High Precision Roughness and Contour Measuring Machine

Zhongtu Instrument SJ5800 High-Precision Roughness and Contour Measuring System can inspect part surfaces, especially large curved surfaces such as arcs, spheres, and irregular shapes. It is widely used in precision machining, automotive, bearings, machine tools, molds, precision hardware, and other industries. With a resolution of up to 0.1nm and a system residual error of less than 3nm, it is an essential tool for fine roughness measurement in large curved surface applications (bearings, artificial joints, precision molds, gears, blades, bearing rollers).

Measurement Functions

1. Create Coordinate System: Point-line, two-point X, two-line, and other workpiece coordinate systems.

2. Measurement Tools: Extract the highest point with a rectangular selection, extract the center point with a rectangular selection, automatically extract multiple points to form a line with a rectangular selection, automatically capture multiple points to form a line, automatically extract the pitch diameter line of threads with a rectangular selection, extract arcs/circles with a fan-shaped selection, etc.

3. Construct Features: Intersection points, center points, angle bisectors, tangents, inscribed circles between two lines, resampling, perpendicular lines, parallel lines, feature offset, inscribed circles between two arcs, line rotation, etc.

4. SJ5800 High-Precision Roughness and Contour Measuring System can measure geometric quantities: points, lines, circles (center coordinates, radius, diameter), arcs, centers, angles, perpendiculars, distance from line to line, distance from line to circle, angle between X/Z coordinates, coordinate difference, total process distance between two points, area, etc.

5. Geometric Tolerances: Evaluation of straightness, roundness, parallelism, perpendicularity, coaxiality, position, profile, and other geometric tolerances.

6. Quick Tools: Coordinate labeling, intersection of two lines, angle between two lines, intersection labeling with thread selection, step height, ball screws, Pt selection with frame, groove width, intersection point of offset point and contour line, intersection point of offset line and contour, base edge/base point standards, and other special tools for rapid measurement.

7. Equipped with an automatic inflection point detection function, it can automatically detect inflection points along the X-axis according to program settings.

8. Surface Roughness Evaluation: R parameters, P parameters, W parameters, core roughness Rcore, Motif, and other micro-roughness parameters.

9. Supports tolerance setting and qualification judgment.

10. Supports contour comparison in three formats: point CNC, .xml, and .dxf. If the standard contour contains labels, corresponding labeling results can be automatically calculated.

11. Supports modification of contour scan data, including deleting outliers for analysis.

12. Supports stitching analysis of multiple records based on a unified reference.

13. Supports custom color management for contour features, labeling features, and geometric tolerances.
