Episode 90: Grinding out productivity

The Grinding Doc favors the Q-prime calculation over feed rates when assessing the productivity of a cylindrical grinding operation.

About the Grinding Doc Video Series: Thanks to his grinding courses and his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.

Wheel profiling machine from CUMI

The CDM series wheel profiling machine from CUMI is ergonomically designed with operator friendly features for applications such as dressing and profiling of straight and convex diamond or CBN grinding wheels mounted on a wheel pack.

Grinding medical tools with Eric Schwarzenbach, president of Rollomatic Inc.

CNC tool grinder manufacturers can offer application support to find the perfect mix for effective processes. Eric Schwarzenbach, president of Rollomatic Inc., discusses how the right partner can help.

Overcoming the challenges when precision grinding aerospace metals

Some strange light and soft metals used in aerospace applications have proven to be difficult to precision abrasive grind because they are stringy, gummy, load wheel surfaces easily, get hot quickly and have slow material-removal rates. These include stainless steel alloys and nickel-base materials.

Fine-tuning a grinding process

Usually, a grinding process can be improved by simply picking the low-hanging fruit. Grinding wheel manufacturer Meister Abrasives USA Inc., North Kingstown, R.I., recommends trying that approach first by selecting a single variable and significantly changing it.

What do you do when your orders outpace your production?

Since 1978, Moore’s Ideal Products, LLC (MIP) in Covina, California has designed and manufactured parts and tools for high-performance RC race cars. Recently MIP experienced a sharp increase in demand for their products, especially their world-renowned hex wrenches. MIP needed to increase their production without sacrificing the production or development of other products.

Optimizing grinding and dressing with 'dressing speed ratio' parameter

To achieve the quality and productivity requirements for most precision grinding operations, it is necessary that the grinding wheel is trued and dressed prior to grinding and periodically during the grinding operation. The truing process is initially carried out to correct for any wheel runout, create the required profile on the wheel, and condition the grinding wheel face.

Episode 89: Stop workpiece shapeshifting

The Grinding Doc examines the forces at work when cylindrical grinding produces round workpieces one minute, then something resembling a fried egg or a flower the next.
