Due to the angled bottom surface of the valve components, measurement using a 3D measuring device was not possible, so measurements were conducted using a gauge. In this case, we received the valve components from the customer and examined how to perform the measurements, providing a consistent response from design to manufacturing. There are a total of 12 holes, both large and small, and by measuring each one with the gauge, we successfully achieved a significant improvement in work efficiency compared to measurements using general-purpose machines. 【Product Attributes (Specifications)】 ■ Product Classification: Cover/Case ■ Industry: Automotive ■ Material: Sintered Metal ■ Size: 100mm × 70mm × 50mm ■ Measurement Item: Hole Position Measurement ■ Measurement Tolerance: ±0.01mm *For more details, please refer to the PDF document or feel free to contact us.
