Controlling the growth of bacteria and fungi in metalworking fluids is an ongoing concern for businesses. Since bacteria and fungi live primarily in the buildup on the floor and walls of the sump, good cleaning practices are a cornerstone of machine tool sump maintenance.

An effective coolant delivery system can improve tool life and surface integrity, move chips or swarf from the cutting zone effectively, and provide temporary corrosion prevention. An ineffective coolant delivery system can cause tool failure due to thermal shock. But what makes an effective coolant delivery system? Read our technical bulletin to find out!

Spray mist primarily serves to take heat from the process and is mostly done as an alternative to flood or high pressure coolant delivery when the machine or operation doesn't allow for the free flow and return of fluid in volume. While all spray mist equipment is quite similar in function, its set-up and maintenance are critical. Read our technical bulletin all about spray mist and its unique characteristics!

Gun drilling, also called deep hole drilling, was initially developed for drilling dependable, uniform holes for rifle and gun barrels. Today, it is still used in the manufacture of armaments as well as a variety of other industries due to its numerous advantages. Read our technical bulletin to learn all about gun drilling and its many advantages!

Ammonia blush is the outgassing of anhydrous ammonia from a system under pressure. It happens when a specific set of changes to the pH occurs. A similar phenomenon, amine rush, causes the release of a pungent odor similar to the ammonia odor. While neither problem is generally a health and safety issue, ammonia blush is frequently a symptom of underlying bacterial control issues. Read our technical bulletin about the conditions that produce ammonia blush and amine rush, and find out how to reduce or prevent them!

The standard definition of biodegradable is "capable of being broken down especially into innocuous products by the action of living things (such as microorganisms)." In the North American metalworking fluid market, the claim "this product is biodegradable" implies that the product can be "dumped" into sanitary sewers without problem - and this, of course, is NOT TRUE. Read our technical bulletin with a detailed and accurate definition of biodegradable!

Disposal of metalworking fluid waste is an issue that all the companies that we work with face. Whether they choose offsite disposal or on-site treatment depends on a number of factors, including cost, type and volume of waste, and local sewer department restrictions. Read our technical bulletin that gives an overview of waste disposal and treatment options in our technical bulletin!

Though Master Fluid Solutions and much of the metalworking fluids industry stopped using nitrides in the manufacture of their cutting and grinding fluids, it doesn't mean that getting a"positive" test for nitrides is impossible or even improbable but it does mean that some investigation is in order. Read our technical bulletin to find out how to identify the source(s) of a positive nitride reading!

The use of nitrites in combination with amines in metalworking fluids is regulated by the U.S. Federal Government and it is advised that amine containing materials should not be allowed to combine with fluids containing nitrites. Read our technical bulletin to find out more about the subject of nitrites and ensure nitrite containing fluids are never used in any situation where amines could come into contact with them!

More than seventy years of making and servicing metalworking fluids has taught us to look to a relatively short list of issues when trying to pinpoint the cause of dermatitis. This list of possible causes, though not all inclusive, covers more than 95% of all cases with contact with contaminated, "used" working solution, or another non-fluid related issue being right at the top of the list. Read our technical bulletin to learn the main issues causing the majority of dermatitis cases!

The Hazard Communications Standard is a federal regulation that sets forth what minimum levels of health and safety information to provide employees and how that information is to be delivered. Read our technical bulletin to refresh your knowledge of the four key areas of hazard communication!

When properly used, biocides and fungicides, technically called 'antimicrobial pesticides', are very safe. However, these chemicals are designed to kill living organisms, so they need to be treated with respect. Read our technical bulletin for a detailed explanation on the proper use of the biocide or fungicide from a health, safety, and environmental perspective!

We do everything possible to formulate and produce fluids that do not cause dermatitis. So why then are coolants so often implicated in industrial contact dermatitis? The answer is that the fluid in use is often very different than new fresh fluid, because of either improper management or contamination, or both. Additionally, it is the part of the process that is least understood; so when no other explanation is found, the coolant often is blamed.find out more about dermatitis and its main causes!

Since "used metalworking fluids" are often implicated in industrial dermatitis cases, it is important to understand what can be done to protect workers from potential irritants. There are in fact some relatively easy steps that can be taken to reduce the risk of dermatitis. Read our technical bulletin to read our tips on reducing the risk of dermatitis based on our 65 years of experience working with metalworking fluids!

Metalworking fluids in general, and water soluble products in particular, are hard on machine seals because of the complexity of their formulation and the large variety of chemicals used in their formulation. What's more, there are no standards for metalworking fluid seal swell compatibility. Read our informative technical bulletin to find out more about seals and sealing and their relationship with metalworking fluids!

The window into fully enclosed modern machine tools is there to let you check inside while keeping the enclosure sealed. The selection process when choosing a material for the window should involve care and consideration. Read our technical bulletin to find the pros and cons of different materials for your machine tool's window!

It is estimated that over 50% or more of all machine tool maintenance downtime is related to lubrication issues. The proper selection and use of grease and lubricating oils is therefore critical to productivity as well as machine tool health. Read our technical bulletin to find out the main issues associated with the selection of these oils and how to overcome them!

After more than seventy years in the industry, Master Fluid Solutions has found that the cause of a corrosion problem can frequently be traced to a relatively short list of reasons. Read our comprehensive technical bulletin with a detailed list of problems that lead to corrosion!

Differentiating between corrosion, staining, and residue is critical when combating corrosion. This is because these three problems - often "lumped" into the same basket on the shop floor - have very different solutions. Read our technical bulletin to find out more about the important differences between corrosion, staining, and residue!

Tramp oil is the name given to oil that gets into metalworking fluids unintentionally. These tramp oils are one of the major killers of metalworking fluids because of how they chemically change the fluids and affect the ability to accurately measure concentration. Read our technical bulletin about how tramp oils get into the system and the problems they cause!

By their very nature, metalworking fluids, whether water miscible, straight oil, or parts washing fluids, tend to be subject to biological contamination. This contamination can come from a variety of sources and presents itself in a wide variety of problems in metalworking fluids. Read our technical bulletin to read about the different problems bacterial contamination may be causing!

With water representing more than 90% of a metalworking fluids working solution, water quality is critical to ensuring the best possible working solution. It is, therefore, critical to make sure the quality of the water is as high as possible. Read our technical bulletin for a comprehensive look at water quality!

One of the most basic rules of design engineering is that to make a good product, you must start with "good" raw materials. Therefore, when working with water-miscible metalworking fluid, high quality metalworking fluids and water are key. Read our technical bulletin about water-miscible metalworking fluids and how they are mixed with water most effectively!

Recycling metalworking fluids is not like recycling aluminum cans or newspaper, where something without value (a can) is made into something of value. Instead, by using good fluid management and recycling techniques, it is possible to extend the life of metal removal fluid virtually indefinitely and the life of parts washing compounds by many orders of magnitude. Read our technical bulletin to find out the components that make up an effective recycling system!

Microbiological growth is to blame for many metalworking fluid problems but luckily it can be controlled using a variety of techniques. These techniques aim to control their growth and reduce the negative impact they have though it is not possible to completely remove them from the metalworking fluids. Read our technical bulletin with an extensive list of tips on how to reduce the growth of bacteria and fungus in metalworking fluids!

The two most commonly asked questions about metalworking fluids that require some math to answer are: 1. How big is that sump, tank, etc.? Meaning how many gallons or liters of fluid does it hold. 2. How much fluid should I add to that sump to achieve the desired concentration? Read our technical bulletin and be ready with the answer the next time you are asked these questions!

Tramp oils in a metalworking system are major contributors to metalworking fluid failure and enter the machine from a number of sources. Generally speaking, the amount of damage done to a system by the presence of tramp oil is directly proportional to how much tramp oil gets into the system, how long it stays in the system, and how tightly it is held in the system. Read our technical bulletin to learn some tools and techniques to remove tramp oil from a machine!
