PROCESSING DEVICE

To surely grip an appropriate exchange period of a sucking cup of a transfer mechanism by simply and surely performing diagnosis of deterioration (normal state or abnormal state) of the sucking cup.SOLUTION: In a cutting device (processing device) 1 having a chuck table 40, processing means 50, a transfer mechanism 70, and a diagnosis part 100, the transfer mechanism 70 comprises: a transfer pad 74 having a sucking cup 75 with an elastic force; and a lifting mechanism 71 that lifts the transfer pad 74. The lifting mechanism 71 comprises: a ball screw 714; a motor 715; and a load current value detection part 720 that detects a load current value of the motor 715. The diagnosis part 100 makes the sucking cup 75 communicate with a sucking source 78 by pressing the sucking cup 75 against a contact surface, and diagnoses that the sucking cup 75 is in a normal state in the case where the load current value detected by the load current value detection part 720 is a predetermined threshold value or larger when lifting up the transfer pad 74 on a predetermined distance Δh from the contact surface by operating the lifting mechanism 71, or that the sucking cup 75 is in an abnormal state in the case where it does not reach the threshold value.SELECTED DRAWING: Figure 2 【課題】搬送機構の吸盤の劣化（正常か異常か）を簡単且つ確実に診断して吸盤の適正な交換時期を正確に把握すること。【解決手段】チャックテーブル４０と、加工手段５０と、搬送機構７０と、診断部１００とを備える切削装置（加工装置）１において、搬送機構７０は、弾性力のある吸盤７５を備える搬送パッド７４と、該搬送パッド７４を昇降させる昇降機構７１とを備え、該昇降機構７１は、ボールネジ７１４と、モータ７１５と、該モータ７１５の負荷電流値を検出する負荷電流値検知部７２０と、を備え、診断部１００は、吸盤７５を接触面に押し当て該吸盤７５を吸引源７８に連通させ、昇降機構７１を作動させて接触面から所定の距離Δｈ上に搬送パッド７４を上昇させる際に負荷電流値検知部７２０が検知する負荷電流値が予め設定した閾値以上の場合には吸盤７５が正常、該閾値に達しなかった場合には吸盤７５が異常であると診断する。【選択図】図２
