A grinding machine is a type of machine tool that is used to shape or finish the surface of a workpiece using a grinding wheel or other abrasive tools. According to data from the China Machinery Industry Federation, between January and September 2012, the national grinding tool industry achieved a total industrial output value of 568.07 billion yuan, representing an 11.37% year-on-year increase. The sales value for the same period reached 550.687 billion yuan, up by 11.04% compared to the previous year. Additionally, the export delivery value of the grinding tool industry reached 33.764 billion yuan, reflecting a significant growth of 16.39% year-on-year.
Currently, Chinese grinding companies are actively optimizing their product structures and investing in the development of new grinding machines and advanced grinding technologies. Several major breakthroughs have been made in R&D projects related to grinding machines, demonstrating the industry’s growing innovation capacity and technological advancement.
One notable example is the MKB7025 CNC track plate special grinding machine developed by Hangzhou Machine Tool Group Co., Ltd. This machine has played a crucial role in high-speed rail construction. It set a remarkable speed record in the development cycle, from design and manufacturing to installation and commissioning. The machine has been widely recognized as a key innovation in high-speed rail infrastructure, with its ability to process 120 track plates per day, significantly boosting production efficiency.
Another example is the new generation of high-efficiency precision cylindrical grinding machine introduced by Shanghai Machine Tool Factory. With a maximum turning diameter of 500mm, a maximum workpiece length of 3000mm, and a weight capacity of 1000kg, this machine is equipped with a newly developed high-efficiency and high-precision dynamic and static pressure bearing. Featuring a proprietary bearing support structure, it ensures high precision, high speed, and uniform rotation of the spindle, enabling large cutting amounts and increasing grinding efficiency by more than three times compared to previous models.
Chengliang Tools Group Co., Ltd. showcased the SK723 CNC taper thread grinder at CIMES 2010, a specialized machine designed for processing tap threads. This machine uses a multi-line grinding wheel and features a user-friendly CNC closed-loop control system, making programming and operation more straightforward. The structural design was optimized using finite element analysis software, resulting in improved overall rigidity and performance.
In addition, Sanming Machine Tool's CNC precision grinding machine broke through international technical barriers. It was part of the "Eleventh Five-Year" major special project in Fujian Province, focusing on the development and application of advanced mechanical equipment and its key technologies. The project successfully passed expert review and marked the introduction of the first four-axis CNC precision grinding machine in China, filling a domestic gap and breaking the foreign technology monopoly.
These developments highlight the continuous progress and global competitiveness of China's grinding machine industry.
