    FAQ

    Q1: What is a 3.2 RA finish?
    A1: 3.2 RA finish refers to a surface roughness measurement where the roughness average (RA) is 3.2 micrometers (µm) or 125 microinches. RA is a common parameter used to quantify the smoothness or texture of a surface, indicating the average deviation of the surface profile from the mean line over a specified length.

    3.2 RA finish is often considered a moderately smooth finish and is typically used in various industries where a certain level of surface smoothness is required for functional or aesthetic reasons. This level of roughness can be achieved through different machining processes such as grinding, polishing, or other finishing techniques.

    Q2: What is the difference between surface finish and surface roughness?
    A2: Surface finish and surface roughness are related but distinct concepts. Surface roughness specifically refers to the fine irregularities on the material's surface, which are a result of the manufacturing process. These irregularities are usually quantified in micrometers (µm) or microinches (µin) using parameters such as Ra (roughness average) and Rz (average maximum height). Surface finish, on the other hand, is a broader term that includes surface roughness, waviness, texture, and flaws. Waviness refers to larger-scale surface deviations, texture indicates the directionality of surface patterns, and flaws include defects such as cracks and scratches. In summary, surface roughness is a part of surface finish, and surface finish provides a comprehensive assessment of surface quality.

    Q3: What is SA and SQ in surface roughness?
    A3: In surface roughness measurement, Sa and Sq are parameters used to quantify three-dimensional surface texture. Sa (Arithmetic Mean Height) represents the arithmetic mean of the absolute values of surface height deviations measured from the mean plane, analogous to the 2D parameter Ra .Sq (Root Mean Square Height), on the other hand, is the root mean square (RMS) value of surface height deviations from the mean plane, akin to the 2D parameters Rq or Rms.

    Sa provides a measure of the average height variation on the surface, while Sq emphasizes larger deviations due to squaring and averaging the deviations. These parameters are crucial for comprehensively assessing surface texture and roughness in three dimensions, widely applied in fields such as materials science, manufacturing, and quality control.

    Tips: How does an digital surface roughness meter work?

    When measuring the surface roughness of a workpiece, the sensor is placed on the surface to be measured. The internal drive mechanism of the instrument drives the sensor to move uniformly along the surface being measured. The sensor detects the surface roughness using its built-in sharp stylus. As the surface roughness of the measured workpiece causes displacement of the stylus, this displacement changes the inductance of the sensor's coil.

    The change in inductance generates an analog signal at the output of the phase-sensitive rectifier, which is proportional to the surface roughness of the measured surface. After amplification and level conversion, this signal enters the data acquisition system. A DSP chip processes the collected data through digital filtering and parameter calculation. The measurement results are displayed on an LCD screen and can be communicated with a PC for data analysis and printing.
