Introduction
Parameters
This CNC 3-axis continuous controlled turning center is desighed 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 with advanced CNC system has also the function of milling cylindrical and face,as well as 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 machine is easily operation.The longitudinal and transversal guide way adopt high precision rolled guide wqy couples so as to improve the responding speed and life of the machine.The transmission system of the spindle adopts wide varied speed A.C. servo. and the main main motor drives spindle by multi-wedge belt,so the smooth of the transmission of the X and Z axis adopt 1:1 shift so as to improve the rigidity and the responding speed of the machine,the machine adopt entire closed encircled control,so all the accuracy of the machine have been improved greatly.Mated with 12 position power tool-pest and proper tools,the machine has a wide technology adaptability,and reducing the auxiliary labor in the operation.
Mated with A.C.digital driven CNC system,entire closed encircled control,the machine has a strong ability to resistant disturb,and the CNC system has the advanced function of leadscrew error compensation,constant line turning,firmed cycle,programming the data directly on the drawings,DNC communication etc.
