Zusammenfassung: | To provide a cutting device which can prevent the occurrence of a processing failure due to erroneous attachment of a cutting blade.SOLUTION: A cutting device for cutting a workpiece comprises: a chuck table which holds the workpiece on a holding surface; a cutting unit which includes a spindle in which a cutting blade for cutting the workpiece held on the holding surface is attached to the tip part; an imaging unit which images the outer peripheral part of the cutting blade attached to the cutting unit; and a determination unit which determines the orientation of the cutting blade. A plurality of protrusions including a first surface that feeds cutting chips generated when cutting the workpiece by the cutting blade and a second surface that is connected to the first surface are provided on the outer peripheral part of the cutting blade. The determination unit determines the orientation of the cutting blade attached to the cutting unit on the basis of an image of the protrusions acquired by the imaging unit.SELECTED DRAWING: Figure 1
【課題】切削ブレードの誤装着による加工不良の発生を防止することが可能な切削装置を提供する。【解決手段】被加工物を切削する切削装置であって、被加工物を保持面で保持するチャックテーブルと、保持面で保持された被加工物を切削する切削ブレードが先端部に装着されるスピンドルを有する切削ユニットと、切削ユニットに装着された切削ブレードの外周部を撮像する撮像ユニットと、切削ブレードの向きを判定する判定部と、を備え、切削ブレードの外周部には、切削ブレードで被加工物を切削する際に発生する切削屑を送り出す第1面と、第1面に接続された第2面とを含む複数の突起部が設けられ、判定部は、撮像ユニットによって取得された突起部の画像に基づいて、切削ユニットに装着された切削ブレードの向きを判定する。【選択図】図1 |
