The 1250mm YH6012 CNC Spiral Bevel Gear Milling Machine was successfully developed.

The YH6012 CNC spiral bevel gear milling machine with a diameter of 1250mm was successfully developed by Tianjin Jingcheng Machine Tool Manufacturing Co., Ltd. (formerly Yuanhao Electromechanical Development Co., Ltd.). The Tianjin Science and Technology Commission organized expert appraisal, the machine tool not only filled the domestic gap, reached the international advanced level, and the processing diameter is currently the leader of similar machine tools in China.

Experts believe that the development of the machine tool was successful.

First, it ended the history of China's large-scale CNC gear machine tool development relying on the introduction of surveying and mapping, transformation and imitation. Jingcheng Company independently innovates with its own scientific research strength, so that the machine tool has independent intellectual property rights.

The second is to show that China's gear machine tool manufacturing industry has the ability to challenge the authority of the world. The machine tool not only uses CNC four-axis servo drive, but also hobbing and milling spiral bevel gears, zero-degree bevel gears and hypoid gears, and successfully applies the most advanced coordinate axis design in the world to larger machining diameters. Among new products.

The third is to help China get rid of the oversized machining diameter of the gear milling machine subject to foreign conditions. With the increasing size and high precision of the main equipment in China's cement, metallurgy, water conservancy, automobile, hydropower, coal, petrochemical and other industries, the demand for heavy-duty spiral bevel gears is increasing. The most conservative estimate is that the annual demand should be between 500 and 600 pairs. After the machine tool is introduced, it can not only meet the trial production of heavy-duty spiral bevel gears of many varieties and small batches, but also adapt to the mass production needs of batches.

According to the person in charge of Jingcheng Machine Tool Co., the next step is to put the CNC spiral bevel gear milling machine with a diameter of 1600mm into the key research projects, and strive to take out the prototype in a year or so. By then, we will be able to fully equip our country with the ability to process larger and larger spiral bevel gears.

HP Main Frame Assembly

HP Cone Crusher


(1) The limited crushing level can be used to produce finer products. Reduce maintenance downtime and increase the confidence of operators.


(2) Use the two-way iron passing release hydraulic cylinder to discharge the iron block, and implement the cleaning operation of the crushing chamber with large eccentricity when necessary. Dual accumulators can improve the response speed of the hydraulic system.


(3) HP series cone crusher can ensure the highest personnel safety and convenience of maintenance.


(4) The convenient disassembly and assembly of all key components from the top of the crusher, the convenient replacement of the lining plate, the one button fixed cone rotation disassembly function, the lining plate without the use of filler, and the comprehensive operation protection of the ICTM automation system all make the HP series the most reliable cone crusher.
