This service is a machining service that focuses on deep hole processing with a diameter of less than φ3mm, which is required for parts in the medical and precision fields, and provides technical consultation from the design consideration stage. As the diameter decreases and the length increases, it becomes more challenging to determine the feasibility of machining and set tolerances, so we organize machining methods and dimensional conditions from the stage when the drawings are not finalized. Utilizing setup and machining know-how that takes into account core misalignment and straightness, we offer proposals for machining methods that are practical and feasible. We also have experience with φ0.5mm class parts, but we consider them on a case-by-case basis depending on the conditions, emphasizing realistic feasibility judgments. We can also accommodate feasibility checks for prototypes and small lots. **Features** - Specializing in deep hole machining with a diameter of less than φ3mm - Technical consultation available even when drawings are not finalized - Proven machining experience in the medical and precision fields - Honest proposals that prioritize feasibility "This service is designed for consultations starting from the stage of wanting to confirm whether machining is possible." *For more details, please download the PDF or feel free to contact us.*
