Grinding machine highlights achievements to break international technical barriers

Abstract: It is understood that at present, China needs to import about 300 optical profile grinders and various kinds of multi-functional precision surface grinders every year, each priced at hundreds of thousands of dollars. The 14 orbital plate grinders have increased the sales revenue of Hangzhou-Zhejiang over 100 million yuan. At the same time, they have also broken the technical barriers and blockades of high-speed railway construction in developed countries, resulting in higher social benefits for Hangzhou Machine.

It is understood that at present, China needs to import about 300 optical profile grinders and various kinds of multi-functional precision surface grinders each year, each priced at hundreds of thousands of dollars. To this end, the domestic machine tool companies to improve grinding technology research and development, breaking the international technology blockade abroad has become a critical task. Under the strong support of the economic recovery's development situation and national policies, China's grinding machine enterprises have carried out structural adjustments and industrial upgrading, further developed new types of grinding machines and new grinding technology, and achieved significant results in grinding R&D projects.

Hangzhou Machine Tool successfully developed the high-speed railway track plate grinding machine. State Machine Tool Group Co., Ltd. developed the MKB7025 CNC track plate grinding machine, which is one of the high-speed rail construction heroes. The first set of orbital plate grinders has created an unprecedented speed record for the development of new products from design, manufacture, installation and commissioning. It has been hailed as “high-speed rail” for the purpose of innovative R&D of track plate grinders for high-speed rail construction. The track plate grinder developed by the Hangji Group has continuously improved production efficiency and created a good record of processing 120 rail plates per day.

In the process of researching and developing track plate grinders, on the basis of digesting and absorbing advanced technologies, Hangzhou Machines attached great importance to technological innovation and achieved a number of innovative technological achievements. This series of products has obtained three patented technologies granted by the National Patent Office: "Girder Moving CNC Grinding Machine" with gantry frame-type overall movement method; "High-speed locking mechanism of grinding head rotary shaft" "The device" adopts advanced hydraulic automatic load-bearing, automatic leveling and stress-free clamping technology for the heavy-duty workpiece of 9 tons, such as "large-scale workpiece hydraulic support leveling and clamping device".

The 14 orbital plate grinders have increased the sales revenue of Hangzhou-Zhejiang over 100 million yuan. At the same time, they have also broken the technical barriers and blockades of high-speed railway construction in developed countries, resulting in higher social benefits for Hangzhou Machine.

Shanghai Machine Tool Factory launched a new generation of high-precision cylindrical grinders based on the combination of years of technological research and development results, this year, the machine successfully launched a new generation of high-precision cylindrical grinder. The maximum rotary diameter of the machine is 芰500mm, the maximum workpiece length is 3000mm, and the maximum workpiece weight is 1000kg. The machine tool adopts the company's newly developed high-efficiency, high-precision dynamic and hydrostatic bearings, and adopts a bearing support structure with independent intellectual property rights, and on the basis of fully guaranteeing the high-precision, high-speed, uniform slewing support of the spindle, it realizes grinding with a large amount of cutting. The grinding efficiency is more than three times that of the original model. Based on the breakthrough of high-efficiency grinding technology, this product can achieve coarse grinding and super-finishing with the same type of grinding wheel without replacing the grinding wheel. The high grinding rate reduces the loss of the grinding wheel and can achieve a higher amount of grinding under the same motor power conditions.

These R&D achievements were applied for the first time in the country, realizing high-efficiency and high-precision grinding in a real sense. The development of the overall technology of the grinding machine has been upgraded to a higher stage, and at the same time, the energy saving and consumption reduction and the quality stability have been greatly improved. This new product can be used as an exemplary model of advanced manufacturing technology. Technological innovation, quality improvement, and perfect marketing and service mechanisms have injected new vitality into the brand's strategic activities of the company. It not only enhances the overall strength of the company, but also creates value-added potential for its customers.
