Name:VMC850 vertical machining center

Introduction:

First, the main use:


The machining center of vertical bed type structure, X, Y axis and Z coordinate control, maximum fast transfer speed of 24m/min (Z axis: 15m/min); spindle servo motor drive, power is 5.5/7.5Kw, maximum speed up to 8000rpm; Taiwan imported silver double nut preloading C3 and heavy load ball screw linear rolling guide screw, both ends of the pre stretching mechanism, which greatly eliminates the influence of hot deformation on the precision of the machine tool, machine tool positioning accuracy of + 0.005mm, repeat positioning accuracy of + 0.003mm; imported Taiwan knife, the knife changing capacity 16-24 optional, accurate and reliable, the fastest tool change time less than 2.5 seconds; CNC machine tool the operating system is the customer demand, the machine can achieve all kinds of disc type, plate, shell, cam, mold and other complex parts in a fixture for drilling, milling, boring, reaming, reaming, tapping and other A process, suitable for many varieties, small batch production, for the complex, high precision machining parts can show its superiority; machine tools such as configuration 4 and 5 axis, can achieve high efficiency and high precision automatic machining of complex rotary parts. The machine tool is suitable for aviation, aerospace, military, national defense, automobile, motorcycle, engineering machinery, refrigeration, petrochemical, rolling stock and other industries of small and medium-sized parts of high efficiency, high precision and automatic processing.


Two. Main structural features:


* high rigidity: the bed type machining center structure, composition of machine tool is composed of a base, a sliding seat, table, column and spindle box; the main parts are the basis of the finite element analysis of the structure, reasonable structure, high rigidity;
High speed and high precision. The machine adopts high rigidity spindle unit imported from Taiwan, main material selection of high performance alloy, using NSK special P4 high-speed precision spindle bearings, and use NSK to specify the high speed grease, spindle speed of 8000rpm, the spindle radial runout is less than 0.005/300. Cooling water or spindle can achieve center spindle nose water outlet center, spindle configuration function, can handle some sticky cone off chip and other debris, protect the spindle and handle life.
. X, Y, Z direction feed using C3 double precision ball screw nut of the pre load, large torque and low inertia servo motor through flexible coupling and direct import screw, screw bearing with pre stretching structure can eliminate the transmission backlash and pre compensation machine long time effect of deformation on the accuracy of the operation of heat to ensure the accuracy and repeatability of positioning;
