A numerically-controlled machine tool comprises a chuck (1), a workbench (2), a cutter (3), and a control unit (4). The chuck (1) and the control unit (4) are fixed on the workbench (2). The chuck (1) is used for clamping a workpiece (200). The cutter (3) is driven by the control unit (4) to perform movement. The numerically-controlled machine tool also comprises a photographing device. The photographing device comprises a lens (51) and a photographing body (52) connected to the lens (51). The lens (51) is disposed at a connection position of the cutter (3) and the control unit (4), and is aligned with a direction in which the cutter (3) processes a workpiece. By arranging a photographing device in the numerically-controlled machine tool, a workpiece processing procedure can be observed from the rear side of the cutter more accurately in real time, and the probability of the fracture of the cutter colliding with the workpiece is reduced. |
