1、TIGHT CLAMPING FORCE: Milling collet chuck has tight clamping force and high elasticity for use in machining centers, fine engraving machines and many kinds of engraving machine spindles. 2、HIGH FREQUENCY QUENCHING TREATMENT: Milling collet chuck is quenched by high frequency quenching treatment, good low temperature impact toughness and clamping performance, more stable clamping. 3、EASY TO USE: Milling collet chuck passes through the cartridge stop, milling cutter internal cooling out of water, can directly cool the milling cutter during processing, so that the blade is determined stable. 4、HIGH WEAR AND HEAT RESISTANCE: Milling collet chuck has been grinded, high wear and heat resistance, better fit on outer surface, excellent accuracy. 5、LONGER WORKING TIME: Milling collet is heat treated to avoid deformation and cracking, so it can be used for a longer time.
