Extra precision index gearings are the most essential parts of gear manufacturing machines. Chongqing Machine Tool Group Co., Ltd. (CHMTI) has put tremendous efforts in creative developing and numerous testing on the manufacturing technology of extra precision index gearings. CHMTI has a contingent of highly qualified engineers specially engaging in researching and developing extra precision index gearings and relevant test equipment. CHMTI possesses unique processing technology and complete processing testing equipment on high-precision cylindrical worm gearing, spherical worm gearing, and spherical worm gear-helical gearing, and cylindrical index gearing. The project “the production of extra precision worm with radial profile meshing with spherical worm wheel”won the Chinese patent of invention. The successes have established a strong foundation for CHMTI to rank in the leading level in the area of gear manufacturing machines and enables it to provide customers home and a abroad with indexing and transmission component of extra precision.
