Case study of rack gear high-frequency hardening

We can perform high-frequency hardening of super-large rack gears!

【Conventional Issues】 High-frequency hardening of large rack gears is difficult to address without the technology for hardening one tooth at a time. Additionally, distortion occurs after high-frequency hardening, so technology for distortion correction is also necessary. 【Response from Fuji High Frequency】 Our company specializes in hardening one tooth at a time, and we can apply this technology to perform high-frequency hardening of large rack gears. Furthermore, we also correct for distortion, ensuring that the final product is shipped with a total length distortion of within 0.1mm. 【Specifications】 Material: S45C Hardness: HRC58 Depth: 2.0mm

Case study of high-frequency quenching with gripper pit.

The jagged parts will be hardened with high-frequency quenching!

【Conventional Issues】 The gripper pit is a fixture for gripping large steel pipes. I want to harden the serrated part that grips the steel pipe, but there are thin sections that pose a high risk of cracking. 【Response from Fuji High Frequency】 Regarding the serrated part that grips, it is necessary to achieve both a hardened layer depth of over 2mm and hardness, so air cooling during high-frequency quenching was chosen. This way, the risk of cracking can also be avoided. 【Specifications】 Material: SNCM439 Hardness: Hs70 Depth: 2mm

M10 Gear Tooth Surface Laser Hardening Case Study

Reduce construction time and costs with laser hardening!

【Conventional Issues】 The final precision required for the gears is not that high, but if high-frequency hardening or carburizing is performed, the precision of the gears deteriorates, necessitating a gear grinding process. 【Advantages of Laser Hardening】 By finishing to the required precision during the gear cutting process and making laser hardening the final step, the degradation of tooth precision has been minimized. As a result, the gear grinding process has been eliminated, leading to reductions in both construction time and costs. 【Specifications】 Dimensions: Φ227×145mm Material: SCM440 Hardness: HRC55 Depth: 0.5mm

Large Ring Groove High-Frequency Hardening Case Study

With over 60 years of expertise in high-frequency hardening, we can also handle the production of difficult coils!

【Background】 Partially high-frequency hardening of the inner diameter of large rings is challenging due to the difficulty in manufacturing coils. As a result, there are only a limited number of processing companies capable of handling such projects. 【Response from Fuji High Frequency】 Utilizing over 60 years of expertise in high-frequency hardening, we carry out optimal hardening methods and coil manufacturing. For this project, we determined that cooling with air, which poses minimal risk, is the best approach. 【Specifications】 Dimensions: φ1220×φ1037×238W Material: SCM440 Hardness: HRC50 Depth: 2mm

Case of laser hardening of the shaft part of the whetstone platform.

Combining toughness and wear resistance!

【Conventional Issues】 In high-frequency hardening, the shaft diameter becomes φ6, resulting in hardening all the way to the interior, which poses a toughness issue as it can break under impact. However, the surface of the shaft wears out, so it was desired to harden it. 【Advantages of Laser Hardening】 With laser hardening, only the surface of the φ6 shaft was hardened to a depth of 0.3mm. By not hardening the interior, both toughness and surface wear resistance characteristics were achieved. 【Specifications】 Dimensions: φ6×59.5mm Material: SCM435 Hardness: HRC51 or higher Depth: 0.3mm

Attention those troubled by distortion during heat treatment! A new heat treatment method that can also handle thin materials.

Reduce distortion by 50% with the conventional quenching method! A new surface hardening heat treatment method, "Nitriding Quenching," that does not warp even with thin materials. *Prototyping and test processing available.

Aitec's "Nitriding Quenching" is a new surface hardening heat treatment method that allows nitrogen to permeate and diffuse into steel, followed by quenching from the austenite state. By introducing nitrogen and performing quenching, a surface hardness of about 850 HV can be achieved even with inexpensive SPCC material, and it is possible to increase hardness within the range where nitrogen has diffused internally! ~ Currently recruiting for prototype and test processing! ~ 【Benefits of Nitriding Quenching】 ■ Useful as an alternative surface hardening method for components ■ Effective for components that require low distortion ■ Capable of hardening throughout the interior ■ Achieves a deeper hardened layer in a shorter time than gas soft nitriding treatment *For details, please refer to the PDF available for download below or feel free to contact us.

Zero CO2 Emissions: New Heat Treatment Method 'Nitriding Quenching' with Minimal Distortion Even for Thin Materials

A new heat treatment method that contributes to "reduced environmental impact" and "low distortion" compared to conventional carburizing quenching! Zero CO2 emissions with ammonia quenching.

Aitec's "Nitriding Hardening" is a surface hardening heat treatment method characterized by low distortion, which involves the infiltration and diffusion of nitrogen into steel and quenching from the austenite state. This heat treatment method allows nitrogen to infiltrate and dissolve in the austenite region (γ) of the Fe-N2 binary phase diagram. It then rapidly cools to produce hard nitrogen martensite. Unlike conventional "carburizing hardening," this process uses ammonia for quenching, resulting in zero CO2 emissions during the treatment process! It can be proposed as a new treatment method that considers environmental impact. **Benefits of Nitriding Hardening** ★ No CO2 emissions from quenching with ammonia - High surface hardness of HMV800 or more even with SPCC material - Lower quenching temperature than carburizing, resulting in low distortion (with a proven example of 50% reduction in distortion) - High resistance to softening - Total cost reduction without distortion correction ~ "Decarbonized Heat Treatment Nitriding Hardening Seminar" Video Now Available for Free! ~ ◆ Theme: Decarbonized Heat Treatment Nitriding Hardening Seminar Exploring the Possibilities from Carburizing to Nitriding ◆ Available Video: Nitriding Hardening Mass Production & Development Cases ◆ How to View: From the YouTube link at the bottom of this page *For more detailed information, please refer to the technical materials available for download in the [PDF Download] section below.

High surface pressure resistance technology "KHD treatment"

Vacuum hardening that improves the durability of molds and tools by more than three times! Introduction of our uniquely developed technology.

We would like to introduce KHD processing, a unique development technology by Kuniyu Thermal Engineering. From the perspectives of weight reduction for improved fuel efficiency and enhanced safety, the introduction of high-strength steel materials is increasing. However, these materials are difficult to process, leading to significant wear on molds and tools, which necessitates improvements in strength and durability. Our development technology applies vacuum carburizing treatment to these tools, achieving excellent surface modification treatment for high surface pressure wear resistance, thereby extending the "lifespan" of molds and tools. This results in cost reduction through decreased frequency of mold replacements and improved productivity, while also addressing the anticipated "further adaptation to higher strength steel materials" in the future. [Key Points] ■ Hard coating with high resistance to high surface pressure → Generates a hard coating on the surface of the component with a hardness of approximately Hv3,000 (Hv = Vickers hardness) - Result: Wear resistance to high surface pressure is enhanced by more than twice ■ High adhesion "non-peeling coating" → Creates a "substrate gradient reinforcement layer" with a gradient hardness distribution into the base material - Result: Achieves three times the adhesion of conventional coatings with a "non-peeling coating" *For more details, please refer to the PDF document or feel free to contact us.
