High Pressure Water Deburring

Friendly both to parts and the environment, this process is gaining momentum in the gear-manufacturing industry as its many benefits are discovered.

Increasingly, gear manufacturers and others are expected to deliver burr-free clean parts to the point of use. To meet this challenge, part manufacturers are turning to new technologies. Traditional mechanical and abrasive deburring methods include hand and/or robotic mechanical deburring with deburring tools and rotary brushes or vibratory finishing. Abrasive Flow Machining (AFM), Thermal Energy […]

Lubricant Contaminants Limit Gear Life

It’s been estimated that 82 percent of machine wear is particle-induced, pointing to the importance of purchasing quality lubricants and keeping them free of particulate matter.

Lubricant cleanliness refers to the absence of contamination.1 Microscopic particles are the most harmful form of contamination in lubricants. They can irreversibly damage gear and bearing surfaces, shorten the service life of equipment, and cause unexpected breakdowns.1-4 The concentration of particles in new “as supplied” drums of lubricant can differ by as much as a […]

Abrasiveness of Boron Carbide Coatings

Parameters such as coating thickness, counterpart tempering temperature, and coating asperity sharpness in particular influence coating abrasiveness.

Hard coatings, such as boron carbide (B4C), can quickly polish the surface of the mating material during sliding contact. The abrasiveness of such coatings directly relates to their ability to polish and sharply decreases as sliding progresses. The abrasiveness also strongly depends upon the sharpness of the individual coating asperities. Various parameters influence the rate […]

Quality Cleaning for Gearing Applications

Just as there are many different methods for cleaning gears, there are many considerations to be aware of as well. Read on for an in-depth description.

Gears are precision components that place great demands on cleaning. The cleaning industry offers various solutions in order to fulfil these demands both economically and ecologically. Contamination from the manufacturing process—chips and residues from machining media, for example—may result in excessive wear and functional impairment for gear wheels. The quality of subsequent manufacturing processes such […]

DEPARTMENTS

Terry McDonald: Site Safety

As entertaining as they may be, and indispensable at times, cell phones and personal music players present a new workplace distraction that needs to be addressed.

What constitutes a safety issue? Are they only those that are covered by OSHA? Are they only the issues that arise when one of our employees has been injured? Are they only the items you read about, or that companies that sell safety items promote? They are all of these and many more, as you […]

The importance of anticipating heat-treatment problems in advance to avoid part failure due to cracking down the road

Problems, and even failures, occurring from heat treatment are generally created by the stresses that are induced when phase transformations are taking place. During the transformation either thermal expansion or contraction can take place, which induces stress. Internal stresses can occur with through-hardened, carburized, or nitrided gears. Residual stresses are compressive on the surface and […]

Chris Chlon: Buy Laws

Buyers and sellers alike should perform complete and accurate due diligence in order to prevent the many potential problems that come with a "first serial number" order.

Purchasing machinery and equipment presents many challenges to both the buyer and the seller. These include scope of work, specifications, drawings, timing, cost, run-off, delivery, and acceptance. Occasionally an unexpected issue or challenge develops for both parties at the same time. For example, the buyer’s team sends out its requests for quotes to known and […]
