[Case Study] Cost Reduction through Tolerance Relaxation
Due to the relaxation of tolerances, polishing the inner diameter is no longer necessary, resulting in cost reduction!
During the processing of POM material products, there was a challenge where the tolerance for the inner diameter was strict in machining, and performing polishing resulted in higher unit costs. Therefore, since a shaft with a negative tolerance would be inserted, it was determined that the H7 tolerance was unnecessary, and the tolerance was relaxed to what could be achieved through cutting processing. As a result, polishing the inner diameter was no longer necessary, leading to a reduction in costs. Our company can propose VE (Value Engineering) ideas by providing information about the type of parts that will be inserted. 【Overview】 ■ Issues - The tolerance for the inner diameter is strict in machining, and polishing leads to higher unit costs. ■ Solution - Since a shaft with a negative tolerance will be inserted, it was determined that the H7 tolerance was unnecessary, and the tolerance was relaxed to what could be achieved through cutting processing. ■ Effect - Polishing the inner diameter was no longer necessary, resulting in cost reduction. *For more details, please refer to the PDF document or feel free to contact us.
