Ring gear laser hardening case study

Ring gear laser hardening case study

Laser hardening can achieve low cost and shortened construction time with reduced distortion!

【Conventional Issues】 With conventional high-frequency hardening, while the heat treatment cost is reduced, the thermal impact becomes significant, causing distortion in the inner diameter, which necessitates secondary processing (finishing). 【Advantages of Laser Hardening】 With laser hardening, the heat treatment cost has become “one-shot hardening < laser hardening,” and since secondary processing of the inner diameter can be reduced, the overall cost is lower and the project timeline is shortened with laser hardening. 【Specifications】 Dimensions: φ596×22W×M4×147T Material: S45C Depth: 0.5mm Hardness: HRC57 or higher

Case study of laser hardening on knurled surfaces.

Case study of laser hardening on knurled surfaces.

You can perform laser hardening on jagged surfaces too!

【Conventional Issues】 I wanted to harden only the tip of the knurl, but with high-frequency hardening, the entire surface becomes hardened, causing overall distortion. Additionally, due to processing considerations, areas with thinner wall thickness are at risk of melting due to edge effects. 【Advantages of Laser Hardening】 By hardening only the tip that comes into contact with the counterpart, distortion caused by heat treatment was minimized. Furthermore, with laser hardening, distortion correction hardening can be performed on the backside, further reducing distortion. 【Specifications】 Material: S45C Hardness: HRC 55-57 Depth: 0.5-0.8 mm

Case study of laser hardening of convex end surfaces.

We will harden only the small protrusions with laser hardening!

【Conventional Issues】 With high-frequency hardening, it is difficult to harden only the edge surface of the protruding part without affecting other areas with heat. The heat influence on other parts can lead to distortion, making post-processing likely necessary. 【Advantages of Laser Hardening】 With laser hardening, it is possible to precisely target and harden only the edge surface of the protruding part. Since there was almost no heat influence on unnecessary areas, there were no issues with distortion after heat treatment. 【Specifications】 Material: S45C Hardness: HRC 45 or higher Depth: 0.7mm

Case study of laser hardening of rail with small diameter holes.

Avoid the risk of cracking during grilling in thin meat sections with laser hardening!

【Conventional Issues】 In high-frequency hardening, there is a high risk of cracking in the areas directly beneath the hardened surface (thin sections). Additionally, the thin sections may become overly hardened, increasing the likelihood of cracks during distortion correction. 【Advantages of Laser Hardening】 With laser hardening, it is possible to achieve a hardening depth of 0.6mm, which allows for the avoidance of cracking risks even in thin sections. Furthermore, since the hole areas do not become overly hardened, distortion correction becomes easier. 【Specifications】 Dimensions: 32w × 318L × 9t Material: S45C Hardness: HRC58 Depth: 0.6mm

Case study of thin-walled hollow bolt spiral laser hardening

Case study of thin-walled hollow bolt spiral laser hardening

Do you know about the laser hardening method called "spiral hardening"?

【Conventional Issues】 Due to the thin thickness of approximately 6mm in the hardening area, there are concerns about deformation after heat treatment with high-frequency hardening. Additionally, the threaded section at the tip of the shaft should not be hardened, but hardening is desired up to the vicinity of the threaded area. 【Benefits of Laser Hardening】 By performing hardening in a spiral pattern, it is possible to disperse the stresses caused by hardening and reduce deformation after heat treatment. Furthermore, the hardened areas bulge a few micrometers above the work surface, exhibiting effects similar to full hardening in terms of wear resistance due to surface contact. 【Specifications】 Material: SCM435 Hardness: HRC50 Depth: 0.4mm

Large Tapered Roll Laser Hardening Case Study

Large Tapered Roll Laser Hardening Case Study

Solve the weaknesses of high-frequency hardening with laser hardening!

【Conventional Issues】 In high-frequency hardening, the difference between the maximum and minimum diameters of the tapered section is large, resulting in a variation in the distance from the coil to the workpiece, making it difficult to heat and cool evenly. This leads to variability in hardness and hardening depth. 【Advantages of Laser Hardening】 In laser hardening, a constant focal distance is maintained through robot teaching, allowing for uniform heating of the heated area. Additionally, since laser hardening does not require cooling water (self-cooling), the hardness and hardening depth can be kept consistent. 【Specifications】 Dimensions: Φ235×L2151 Material: SCM440 Hardness: HRC60 Depth: 0.7mm

Case study of small holder laser hardening

Case study of small holder laser hardening

If it's laser hardening, we can accommodate short delivery times without "coils"!

【Conventional Issues】 I want to partially harden the R surface of the holder. Additionally, I would like the processing to be done in the shortest possible time. However, due to the need for coils in high-frequency hardening, it is difficult to accommodate short lead times, and there is a risk of cracking near the holes. 【Advantages of Laser Hardening】 With laser hardening, there is no need to manufacture coils, allowing processing to begin immediately after the workpiece arrives. Furthermore, because the hardened layer is shallow, hardening can be performed without the risk of cracking in thin sections or near holes. 【Specifications】 Dimensions: L60×H30×T18 Material: S45C Hardness: HRC58 Depth: 0.5mm

M2 Rack Gear Laser Hardening Case Study

M2 Rack Gear Laser Hardening Case Study

Easily distorted gears are solved with laser hardening!

【Conventional Issues】 When hardening is performed using high-frequency hardening, it is not possible to harden just one tooth, and the base of the tooth becomes hardened. As a result, cracks occur at the hardened base of the tooth during distortion correction. 【Benefits of Laser Hardening】 With laser hardening, it is possible to target only the surface of the tooth for hardening, which can reduce distortion after heat treatment. Additionally, since the base of the tooth does not harden, cracks at the base can be avoided during distortion correction. 【Specifications】 Dimensions: L1330×H13×T114 Material: SCM440 Hardness: HRC60 Depth: 0.3mm

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

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

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
