The machine adopts initiative moving
principle in the middle of the column with independent intellectual property.
It adopts advanced creepfeed profile grinding technology and the workpieces can
be formed directly from blank.
Features
■Domestic initiative structure
of cross guideways with independent intellectual property
■ High feed sensitivity and processing accuracy of
the guideways of X, Y and Z axes.
■The machine adopts Siemens
802D/810D/840D CNC system. It also has the compensation function of linear
interpolation and arc interpolation.
■High positioning accuracy and
re-positioning accuracy
■Varied profile dressing technology such
as table diamond roller dressing, diamond pen or disc dressing through the
coordinated control of Y and Z axes, continuous dressing of top-mounted diamond
roller (CD).
■High speed ball leadscrews can be
equipped for the longitudinal movement
■Fully-enclosed construction of the
machine grinding area
■Comply with safety standards
