Wire cutting, how about plastic molds or a square iron, four minutes apart
Then discharge the molybdenum wire on the side of the side, then remember the scale of the worktable, adjust the dial on the handle to zero line, and mark it as zero. Then shake the table handle, the table moves half the size of the workpiece + the radius of the molybdenum wire, which is the center of the direction.
The two sides of the square iron are measured accurately, and then the workpiece is adjusted parallel to the on-line cutting table.
Then, in the other direction, the same operation makes it possible to find the central position of the workpiece.
