Doosan DVF5000 - Spindle Centerline and X-axis Movement Squareness (X-Z Plane)

51
6. Machine Accuracy Measurement and Adjustment
6.6 X-Y axis cross-squareness
1) Measurement
Place a square ruler lying on the table top, set the indicator at both ends while moving
the indicator in the X-axis direction(
ⓐ－ⓑ), and adjust the X-axis direction parallelism
by hitting the higher side with a driver handle, etc. Measure the parallelism of the
square’s Y axis direction (ⓒ－ⓓ
) and use the biggest difference as the measured value.
▶ Measurement position : X- and Y-axes direction of the square ruler with zero
setting(ⓑ-ⓐ, ⓒ-ⓓ)
▶ Tolerance : 0.010mm / 300mm
2) Measurement
In general, it is very unlikely that axial squareness deformations will occur in L / M guide
machines, but if orthogonally deformed due to severe collision, rearrangement of the / M
guide block is required through the revision of squareness.
