secondly, after the second surface (25) is finely ground to obtain corresponding allowance, detecting the verticality of the first surface (24), the third surface (26) and the second surface (25) by using a three-coordinate measuring instrument, and if the verticality is within 0.005mm, directly finely grinding the fourth surface (27) according to the size requirement of a drawing; if the verticality exceeds 0.005mm, inserting a 0.005mm gasket (3) between the bump (9) and the end face of the machine base (1) through an inserting part (7) according to actual detection data, then sequentially penetrating through a through hole II (19), a through hole I (11) and a through hole (14) through bolts (12) to be in threaded connection with a threaded hole (13) on the machine base (1), positioning the gasket (3), then respectively screwing the other bolts (12), positioning the electric spindle (2), and grinding the allowance of a fourth surface (27), and after detecting that the verticality of the fourth surface (27) is smaller than 0.005mm by using a three-coordinate measuring instrument, finely grinding the second surface (25) until the second surface is qualified;
thirdly, finely grinding the fifth surface (28) and the sixth surface (29) by adopting the method in the second step;
and seventhly, detecting and accepting the finely ground hexahedron by using a three-coordinate measuring instrument and issuing a detection report.
