what is surface grinding & reciprocating grinding?

what is surface grinding & reciprocating grinding?

According to DIN 8589-11, surface grinding is classified as a face-peripheral-longitudinal grinding process, which is widely used in industrial applications to produce flat surfaces. According to the position of the grinding wheel in relation to the surface to be processed, this process is divided into:

Here, cup wheels or segment heads equipped with grinding segments take over the machining of the work pieces. With these grinding processes, the work pieces can be processed both in reciprocating grinding and creep feed grinding. processed both in reciprocating grinding and creep feed grinding.

In reciprocating grinding, the grinding wheel travels back and forth over the work piece at high table speeds between 12 - 60 m/min and small in-feeds of 1m to 100m. The investment in machines is relatively low, making it a cost-effective method for smaller batch sizes.Why is this grinding process a cost-effective method?

The grinding forces Ft and Fn and the grinding temperatures are much lower than with creep feed grinding, which almost eliminates the risk of edge zone influence. The contact area is much smaller when reciprocating grinding and thus the risk of so-called "grinding burn" is minimized

generation of rotationally symmetric surfaces by infeed grinding with a rotary table and a cup wheel - sciencedirect

generation of rotationally symmetric surfaces by infeed grinding with a rotary table and a cup wheel - sciencedirect

In infeed grinding with a rotary table and a cup wheel, the wheel radius, the center distance between the rotary table and the cup wheel, the wheel inclination angle and the rotary table direction angle can be actively chosen. This makes it capable of generating a rich family of rotationally symmetric surface shapes with high accuracy, high surface finish and high surface integrity in a cost effective way. However, its application has long been confined to silicon wafers flattening and thinning. In this study, the theoretical basis for the rotationally symmetric surface generation by this grinding method was developed. The possible shape types of the generating curves and the substantial influence of the machine configuration parameters on their shape characteristics were analyzed. It was found that, besides flat surface, it can be used to generate straight conical surface, convex conical surface, concave conical surface, convex to concave conical surface, concave to convex conical surface, convex to concave to convex conical surface and concave to convex to concave conical surface.

The theoretical basis for the rotationally symmetric surface generation is developed. The generating curves of the cup wheel are classified into 7 types. A rich family of rotationally symmetric surfaces can be formed by this method.
