Company Profile: Nachi Machining Technology

Faced with a faltering economy, changing product designs, and new challenges from developing countries, Nachi regroups to remain a leader in the gear-making game.

Years ago, as the story is told–and long before Nachi-Fujikoshi purchased the 76 year-old National Broach & Machine Co.–a certain gear worker began setting the company’s machine tools apart from the others by painting a red ring around them. Asked why, he said that they worked the best, and he didn’t want to lose sight […]

The Basics of Rebuilding Machine Tools

Why retire a perfectly good machine tool that may still provide years of useful service life? The following is a step-by-step outline of "How to make cents out of it."

Rebuilding a machine tool requires expertise in mechanical, hydraulic, lubrication, pneumatic, electrical, control, and coolant systems, as well as knowledge of the process the machine performs. The rebuilding process will require each of these systems to be disassembled, cleaned, inspected, and repaired or replaced as required. A complete rebuild process takes place in a series […]

PVD Coatings for Improved Gear Production

Not only do PVD coatings extend the life of your gear-cutting tools, they can also impart beneficial properties to the actual gears being produced.

Low-temperature Physical Vapor Deposition (PVD) coatings show proven functionality, both in increasing the performance of cutting tools used to machine gears as well as in imparting beneficial layers on the gear itself. In both applications, the coatings improve tribological response of the cutting tool or gear, although the wear environments are quite different. The continuing […]

Direct Gear Design Drives Performance

On custom jobs, consider Direct Gear Design—an application-driven gear development process with primary emphasis on performance maximization and cost efficiency.

Modern gear design based on the gear rack generating process was introduced in the 19th century and remains the only way to design gears today. It considers the gear rack profile as the cutting edge of the tool. In order to define the gear geometry, the designer must select the generating rack parameters such as […]

Terry McDonald: Site Safety

Gear-machine manufacturers should place more emphasis on their equipment’s safety features as selling points, according to our monthly columnist.

Did you attend Gear Expo 2003 in beautiful downtown Columbus last October? It certainly was a show worth attending. The booths I visited were all well-manned, and well-designed to attract attention. The stories I heard from the exhibitors were that, while the number of attendees was down, the people that attended were the right ones, […]

Tooth Tips: Donald R. McVittie P.E.

Information you can use to prevent problems and prolong gear life.

Here's a checklist for "walking around" inspections of operating gear drives. It's intended to help you keep track of the health of your drives and to avoid surprise shutdowns. No tools are required except your eyes, ears, nose, and a sense of touch. The idea is to pause long enough each time you pass an […]
