[Industry-Specific Case Study Introduction] Gears for the Automotive Industry

Suppressing the occurrence of grinding marks to achieve low-noise gears. We create quiet and strong gears!

Due to changes in the mechanical structure, rigidity and control capabilities have improved, allowing for the production of high-precision gears at approximately twice the speed of the conventional machine (RZ362A) by using a newly developed grinding wheel. This system suppresses the grinding marks generated by conventional grinding methods, achieving low-noise gears (LNS: Low Noise Shifting) and eliminating ghost noise that occurs in the fourth order. Furthermore, a special grinding method (Cool Cutting) significantly enhances the surface pressure strength compared to traditional grinding methods. 【Features】 ○ REISHAUER RZ400 - Improved rigidity and control capabilities - Capable of producing high-precision gears at approximately twice the speed of the conventional machine (RZ362A) - Suppresses grinding marks and achieves low-noise gears (LNS: Low Noise Shifting) - Eliminates ghost noise that occurs in the fourth order - Significantly improved surface pressure strength compared to traditional grinding methods Users of OJIC's gear products receive 100% fully customized gears processed based on the designs of approximately 100% of users. If you have any developments or issues regarding precision gears, please feel free to consult with OJIC, a specialized gear company. *For more details, please refer to the PDF materials or feel free to contact us.

[Production Example] Gears as Designed

A must-see for the automotive industry! Compared to conventional methods, highly flexible tooth shape and tooth profile modifications are now possible.

We accept the production of "gears as per design." The dressing mechanism is controlled by NC for all axes, allowing for stabilization of tooth profiles through special modules, pressure angle corrections, and changes in the engagement ratio. Furthermore, by performing contour dressing with a single diamond, the need for special tools for complex tooth profile corrections has been eliminated. [Production Examples] ■ Special modules and pressure angle corrections ■ Stabilization of tooth profiles through changes in the engagement ratio ■ Contour dressing with a single diamond, eliminating the need for special tools for complex tooth profile corrections *For more details, please refer to the PDF document or feel free to contact us.
