GB/T 36917 "Cutting tools for dental laboratory" consists of four parts. --- Part 1.Steel cutting tools for laboratory use. The purpose is to standardize the dimensions and other requirements of steel cutting tools. --- Part 2.Carbide cutting tools for laboratory use. The purpose is to standardize the various dimensions and other aspects of carbide cutting tools Require. --- Part 3.Carbide cutting tools for milling machines. The purpose is to standardize the various dimensions and other aspects of cemented carbide cutting tools for milling machines. a requirement. --- Part 4.Micro carbide cutting tools for laboratory use. The purpose is to standardize the dimensions and other aspects of miniature carbide cutting tools various requirements. GB/T 36917 is divided into the above four parts according to the differences in materials, connecting equipment and dimensions of cutting tools for laboratory use. This document is one of a series of standards for dental rotary instruments. Dental laboratory cutting tools Part 3.Carbide cutting tools for milling machines1 ScopeThis document specifies the dimensions and other requirements of 3 commonly used carbide cutting tools for milling machines. These three carbide cutting tools are dental The most important cutting tools used in laboratory milling machines. This document applies to 3 types of carbide cutting tools for milling machines mainly used in laboratories. This document does not apply to other characteristic cutting tools for laboratory use (eg. helical cutting edge, cross cutting edge). Cutting tools for CAD/CAM systems are not covered by this document.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
