Optical Strain Measurement: What You Need to Know

Leave a Comment

Optical strain measurement is a non-contact measurement technique that employs digital image processing principles. Compared to traditional strain measurement methods, this technique provides a more streamlined solution for testing operations. The increase in testing efficiency is due largely to the elimination of the need for the modification of parts for lead-wire routing and sensor attachment.  […]

Industrial Applications of Spin-Testing and Balancing

Leave a Comment

Precision testing of high-speed, high-performance motors and rotors is of paramount importance in today’s aerospace, automotive, and defense industries.  Spin testing is performed to validate the design, durability, balance, and structural integrity of the motor. The material and structural behavior of the rotor, which ties to the efficiency of a machine, is of major import across the many varied applications […]

Test Devices Afterburner Small Jet Engine Test

Spin Testing Additively Manufactured or 3D-Printed Parts

Leave a Comment

Additive manufacturing (AM) is the process of building 3D workpieces layer by layer. Rather than traditional processes such as machining, which create forms by removing the material from stock material, additive manufacturing “prints” layers into a part from a computer model created with Computer Aided Design (CAD) software. The AM technique has been around for […]

Spin Testing for Manufacturing 101

Leave a Comment

In the quest to produce stronger, more durable, and cost effective rotating parts, manufacturers are turning to spin tests to help achieve these goals. Spin tests for manufacturers can be used to validate the stability and integrity of a part, or to enhance the desirable properties of the material. We will explore the differences between […]

Expanding Capacity – Balancing Services

Leave a Comment

Rotating components such as jet engine disks and high-speed motor armatures must be balanced well to warrant a good performance and overall longevity of machines. Balancing machines pinpoint the exact amount and the location of unbalance in rotating components. Once these areas are identified, skilled technicians correct the unbalance level by either removing material in […]

eDrive Trends and Growth Potential for 2019

Leave a Comment

In recent years, electric vehicles have made a big impact on the mainstream automotive market. Consumers in more and more parts of the country are switching to zero-emissions vehicles as the risks and results of unmitigated climate change become more pronounced. Therefore, many automotive manufacturers are beginning to design, build, and sell electric vehicles, contributing […]

Why You Should Invest in a Proof Test

Leave a Comment

Proof tests are special forms of validation tests that are intended to demonstrate the fitness of any given load-bearing root structure. In the case of spin testing, proof testing is typically performed in order to validate design requirements for certification, such as FAA or EASA for jet engines. It is also frequently used to screen for production quality in […]
