With the development of technology and the improvement of performance and reliability of CNC system, the price becomes more reasonable, which makes the price comparison between centerless grinder and ordinary grinder acceptable to the majority of users. At the same time, with the improvement of advanced manufacturing and automation technology in production, the use of surface grinder will be more and more widely.
Parts are the accessories of assembly equipment, so the dimensional accuracy requirements are very high. If there is deviation, it will be impossible to install and use. Therefore, the processing accuracy of cylindrical grinder must be accurate. But cylindrical grinder is a mechanical processing equipment, and there will be deviation. What factors will affect the processing accuracy of grinder? Let Hangzhou grinder tell you:
1. The influence of the size of the workpiece, the height of the grinding head and the center of the grinder.
In this case, you should adjust the height error of the grinding head, head frame and tailstock in centerless grinder to make the center line of head frame and tailstock deviate from the axis of the grinding wheel spindle in space. At this time, the workpiece surface will be a hyperboloid.
2. The influence of the parallelism error of the grinding head spindle axis in the horizontal plane on the workpiece size accuracy caused by the connecting line between the head frame and tailstock center.
When the grinding wheel grinds the workpiece into a cone shape, that is, when the grinding wheel grinds the workpiece into a cone shape, the error occurs.
3. The influence of Perpendicularity Error of centerless grinder head movement relative to machine tool guide rail on machining accuracy is analyzed.
The final result of this error is that the axis of the spindle is offset from the center line of the headstock and tailstock. When grinding the end face of the shaft shoulder, the perpendicularity error between the end face of the shaft shoulder and the axis of the workpiece will be caused. When the centerless grinder grinds the outer circle, it will affect the surface roughness and produce spiral wear lines.
