TECHNICAL FIELD

[0002] Numerical control tools are tools used for cutting processing in mechanical manufacturing, also known as cutting tools. Broadly speaking, cutting tools include not only tools but also grinding tools; at the same time, "numerical control tools" include not only cutting blades but also tool shanks and tool handles and other accessories.

[0003] The existing reference announcement for number is CN203282276U Chinese invention patent, which discloses an automatic calibration device of numerical control machine tool. When the device works, first, the action program of the tool is introduced or directly input into the control device, and the machined plate is placed on the positioning plate. When the through hole of the machined plate corresponds to the positioning hole of the positioning plate, the photoelectric detection switch transmits the signal to the control device, and the control device starts the tool to process the machined plate. Compared with the manual alignment device in the existing processing equipment, the device has the characteristics of accurate control, high processing precision and simple operation due to the use of double photoelectric switch alignment structure.
