10.9 High-Precision Straightness Specification
The high-precision straightness specification type is a precision actuator with high-level settings of parallelism
and straightness, which is the base and slider travel accuracies. The models are expressed with ST.

The values for the high-precision straightness specification are based on measurement at a temperature of 20
r
3qC using a precision stone surface plate of grade 00 and 6.5 Pm in flatness.
x
The values for the standard specification and high-precision specification are based on measurement at a
temperature of 20 r 3qC using a surface plate of 0.05 mm or less in flatness.
x
The parallelism and the straightness of the chart are the standard value of 1m.
Standard value (mm/m) × stroke (m) will be straightness or flatness of the all stroke.
