High-frequency hardening shaft keyway bottom surface laser hardening case study
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
