West Michigan Spline

As a young man he experienced Detroit’s productivity at its peak, and he has since managed to carve out his own “small niche in the world.”

As a teenager he was working at a hamburger joint in the early seventies when he got to know a couple of guys who came in for lunch a few times each week. A senior in high school at the time, they offered him a job once he’d graduated, which he eagerly accepted. The company […]

Hard Fact of Hard Rack Milling

The following paper concludes that hard rack milling for finishing hardened racks provides the same level of accuracy as rack grinding, with lower costs and shorter cycle times.

Rack gears used for rack and pinion assembly are often hardened to increase durability. In most cases a finish grinding process is necessary for correcting the distortion of racks after heat treatment. If the hardened gear racks are finished by milling instead of grinding it will increase productivity and cut production costs considerably. The major […]

Better Broaching through Process Control

Those concerned with streamlining their broaching process will appreciate the following step-by-step description of aspects to be examined, understood, and improved.

Is your broaching process capable and predictable? Many are not. This article will discuss why and how performance metric based management can help bring your broaching operation into control. Predictability and reliability are desirable in every operation in the factory to create sustained value. Find an unstable process and you’ve found heartburn for managers. This […]

Protecting Gears in Wind Power Applications

The following article, presented by lubrication experts with Kluber, discusses the benefits of high performance oils for heavily loaded gears in wind power stations.

In wind power stations, both fluid (lubricating oils) and consistent (lubricating greases) lubricants are used. The main task of the lubricant is to ensure reliable operation of the machine elements. Important lubrication points in wind turbines are in the main gear drive, the yaw system gear, the main and generator bearing, the pitch adjustment unit, […]

Terry McDonald: Site Safety

With a new administration comes the potential for changes being made to OSHA regulations, so be sure to check online for any updates so that you'll be able to achieve safety compliance.

Well, now that we have a new presidential administration you have to wonder what it’s going to mean to us in the realm of safety. Are the OSHA requirements going to change, or be better enforced? Is there going to be more emphasis applied to workplace safety, and what about ergonomics? Are there going to […]

Corrosion alone can lead to gear failure, but when you add fatigue loads and consider materials and temperature, you’ll realize this natural process shouldn’t be ignored

How many engineers know that corrosion is generally regarded as the prime cause of failures? In 1986 Batelle Labs estimated the annual cost at that time of $186 billion dollars—4.2 percent of GNP. Gears, roller bearings, and cams all corrode from the same sources and are not immune to this problem that is now receiving […]

Chris Chlon: Buy Laws

Before awarding business to a small company—or to anyone, for that matter—one must balance evaluating capabilities with encouraging innovation from which you can benefit.

Occasionally a really good idea comes up when working on a project. It might represent a faster cycle time, streamlined process, or a real process improvement. In today’s manufacturing environment the pressures for making things faster, cheaper, and better are relentless. However, what appears to be a great idea for reducing cycle times or for […]
