Heavy cutting series of disc parts CNC lathe CN-SP70D,CN-SP70Z
Main performance
1.Max.swing diam. Of the workpiece 730mm
2.Max.length of the workpiece:460mm or 800mm
3.Spindle bore 105mm
Introduction
1.Heavy cutting series of disc parts(without tail seat)
2.Z axis of the machine tool adopts broaden double triangle sliding rail,guide rail width 550, ball screw of Z axis in the middle,foots of the lathe are integral foots,ensure the machine has enough rigidity and accuracy stability.
3.Front box adopts independent spindle structure,choose servo motor drive,low noise,big cutting power.there is an optional with automatic gear shift in the spindle box,effective for heavy cutting torque.
4.Z,X guide are through hardening processing,machine adopts the automatic centralized lubrication,guide rail uses the fully closed structure,raise the service life of the machine tool largely.
5.This heavy duty lathe is specially suitable for processing plates and set of parts , the accuracy of CNC lathe machining is higher than traditional flat rail one and processing high precision and good stable accuracy.
