No.	Inspection Item	Inspection Method	View	Tolerance（mm）	Measured Value（mm）
G1	Levelness Inspection	Place the precision level at 90° on the table surface, aligned with the column in the X or Z direction. Move the table forward and backward (positive T) or move the table left and right (negative T). Read and record the values; the measured data shall be taken as the inspection result.		Accuracy Requirement: Dynamic levelness: 1.5 divisions (single table).
G1	Levelness Inspection	Place the precision level at 90° on the table surface, aligned with the column in the X or Z direction. Move the table left and right (positive T), or move the column forward and backward. Read the values in the reverse T direction; the measured data shall be taken as the inspection result.		Dynamic levelness: 1.5 divisions (Dual tables)
G2	Straightness of X-axis Linear Motion (in the XY Plane)	Place the granite straightedge at the center of the worktable.Mount the dial indicator on the spindle. Move the X-axis and record the readings; the measured data shall be taken as the inspection result.		0.02/500mm
	Straightness of Y-axis Linear Motion (in the XZ Plane)	Place the granite straightedge at the center of the worktable. Mount the dial indicator on the spindle. Move the Y-axis and record the readings; the measured data shall be taken as the inspection result.		0.02/500mm
	Straightness of Z-axis Linear Motion (in the YZ Plane)	Place the marble straightedge in the center of the work area; Mount the dial indicator onto the spindle; move the Z-axis, and the measured reading serves as the inspection value.		0.02/500mm
G3	Table Rotation Accuracy	Mount the dial indicator on the spindle, positioning the needle at the bottom-right corner of the worktable surface to establish the 0° reference point. Rotate the worktable to 90°, 180°, and 270°, and record the readings; these measured values constitute the inspection data. The maximum face runout at any point across these four angles must not exceed 0.015 mm.		0.015/500mm
G4	Radial runout of the Spindle Taper Bore a) Near the spindle nose b) At 300 mm from the spindle nose	Mount the dial indicator on the spindle, positioning the needle at the bottom-right corner of the worktable surface to establish the 0° reference point. Rotate the worktable to 90°, 180°, and 270°, and record the readings; these measured values constitute the inspection data. The maximum face runout at any point across these four angles must not exceed 0.015 mm.		（a）0.007mm （b）0.015mm
G5	Parallelism between the spindle axis and the Z-axis motion: a) In the vertical YZ plane: b) In the horizontal ZX plane:	Mount the dial indicator on the worktable. Position the probe on the end face of the test bar. Move the Z-axis and record the readings; the measured values are taken as result (a). Reposition the probe on the side surface of the test bar. Move the Z-axis and record the readings; the measured values are taken as result (b).		（a） 0.015/300mm （b） 0.015/300mm
G6	360Rotation Accuracy			0.015 mm / 400 mm No low spo exceeding 1 division
G7	Perpendicularity between the Spindle Axis and the X-axis Motion	Mount the dial indicator on the spindle. Move the X-axis and record the readings; the measured data shall be taken as the inspection result.		0.015/500
G8	Parallelism between the Table Surface and the Direction of X-axis Motion			0.02MM
G9	Periodic Axial Runout of the Spindle	Position the dial indicator so that it contacts surface a—the outer edge of the spindle's end face. While the spindle is rotating, determine the maximum difference in the indicator's readings; this constitutes the measured value. Next, position the indicator's probe to contact surface b—the outer circumference of the spindle. Rotate the spindle again and measure the maximum difference in readings; this constitutes the second measurement.		0.005MM
G10	Parallelism between the Table Surface and the Direction of Z-axis Motion：			0.015 mm / 400 mm No low spot exceeding 1 division
G11	Flatness of the Table Surface	For a measurement length of 1000 mm, the tolerance is 0.018 mm; for every additional 1000 mm of worktable length, an additional tolerance of 0.005 mm is permitted. Local tolerance: over a 300 mm span, the measurement deviation is ≤ 0.02 mm.		0.02MM
G12	End Face runout of the Table Working Surface			0.02MM
G13	Height Deviation of Interchangeable Tables	Mount the dial indicator onto the spindle; move the X-axis to take measurements, and record the resulting data as the inspection value.		0.02MM
