New Bond Improves Bi-metal Blades

L.S. Starrett’s process eliminates the heat-affected zone from saw teeth to produce a blade that lasts longer and cuts faster

Gage Calibration – When In Doubt Send It Out

Nothing lasts forever, and so it is with gage accuracy and repeatability. Drop them enough; subject them to the rigors of manufacturing plants, or mar their measuring surface...

Sawing Hard Materials

It is commonly accepted among metal sawing technologists that cutting steel hardened to Rockwell numbers in the 60s is a job for a diamond grit-edge blade -- not a regular band saw blade. However, Starrett has done just that, and this is the story.

Today's Optical Comparators

Although many may view Optical Comparators (also referred to as Optical Projectors ) as basic measuring technology, projectors have steadily evolved from simple comparative devices some 60 years ago to the more complex, precision optical measuring machines of today.

Granite Surface Plates

Manufacturers worldwide still rely on flatness accuracy to varying degrees, and so must properly select, install and maintain their granite surface plates. Yet, even with the advances in calibration equipment technology over the past 60 years, the basic plate has remained unchanged.

Wringability and Gage Blocks

Wringability is an important property of gage blocks. In fact, gage block specifications recommend replacing blocks that have lost their ability to wring.

Custom Gaging Considerations

Maintaining process control on products with complex shapes or even simple shapes with multiple characteristics requires custom gaging.
