Description

Technical Field

[0001] The present invention relates to the technical field of tool grinders, and in particular to a novel five-axis CNC tool grinder. Background Art

[0002] In the field of mechanical processing, CNC tool grinders, as high-precision processing equipment, play a vital role in improving production efficiency and processing quality. However, with the continuous development of industrial technology, traditional CNC tool grinders have been unable to meet the needs of modern complex processing in some aspects, especially when grinding workpieces, which have high requirements for workpiece grinding.

[0003] When grinding a workpiece, current grinders usually use a flushing pipe to spray cleaning fluid to flush the grinding wheel surface during the grinding process. However, during long-term use, due to the generation of some iron chips during grinding, the iron chips will be deposited on the grinding wheel surface under the action of the high temperature of grinding. At the same time, some debris will be stuck on the outer surface of the grinding wheel and difficult to be flushed away by the flushing fluid, resulting in the accumulation of impurities such as metal chips and abrasive residues generated during grinding on the grinding wheel surface. These impurities will reduce the service life and processing quality of the grinding wheel. Therefore, the grinding wheel of the grinder must be cleaned before and after use and after long-term use. If these metal debris are not processed for a long time, the grinding wheel will grind the workpiece mixed with metal debris during the grinding process, resulting in slight scratches on the surface of the workpiece, resulting in poor grinding effect on the surface of the workpiece, and reducing the grinding quality of the grinder. During the grinding process, the current grinder needs to be stopped at regular intervals to clean the grinding wheel, resulting in a long grinding time and poor cleaning effect, which causes the current grinder to have poor grinding efficiency and grinding effect when grinding the workpiece.
