T/WLJC 21-2019 CNC tool grinder
Basic Information
Scope
Scope: This standard specifies the manufacturing and acceptance requirements for CNC tool grinding machines, including geometric accuracy, positional accuracy, and operational accuracy, as well as the inspection methods. This standard applies to CNC tool grinding machines designed for grinding drills, end mills, or taps with a maximum diameter of 4 mm to 14 mm. Main technical content: The scope of application of the standard is defined as CNC tool grinding machines with a maximum grinding diameter of 4 mm to 14 mm. By formulating this standard, the following main issues are addressed: (1) There is a lack of enterprise-level or higher product standards for CNC tool grinding machines, and the product standards of various enterprises are not publicly available. This leaves users of CNC tool grinding machines without advanced standards to refer to when comparing the advantages and disadvantages of commercially available products. (2) The accuracy inspection methods and judgment criteria for CNC tool grinding machines. The accuracy requirements proposed in the standard represent the advanced technical level in China.
