A method of using the apparatus for making ultra-high straightness concentricity ceramic pipe rod according to any one of claims 1 to 8, wherein: the traction plate (9) drives the driving screw rod (631) to rotate through the driver (63), so that the traction rotating rod (92) penetrates through the centerless grinding mechanism (2) and the reducing guide cone (3), at the moment, the dynamic pipe rod supporting guide ring (7) is compressed in front of the traction plate (9), at the moment, the feeding plate (8) slides out of the feeding motion base (6), the pipe rod rough blank penetrates through the dynamic pipe rod supporting guide ring (7) to be fixed to the traction clamp holder (93), at the moment, the feeding plate (8) is reset, and the other end of the pipe rod is fixed with the feeding clamp holder (84); along with the drawing plate (9) drive the stick and stretch, the stick is too thick because the diameter this moment, the stick is longer at this moment, but the bending change that receives the influence of gravity is lower, utilize a plurality of developments stick support guide ring (7) dispersion to support simultaneously, guarantee the stick axial stability of pipe rotation, the stick passes through the quick processing of the thick burr (4) of undergauge with the stick at this moment, detect the processing state of the thick burr (4) of undergauge through tapering detection mechanism (5), make the stick diameter behind the thick burr (4) of undergauge reduce the back, the inside that gets into grinding roller set (21) carries out the secondary grinding, along with the increase of time, the thick footpath stick length of feed plate (8) department centre gripping reduces this moment, the thin footpath stick length of feed plate (9) department increases this moment, developments stick support guide ring (7) receives the slip influence of draw plate (9) this moment, roll adjustment spring (73) developments promote stick support guide ring (7) and reset, the stick carries out the dispersion support to the stick, offset the influence of gravity, the stick of pipe, the frame (84) processing back is sent out in the frame (1), and send the processing back to the stick (1) and accomplish.
