In the process of processing, the height error of the head frame, grinding head and tailstock of the cylindrical grinder will make the tailstock, head frame and center line offset in space to a certain extent. At this time, the workpiece surface will be a hyperboloid.
The center line of the head frame and tailstock of the cylindrical grinder needs to influence the parallelism error of the spindle axis of the grinding head in the horizontal plane on the dimensional accuracy of the workpiece. When the error occurs in the process of operation, the working shape of the grinder of the equipment will be a cone.
In the process of using the grinding head of cylindrical grinder, the perpendicularity error relative to the guide rail of the machine tool has an impact on the machining accuracy. The final result of this error is that the axis of the spindle and the center line of the headstock and tailstock will be offset.
The cross roller rigid guide rail is used in the grinding wheel rack of cylindrical grinder. The semi-automatic feed mechanism of the equipment is realized by its rotary oil cylinder. The tailstock shafting of the equipment has the characteristics of no gap stiffness. The electrical box, hydraulic box and cooling box are separated from the machine tool.
The bearing of grinding wheel spindle of cylindrical grinder is effective to use its conical shaped oil wedge hydrodynamic bearing. In the process of operation, the spindle of grinding wheel still has high bearing stiffness at low speed, and the guide rail of grinding wheel frame adopts cross roller rigid guide rail.
In general, the cylindrical grinder will have grinding indicator and coolant filter to a certain extent, so that the head frame speed of the equipment can have the AC variable frequency stepless speed regulation. The electrical of the whole equipment adopts programmable logic controller, which has the function of self diagnosis when in use.
