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.
