and a worker is physically applying grease, resulting in machine down time and often less than ideal lubrication application. Automated lubrication systems can take the guesswork out of machine maintenance, decreasing down time and increasing a shop’s bottom line.

Tech Tip: Lubricant Storage & Handling

Posted by Lube-Tech on Jun 25, 2018 3:03:06 PM

With increased health and safety regulations surrounding lubricants, it is important to put an emphasis on practicing safe and effective lubricant storage and handling procedures in an industrial environment. These practices will ultimately ensure proper lubricant use, reduce the risk of cross contamination, and improve occupational safety.

What You Need to Know About API SN vs. SN Plus

Posted by Lube-Tech on Jun 25, 2018 3:02:47 PM

Increasing fuel economy and emissions standards continue to drive automotive technologies, and those technologies are placing higher loads and demands on lubricants. OEMs are demanding engine oils that assist them in meeting fuel economy and emissions requirements while protecting engines through the life of the vehicle. Idle stop, low-speed pre-ignition and turbocharged engines are just a few of the protection challenges in front of modern automotive engine oils.

The pending ILSAC GF-6 engine oil specification is intended to address the issues arising from emerging technologies. However, with timing getting pushed out to 2019 or 2020, API updated its SN rating, releasing the SN Plus oil classification as a stop gap.
