Case study of high-frequency hardening of large shafts.

We have a high-frequency oscillator with high output capacity, so large-sized workpieces can also be subjected to high-frequency hardening!

【Background】 To perform induction hardening on a shaft with an outer diameter of φ940, a high-frequency oscillator with a large output capacity is necessary. This limits the number of companies capable of doing so even within the country. 【Response from Fuji High Frequency】 Using a large high-frequency oscillator of 6KHz×600KW makes it possible to perform induction hardening on large shafts with an outer diameter of φ940. Additionally, since a deep hardened layer is required, the frequency of 6KHz becomes important. 【Specifications】 Dimensions: φ940×850L Material: S45C Hardness: HRC58 Depth: 5mm

Case Studies on Solving Laser Hardening Issues

Explaining with points! Introducing our initiatives based on actual case studies of problem-solving that have occurred.

This document is a collection of case studies summarizing solutions to challenges in laser hardening. It explains how issues that were problematic with conventional heat treatment were resolved through laser hardening, highlighting key points. Based on actual examples of problem-solving, such as "high-frequency hardening of the inner diameter" and "soft zone filling with laser," we will introduce our efforts. We invite you to read it. 【Contents】 ■Introduction ■Case Studies of Problem Solving (1) to (5) ■Conclusion *For more details, please refer to the PDF document or feel free to contact us.

M1 Gear One Tooth One Shot Laser Hardening Case Study

We carefully handle each small "tooth" one by one!

【Conventional Issues】 - Due to the thin wall (thickness: 6mm), the entire workpiece becomes distorted at high frequencies and is unusable. - Because the module is small (M1), it was not possible to suppress distortion with single tooth hardening. 【Advantages of Laser Hardening】 - Localized heating and cooling allows for low-distortion hardening even for thin-walled products. - The ability to precisely target the required hardening area enables single tooth hardening for M1. 【Specifications】 Material: S45C Depth: At least two-thirds of the tooth height Hardness: HRC 55 or higher
