Case of high-frequency hardening of a single tooth of a helical gear.

Case of high-frequency hardening of a single tooth of a helical gear.

We can accommodate special shapes as we have a large number of coils!

【Conventional Issues】 We were requested to respond to a very short delivery time for high-frequency hardening of single-unit helical gears. Due to the nature of single-unit helical gears, it was necessary to manufacture coils urgently. 【Response from Fuji High Frequency】 We have thousands of types of coils tailored to various modules, and even if there is no coil that fits the shape, we can quickly make adjustments in-house. We were able to meet the delivery time within one and a half days. 【Specifications】 Dimensions: M18×80T×340W×φ1440 Material: SCM435 Depth: 2.0mm or more at PCD Hardness: Hs65–75

Case of high-frequency hardening of the bottom of Φ720 gear teeth in one shot.

Case of high-frequency hardening of the bottom of Φ720 gear teeth in one shot.

Powerful heat treatment! Instant high-frequency hardening!

【Conventional Issues】 Until now, due to the material being S45C, one-tooth induction hardening was performed, which took about 5 hours for high-frequency heat treatment. To reduce heat treatment costs, a change in material was proposed (S45C ⇒ SCM440). 【Response from Fuji High Frequency】 With our 600KW high-frequency oscillator, it is now possible to perform one-shot hardening down to the tooth base, reducing the heat treatment time from the conventional 5 hours to 0.5 hours, leading to a reduction in heat treatment costs. 【Specifications】 Dimensions: M12 × 60T × 250W × φ720 Material: SCM440 Hardness: Hs60–70

Spindle internal gear high-frequency hardening case study

Spindle internal gear high-frequency hardening case study

High-frequency hardening can be done with internal gears!

【Conventional Issues】 When carburizing and quenching, unnecessary parts become hard, making post-processing difficult. Additionally, even when selecting high-frequency single-shot quenching to reduce costs and lead times in heat treatment, significant distortion occurs. 【Response from Fuji High Frequency】 To address these issues, we performed surface hardening of one tooth of the internal gear. By not hardening unnecessary parts, post-processing became easier, and sufficient hardened layer depth was achieved. 【Specifications】 Dimensions: MP8×100W×385L Material: S45C Hardness: Hs65 Depth: Over 2mm

φ150 Shaft High-Frequency Hardening Case Study

φ150 Shaft High-Frequency Hardening Case Study

Our high-frequency hardening equipment can accommodate shafts up to 4 meters in length!

【Background】 In the high-frequency hardening of a large shaft with an outer diameter of φ150 and a length of L1700, there was a request for a hardened layer depth of 3mm and to minimize distortion as much as possible after hardening. 【Response from Fuji High Frequency】 By using our unique shaft hardening method and applying high-frequency hardening, we achieved both the occurrence of distortion and a deep hardened layer depth. Additionally, this equipment can accommodate vertical hardening up to 4m. 【Specifications】 Material: S45C Hardness: HRC58 Depth: 2mm Size: φ150×L1700

Case study of large lever high-frequency hardening

Case study of large lever high-frequency hardening

It is possible to perform high-frequency hardening on levers larger than those of a person!

【Background】 In partial quenching of large, specially shaped products, it is necessary to manufacture special-shaped coils to perform high-frequency treatment according to the drawings. Additionally, a large high-frequency quenching machine capable of handling this quenching is also required. 【Fujikou High Frequency's Response】 Our company manufactures coils in-house, so we can produce such special-shaped coils with short lead times and low costs. We also specialize in large products, and if the project can fit within our factory, we can almost always accommodate the quenching. 【Specifications】 Material: S45C Hardness: HRC58 Depth: 3mm

Case study of high-frequency hardening of large shafts.

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 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
