[Processing Example] High-precision gear grinding of large gears and long gear shafts.

[Processing Example] High-precision gear grinding of large gears and long gear shafts.

We are skilled not only in items with large outer diameters but also in long gear shafts and spline tooth grinding!

We would like to introduce our high-precision gear grinding services. We can process up to a maximum outer diameter of φ3,000, and by exchanging the head, we can also process internal gears. We excel not only in large outer diameter items but also in long gear shafts and spline grinding, achieving precision that exceeds the old JIS Grade 0 even for large gears. The probe unit equipped on our machine guarantees the precision of the gears through in-process measurement. 【Features】 ■ Capable of processing up to a maximum outer diameter of φ3,000, and can process internal gears by exchanging the head ■ Proven track record of processing gear shafts longer than 5m ■ Can achieve precision that exceeds the old JIS Grade 0 even for large gears *For more details, please download the PDF or feel free to contact us.

Introduction of processing examples! Capable of handling long-length processing and special gears.

Introduction of processing examples! Capable of handling long-length processing and special gears.

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.

Quality Control: High-Precision Gear Processing Using a Constant Temperature Room

Quality Control: High-Precision Gear Processing Using a Constant Temperature Room

To enable high-precision gear machining and gear polishing, gear grinding and measuring instruments have been installed in a temperature-controlled room!

To manufacture high-quality and high-precision gears, it is necessary to have a temperature-controlled room and machine tools capable of high-precision processing. Additionally, minimizing temperature fluctuations during the gear grinding process is crucial for improving product quality. At Inoue Iron Works, we have installed gear grinding and measuring equipment within a temperature-controlled room to enable high-precision gear processing and grinding. This allows us to produce gears with stable quality regardless of hot or cold days, or any season. 【Features】 - Installation of gear grinding and measuring equipment in a temperature-controlled room to enable high-precision gear processing and grinding. - Capability to produce gears with stable quality. *For more details, please refer to the PDF document or feel free to contact us.
