Custom Gear Manufacturing Case Study: Gears for Fluid Pumps

Custom Gear Manufacturing Case Study: Gears for Fluid Pumps

Supports strict dimensional control of chamfer shapes, tooth base shapes, and more.

This is a spur gear used for driving semiconductor manufacturing equipment. Due to the need for corrosion and rust prevention, electroless nickel plating was required, which necessitated strict dimensional control, including the shape of the chamfer and the shape of the tooth root. Through quality control systems during the processes and final inspections, along with our long track record in manufacturing pump gears, we have been able to ensure stable precision. In particular, since a high degree of variation in quality can impair the functionality of the gears as pumps, a balance of precision, quality, and price is essential, and we have received comprehensive satisfaction from our customers. By entrusting us with this project, we have been recognized for improving product stability, resolving assembly yield issues, and significantly enhancing work efficiency.

Custom Gear Manufacturing Case Study [Drive System for Medical Devices]

Custom Gear Manufacturing Case Study [Drive System for Medical Devices]

Improvement of noise issues through optimization of the tool for treatment.

This is a gear for table rotation of a scientific analysis device. Due to the thin-walled and easily distorted shape of the product, the difficulty of production was high, and there were no manufacturers capable of producing it, leading to an inquiry to our company. By utilizing the know-how we have accumulated in the manufacturing of small-shaped gears, we implemented changes to lightweight jigs, managed tightening torque, and optimized hob coating, achieving stable processing including the spline section. Under the condition of finishing with gear cutting, we were able to significantly improve to JIS Class 1 standards in terms of noise and vibration. The noise issue often arises from shape changes due to distortion, but by producing stable products, we were able to meet the specified noise levels.

Custom Gear Production Case Study [Gears for Position Detection Devices]

Custom Gear Production Case Study [Gears for Position Detection Devices]

Significantly improved accuracy as a sensor!

This is a sensor ring gear used for position detection of the rotating shaft in machine tools. The indexing accuracy is of utmost importance for the gear that detects the indexing position of the spindle. If the indexing accuracy is poor, it will affect the machine's precision during indexing and consequently impact the accuracy of the processed workpiece. To improve accuracy, our company has applied the high-precision gear processing technology cultivated through worm machining, enabling us to achieve precision that cannot be addressed by conventional gear cutting processes. Based on our long-standing expertise in sensor processing, we are able to propose material changes and enhance the precision of blanks, thereby stabilizing the processing. Additionally, by improving the precision of the tools, we optimize the processing accuracy of the gears and achieve high precision. The impact of our high-precision hob machines is significant, allowing us to perform high-precision finishing processes that are difficult for other companies to replicate. Although the gears are challenging due to the need to ensure precision in cutting and finishing processes, we have significantly improved the accuracy as a sensor, enabling us to meet our customers' development needs.

Custom Gear Manufacturing Case Study: Drive System for Vehicle-Mounted Battery Manufacturing Equipment

Custom Gear Manufacturing Case Study: Drive System for Vehicle-Mounted Battery Manufacturing Equipment

Resolving issues with poor accuracy.

This is a spur gear for manufacturing equipment for vehicle batteries. We received feedback that its thin-walled design makes it difficult to achieve precision, resulting in unstable quality. The deformation during heat treatment is significant, making it challenging to maintain the product's shape, and further special surface treatments are required. Due to the importance of managing the film thickness, it was a product with difficult dimensional management. Many of our partner companies are manufacturers capable of handling special processing. By not only focusing on standard gear processing but also establishing a system to accommodate special processing, we have enhanced the product's completeness. For production, we implemented process design considering distortion, created fixtures that are resistant to distortion, and performed dimensional management taking surface treatment into account, which allowed us to stabilize product quality. With the stabilization of quality, adjustments during assembly became possible, resolving issues related to precision defects such as initial vibrations.

Custom Gear Production Example [Transmission Gear for Machine Tools]

Custom Gear Production Example [Transmission Gear for Machine Tools]

Developed a 3D chamfered shape to smooth out the gear change, which was a challenge for our customers.

This is a variable speed gear for the spindle of machine tools. The material is SCM, and it has undergone carburizing and quenching as heat treatment. We developed an original appropriate 3D chamfer shape to address the customer's issue of not being able to perform smooth gear changes during shifting. As a result of prototyping and verification, we eliminated damage to the chamfer contact area and the occurrence of burrs on the tooth surface, achieving smooth gear changes. Our company is capable of manufacturing gears that meet the specific requests from customers, as in this case. We conduct technical consultations and pursue the optimal gear together with our customers. For any inquiries regarding gears, please feel free to consult with OJIC.
