Precision Gage Company

After 70 years, Precision Gage Company brings quality gear inspection to the industry, whether it be dimension-over-wires gages or fully-automated dual-flank composite test systems.

It’s a testament to Precision Gage Company that, from its beginnings in a living room in Chicago, it is celebrating its 70th year in the industry this year. Precision Gage has prospered by offering common-sense inspection solutions for manufacturing, especially with regard to gear inspection, according to RG Layland, director of business development for Precision […]

Magnetic Barkhausen Noise as an Alternative to Nital Etch for the Detection of Grind Temper on Gears

MBN is quantitative, repeatable, non-destructive, and it is easily automated, thus removing operator influence as a variable.

The detection and prevention of grinding burn is critical to the production of ground gears of all types and sizes. Overheating during grinding, or grind temper, results in undesirable microstructure, hardness, and stress characteristics both on and below the surface. These characteristics result in failure modes on precision surfaces, which typically require high performance under […]

Grading the strength of steel

Newly developed high-strength steel for car powertrain and transmission components includes three grades – knowing the difference will help you meet your quality goals.

Vehicle manufacturers are faced with a difficult task of significantly improving fuel economy and safety while maintaining competitive position in the market. This can be accomplished, among other things, by using higher strength steel for car and truck. Newly developed high strength steel for car powertrain and transmission components (GEAR-Steel) can help accomplish just that. […]

Measuring Tooth Flank Roughness

The Contact Stylus Profilometer provides a pragmatic, accurate and reproducible tooth flank roughness measurement.

Gear performance has continuously increased over the past two decades. Improvements in metals, heat treatments, geometry, and lubrication are just a few of the sources of these improvements. For gears operating in high load, EHL-type conditions, tooth flank finishes have experienced a similar improvement trend. These tooth flank finish improvements minimize the risk of surface […]
