長浜製作所 List of Products and Services

Our "Spin Test Service" is a service that actually spins rotating parts at high speeds to verify their "strength." We conduct experiments to determine how fast they can withstand and where their breaking limits are, evaluating safety and durability. We also analyze product shapes to ensure they reach the target rotational speed and provide design and manufacturing of attachments to achieve those goals. 【Spin Test】 ■ Overspeed Test: Strength Evaluation ■ Durability Test: Fatigue strength evaluation through repeated rotational profiles ■ Low Cycle Fatigue Test (LCF): S-N curve creation, creep property evaluation ■ Burst Test: Evaluation of failure conditions *For more details, please download the PDF or feel free to contact us.

We offer contract services for high-speed rotation and destruction testing using our high-speed rotation testing device "Centorio100." The maximum rotation speed is 240,000 rpm, and it can accommodate chamber temperatures up to 250°C. Testing is also possible under vacuum conditions (below 1 mbar) and high-temperature conditions. During the tests, we can accurately measure the points of plastic and elastic deformation, allowing for consistency evaluation with design calculations and analysis of failure behavior, resulting in high-precision data acquisition. Additionally, we capture the moment of failure with a high-speed camera and report waveform data and rotational behavior. The primary subjects of testing are motors and rotor components for electric vehicles, but the service can be applied across various industries, including metal materials, aerospace, and energy equipment. Facilities capable of actually "breaking" rotating bodies are limited in Japan, making this ideal for theoretical validation and safety design evaluation. *For more details, please download the PDF or feel free to contact us.*

Our company owns the high-performance testing device "Centorio 100," which can handle ultra-high-speed rotation tests of up to 240,000 rpm and high-precision evaluations in environments up to 250 °C. We conduct contract evaluations under various conditions, including verification tests for plastic and elastic deformation of electric vehicle (EV) motors, as well as destructive tests, durability tests, imbalance evaluations, and vacuum tests. We confirm the consistency between our customers' design calculations and actual measured behaviors, supporting the improvement of reliability.

In the machine tool industry, there is a demand for increasing the speed of rotating bodies such as spindles to shorten processing time and improve productivity. It is important to accurately understand the behavior of components under high-speed rotation and to verify the validity of the design. The Centrio 100 supports ultra-high-speed rotation testing of up to 240,000 rpm, helping to improve the reliability of high-speed machine tools by confirming the consistency between customers' design calculations and actual measured behavior. 【Application Scenarios】 * Durability evaluation of high-speed rotating machine tool components * Verification of vibration and deformation behavior of rotating bodies due to design changes * Assessment of the impact of imbalance during high-speed rotation 【Benefits of Implementation】 * Improved reliability of components under high-speed rotation * Early detection of issues during the design phase * Reduction of product development time
