dnf手游2017最新公告 www.gzgte.icu Hardinge Sure-Grip Power Chucks are lever-operated, counter-centrifugal and dynamically balanced. This enables you to continually operate your CNC lathe at higher spindle speeds and feed rates with less concern for loss of jaw force normally associated with wedge-style chucks. Our 4", 5", 6", 8", 10" and 12" Sure-Grip Power Chucks mount directly to ANSI A2-4, A2-5, A2-6 and A2-8 spindles, eliminating the added tolerance buildup when using special adapter plates. Sure-Grip Power Chucks come standard with 1.5mm x 60° serrated master jaws designed to ISO specifications. Spindle adapters are required when mounting a large chuck to a small spindle, or when mounting a small chuck to a large spindle. Maintain accuracy while increasing productivity with the Hardinge quick-change chuck. The revolutionary patented top jaw design provides top jaw change with the simple turn of a single locking bolt in less than one minute - much faster than conventional jaws.
