On March 17–18, 2026, the working group for the development of the national standard “Precision Testing of Laser Tool‑Machining Machine Tools” convened a seminar at the Beijing Electrical Discharge Machining Research Institute. The meeting aimed to discuss and refine the draft of this national standard. Attending were 17 expert representatives from 10 organizations, including Beijing Ande Jianqi, the Beijing Electrical Discharge Machining Research Institute, Guangzhou Yuandian Intelligent, Shenzhen Muji, the Suzhou Electrical Discharge Machining Research Institute, Shenzhen Han’s Laser, Shandong Haomai CNC, Guangdong University of Technology, Zhejiang University of Technology, and the China Machine Tool & Tool Association. The session was chaired by Wang Ying, Secretary-General of the National Special‑Purpose Machine Tool Standards Committee.
In mechanical machining and manufacturing, cutting tools used to machine metals and other materials have evolved in their core materials—from high-speed steel to cemented carbide, ceramics, and superhard materials such as polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PCBN). Consequently, tool performance—including cutting speed, workpiece surface quality, and dimensional accuracy—has steadily improved. In recent years, superhard‑material cutting tools, prized for their high machining efficiency, superior surface finish, and extended tool life, have found widespread application in key industrial sectors like automotive manufacturing, aerospace, and mold making. The fabrication of superhard‑material tools has likewise advanced from conventional metal cutting and grinding to specialized processes such as electrical discharge machining (EDM), EDM wire‑cutting, and laser processing, effectively addressing longstanding challenges associated with the difficult machinability and low productivity of these materials. Beijing Ande Jianqi has kept pace with trends in superhard‑tool manufacturing technology. Since 2006, it has introduced a series of advanced manufacturing equipment to the industry, including precision CNC EDM machines for superhard‑tool machining, CNC EDM reciprocating wire‑cutting machines for superhard‑tool production, and five‑axis laser machining centers for superhard‑tool processing, thereby providing reliable support for green, efficient, precise, and intelligent manufacturing of superhard tools. To standardize the research, development, production, and acceptance of laser‑based superhard‑tool machining centers, in 2023 Beijing Ande Jianqi, together with the Beijing Electrical Discharge Machining Research Institute and other organizations, submitted a proposal to the National Special‑Purpose Machine Tool Standardization Technical Committee to develop technical specifications and industry and national standards for laser‑based superhard‑tool machining centers and precision‑inspection criteria. In 2024, both the technical specification and the precision‑inspection standard were officially approved at the national level.
During the meeting, Dr. Jia Yunhai from the Beijing Electrical Processing Research Institute, the project’s lead institution, presented in detail the draft standard “Accuracy Inspection for Laser Tool‑Machining Machine Tools,” along with the feedback received and the corresponding revisions. The participating expert representatives engaged in thorough discussions on key inspection items in the draft, including geometric accuracy, positioning accuracy, and working accuracy. In particular, they deliberated on the selection of a representative ultra‑hard tool‑machining scheme as the benchmark for assessing working accuracy. Several machine‑tool manufacturers offered constructive and practical suggestions, laying a solid foundation for the timely and successful completion of this national standard. Following this seminar, the draft standard “Accuracy Inspection for Laser Tool‑Machining Machine Tools” is expected to be finalized as a review draft by the end of March.
Concurrently, a seminar was held to revise two industry standards: “CNC Electrical Discharge Grinding Machines for Superhard Cutting Tools—Part 1: Accuracy Verification” and “CNC Electrical Discharge Grinding Machines for Superhard Cutting Tools—Part 2: Technical Specifications.” Beijing Ande Jianqi is one of the drafting organizations for these two standards and will continue to participate in their revision process.
