PROBLEM TO BE SOLVED: To provide a chamfering device capable of measuring machining dimensions for all the machined workpieces without or almost without increasing cycle time and thus achieving higher machining accuracy without reducing productivity, in a chamfering device which machines a side of a hard brittle sheet such as a glass substrate for a display panel. SOLUTION: An upstream side upper camera 5a for looking at an upper surface of a workpiece at both sides thereof is disposed in an upstream side of a sending direction of a table 2 with respect to a tool 3 at both sides in width direction. Also, a downstream side upper camera 5b for looking at an upper surface of a workpiece 1 at both sides thereof in a downstream side of a table sending direction of the tool 3 and a downstream lower camera 6b for looking at a lower surface of the workpiece at both sides thereof in the downstream side are provided. Chamfering is performed while the table is moved and fed, and the chamfering dimensions are measured by the downstream side cameras 5b and 6b immediately following the chamfering.
