We would like to introduce a case where we proposed to "improve the processing efficiency of development parts in the prototype stage." Our customer was struggling to find an efficient processing method for long-axis parts in the development prototype stage. The structure involved a product that welds three parts together. We proposed changing the structure so that the three parts fit together in the previous process while maintaining strength. By reducing the angle of the welding groove, we were able to decrease the amount of welding rod needed, achieving a cost reduction of one-third. 【Case Overview】 ■Challenge - Is there an efficient processing method for long-axis parts in the development prototype stage? ■Result - By adopting a fitting structure, we simplified the positioning during welding, which also led to a reduction in process time. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case study of our proposal for "eliminating polishing of heat-treated parts." The customer was troubled and consulted us because their usual subcontractor, who they always request for cylindrical and flat polishing, was busy and unable to take on the job. At our company, we can perform cylindrical and flat polishing in collaboration with our subcontractors. Upon reviewing the drawings, we thought, "There are polishing instructions, but isn't it possible to achieve the required precision without polishing?" and proposed a polishing-free solution. 【Case Overview】 ■ Issues - No polishing machine available, and the subcontractor is overwhelmed with capacity and unable to accept requests. ■ Proposal - We have been continuously accumulating data on vacuum hardening and high-frequency hardening, and from our experience, we can confirm that polishing-free solutions are possible with a precision of approximately ±0.05mm. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we proposed "local production of overseas parts that were being procured." The customer was struggling with the long procurement and repair times for the overseas parts they were using. We conducted shape measurements, material investigations, and hardness tests on the overseas parts. Based on the results, we proposed a manufacturing method and were able to achieve local production. [Case Overview] ■ Challenges - The overseas parts being used took a long time to procure and repair. ■ Results - We were able to handle everything from procurement to repair, achieving a three-month reduction in delivery time and cost savings. - Quality improved, resulting in better cost performance. *For more details, please refer to the related links or feel free to contact us.
