Double-spindle milling center CH6145-2S

CH6145-2S milling center Max swing diameter over bed: 450mm Max. processing diameter: 300mm Max. processing length: 500mm

1. Overview

lCH6145-2S double spindle milling center is used for finishing the machining process of turning, milling, boring and drilling, tapping of special high precision complex parts in aviation, aerospace, automotive, national defense military industry, the second spindle accurate position realizes the back processing. First and second spindle can realize the synchronous operation to process complex long axis parts, through one-time clamping workpiece to realize the precision process to complex parts.

lThe machine adopts 45 degree postposition inclined bed, transverse and longitudinal guide is high precision roller guide rail pair, the first and second spindle have the C axis function and are high-speed electric spindle. The precision is high and dynamic performance is good, and slippery saddle has the C axis function. The machine has the function of 6 axis four linkage, and through that it adopts German Siemens 840D CNC system to control X, Y, Z, C1, C2, W axis mutual interpolation so that it realizes the altitudinal flexible processing ability.

lThe modeling design of the machine has period feel, and is beautiful and practical, and agreeableness is good. The machine electric parts are reliable. CNC system is AC digital drive, loop closed control, and it has the feathers of reliability, strong ability of anti-interference. The system has the advanced functions of tread pitch error compensation, constant linear speed cutting, fixed cycle, programming as the drawing size directly, DNC communication and so on. Rapid speed of the machine response and good dynamic rigidity can ensure the good quality of the machine.
