日東工作所 Company Overview

Nitto Kōsaku Co., Ltd. (Osaka) is a comprehensive manufacturing company that supports production through "jig expertise × precision machining." [Reasons Why Jigs Are Necessary | Limitations of Manual Work and Variability in Quality] In the previous discussion, we introduced the basic definition of "jigs." This time, we will explain the background of the necessity for jigs, focusing on the "limitations of manual work," using relatable examples. ☆ When Undertaking the Job of Sharpening Pencils At our company, we explain the concept of "jigs" in an easy-to-understand manner using familiar examples during lectures and presentations. For instance, let's say we take on the job of sharpening pencils from a certain company. If this is done manually with a knife, there will be variations in the angle of sharpening, the length of the lead, and the finished shape depending on the worker. There will also be differences in the time taken to complete the work, leading to challenges in standardizing quality and improving production efficiency. To stabilize "work that is influenced by human skill," jigs are necessary. By using jigs, anyone can process the pencils at the same position and angle, enabling stable production with reduced variability in quality. Our company leverages this concept of jig creation to engage in precision machining, prototype production, and the design and manufacturing of dedicated machines. To be continued.

Nitto Kousakusho Co., Ltd. (Osaka) is a comprehensive manufacturing company that supports manufacturing through "jig expertise × precision machining." We will introduce the concept of "jigs," which is the foundation of our company, in several installments. When our representative, Saraya, speaks at lectures and technical seminars about machining, jigs and dedicated machines, and rotary engine (RE) development, he always touches on "jigs." This concept has been passed down since the time of our founder, Isamu Saraya, and is the origin of our machining practices. Our particular strength lies in jigs for machining. The know-how in jig design and manufacturing that we have cultivated over many years in the field is applied to precision machining, the design and manufacturing of dedicated machines, and even RE development. We define jigs as "auxiliary tools that fix the workpiece in the correct position during processing or assembly and guide the work." Based on this concept, we have focused on the impact of jig innovations on machining accuracy and work efficiency in our manufacturing efforts. In future installments, we will introduce Nitto Kousakusho's manufacturing philosophy, incorporating examples. (For more details, please visit our blog: https://nitto-mfg.com/20260315_jig1j/)
