When the operator uses the cnc cylindrical grinding machine, there are multiple factors that will affect the processing accuracy, the main factors are the following.

1: The influence of the height of the grinding head, headstock and tailstock on the dimensional accuracy of the workpiece.
The equal height error of the grinding head, headstock and tailstock will cause the center line between the headstock and tailstock and the axis of the grinding wheel to deviate in space, and the surface of the ground workpiece will be a hyperboloid.
2: The influence of the connection line between the center of the headstock and the tailstock on the parallelism error of the spindle axis of the grinding head in the horizontal plane on the dimensional accuracy of the workpiece.
When this error occurs, the shape of the workpiece ground by the cnc cylindrical grinding machine will be a cone, that is, the grinding wheel is ground at an angle, and the surface has a spiral grinding pattern.
3: The influence of the grinding head movement relative to the verticality error of the machine tool guide rail on the machining accuracy.
The final result of this error is that the axis of the spindle is offset from the center line of the headstock and the tailstock. When grinding the end face of the shaft shoulder, it will cause an error in the perpendicularity between the end face of the shaft shoulder and the axis of the workpiece. When grinding the outer circle, the surface roughness will be affected, resulting in a spiral grinding pattern.
The dimensional accuracy of the workpiece is easily affected by the height of the grinding head, headstock, tailstock, etc. The cnc cylindrical grinding machine manufacturer tells you that the height error of these parts will cause the position of the headstock and the main axis to deviate. If it is not corrected, the grinder will grind the workpiece at an angle of an inclined plane. The grinding surface is a conical surface, causing the scrap of the workpiece.
The influence of the parallelism error of the center line on the workpiece grinding accuracy. This effect has a great influence on the dimensional accuracy of the workpiece, especially when the workpiece is processed in the horizontal plane.
Knowing the reasons that affect the precision of the cnc cylindrical grinding machine, the operator can take active preventive measures in a targeted manner, thereby reducing the generation of defective products and improving the overall product quality.
