Description

Product Introduction:

The surface roughness and profile measuring instrument is an all-in-one device that measures both contour shape and surface roughness, offering powerful capabilities for analyzing and quantifying these parameters. It enables precise measurement of dimensional, geometric, and surface‑roughness characteristics, and is used to assess the straightness, flatness, angularity, roundness, double‑groove profiles, and double‑arc profiles of various mechanical components.

Parameters of both micro‑geometric structure and macro‑geometric shape. The system employs an imported sector‑shaped grating for data acquisition, offering a wide measurement range and high accuracy. The entire system is easy to assemble and align, simple to operate, and highly efficient in measurement. It is suitable for industries such as machining, automotive, motorcycle manufacturing, precision hardware, precision tools, mold making, cutting tools, and optical components.

Product Features:

1. This high-performance, high‑configuration integrated instrument for surface shape and roughness measurement can simultaneously measure both parameters, making it convenient to use.

The requirement for one-time, single-point measurements significantly improves efficiency.

2. In the ×-axis direction, imported high-precision linear guides are used as a reliable reference for horizontal motion, and imported high…

Mobile measurement using precision grating technology.

3. The axial direction employs a ball-screw drive system powered by an electric motor, enabling automated operation that is both convenient and reliable.

4. The sensor employs a high-precision, intelligent encoder with a rotary optical grating scale, offering a wide measurement range, high accuracy, and excellent stability.

The measurement software is developed in-house for the Windows platform and is compatible with Windows XP, Windows 7, and Windows 8.

The numbers are processed according to the national standard parameters.

5. The measuring worktable can be adjusted in the Y‑direction, in a sector‑shaped plane, and at various angles; measurement sensors…

The instrument can measure the tilt angle based on the workpiece conditions, meeting users’ measurement requirements.

6. The standard sample block is made of an optical glass substrate, making it resistant to scratches. It has been calibrated by the National Institute of Metrology, with accuracy that can…

Damn, it has a long service life;

7. The measurement functions are powerful, with intuitive graphical display and printing, and a comprehensive mathematical model.
