Do No Destructive Testing
by Jack McGuinn, Sr. Editor, Jan/Feb 2013, Gear Technology
The main safety practice in the big gear industry is “if it ain’t test, don’t use it.” Israel Vasquez, an independent quality systems and NDT level 3 consultant, compares the application of NDT on large gears materials, parts and components to examination procedures practiced by today’s medical practitioners (to not harm the patient). Vasquez says “the basic principles behind NDT are to examine materials, components and/or parts for characteristics (that are) detrimental to their use (i.e., defects), by methods that will not induce physical (and costly) changes (damage) to the item being inspected.”
Because bigger gears have bigger manufacturing costs, non-destructive testing makes perfect sense. After all, these outsized gears are often built to order, requiring only a few pieces, sometimes just one. The amount of testing required is based on economic risk factors. Parts used in critical applications, such as aerospace, aircraft, bridges and nuclear facilities require reliability. Testing required may include any or all of the following:
- Testing at Raw Material Source
- Testing of Manufacturing Process
- Initial Inspections during Installation
- Periodic Inspections (for service-induced defects)
NDT testing uses computer and digital radiography, magnetic particles inspection and ultrasonic inspection (UT). Selection and degree of testing is often negotiated during the contract arrangements. Typically, these gears need to pass inspections for hardness, burns, cracks, inclusions, porosity and discontinuity.

Gear Grinding gets Integrated at IMTS
by Matthew Jaster, September 10-15, 2012, Gear Technology
More than 100,000 visitors arrived at IMTS in Chicago from September 10–15, making it the strongest showing for the manufacturing technology trade show in over a decade. While many attendees and customers were looking for expert partners, some were acutely aware that they needed gear grinding capabilities that would improve grinding times without sacrificing gear quality. This meant customers were seeking Advanced Solutions.
Customers were also looking for technologically cutting edge solutions at a competitive price and process flexibility. Overall, the following features, capabilities and concepts were discussed during IMTS:
- Faster setup times
- Higher productivity
- Maximizing machine utilization
- Process flexibility
- Total cost ownership
