M1 Gear One Tooth One Shot Laser Hardening Case Study

M1 Gear One Tooth One Shot Laser Hardening Case Study

We carefully handle each small "tooth" one by one!

【Conventional Issues】 - Due to the thin wall (thickness: 6mm), the entire workpiece becomes distorted at high frequencies and is unusable. - Because the module is small (M1), it was not possible to suppress distortion with single tooth hardening. 【Advantages of Laser Hardening】 - Localized heating and cooling allows for low-distortion hardening even for thin-walled products. - The ability to precisely target the required hardening area enables single tooth hardening for M1. 【Specifications】 Material: S45C Depth: At least two-thirds of the tooth height Hardness: HRC 55 or higher

Case study of laser hardening of fan-shaped plates

Case study of laser hardening of fan-shaped plates

The iron fan will be laser hardened with "crack avoidance" and "distortion reduction"!

【Conventional Issues】 When hardening fan-shaped plates with high-frequency hardening, there are two main concerns: (1) There is a possibility of cracks occurring in the large holes near the outer diameter. (2) It is difficult to remove distortion. 【Advantages of Laser Hardening】 With laser hardening, there is no risk of cracks forming near the holes close to the outer diameter due to self-cooling. Additionally, by hardening both sides evenly, distortion can be reduced to less than 0.1mm. 【Specifications】 Dimensions: R405×W275×T25 Material: S45C Depth: 0.5mm or more Hardness: HRC52 or more

100mm wide laser hardening case study

100mm wide laser hardening case study

Cost reduction with 100mm wide laser hardening! Shortened delivery time!

【Conventional Issues】 One of the disadvantages of laser hardening is that it cannot perform hardening over a wide width, requiring multiple lines to be scanned for hardening a large area, which has been a factor in increasing the cost of laser hardening. 【Advantages of Laser Hardening】 By utilizing a 12KW semiconductor laser and an optical system with a maximum width of 100mm (introduced in March 2020), it has become possible to perform laser hardening with a width of 100mm. Therefore, this leads to a reduction in the cost of laser hardening and a shortening of delivery times. 【Specifications】 Material: S45C Hardening layer depth: 0.86mm

High-frequency hardening shaft keyway bottom surface laser hardening case study

High-frequency hardening shaft keyway bottom surface laser hardening case study

Covering the weaknesses of high frequency with laser hardening!

【Conventional Issues】 The outer circumference of the shaft was subjected to high-frequency hardening, but to prevent cracking, the keyway area was thermally relieved with a copper jig and not hardened. However, according to product specifications, hardening of the bottom of the keyway was also necessary. 【Advantages of Laser Hardening】 The outer circumference of the shaft undergoes hardening over a larger area, making high-frequency hardening more cost-effective. Therefore, high-frequency hardening was chosen, while laser hardening is considered safer for the bottom of the keyway. 【Specifications】 Dimensions: φ80×1229 Material: S45C Depth: 0.5–1.0mm Hardness: Hs70 or higher

Laser hardening of roller sliding surfaces case study

Laser hardening of roller sliding surfaces case study

No coil needed, significant cost reduction with laser hardening!

【Conventional Issues】 This product is designed for small-batch production with a variety of types, and the hardened surface has an R shape, which typically requires the fabrication of coils for standard high-frequency hardening. (Fabrication cost: 100,000 yen; Fabrication time: 3 days) 【Advantages of Laser Hardening】 By switching to laser hardening, the need for coil fabrication is eliminated even in small-batch production, resulting in reduced fabrication costs and time. As a result, the manufacturing cost of the components has significantly decreased. 【Specifications】 Material: S45C Depth: 0.5mm or more Hardness: HRC58-60

Case study of laser hardening for small punch molds

Case study of laser hardening for small punch molds

Same-day delivery available! Improved durability with laser hardening!

【Conventional Issues】 Traditionally, vacuum hardening was performed using SKD11 (approximately 500 yen/kg), which took a minimum of one day. 【Advantages of Laser Hardening】 In the case of laser hardening, it is possible to switch to S45C (approximately 150 yen/kg), achieving a reduction in material costs and a shorter delivery time (about 10 minutes). 【Specifications】 Dimensions: W30×L50×T15 Material: S45C Depth: 0.5–1.0mm Hardness: HRC60

Thin Meat Roller Laser Hardening Case Study

Thin Meat Roller Laser Hardening Case Study

Solve the soft zone problem with laser hardening!

【Conventional Issues】 In high-frequency induction hardening, the soft zone forms a triangular shape (red dashed line) and reaches approximately 30mm at its widest point. As a result, the durability at the position of the soft zone decreases. Additionally, distortion in thin sections is also a concern. 【Advantages of Laser Hardening】 In laser hardening, the soft zone is reduced to 1.5mm, resolving issues related to abnormal wear in the soft zone. Furthermore, distortion in thin sections is limited to within 0.1mm. 【Specifications】 Material: SCM435 Depth: 0.3–0.5mm Hardness: HRC55

Scroll cam laser hardening case study

Scroll cam laser hardening case study

A combination of nitriding and laser hardening!

【Conventional Issues】 Previously, nitriding was performed on the cam surface, but the nitrided layer would quickly wear away in areas that were prone to load, leading to localized abnormal wear and a shorter lifespan. 【Benefits of Laser Hardening】 By performing laser hardening only on the areas with severe wear, the hardened layer becomes deeper (approximately 0.5mm), which helps to suppress the occurrence of abnormal wear and contributes to an increase in product lifespan. 【Specifications】 Dimensions: φ56 L=1054 Material: S45C Depth: 0.5mm Hardness: HRC60

Case study of complex shape block laser hardening

Case study of complex shape block laser hardening

Even complex shapes can be achieved with laser hardening!

【Conventional Issues】 There are three hardening surfaces on a single block, and they are very close to each other. As a result, during high-frequency hardening, the heat impact from hardening (2) and (3) after hardening (1) causes (1) to be tempered. 【Advantages of Laser Hardening】 Laser hardening is characterized by its ability to perform pinpoint hardening, which minimizes the thermal impact on the surrounding areas at each location. Therefore, there is no risk of tempering. 【Specifications】 Material: S45C Depth: 0.4–0.8mm Hardness: HRC55–57

Case of Axis Rotation Laser Hardening

Case of Axis Rotation Laser Hardening

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

【Conventional Issues】 In conventional high-frequency hardening, there were three challenges: (1) the risk of cracks, (2) the narrowing of the key groove width, and (3) the hardening of the screw section. As a result, extra material had to be removed, leading to increased costs in post-processing. 【Advantages of Laser Hardening】 By adopting laser hardening, which allows for precise hardening of only the targeted areas, the issues (1) to (3) were resolved, resulting in a reduction in post-processing costs after hardening. 【Specifications】 Dimensions: φ30×L538 Material: S45C Depth: 0.3–0.8mm Hardness: HRC55 or higher

Main Axis Laser Hardening Case Study

Main Axis Laser Hardening Case Study

Even with holes and grooves, laser hardening can prevent cracks!

【Conventional Issues】 Hardening of the sides and end faces is necessary, but due to the numerous hole and groove machining in the areas that require hardening, the difficulty of hardening increases with high-frequency quenching, raising the risk of cracking. 【Advantages of Laser Hardening】 With laser hardening, the grooves can be hardened by allowing light to escape, eliminating the risk of cracking. Additionally, for the holes, there is no edge effect like with high-frequency, so there is no risk of overheating. 【Specifications】 Dimensions: φ280×L780 Material: SCM440 Depth: 1.0–1.5mm Hardness: HRC50–56
