Rancidity – the chemical decomposition of fats, oils and other lipids – happens when bacteria, yeasts and mold are allowed to multiply in metalworking fluids. The result is a foul odor, poor tool life, oxidation on the work piece surface and ultimately unhappy workers. Certain types of rancidity can also cause metalworking fluids to darken and stain parts, and neutralize the rust-inhibiting characteristics of the fluid.
Can emulsifiers cause Male Pattern Baldness? No health alerts this month, we're just kidding. Seriously - Emulsifiers are a critical component of metalworking fluids. They consists of a water-loving hydrophilic head and an oil-loving hydrophobic tail. The hydrophilic head is directed to the aqueous phase and the hydrophobic tail to the oil phase.

The constant increase in human life-expectancy is leading to an ever greater demand for implants and medical appliances. As these implants may remain in the body for 15 years or longer and are subject to constant cyclic stresses, high demands are made on the quality of materials used as well as on their internal and external surface structures.
After concentration, the most important measurable associated with Metalworking Fluid management is pH. This symbol is defined as the activity of hydrogen ions in solution expressed as a negative logarithm. Small “p” is the mathematical symbol for the negative logarithm and the “H”, or more properly the “[H+]”, is the chemical.
We don't really get Big Bird being on the cover, but the August issue of TLT magazine is a really fun read. It may fail to have provided a statistical base, but what it lacks there is makes up for with insight into the reader's opinions and the readers themselves. This is why fill-in-the-blank is decidedly more fun than multiple choice. In the issue TLT reports the response of Reader to these questions:
Change and challenge characterize the pace of life today. The world population is growing and the implications of the planet’s limited resources are hitting home at every level from the political and economic to the personal.
Initial days of my career I use to work as a Production Supervisor of a medium size Auto component manufacturing company having 10 CNC turning machines and 5 odd Vertical machining centers. It was an early morning, I was on my desk waiting for my first cup of tea for the day and the phone rings loud. It was the Quality Control Manager, before I could wish him Good Morning he orders "I want you in my office right now." I gathered all the courage and reached his desk.
