Hamenaco screw harmonic CSF-65-160-2UH produces radial elastic deformation of flexible wheels with external teeth and a wave generator mounted inside the flexible wheels in an oval shape with flexible rolling bearings on the outer ring. When only surface roughness is measured, surface roughness information can be obtained from the measurement signal by filtering (hardware or software filtering).
In the needle tracing with relative reference, the Hamenaco screw harmonic CSF-65-160-2UH probe moves laterally on the surface under test along with a sliding block supported on the surface under test. Slide block also known as guide, skid, it relies on the movement of the measured surface to form a relative reference line, but also acts as a mechanical filter. The shape of the slider is mainly circular and flat. Generally, the radius of the arc slider is not less than 50 times the cutoff wavelength, and the Harmonics OF the Hamanaco screw CSF-65-160-2UH are applicable to most of the surfaces tested. For the measured surface with large texture spacing, the plane slider should be selected, and the supporting length should be greater than 2 times the texture spacing.
2) Contact stylus form and measuring force In contact stylus tracing, the stylus form and the choice of measuring force affect the measurement result *. If the tip radius of the stylus is too large, the vertical resolution decreases. If the radius of hamenaco screw harmonic CSF-65-160-2UH is too small, it is easy to scratch the workpiece and the stylus itself is also easy to damage. In addition, the smaller the tip radius, in order to reduce the pressure per unit area, the allowable measuring force should be smaller. When the measuring force is small, the allowable measuring speed is small, otherwise the tip will be separated from the measured surface during the measurement.
3. Measurement of screw screw error
C1) Static measurement the measurement method and instruments used have the same error as the measuring pitch, but the number of measurement points should be larger to describe the actual helix as carefully as possible.
