The invention provides a numerical-control external cylindrical grinding machine, and belongs to the technical field of machine tools. By the numerical-control external cylindrical grinding machine, problems of low machining precision and machining efficiency of an existing external cylindrical grinding machine can be solved. The numerical-control external cylindrical grinding machine comprises a machine body and a headstock. The headstock is arranged on the machine body, a chuck is arranged on the headstock, first servo feed shafts are arranged between the headstock and the machine body, a coarse grinding head and an accurate grinding head which are respectively positioned on two sides of the front of the headstock are further arranged on the machine body, and the axis of the accurate grinding head is parallel to the axis of the headstock; the axis of the coarse grinding head is intersected with the axis of the headstock, a second servo feed shaft is arranged between the accurate grinding head and the machine body, a third servo feed shaft is arranged between the coarse grinding head and the machine body, an automatic feeding structure and an auxiliary supporting structure are further arranged on the machine body, the work efficiency can be improved by the aid of the automatic feeding structure, and the machining precision can be improved by the aid of the auxiliary supporting structure for supporting workpieces. The numerical-control external cylindrical grinding machine has the advantages of high machining precision, high machining efficiency and the like.
Description
technical field [0001] The invention belongs to the technical field of machine tools, and relates to a cylindrical grinding machine, in particular to a numerically controlled cylindrical grinding machine. Background technique [0002] Due to the poor rigidity of slender shaft parts, vibration and deformation are easy to occur during processing, and it is difficult to ensure the geometric accuracy and surface roughness of the workpiece. Fine grinding is used to eliminate geometric errors and chatter marks caused by workpiece cutting stress and deformation. Traditional cylindrical grinding machines have cumbersome processing steps for processing slender parts, low processing efficiency, and very high requirements for operators, especially when grinding stepped slender shaft parts, repeated loading and unloading will also cause concentricity errors of the workpiece. Surface finish is also not guaranteed. Contents of the invention [0003] The object of the present invention...
