Characteristics of axial grinding method
The way of grinding is in the category of finishing. Let's share the characteristics of the depressed grinding disc in stock's axial grinding method.
When grinding with an axial grinding method, the depressed grinding disc in stock rotates and feeds radially, the workpiece rotates at a low speed and moves in a straight line reciprocating with the worktable. When each axial stroke or the workpiece reciprocating stroke end, the grinding wheel makes a radial feed according to the required grinding depth, and the grinding allowance must be ground in many reciprocating strokes. At the two ends of the workpiece, the grinding wheel must exceed the length of the ends of the workpiece.
(1) The whole width of the grinding wheel depends on the surface division. The edge angle of the end face of the depressed grinding disc in stock plays a major role in cutting, and it is responsible for removing most of the remaining parts of the workpiece.
(2) The grinding quality is good because most of the grinding grains of the grinding wheel bear the role of grinding. The grinding depth is small, the radial cutting force is small, the grinding temperature is low, and the "grinding" around the depressed grinding disc in stock. Because of its good function, the workpiece has high dimensional accuracy and small surface roughness. If the grinding time is properly increased, the machining quality will be further improved.
(3) Grinding efficiency is low because the grinding depth is small, the workpiece can be ground many times by running the tool, and the machine has a long time, so the production efficiency is low.
(4) the scope of application is suitable for grinding external workpiece whose length is larger than the width of the depressed grinding disc in stock; it is especially suitable for grinding long shaft.
