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

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

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

Ring guideway high-frequency hardening case study

Ring guideway high-frequency hardening case study

It is high-frequency hardening, an essential component for line equipment!

【Conventional Issues】 It was a high-frequency hardening project for the V-shaped surface of the ring's outer circumference with a short delivery time. However, due to the special shape of the hardened area, it was necessary to quickly manufacture a coil that matched the V shape. 【Response from Fuji High Frequency】 Since we manufacture coils in-house, we can produce coils and perform hardening within one and a half days. Additionally, using our long-standing expertise in bearing hardening, we can achieve low-distortion hardening through high-frequency moving hardening. 【Specifications】 Material: SUS440C Hardness: HRC55 Depth: 2.0mm or more Size: φ1109×24W

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

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

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
