NC Seiko of precision parts
We process various precision parts such as components for semiconductor manufacturing and inspection equipment, as well as medical device parts.
We specialize in ultra-fine processing (prototyping, small lots)!
Our company has cultivated a wealth of processing technology and know-how over many years. We are committed to "speed and accuracy," and we are confident that you will be completely satisfied with our services. When we receive orders for small production items (including prototypes), we will create simple molds necessary for processing. Depending on the product, items that cannot have burrs will undergo metal etching processing before bending.
We respond to the growing demand for ultra-small precision parts processing in various fields.
GOTO Seiki Co., Ltd. specializes in the precision machining of extremely small components that are in high demand across various fields such as cameras, semiconductors, optical fibers, and connectors. We handle tiny parts ranging from about the size of a 10-yen coin to approximately the size of a grain of rice. Despite being small, our capabilities range from simple processes like drilling and grooving to complex shapes and three-dimensional forms. To achieve this, we create original mounting jigs and pursue positioning accuracy through repeated multi-process operations. Our cutting tools can combine to achieve a minimum radius of R0.05 and drilling diameters as small as Φ0.03, making the impossible possible. Burrs, which can be a significant issue during machining of tiny parts, are addressed through our pursuit of methods that eliminate them, and any remaining fine burrs are removed using our unique expertise. For more details, please contact us.
Publication of miniaturized and refined component processing technology for medical devices and semiconductor inspection parts!
We are considering miniaturizing our products, but we lack the manpower to process them in-house. If you are facing challenges such as being unable to respond technically, please consult with us. Aikosha specializes in NC precision machining and processes fine parts such as contact probes for electrical testing of fine components (semiconductors, printed circuit boards, etc.), medical device parts, and industrial equipment parts. With NC machining, we can handle fine parts with an outer diameter of "0.05 mm to 6.0 mm." In drilling operations, we have a technical track record of achieving a minimum hole diameter of "0.009 mm (depth 1.0 mm)," and we are committed to high-precision manufacturing. We are pursuing new fields where we can further utilize the fine processing technology and know-how we have cultivated over many years, particularly in semiconductor inspection parts. If you are considering further miniaturization or fine parts, please consult with us. Currently, we are partially showcasing examples of fine parts processing! *For more details, please download the catalog or contact us directly.
Processing fine parts that cannot be manufactured with existing machine tools using in-house developed tools and automatic machines, along with prototypes and mass production [brochure with case studies].
Super parts from 1 to 10 billion! We can process fine parts that cannot be manufactured with existing machine tools using our self-developed tools and automatic machines, enabling prototyping and mass production. Medical device manufacturing industry (Registration number 13BZ201153) 【What We Can Do】 3D grinding of needle-like tips Processing needle-like tips into cutting tools or tapers Drilling with our self-manufactured φ10μ drill Processing small items that can be confirmed under a microscope, such as medical and semiconductor inspection parts Grinding of wire with a diameter of 25μ Straightening of fine wires Automatic correction of thermal displacement and cutting edge wear using image recognition In 2008, we received the "100 Craftsmen of Ota Ward" award. We solve problems with fine skills such as grinding, cutting, ultrasonic, electrolysis, discharge, and laser. *For more details, please download our catalog or feel free to contact us.
