Zhongtu Instrument SJ5800Integrated Profilometer adopts ultra-high precision nano-diffraction optical measurement system, ultra-high straightness grinding-level friction guide rail, high-performance DC servo drive system, and high-performance computer control system technology. It can perform one-time scanning measurement of the contour, waviness, and roughness of part surfaces, especially for one-time detection of roughness and contour dimensions on large-range curved surfaces and inclined surfaces, such as arc surfaces, spherical surfaces, and special-shaped surfaces, for various roughness parameters (such as Ra, Rz, etc.), micro contour Pt, and waviness parameters.

Product Introduction

SJ5800Integrated Profilometer ensures ultra-high stability and straightness of measurement through ultra-high straightness grinding-level friction guide rails and high-performance servo drive motors. It uses an ultra-high precision nano-diffraction optical rotary axis measurement system and a high-precision linear grating X-axis to establish a two-dimensional coordinate system of the workpiece surface contour. The computer employs a high-precision calibration system to correct and calibrate the sampled data, ultimately restoring the workpiece contour information and displaying it as a graph. Using the analysis tools provided by the software, various roughness parameters and contour parameters can be analyzed for both the contour and micro contour.

Application Fields

SJ5800Integrated Profilometer can be widely used in precision machining, automotive, bearings, machine tools, molds, precision hardware, and other industries. This instrument can inspect part surfaces, especially large-range curved surfaces such as arc surfaces, spherical surfaces, and special-shaped surfaces. It is a powerful tool for fine roughness measurement in the field of large curved surface measurement (bearings, artificial joints, precision molds, gears, blades, bearing rollers).

Application Cases

For example, high-precision contour parameter detection of key engine components such as the thermostat inner cylinder, valve rocker arm, and camshaft.

1) Roughness detection of the thermostat inner cylinder contour

2) Roughness detection of the valve rocker arm inner hole

3) Contour dimension and roughness detection of the engine camshaft
