Grinding machine used for slender axis-like work-piece

The utility model relates to a grinding machine used for a slender axis-like work-piece. The grinding machine comprises a grinding machine body, an X-axis linear guideway and an X-axis carrying plate, wherein the X-axis carrying plate cooperates with an X screw rod which is arranged on the grinding machine and driven by an X-axis servo motor; the grinding machine further comprises a workbench of a Z-axis linear guideway, which is arranged on the X-axis carrying plate; the workbench cooperates with a Z screw rod which is arranged on the X-axis carrying plate and driven by a Z-axis servo motor; the grinding machine further comprises a head frame at one end part of the workbench for cooperating and a tail frame at the other end part for cooperating; a grinding wheel is connected to a grinding wheel frame support in a cooperating manner; the grinding wheel frame support is connected to a rotating disk; the rotating disk is connected to the rotating disk support of the grinding machine in a locating manner; a grinding wheel is connected to a grinding wheel spindle of the grinding wheel frame in a cooperating manner; and an included angle between the axial line of the grinding wheel spindle and a line of centers of the head frame and the tail frame is 20-30 degrees. The grinding machine used for the slender axis-like work-piece, disclosed by the utility model, has the advantages of reducing a radial force applied to a processed slender axis-like work-piece, thereby reducing deformation and improving grinding precision and grinding efficiency.
