Introduction
Parameters
This CNC 4-axis linkage continuous controlled turning center is designed for Semi-finish turning and finish turning shafts and plates as well as milling cylindrical and face.Except the function of turning linearity,oblique line,arc(cylindrical,rotary camber,spherical surface and conic section),straight and taper metric/inch screws,the machine mated SIEMENS 810D system has also the function of drilling radial and axial holes and screws.It is especially suitable for processing complicated and precision plate and shafts.
Adopting 45° slant bed,the longitudinal and transversal guide way adopts high precision rolled guide way couples.The transmission system of the spindle adopts wide varied speed A.C. servo and the main motor drives spindleby multiwedge belt.The transmission of the X and Z axis adopt 1:1 shift,and the machine adopt semi-circled control.Mated with horizontal 12 positions power tool post and proper tools,the machine has wide technology adaptability.
