It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
A chip breaking method for solving long aluminum chips generated by machining comprises the following steps:
step one, cutting and machining a valve gasket sinking table:
as shown in figure 1, the machining process is changed on the machining program of the machine tool, the original method adopts a single cutting parameter to directly machine to the final size, the three times of cutting are changed to the machining depth, the feeding speed is changed, namely the feeding amount is less than or equal to 0.1mm/Z, at least 1 rotation pause is carried out during the cutting of each layer of depth, the aluminum scraps are thinned, and the aluminum scraps are naturally easy to break;
the method comprises the following specific steps:
the cutter moves quickly to a safe distance of contacting the workpiece;
the cutter rotates at a set rotating speed, and a first depth is processed at a set feeding speed;
the cutter stops and rotates 1 revolution to break chips;
then processing a second depth at a set speed of progress;
