THIN-SECTION MANUFACTURING METHOD AND THIN-SECTION MANUFACTURING DEVICE

摘要

A thin-section preparation method includes: a first rough cutting step of performing rough cutting of the embedded block (B) in one end region (D1) of a first cutting blade (121a) along a blade edge direction, in a one-blade set state where entire of the first cutting blade (121a) of the cutting blade (21) is held by a holder (22) in the blade edge direction; a first main cutting step of performing main cutting of the embedded block (B) which has been performed rough cutting in another end region (D2) of the first cutting blade (121a) along the blade edge direction in the one-blade set state; a second rough cutting step of performing rough cutting of the embedded block (B) in the other end region (D2) of the first cutting blade (121a), in a two-blade set state where the other end region (D2) of the first cutting blade (121a) and one end region (D1) of a second cutting blade (121b) of the cutting blade (21) along the blade edge direction are held by the holder (22); and a second main cutting step of performing main cutting of the embedded block (B) in the one end region (D1) of the second cutting blade (121b) in the two-blade set state.
