Covering the weaknesses of high frequency with laser hardening!
【Conventional Issues】 The outer circumference of the shaft was subjected to high-frequency hardening, but to prevent cracking, the keyway area was thermally relieved with a copper jig and not hardened. However, according to product specifications, hardening of the bottom of the keyway was also necessary. 【Advantages of Laser Hardening】 The outer circumference of the shaft undergoes hardening over a larger area, making high-frequency hardening more cost-effective. Therefore, high-frequency hardening was chosen, while laser hardening is considered safer for the bottom of the keyway. 【Specifications】 Dimensions: φ80×1229 Material: S45C Depth: 0.5–1.0mm Hardness: Hs70 or higher

Company information
Fujikou Shuhou Industry Co., Ltd. was established in 1958 in Sakai City, Osaka Prefecture, starting with the heat treatment of large bearings. Since then, we have expanded our operations to cover a wide range of industrial machine parts. In December 2008, we began contract processing for laser heat treatment, and in January 2012, we quickly took on laser cladding, continuing to this day. Our expertise in partial heat treatment of metal components spans from large items to precision parts. We have also obtained ISO 9001 certification and have become a certified factory in various industries, continuously striving for improvement in technology and skills through relentless effort and a spirit of reform. As a result, we have earned the trust of our customers across various industries with our high quality and technical capabilities. Moving forward, we aim to accurately respond to the diversifying and advancing needs of our customers, and with our two pillars of high-frequency heat treatment and laser heat treatment, we aspire to contribute, even in a small way, to the advancement of Japanese manufacturing, working together as a unified company.
