Realizing the moment you insert it, it's pleasant. Achieving ±5μm precision to eliminate any wobble in robots and precision equipment.
In robotic joints and precision automation lines, even a slight "play" can lead to fatal errors. The positioning guide ring pin provided by Ikesawa Polishing achieves ultra-precision tolerances of ±3 to 5μm in outer diameter. Through a unique 27-step management process and skilled grinding utilizing the "five senses," we offer the best fit described as "sticky fit" in our customers' workplaces, ensuring it is "not too tight, no play, and smooth fitting." We bring to life the designers' wish for "just a little more precision." Unique Strengths and Technologies: Dimensional adjustments using the "five senses" of skilled artisans: We achieve final finishing quality that cannot be measured by micrometer values alone, delivering what customers actually describe as "pleasant" in their assembly environments. Thorough quality control through "27 processes": In addition to cleaning, rust prevention, and individual packaging, we issue inspection certificates for all items and maintain data for 15 years. This enables direct integration into our customers' assembly lines, minimizing recall risks.

Applications/Examples of results
Industrial robots and collaborative robots: High-precision positioning of joint units and arm connections. Dramatically improves the reproducibility of movements. Precision inspection devices and sensor mounting points: A foundation for mechanisms where vibration and misalignment are not tolerated. Reliability guaranteed with 15 years of data storage. Guide pins for assembly jigs and inspection jigs: Smooth finishes that prevent fitting errors and wear directly contribute to the longevity and stable operation of jigs. We are currently strengthening new recruitment in the robotics and advanced industries. Please try Ikesawa Polishing's "fitting technology" starting from a single prototype.
Company information
We promise a manufacturing process where you can see the "difference" the moment you assemble it. 【Do you have these concerns?】 - Even though it was made according to the drawings, assembly is cumbersome. - I want small lot production during the prototype and development stages. - Difficult-to-machine materials (such as hardened steel). Ikezawa Polishing can solve these problems. 【Reasons why Ikezawa Polishing is chosen】 - High-precision grinding processing in micrometer units (±5μm tolerance). - Capable of handling difficult-to-machine materials like hardened steel. - Flexible response and short delivery times thanks to our small team. - Trust and track record built over more than 40 years of operation. 【Delivery achievements】 - Automotive and truck parts (reamer bolts, ring pins). - Printing machine parts (roller shafts). - RC engine parts for fuel (piston valves, crankshafts, throttle valves). - Hydraulic equipment parts (piston valves, oil seals, jack shafts). - Motorcycle brake parts. - Precision parts for industrial machinery. 【Media achievements】 Published in the Japan Machinery Newspaper on December 20, 2024.
