CAM GRINDING MACHINE FOR PROCESSING SURFACE OF CAM ACCORDING TO DESIRED ROUGHNESS BY GRINDING INNER BORE AND OUTER BORE OF CAM

摘要

PURPOSE: A cam grinding machine is provided to obtain the surface roughness corresponding to various machine tools by reciprocating a driving unit and a grinding unit along an X-axis and a Y-axis and grinding the outer bore and the inner bore of the cam with the outer grinding wheel and the inner grinding wheel. CONSTITUTION: A cam grinding machine(1) is composed of a housing, a driving unit installed in the housing to process the outer bore and the inner bore of the cam, and a control unit formed in the housing to control the driving unit. The driving unit comprises a fixing unit rotating the cam at regular speed and a grinding unit(340) grinding the outer bore and the inner bore of the cam fastened to the fixing unit. The fixing unit has first and second fixing units fastening the cam, a fixing unit moving linear(308) fixing the first and second fixing unit by sliding, an X-axis moving plate(306) fastening the fixing unit moving linear and moving along the X-axis by the control unit, and an X-axis base(304) combined with the X-axis moving plate by sliding. The grinding unit comprises a Y-axis base(342) formed perpendicularly to the X-axis base in the upper part of the housing, a Y-axis moving plate(344) combined with the Y-axis base by sliding, an outer bore grinding wheel(364) grinding the cam fastened in the first fixing unit, an outer bore spindle motor(346) transmitting power to the outer bore grinding wheel, an inner bore grinding wheel(358) grinding the inner bore of the cam, and an inner bore spindle motor(356).
