Flat wave meter (for calibrating flat plates)

OneSY-PBDY-02Flat wave meter (for calibrating flat plates)Introduction:

The SY-PBDY-02 planar wave meter is a convenient tool for detecting local flatness. According to the national standards for "cast iron flat plate" and "rock flat plate", the detection requirements and methods for the plane wave momentum of the flat plate working face are specified. The detection principle of the plane wave meter is derived in detail, and the local flatness error and local defects of the flat plate are given. Different precision detection tables (micrometer, inductance micrometer) can be configured to meet the requirements of different detection accuracies. It is a high-precision testing tool used in flat panel metrology and standardization.

2、 Structural composition:

The planar wave meter consists of a fixed foot, a wave meter, a detection table, and a set screw. Three fixed legs can ensure the stability of the wave meter during movement and serve as a reference for flatness detection; The setting of the wave meter facilitates the installation and locking of detection gauges (micrometer, inductance micrometer, torsion spring comparator). In addition to measuring the fluctuation of the flat surface, it is also necessary to detect the deflection of the flat surface. The detection device is placed on the working surface of the tested flat surface. When no load is applied, the measuring head of the torsion spring comparator is in contact with the working surface (to ensure accurate measurement, a thin measuring block can be placed between the measuring head and the working surface) and the reading is recorded. Then, a force is applied according to the specified rated load and the reading is recorded; The difference between two readings is the deflection value of the tested flat working surface under rated load.

三． SY-PBDY-02Flat wave meter (for calibrating flat plates)Wave measurement method:

Place the plane wave instrument on the working surface of the cast iron flat plate, and move the plane wave instrument along any straight line direction. The movement distance should be half of the diagonal length of the flat plate and should not be less than200mm.Take the indicator table of the plane wave meter(The division value is0.001mm)The difference between the maximum value and the minimum value is the planar fluctuation of the inspected flat working surface.
