CNC Precision Grinding Machine Opens a New Situation in Starting a Business

The use of precision grinding machines in the domestic industry has become more and more extensive. In particular, the industry's grinding machine company has carefully researched and developed various new types of grinding products and achieved important project results. It has broken the international blockade of grinding machines and created a good new situation.

Hangzhou Machine Tool Group Co., Ltd. developed the MKB7025 type 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.

Shanghai Machine Tool Plant launched a new generation of highly efficient cylindrical grinding machines. The machine's maximum rotary diameter is mm500mm, 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.

The tool-specific machine tool SK722 CNC tap thread grinder developed by Chengji Tools Group Co., Ltd. at CIMES2010 is used for the tap thread processing. The multi-line grinding wheel is used for workpiece grinding, equipped with a diamond wheel automatic grinding device, and high precision is selected. The CNC closed-loop control system is easy to operate and program. Because the finite element analysis software was used to optimize the design of the machine tool structure, its overall rigidity was improved.

The CNC Precision Grinding Machine of Sanming Machine Co., Ltd breaks the international technology blockade situation and Xiamen University jointly undertakes the major topics of the "Eleventh Five-Year Plan" Major Special Project "R&D and Application of Advanced Mechanical Equipment and Key Technologies". Development and Application of Grinding Machines and Key Technologies" Accepted by the Expert Group of Fujian Science and Technology Department. The project produced the first four-axis CNC precision grinding machine in China. This technology has filled the domestic gap and broke the international technological blockade at one stroke. In early June of this year, the precision grinding machine was sent from a Sanming machine to a Chengdu unit and was formally used for production.
