We will introduce examples of processing gears with teeth cut on a flat plate or rod, known as "rack gears."
Here are some examples of processing cases for "rack gears" that we have handled. "Rack gears" are gears with teeth cut into flat plates or rods, which can be combined with a small gear called a pinion to convert rotational motion into linear motion, or vice versa, converting linear motion into rotational motion. Rack and pinion systems, which combine rack gears and pinions, are used in various industrial fields such as printing machinery, industrial machinery, conveyor systems, machine tools, and transport machinery. [Processing Examples] ■ Details: Various types (round/rectangular) rack gears ■ Materials - Various carbon steels, alloy steels, stainless steels - Module: Up to 12 - Capable of high-frequency hardening, carburizing, nitriding, etc. ■ Achievements: General machinery, etc. *For more details, please refer to the related link page or feel free to contact us.

We specialize in various gears and long-length machining, including long splines, bevel gears, spur gears, involute splines, and square splines.
Our company has been dedicated to gear cutting since 1948, cultivating our technology and knowledge. We own five Japanese-made horizontal screw milling machines and specialize in gear cutting for long shafts. 【Processing Examples】 ■ Long Spline While we excel at thick and long items, our true strength lies in cutting slender spline gears. We have a track record of processing a spline of 6500mm on a shaft with an overall length of approximately 7000mm (outer diameter φ48). Processing thin shafts requires considerable experience. Since processing distortion can occur and is influenced by material selection and lathe quality, please consult us in advance. ■ Bevel Gears Bevel gears are very labor-intensive, and the number of companies capable of processing them continues to decrease. The processing itself is time-consuming, and managing the details requires extensive knowledge. It is rare for a lathe to be functioning properly, and there may be errors in the drawings, so please consult us before lathe processing. ■ Spur Gears These are standard gears, but our company can cut gears with an outer diameter of around φ1500 (approximately grade 4). *For more details, please download the PDF or contact us.

A reliable and powerful way to transmit force! It is used in various machines.
A gear refers to a mechanism that transmits power through continuously interlocking teeth. Other transmission methods include chains and belts, but gears are a reliable and powerful means of transmitting force, excelling in their ability to transfer power smoothly without slipping. Additionally, by changing the shape, pitch, and number of teeth of the gear, it is possible to adjust the range of power transmission, rotational speed, and torque, making them applicable in various machines. *For more details, you can view the related links.
