Doesn't shift, doesn't loosen. Achieving 'just fit' with a finishing precision of ±5μm from just one piece.
A functional component that achieves both "positioning accuracy" and "smooth insertion." The reamer bolts finished with Ikesawa grinding have an extremely high outer diameter tolerance of ±5μm, ensuring a "play-free fit" during positioning, press-fitting, and assembly processes. Through 27 process management practices that embody the "feelings of the users" cultivated in the Honda and Isuzu fields, we guarantee a quality that can be immediately introduced into the production line after delivery. Unique strengths and technologies: Unique burr removal on the escape section + centerless grinding: Directly contributes to extending tool life and reducing assembly time. Achieves a smooth "neck" that does not damage the counterpart material during press-fitting. Quality assurance through "skilled five senses": We issue a full inspection certificate and store data for 15 years. We respond to the trust of the precision machinery and robotics industries that do not allow for recall risks.

Applications/Examples of results
Robots and automation equipment: Eliminating play at joints and sensor mounting points, dramatically improving the reproducibility of movements. Truck parts assembly line: Adopted as guide pins for positioning body and engine parts. **"Enabling stable assembly even without skilled workers,"** addressing labor shortages. Precision molds and jig parts: Suppressing burrs during press-fitting and maintaining high-precision positioning over long periods. "We are currently strengthening new recruitment in the robotics and advanced industries. Please try Ikesawa Polishing's 'fitting technology' 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.
