CNC machine center

CNC machining center can be high precision, high efficiency. Machining.

This series of gantry CNC boring and milling (machining center) to all kinds of foundation bed main big, panel, dishes pieces, shell parts, mold, and other varieties precision parts in nc machining. In a clamping workpiece can be high precision, high efficiency continuous finish milling, boring, drilling, reaming, rigid tapping and so on many kinds of process processing. Suitable for aerospace, shipbuilding, power generation, war industry, ChongJi, locomotive, machine tools, textile machinery, printing machinery, mould manufacturing, etc. According to user needs can increase the nc rotary table or the appropriate attachments milling head, realizes to the five surface processing.Spindle box unit with double hydraulic cylinder balancing machine, ensure the smoothness of the spindle box movement.Beam large size cross section design and step guide structure shorten the shaft centerline to below guide distance, enhance the beam bending and torsional rigidity, be helpful for cutting stability.Machine tool bed, column, beam, wagen, spindle box adopts resin sand molding high-strength cast iron and reasonable cloth bar structure, good rigidity and stability.Table drag with large inertia ac servo motor with high quality heavy ball screw and linear guide, the optimization design has good positioning accuracy and steady state response. Active dynamic using wide speed ac servo main motor, equipped with ZF transmission, make main shaft in low speed high torque output, suitable for heavy cutting, high speed constant power suitable for finishing.Spindle is composed of precision machine tool spindle special bearing support, the preloaded after spindle rigidity and rotary precision taste. The oil cooling machine (circulation system) on the main group of cooling, effectively control spindle group temperature rise.There are two main forms optional, a short nose type, suitable for general processing form. Another long nose type, focus on deep cavity machining, such as mould, etc.
