4 Nissei creates high-quality high-precision gears in an integrated system of production from initial design to finished product. All the processes from receipt of order, design and manufacturing to delivery, are streamlined into a single system. Any type of order, whether it is a prototype or a mass production part, can be flexibly filled. KASHIFUJI Gear Cutting Machine KN-150 3

6 Acme of our original technology HRH(High Ratio Hypoid gears) High Reduction Ratio High Ratio Hypoid gears are the type of high reduction ratio gears which Nissei has successfully launched into the market for the first time in Japan. While the highest reduction ratio available on a one-to-one gearset used to be only approximately 10:1, HRH gears have made very high reduction ratio, available up to 360:1 on a one-to-one gearset. The general range of HRH reduction ratios actually used is 11:1 to 120:1. Our originally developed HRH gears are now used in the various fields such as Automobiles and Industrial machines with excellent performance. 5

8 Evolution of Processing Technique-CBN Grinding CBN grinding is a technique that the tooth surface is ground by CBN electrodeposited grinding stone after heat treatment. The technology cut machining time of tooth surface grinding remarkably. Also, dressing required per price for conventional grinding became unnecessary. realizing a serious cost reduction compared with conventional grinding. Since the tooth surface is ground by CBN grinding stone after heat treatment, about the same gear quality as ground gears can be obtained. Process Nissei's Proposal 1. What is CBN? CBN stands for "cubic boron nitride". 2. How the tools are made? Borazon CBN is electrodeposited onto the tool surface. CBN Particle Hardness (GE data) 7
