Embodiment Construction
[0017] The milling processing method of graphene-aluminum matrix composite material of the present invention adopts PCD milling cutter to process, and the rotating speed of described PCD milling cutter is 10000~18000r / min, and feed rate is 0.05~0.15mm / r, and cutting depth is 0.1 ~0.3mm, the radial circular runout, end surface circular runout and axial movement of the machine tool spindle are less than 0.02mm.
[0018] The PCD milling cutter is the existing cutter head made of polycrystalline diamond. Compared with the ultrafine tungsten steel milling cutter and the cubic boron carbide milling cutter, it has high hardness, high thermal conductivity, low thermal expansion coefficient, high The advantages of elastic modulus, low coefficient of friction and extremely sharp blades have been tested. During the processing of graphene-aluminum matrix composites, chips are not easy to stick to the tip of the blade to form built-up edge. When cutting workpieces for a long time The dimen...
