In precision machining, CNC machines are only part of the equation. Cutting tool is a key factor that directly affects accuracy, surface finish, and product stability.
At Yumoto Vietnam, the selection, use, and control of cutting tools are always regarded as critical steps in the production process.
At Yumoto Vietnam, the selection of cutting tools is not based solely on the tolerances specified in the drawings, but also on the engineers’ technical evaluation for each individual design.
Engineers consider factors such as part geometry, material, appearance requirements, and potential risks during the machining process in order to select the most suitable cutting tools. This approach enables Yumoto to control dimensional accuracy and machining quality from the very first stage, while also ensuring production stability.
In mass production, cutting tools must not only meet initial quality requirements but also maintain repeatability and stability throughout the entire machining process.
Yumoto places strong emphasis on:
These measures help reduce the risk of unexpected defects during production and ensure consistent quality across the entire batch of products.
In addition, Yumoto applies a clear accountability management mechanism: if an engineer breaks a cutting tool during machining, personal evaluation points will be deducted. This policy is intended to encourage engineers to learn from experience, enhance awareness of proper tool usage, and minimize the risk of production interruptions and negative impacts on product quality.
Appearance is a critical criterion, especially for products exported to the Japanese market.
Inappropriate or worn cutting tools may cause:
At Yumoto, the engineers who perform the machining directly inspect the appearance of the products they produce. When any abnormal signs are detected, the machining process is adjusted before the products are transferred to the QC department.
In precision machining, cutting tools have a direct impact on product quality and production stability. At Yumoto Vietnam, strict cutting tool management combined with clear engineer accountability helps control risks, reduce defects, and ensure full compliance with customers’ technical drawing requirements.
