Hydraulic handle: beat accuracy: 3 um, 14:25000 turn, suitable for precision machining

Hydraulic the handle of the clamping way is different from the traditional handle system, tighten the pressurized with a bolt, when the bolt tightening will push the piston seal piece of a hydraulic oil pressure inside the handle, the pressure evenly from the circumferential direction is passed to the steel expansion, expansion wall and tool clamping. Can make the system accuracy and repeat precision radial runout error control under 3 microns. Because there is high pressure oil pressure in the handle, when the cutter is clamped, hidden in the oil chamber structure and the existence of the high pressure oil is greatly increased damping structure, which can effectively prevent the vibration of the cutting tool and machine tool spindle. Actual application shows that use of this kind of clamping system not only can improve the machining precision and quality, but also can make the tool in machining exponentially increase the service life.
