(3) milling cutter shank: min FMB face mill holder Metric and Inch FMA face mill holder, double extension rods, metric and imperial distinction is the most direct aperture is not the decimal metric system, equal diameter extension rod, and Imperial is a decimal, are used to connect face milling cutter. Model representation method: BT40-FMB22-100L, FMB22 corresponding face mill aperture must be 22, BT40-FMA25.4-90L, FMB25.4 corresponding face mill aperture must be 25.4 Inch . If the slope is longer handle sub-thick shank and thin stalk. NC knife handle measuring instruments production, extension rod, the main purpose is to ensure high quality cutting, high precision, shape and structure of complex CNC tool holders. Common meter are: 1. Germany Zoller's Saturn series CCD NC knife handle presetter 2.Schenck company TooldyneSV CNC tool holders Balancing detector addition, the German BLUM firm and non-contact in England RENISHAW company CNC . Shank Detector: 1 with a jet apparatus capable CNC grinding process, so that the detection precision CNC tool holders and set tool length, radius and runout; 2 but also to monitor the tool edge shape error and. breakage; 3. be able to measure and compensate for the tool relative positional error due to temperature changes, improve tool holders precision CNC grinding machine.
