Case study of high-frequency hardening of L-shaped plates.

Case study of high-frequency hardening of L-shaped plates.

Achieve short delivery times with a high-frequency oscillator featuring special coils and high-capacity output!

【Conventional Issues】 For L-shaped plates with a wide specified hardening width, special coils and high-frequency oscillators with large output capacity are required. Additionally, due to the large area of the L-shape, laser hardening cannot be performed without soft zones. 【Response from Fuji High Frequency】 We have an advantage in terms of delivery time and cost because we manufacture high-frequency hardening coils in-house. Furthermore, we possess high-frequency oscillators with a maximum output of 600KW, allowing us to perform hardening over such large areas without soft zones. 【Specifications】 Material: S45C Hardness: HRC58 Depth: 2.0mm

Case study of rack gear high-frequency hardening

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.

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

Large Ring Groove High-Frequency Hardening Case Study

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

High-frequency hardening

High-frequency hardening

Widely adopted as a method to enhance the properties of metallic materials possessed by each component mechanically!

We would like to introduce our "high-frequency hardening" process. Devices and equipment collectively referred to as machinery, including automobiles, exhibit their intended functions through the forces and actions transmitted from the power unit via each of their components. High-frequency hardening is a widely adopted method for enhancing the mechanical properties by drawing out the characteristics of the metal materials possessed by these components. 【High-Frequency Hardening Process】 ■ One-shot hardening of inner diameters ■ One-shot injection hardening with workpiece rotation ■ Moving hardening *For more details, please refer to the PDF materials or feel free to contact us.

Screw Strengthening Manual (Vol. 41) Sometimes it can be partially hardened!

Screw Strengthening Manual (Vol. 41) Sometimes it can be partially hardened!

Introducing a method to heat only the surface of materials that can be hardened, in a blog format!

This time, I will talk about high-frequency hardening. It is a heat treatment method where a copper wire coil, called a high-frequency coil, is wrapped around a product that you want to harden, and heat is applied by passing an electric current to harden only the surface. While one might think that general heat treatments like quenching or annealing would suffice for hardening, there are valid reasons for choosing high-frequency hardening. *For more detailed content, you can view it through the related links. Please feel free to contact us for more information.*

Metal Heat Treatment Guide: What is High-Frequency Quenching?

Metal Heat Treatment Guide: What is High-Frequency Quenching?

A suitable method for steel with a carbon content of 0.3% or more! Introduction to the basics of heat treatment.

"High-frequency quenching" is a heat treatment method that induces electromagnetic induction in metals using high-frequency electromagnetic waves, overheating the surface to perform quenching. This process hardens only the surface of the metal, increasing its hardness while maintaining the original state of toughness in the interior, allowing for the creation of materials rich in flexibility. Depending on the type of steel, the surface hardness generally increases by about 1 to 2 Rockwell hardness (HRC) compared to conventional quenching. 【What is high-frequency quenching】 - It is possible to create materials rich in flexibility by hardening only the surface of the metal to increase hardness while maintaining the original state of toughness in the interior. - The surface hardness generally increases by about 1 to 2 Rockwell hardness compared to conventional quenching. - This method is mainly suitable for steel with a carbon content of 0.3% or more. *For more details, please refer to the PDF document or feel free to contact us.
