Hob machines with high precision processing and high reliability *Active in countries around the world!
Introducing the hob machine, a completed masterpiece that is active in countries around the world! It boasts high reliability with high-precision processing.
We would like to introduce the "Hob Machine" handled by Hamai Sangyo Co., Ltd. For high-precision gear processing, gear grinding is usually performed after gear cutting. However, our hob machine can finish small module gears, which are difficult to grind, to a precision comparable to that of grinding. It is active in a wide range of fields related to small gear processing, including wristwatches, power tools, fishing gear, stepping motors, and electrode processing for gear molds. We boast a shipping record of approximately 7,000 units to date. 【Product Lineup】 ■ N80: Pursuing high precision and high performance ■ N60: High production performance ■ N40: Compact and quality-focused ■ GN150: Pursuing high precision and high performance *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Features** ■ Dry Cutting (N60・N80) - The maximum rotation speed is set to 5,000 min-1 to enable high-speed dry processing with a carbide hob cutter. - Processing time is 5 to 7 times more capable than conventional processing, achieving higher precision. - Simplification of processes is possible as workpieces can be processed directly after heat treatment. ■ Loading Device (N40・N60・N80) - Various loading (automatic supply) devices tailored to specific workpieces are available. - By combining with magazine systems and palletizing devices, complete automation is achievable. ■ Automatic Hob Grinding Machine (GN150) - The addition of a tailstock increases the holding rigidity of the hob arbor, reducing cycle time to 1/6 compared to conventional machines. - The use of servo motors for indexing and table feed allows for simplified setup. *For more details, please refer to the PDF document or feel free to contact us.*
