Recently, the 95th international meeting of ISO/TC 39/SC 2, the Sub-committee on Inspection Conditions for Metal Cutting Machine Tools under the ISO's Machine Tool Technical Committee, was held in Winterthur, Switzerland. The Chinese delegation focused on providing opinions regarding international standards for inspection conditions of gear hobbing machines and machining centers that China leads, as well as international standard projects such as general inspection principles for machine tools and gantry guide rail grinding machines that China participates in. They also proposed a review of the "Inspection of Gear Hobbing Machine Accuracy" standard and a proposal for the "Inspection of Gear Grinding Machine Accuracy", which is expected to be implemented in 2026.
June 18, it was reported that ASTM International, the American organization, launched an additive manufacturing certification program covering industries such as aerospace and healthcare. This program goes beyond the scope of existing standards like ISO 9001, AS 9100, IATF 16949, and ISO 13485. Its aim is to establish a single certification system recognized across multiple industries, reducing the need for repeated audits while ensuring manufacturers can demonstrate compliance with established additive manufacturing-specific requirements. (ASTM, the American Society for Testing and Materials, was formerly known as the International Association for Testing Materials.)
June 18, Zeiss released the XENOS CMM, which employs industrial ceramic guideways and four-sided ring-encircling air bearings technology. It achieves ultra-high precision of 0.3μm within a 1 cubic meter measurement space, with temperature fluctuations effectively isolated by a suspended glass ceramic grating scale. The machine supports AI visual path planning and 5G cloud data analysis. When applied to detecting aircraft engine blades, its four-axis scanning efficiency is increased by 70%.
On June 19, according to the plan of the National Standards Commission, a national standard work conference for two non-ferrous metal additive manufacturing standards, including \"Additive Manufacturing Powder Bed Fusion Aluminum Alloys\", will be held in Changsha from July 14 to 15, 2025.
June 21, it was reported that China total output value of the machine tool industry in the first half of 2025 reached 242.42 billion yuan, a year-on-year increase of 41.4%, among which the output of CNC machine tools was 945,000 units, a year-on-year increase of 52.2%, with a significant improvement in the proportion of high-end products. The profit of metal cutting machine tools was 2.27 billion yuan, a year-on-year increase of 68.3%.
