Abstract
The article presents the results of experimental research for grinding of corundum ceramic with the use of an spherical diamond head. Article shows the influence of tilt angle and feed on roughness parameters. Authors also described influence of tilt angle and thickness of the grinding layer on effective cutting speed.
Highlights
The article presents the results of experimental research for grinding of corundum ceramic with the use of an spherical diamond head
There has been a clear increase in the demand for elements made of corundum ceramics with complex geometry
The grinding tests were carried out on a pre-baked corundum frame. The purpose of these tests was to determine the influence of the tilt angle β of the grinding wheel axis on the roughness parameters Ra and Rz at different values of feed speed vf
Summary
The article presents the results of experimental research for grinding of corundum ceramic with the use of an spherical diamond head. The shaping of elements with complex geometry from sintered corundum and zirconium ceramics takes place only on multi-axis machining centers in the process of diamond grinding, spindle grinding wheels with small diameters – on the order of a few millimeters [4, 6]. The use of such small tools requires high speeds of the tool spindle in order to achieve the right grinding speed. The grinding tests were carried out on a pre-baked corundum frame The purpose of these tests was to determine the influence of the tilt angle β of the grinding wheel axis on the roughness parameters Ra and Rz at different values of feed speed vf.
