Title:
GRINDING APPARATUS AND METHOD OF MANUFACTURING RARE EARTH-BASED SINTERED MAGNET
Document Type and Number:
Japanese Patent JP2023144719
Kind Code:
A
Abstract:
To improve dimensional accuracy of grinding by increasing the positioning accuracy of a workpiece during grinding.SOLUTION: A grinding apparatus includes: a grinding wheel supported so as to be rotatable about a central axis; and a support table having a sliding surface for slidably supporting a workpiece, the support table being disposed so as to sandwich the workpiece between the sliding surface and an outer peripheral surface of the grinding wheel. The outer peripheral surface of the grinding wheel has an arch-shaped curve in a cross section taken along a plane including the central axis. The support table has a plurality of slits formed in the sliding surface and two guides extending in parallel on both sides of the workpiece positioned on the sliding surface, and the plurality of slits are inclined with respect to a direction in which the guides extend.SELECTED DRAWING: Figure 1
