[Problem to be solved] However, this cutting object
When cutting an object , of course, there is the generation of chips when cutting,
Further, it is necessary to apply a processing oil to the cutting tool or the cut product in order to prevent a component edge that grows on the cutting teeth during cutting. Removal of these attached chips and oils must be blown off by air pressure or removed by washing. Further, there is a problem that a cutting margin is required for cutting with a blade, and waste of material is caused. In particular, the flat porous aluminum tube 1 to be cut according to the present invention is used as a heat radiating portion of a compression heat exchanger of a vehicle or the like. As shown in FIG. 1, the upper and lower pieces 2 and 3 having a predetermined thickness (0.5 mm) and arc pieces 4 at both ends of the upper and lower pieces 2 and 3 are formed in a narrow space. The upper and lower pieces 2 and 3 are vertically formed with a plurality of partition pieces 5 at predetermined intervals to form a plurality of holes 6 along the longitudinal direction. The width H of the tube is approximately 18 mm and the thickness T is approximately 2 mm
Since it is a necessary condition that there is no adhesion of dirt, chips and the like on the inner diameter portion of the hole 6, the conventional cutting method cannot be cut at all.
