In order to fill the gap of domestic self-developed high-precision servo direct drive CNC electric screw press, Newwish began to project the development of J58ZK-2500 servo direct drive CNC electric screw press prototype in January 2021, after a year of continuous improvement, improvement and optimization. In January 2022, under the organization of Dr. Yu Jun, Vice president of technology and Director of Technology Center, the backbone members of the company's product development department, process Department, Electrical and Information Department, Quality Management Department and experts from the expert advisory room jointly formed the company's Technical Committee. The design index and performance of 25000KN large tonnage servo direct drive CNC electric screw press are tested and accepted.

As the general manager of the 25000KN large-tonnage servo direct drive CNC electric screw press development project, Dr. Yu Jun shared the design ideas, product features, technical advantages of the product to the members in detail; Technical experts and committee members expressed their opinions from the product's structural integrity, rationality, reliability, product quality process control, product accuracy testing standards, key technical innovation points, Solutions to core technical difficulties, as well as safety measures during product operation, operational stability, noise conditions, impact on the environment, impact on personnel occupational health and other aspects have been fully understood and reviewed.

In the field performance test and dynamic acceptance process, under the strict requirements of the members of the technical committee combined with industry standards and international counterparts, The prototype precision, mechanical properties, effective energy and energy control accuracy, stability test, long-term allowable load shock test, noise test, safety function protection device operation test, voltage resistance, insulation resistance, ground continuity test and other dozens of performance and indicators were tested in all aspects. All the test results are in line with the design indicators and relevant standards stipulated in the project specification, and the project successfully passed the acceptance.
