The early 1990s, Germany began the safety of high-speed milling technology research and developed a draft standard "high-speed cutter safety requirements" din6589-1, provides high-speed cutter standard test methods and failure in technology the proposed high-speed cutter design, manufacture and use of guidance, provides a unified security test. The draft standard has become a national high-speed cutter safety guidance documents.

In the form of high-speed cutter and test methods fail-safe

The draft standard specifies a high-speed cutting speed limits, after exceeding the speed centrifugal force will be the main payload cutter, must be security technology. In high-speed cutting tool diameter range diagram, the area above the curve for the standard high-speed cutting cutter must pass safety inspection scope: the diameter of a single piece d1≤32mm tool (in whole or welding tool), its cutting speed than 10000m / mm for high-speed cutting range; the diameter d1> 32mm machine folder fabricated tools, ranging from high-speed cutting area above the line bc.
