Problems solved by technology

[0004] In the structure of the grinding machine described in Japanese Patent Application Laid-Open No. 2011-189433, when grinding objects to be ground, except for the main shaft used to move the grinding wheel holder between a group of objects to be ground (left and right directions in FIG. 3 ), In addition to the inter-moving mechanism, a tool-feed moving mechanism for moving the grinding wheel head in the tool-feed direction (up and down in Fig. 4) is also used. There are many moving axes, which complicates the device configuration and process control, and tends to increase the cost.

Abstract

A grinding machine includes a wheel spindle stock in which a wheel spindle is rotatably provided. The wheel spindle moves between first and second spindles so that a third rotation axis of the wheel spindle moves in the direction perpendicular to first and second rotation axes on an XZ plane extending through the first and second rotation axes. The grinding wheel that is held by the wheel spindle grinds a first workpiece as the wheel spindle stock moves toward a first headstock, and grinds a second workpiece as the wheel spindle stock moves toward a second headstock.

Description

technical field [0001] This application claims the priority of Japanese Patent Application No. 2014-238298 filed on November 26, 2014, and uses the entire content including the specification, drawings, and abstract of the specification here. [0002] The present invention relates to a grinding machine and a grinding method for grinding objects to be ground. Background technique [0003] For example, Japanese Patent Application Laid-Open No. 2011-189433 describes that in order to improve the efficiency of grinding processing, a plurality of sets of two holding parts for the object to be ground are provided on the outer peripheral edge of the rotary table, and two grinding wheels of different shapes Grinding machine for grinding a group of objects to be ground separately. [0004] In the structure of the grinding machine described in Japanese Patent Application Laid-Open No. 2011-189433, when grinding objects to be ground, except for the main shaft used to move the grinding w...
