Case of laser hardening of spiral bevel gear tooth surfaces.

Case of laser hardening of spiral bevel gear tooth surfaces.

Complex shapes are the specialty of laser hardening!

【Conventional Issues】 When performing high-frequency hardening, a dedicated coil tailored to the shape of the tooth is required. However, it is not feasible to incur the cost of creating an expensive dedicated coil for a single item that only flows a few pieces per year. 【Advantages of Laser Hardening】 With laser hardening, heating can occur as long as the laser beam is focused on the desired area, eliminating the need for the dedicated coil that is essential in high-frequency hardening. Additionally, there is less deformation after heat treatment, and hardening can be performed only on the necessary parts. 【Specifications】 Dimensions: Φ336×T190 Material: SCM435 Hardness: HRC57 Depth: 0.5mm

Thin Meat Plate Cam Laser Hardening Case Study

Thin Meat Plate Cam Laser Hardening Case Study

Even with thin workpieces, laser hardening is fine!

【Conventional Problems】 In high-frequency hardening, when heating the cam section, unnecessary parts of the workpiece are also affected by heat, resulting in significant deformation after heat treatment, making it unusable as a component. 【Benefits of Laser Hardening】 With laser hardening, it is possible to heat only the sliding surface of the cam, resulting in extremely small deformation after heat treatment, which can lead to reduced processing time and steps in subsequent processes. 【Specifications】 Dimensions: Φ247×Φ237×T10 Material: SUJ2 Hardness: HRC63 Depth: 0.5mm

Case study of φ600 mold inner diameter laser hardening

Case study of φ600 mold inner diameter laser hardening

Laser hardening is a processing method that has minimal distortion even when split in half!

【Conventional Issues】 Due to the fact that the mold is ultimately split in half, there was a possibility of significant distortion occurring when splitting it after high-frequency hardening. Therefore, a heat treatment method with minimal distortion was necessary. 【Advantages of Laser Hardening】 In laser hardening, hardening is performed in a striped pattern with a hardened width of about 25mm, which divides the hardened areas into individual lines, allowing the stresses from hardening to be distributed overall and reducing distortion. 【Specifications】 Dimensions: L1030×H800×T550 Material: SCM440 Hardness: HRC60 Depth: 1.0mm

Case study of high-frequency hardening of intermediate joints.

Case study of high-frequency hardening of intermediate joints.

It is a combined heat treatment of high frequency and laser!

【Conventional Issues】 More than 90% of the areas that require hardening have chosen high-frequency quenching, but a soft zone of about 10mm inevitably occurs at joints like R. Leaving the soft zone as is may affect the product's lifespan. 【Response from Fuji High Frequency】 The area where the soft zone of about 10mm occurred was hardened using laser quenching. As a result, the risk of quality defects due to the influence of the soft zone in this product has been improved. 【Specifications】 Dimensions: φ540×1960 Material: SCMN439 Hardness: Hs60 Depth: 1.8mm

Laser hardening of the hole section of the stop plate - case study

Laser hardening of the hole section of the stop plate - case study

Reduces distortion after heat treatment with laser hardening!

【Conventional Issues】 I want to harden only the groove on the outer circumference, but with conventional heat treatment, it is difficult to harden only the necessary parts, so I had no choice but to perform a full hardening. In that case, the distortion after heat treatment was significant, which was very problematic. 【Advantages of Laser Hardening】 Since it is possible to target only the areas that need to be hardened, unnecessary heat-affected zones can be eliminated, and the distortion after heat treatment can be minimized. 【Specifications】 Dimensions: Φ247×Φ237×T10 Material: SCM440 Hardness: HRC60 Depth: 0.7mm

M1 Gear One Tooth One Shot Laser Hardening Case Study

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

Case study of laser hardening of fan-shaped plates

Case study of laser hardening of fan-shaped plates

The iron fan will be laser hardened with "crack avoidance" and "distortion reduction"!

【Conventional Issues】 When hardening fan-shaped plates with high-frequency hardening, there are two main concerns: (1) There is a possibility of cracks occurring in the large holes near the outer diameter. (2) It is difficult to remove distortion. 【Advantages of Laser Hardening】 With laser hardening, there is no risk of cracks forming near the holes close to the outer diameter due to self-cooling. Additionally, by hardening both sides evenly, distortion can be reduced to less than 0.1mm. 【Specifications】 Dimensions: R405×W275×T25 Material: S45C Depth: 0.5mm or more Hardness: HRC52 or more
