1、 Overview of Transmission Gear Internal Grinding Machine:
The gearbox gear internal cylindrical grinder adopts a Japanese imported spindle and control system, which enables the machining accuracy to be the same as similar imported machine tools. The roundness and cylindricity can both reach 0.002mm. In addition, acoustic emission sensors are used to monitor grinding and dressing, and the number of dressing cycles is automatically adjusted to ensure the consistency of the grinding wheel state, greatly reducing the scrap rate and controlling it within 0.5 ‰. At present, the machine tool has been put into use and production in the south, and customers are very satisfied with the machining accuracy, stability, and other aspects of the equipment.

5Summary of Transmission Gear Internal Grinding Machine:
Shenyang Haimer carried out high-precision grinding of transmission gear internal cylindrical grinder, using self-developed HMN210 CNC internal cylindrical grinder and high-speed CBN grinding wheel instead of imported ones. This not only optimized the machining accuracy, but also automatically loaded and unloaded materials, one-time clamping, and real-time monitoring of grinding and dressing, greatly reducing the machining cycle and greatly improving production efficiency. The shift production (8 hours) increased from 120 pieces to 440 pieces, which satisfied customers very much.
