Technology for a minimum diameter of φ0.1μm! Introduction of high-precision, high-quality precision micro-hole processing examples.
In addition to press processing, drilling, and electrical discharge machining, we propose processing methods such as laser processing and FIB processing according to your needs! *Case study collection is currently available!
Our company began with the manufacturing of spinnerets, which are key technologies in synthetic fiber production. The most important aspect of spinneret manufacturing is the fine hole processing technology that ensures the discharge holes for synthetic resin are finished with high precision and high quality. The accuracy of the discharge hole diameter is ±2μm, and the inner walls of the discharge holes are finished to a uniform roughness, with sharp edges free of burrs. Based on fine hole processing technology, we have expanded our variations to include press processing, micro-drilling, electrical discharge machining, laser processing, and FIB processing. We offer tailored processing methods for dispenser nozzles, inkjet nozzles, orifices and apertures, transparent materials (glass, film), biological filters, as well as in the semiconductor, aerospace, and medical device fields.

basic information
【Processing Methods】 ■ Press Processing It is possible to mass-produce extremely fine holes using special press tools. After processing, post-treatment such as cleaning, burr removal, and polishing is performed to achieve a high-quality finish. ■ Micro Drill Processing This method uses fine drills for hole processing, achieving small hole diameters and high aspect ratios for deep holes. It is also capable of processing straight sections of deep holes with stable high precision, which is often considered difficult. ■ Ultra-Fine Electric Discharge Machining Suitable for processing high-hardness materials that are difficult to machine with drills or presses. ■ Laser Processing This method involves irradiating the workpiece with a laser to melt and process it. Our uniquely developed laser micro-processing technology enables high-density precision micro-hole processing. ■ FIB Processing This processing method involves irradiating a focused ion beam onto the workpiece, knocking off the surface atoms of the work material. The beam is extremely thin, at several tens of nanometers, and the irradiation area is small, allowing for high-precision and high-quality processing from several microns to the nanoscale. *If you would like to see other fine processing technologies from Toray Precision, please click the URL to check our company website.
