Automotive tooling and equipment parts: Pins | Precision machining examples
Examples of the production of "pins," which play an important role in precise positioning of objects and as guides for mechanisms in automotive parts assembly lines and inspection equipment.
In this case, parts with elongated shapes such as "diameter 2mm, length 50mm (Φ2×50)" are prone to material displacement or bending due to the pressure of the cutting tool during machining, making it very difficult to maintain micron-level precision uniformly. However, our company ensures that even these high-difficulty slender parts achieve strict dimensional tolerances of ±0.001mm and a smooth surface roughness of Rz 0.4μm, thanks to our advanced cutting know-how accumulated over many years and optimal processing approaches. This technology helps prevent play and positional misalignment in our customers' manufacturing lines, contributing to high-precision assembly. For the material, we use stainless steel "SUS303," which excels in the balance between rust resistance and machinability. Even for small lot requests of "5 pieces," which are required for maintenance of dedicated equipment or spot tooling production, we deliver quickly under a reliable quality assurance system with 100% inspection.
