Runsom Precision provides three-
four-, and five-axis CNC machining, Swiss-style automatic lathe machining, and micro-machining services. Its standard tolerance, when not otherwise specified, is ±0.005 inch (±0.127 mm).
However, for certain equipment and conditions, it can achieve extremely tight tolerances of just ±0.0025 mm. For finishing, it can perform anodic oxidation, plating, bead blasting, polishing, and other surface processing. The required smoothness can be selected based on the designs and processes involved.
It works with diverse materials, including aluminum and titanium, and supplies component manufacturing services to fields such as the communications, optics, and electronic enclosure fields.

First, clarify which types of processing you would like to request, and then confirm their processing precision, the number of axes of their machines, and the types of materials they work with. Different companies have different fields of expertise depending on their equipment configurations (three- or five-axis machines, Swiss-style automatic lathes, etc.), so it's important to determine if these match your own design requirements.
Next, you should confirm their tolerance management systems, inspection systems, and quality assurance frameworks, including ISO certification, to determine if they can maintain a stable level of quality. Before getting an estimate, clearly indicate tolerances, material quality, and surface processing in drawings and inform the company of the number of lots and turnaround time. This helps prevent problems and makes future dealings progress more smoothly.
