High-precision assembly parts that realize the moment of "feeling good as soon as you insert it."
This is a positioning pin component ideal for equipment that requires assembly precision, featuring high-precision centerless grinding finish. It is characterized by smooth fitting and dimensional stability. The positioning ring pins provided by Ikesawa Polishing achieve "not too tight, no play, and smooth fitting" in the assembly process. With high-precision centerless grinding of ±5μm, it helps suppress assembly errors and contributes to precise positioning. The surface is nearly mirror-smooth, allowing for stress-free handling even when fitting different materials together. 【Unique Technology】 Unique Technology: Dimensional adjustments by skilled craftsmen combined with micrometer sampling management. Features: The finishing quality is such that customers actually say, "It feels great the moment it fits" in their assembly environments. We can accommodate mass production as well as prototypes and small lots.

Precision Positioning Pins for Assembly (Industrial Products and Unit Components) Detailed Description: These "positioning pins" are essential for preventing "misalignment" and "play" between parts. They smoothly fit into the holes of jigs and cases during assembly, reducing the effort of press-fitting and assembly errors. They are ideal for precision units in automobiles, motorcycles, and industrial machinery. Target Industries: Automotive parts, motorcycles, FA equipment, electrical enclosures, robots, precision assembly lines [Assembly Jigs and Inspection Jig Components for Industrial Machinery] In assembly jigs where dimensional control is crucial, they are used as guide pins to insert products in the correct direction and position. A smooth finish that prevents fitting errors and wear during insertion and removal directly contributes to the longevity of the jigs. Support is available even from a single piece during the prototype stage. There are many repeat orders from equipment manufacturers and device development companies.
