MGK28 series machine tools are a series of vertical composite grinders with high precision and rigidity, and full
closed-loop digital control, which are independently designed and developed by Guangyudacheng. This series of
grinders adopt the patented technology (ZL 2012 0 0036107.8) developed by Guangyudacheng, with reasonable
design and compact structure; while a workpiece is put on a table, multi-procedure grinding can be performed for
the internal hole, outer circle and step or end face in one locating to ensure to achieve much accuracy of the
workpiece. The driving systems of the grinders have good dynamic response characteristics and the actuating
elements have high precision, good reliability and high response speed. The advanced technical level of the
machines have reached the international advanced levels. The machines are widely applied to such important
national economy fields as bearing, wind power equipment, engineering machinery, valves, automobiles, military and
robot industry, etc.
