1 XW-250Shape and position error measuring instrumentCharacteristics:
（1）Shape and position error measuring instrumentWith the support and positioning, equipped with data acquisition and processing equipment, it can measure eight positional errors of shaft and disc sleeve parts, including roundness, cylindricity, coaxiality, axial straightness, axial straightness, axial parallelism, circular runout (radial, end face, oblique), and radial total runout.

(2) Positional errorMeasuring instrumentThe pair used is made of Mohs 4 hard alloy and has been precision machined to improve its roundness accuracy, thusMeasuring instrumentHas high radial rotation accuracy.

(3) The form and position error measuring instrument has high accuracy in measuring the straightness of the guide rail, and the manufacturing accuracy of the parallelism between the two axes of the side guide rail is also high, thus improving the measurement accuracy of relevant form and position projects.

(4) The shape and position error measuring instrument is equipped with a portable data acquisition device that can semi-automatic collect measurement data of various shape and position items, and transmit it in real time to the computer for calculation and processing. The faster the calculation speed of the evaluation software, the more accurate the calculation results. The calculation software can also separate the parallelism error of the guide rail to the two axes.

(5) The measurement length of the form and position error measuring instrument is 500mm (Type I), 800mm (Type II), and 1000mm (Type III)

2、 Technical parameters of the form and position error measuring instrument:

(1) Radial rotation accuracy: 0.4mm

(2) Straightness of side rails: 5um (Type I), 6um (Type II), 8um (Type III), 2 um/100mm

(3) Parallelism of side rails to two axes: 7um (Type I), 8um (Type II), 9um (Type III), 3.5um/100mm

(4) Tested Part-Diameter: 250mm

(5) Tested Parts_Length: 500mm (Type I), 800mm (Type II), 1000mm (Type III)

3、 Positional errorMeasuring instrumentEquipment for use:

(1) DGB-5B Inductive Micrometer and DGC-8ZG/C Axial Probe or Twisted Spring Meter

(2) The software for the eight measurement items covered by this instrument in the XW-250 positional error data acquisition and processing system (users can choose from 1-8 as needed), 486 and above desktop microcomputers (microcomputers do not need to be dedicated)

(3) Multi functional portable data collector (optional when collecting semi-automatic data, not selected if collecting and typing measurement data)
