<p>PROBLEM TO BE SOLVED: To provide a drainage mechanism of a processing device in which selection of reuse or dispose of processing water is possible.SOLUTION: A cutting device comprises a chuck table, cutting means which cuts a workpiece, a drain pipe 30 and a drainage mechanism 40. The drain pipe 30 exhausts processing water. The drainage mechanism 40 exhausts the processing water exhausted from the drain pipe 30 to a first drain channel 41 or a second drain channel 42 depending on suitable selection. The drainage mechanism 40 comprises first water-receiving means 51, second water-receiving means 52 and guiding means 44. The first water-receiving means 51 is positioned below an exhaust port 31 of the drain pipe 30, receives the processing water from a first receiving port 51a and exhausts it to the first drain channel 41. The second water-receiving means 52 is positioned below an exhaust port 31 of the drain pipe 30, receives the processing water from a second receiving port 52a and exhausts it to the second drain channel 42. The guiding means 44 guides the processing water to the first water-receiving means 51 or the second water-receiving means 52.</p> |
