Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a numerically controlled machine tool with high safety performance and high integration degree. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, represent them in coded numbers, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0003] CNC machine tools have better solved the problems of complex, precise, small-batch, and multi-variety parts processing. They are flexible, high-efficiency automated machine tools, represent the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0004] The invention patent with patent number CN 103317354 B discloses a CNC machine tool, which includes a bed, a workbench, a platform, a support arm, a crossbeam and a slide. The middle of the bed is an inwardly concave inclined surface, and both sides of the bed are guide rail mounting seats higher than the inclined surface. Linear guide rails are installed on the guide rail mounting seats, and oil grooves are provided on the sides of the guide rail mounting seats, and longitudinal water grooves are provided on the sides of the oil grooves. A slag discharge groove is provided on the sides of the longitudinal water grooves, and the oil grooves and the longitudinal water grooves are separated by dividing ribs; a transverse water groove is provided on the bed at the upper end of the inclined surface, and an oil drain port is provided on the bed at the lower end of the inclined surface; guide rail mounting seats are provided on the front and rear vertical surfaces of the crossbeam, and linear guide rails are installed on the guide rail mounting seats.

[0005] Existing CNC machine tools have some shortcomings when in use. First, when the drill bit processes parts, it will produce iron wires, which will remain on the work surface. The existing technology requires manual cleaning. Since the iron wires are relatively sharp, it is easy to cut your fingers if you clean them directly by hand, which is very unsafe. Moreover, the iron wires will affect the processing of subsequent workpieces. Secondly, the iron wires and other waste materials generated by processing take up a lot of space, which is very troublesome to clean, and will reduce the efficiency of workpiece processing. Existing CNC machine tools generally use separate and independent processes when cleaning and collecting iron wires. In addition, collecting iron wires takes up a lot of space, and the collected iron wires cannot be processed on site, resulting in low efficiency of collection and cleaning, and the integration level of the machine tool is not high, which affects the processing efficiency.
