Ball electric-spark rounding machine tool and process

Abstract

The invention relates to a ball electric-spark rounding machine tool and process. The machine tool comprises a base, wherein a workbench and a rounding mechanism are arranged on the base, the workbench is rotationally connected with the base through a supporting assembly, the rounding mechanism comprises a grinding wheel polishing assembly and a discharging assembly, and the grinding wheel polishing assembly comprises a grinding wheel and a first motor used for driving the grinding wheel to rotate; and the discharging assembly comprises an electrode and a discharging power source electrically connected with the electrode, and the grinding wheel and the electrode are both located above the workbench. According to the machine tool and the process, burrs on the surfaces of balls are removed in an electric spark machining mode according to a discharge rule that a strong discharge phenomenon is generated on the sharp part of a workpiece, the mode has strong selectivity on the machined surfaces of the balls, so that a better deburring effect can be obtained, and the roundness of the balls and the machining quality of the balls can be effectively improved.

Description

technical field [0001] The invention relates to the field of bearing manufacturing, in particular to a ball electric spark rounding machine tool and technology. Background technique [0002] In the production and processing of bearing balls, there is a deburring process that requires the roundness of the balls to be guaranteed. The existing deburring methods for bearing balls usually use smooth grinding or filing processes, that is, rough machining and finishing basically use The same process or even the same tool, this method is not only time-consuming and labor-intensive, but also increases the burden on the workers, and the loss of the tool is relatively large, requiring additional costs to repair or replace the tool, and also affects the processing efficiency of the bearing ball. Contents of the invention [0003] In view of this, in order to solve the above technical problems, the present invention provides a ball electric spark rounding machine tool and process. [...
