Since our foundation in 1921, we have been true to Hamai’s corporate mission of “contributing to industrial progress with unwavering cutting-edge quality precision machine tools.” We produced Japan’s first lapping and polishing machines, and have been manufacturing gear hobbing machines since the beginning. Even though their forms and shapes have evolved, these unsurpassed machines are still Hamai’s core products today.
With the era of “Information and Communication Technology” rapidly unfolding, we believe that our products and services play even more significant roles, as our customers and markets become more and more globalized. In order to continue to meet our customers’ demands, all of us at Hamai are determined to earn your trust with our enhanced efforts in delivering cutting-edge technology.
Features
Dry hobbing:N-series
The maximum rotation speed of the hob is 5,000 min-1 to perform hobbing dry cutting with a carbide hob cutter.
Hobbing speed has increased to 5 – 7 times that of the conventional machines with higher precision. Can hob heat-treated works as they are, allowing simplified hobbing process.
Loading System:N-series and SP series
Various types of loaders are available that can handle your works automatically. Such loaders, when combined with magazines and palletizers, enables completely unmanned operation of your hobbing machines.
High-accuracy hobbing
To manufacture high-accurcy gears, hobbed gears are generally ground. Our hobbing machines can hob small gears, which cannot be ground, to an accuracy that can be achieved by grinding.
Highly reliable
Used widely to produce small gears for electric tools, wrist watches, electric tools, fishing tackles, stepping motors, and electrodes for gear molds. To date, we have manufactured about 7,000 units.
Automatic hob re-sharpening machine:GN150
The hob arbor is provided with a tail stock center for the support to increase the holding rigidity of the hob arbor, thereby shortening the cycle time to one-sixth of the former model. The indexing head and the table are driven with a servo-motor, allowing simplified preprocess.
