Title:
UNIVERSAL GRINDER
Document Type and Number:
Japanese Patent JPS5652169
Kind Code:
A
Abstract:
During grinding, a grinding wheel effects movements of solely vertical displacement along a path parallel to a vertical guide rod. The workpiece to be machined is held by a rotatable, but not axially displaceable, chuck secured to a workpiece head. In order that helical relative movements between the workpiece and the grinding wheel may be produced, transmission components and gearing are provided for positively converting the vertical motion of the grinding wheel into rotary motion of the workpiece. For cylindrical and surface grinding, the motion-conversion arrangement may easily be disengaged or dismantled. Thus it is possible with this universal grinding machine to carry out drill grinding, cylindrical grinding, and/or surface grinding on a workpiece which need be chucked only once.
