Feb 06, 2009 Video: Understanding The Role Of L:D Ratio In Micromachining. When milling with tiny tools, changing the length-to-diameter ratio can significantly change the cutting parameters it is possible to achieve. #micromachining. The tool’s length-to-diameter ratio is significant in any milling process. The larger the ratio, the less rigid the setup

  • What Is Length-to-diameter Ratio (L/D)?

    What Is Length-to-diameter Ratio (L/D)?

    Jun 25, 2018 L/D is the ratio of the length of magnetization direction of a magnet (L) to the diameter of the magnetization surface (D). For NdFeB magnets, L/D is of important reference significance for the preliminary judgment of the temperature resistance of the magnet. Under normal circumstances, we recommend an L/D of over 0.5 (preferably≥0.7)

A slug catcher will likely have a different L/D ratio than a separator, or a compressor suction drum, for example. The process requirement will generally dictate whether a vessel
