Kapp Technologies, Inc.

With more than 700 employees worldwide, the Kapp Group retains its position as a leader in the gear-manufacturing industry.

According to Thomas J. Lang, vice president and general manager of Kapp Technologies, in Boulder, Colorado, the company known worldwide for its gear-grinding machines and tools has its origins in a somewhat unexpected area: that of woodworking. “In the early 1950s Dr. Bernhard Kapp was a mechanical engineer who worked for a company called Waldrich, […]

Determining the Source of Gear Whine Noise

Relating gear pairs to manufacturing errors may lead to better designs for mated gears.

Gear whine noise, particularly in consumer products such as motor vehicles and appliances, is an important and annoying problem. This problem has been exacerbated due to the continual reduction in sounds from other system noise exciters such as motors, engines, and wind. In an effort to control gear whine noise, one must select both the […]

Fine Pitch Powder Metal Gears Using Stainless Steel Alloys


While the AGMA Powder Metallurgy gear committee has referenced 48 pitch as a working limit for fine pitch powder metal gears, production processes are now routinely being used to produce ultra fine pitch P/M gears with a pitch as fine as 96 DP. These gears would be difficult at best, in a steel alloy, but […]

The Power of Powder

Powder metal is poised to become a viable option for manufacturers seeking lower production costs and higher-precision gears.

Market demand for more cost-effective processes to produce higher-performance product continues to increase. To meet this reality, manufacturers who often still consider gear-cutting as core technology are being forced to look hard at those processes capable of producing net-shape geometry. After all, a large percentage of the cost for manufacturing a gearbox is tied up […]

Form Rolling for Finishing Powder Metal Gears

For many years researchers have struggled to refine the process of using powder metal to form lower-cost and higher-quality gears. Nissei describes its work in bringing that dream one step closer to reality.

In this article we introduce a finish rolling process for sintered Fe alloy gears using a new CNC form rolling machine: the Galaxy, which has been developed by Nissei Co. Ltd. The Galaxy is a two-roller dies plunge feed type in which seven axes are numerically and simultaneously controlled during rolling, reaching the highest precision […]

The Basics of Brush Deburring

Automated deburring systems help manufacturers save time and—most importantly—money.

Today’s marketplace offers a wide spectrum of needs for all types of manufacturers: from the job shops needing quick and easy changeovers for a wide variety of parts, to those who manufacture the same parts day after day. These parts can be almost anything manufactured, but very common in the mix are gears. All types […]

Tooth Tips: Donald R. McVittie P.E.

What’s the point in using precision pieces if they’re not mounted properly? These tips will help you to avoid the mess of misalignment.

Misalignment of an overhung pinion is easy to understand, but sometimes we see signs of misalignment even though the gear and the pinion are both supported between bearings. When pitting failure extends only halfway across the tooth face, it’s a sure sign of misalignment under load. What caused the misalignment? The key lies in the […]
