What issues should be noted when using a cast iron inspection platform?

The flatness of the working surface of the cast iron inspection platform refers to the distance between two parallel planes that accommodates the actual working surface of the flat plate. Its value can be obtained by "base transformation" based on the calibration results of the diagonal method and the loop method. The flatness of the flat working surface is the main accuracy indicator for measuring the quality of the flat plate. The accuracy level of the flat plate is determined based on the allowable tolerance value of the flatness of the flat plate working surface, so it is important to pay attention to the verification of the flatness of the flat plate working surface. The accuracy of flatness calibration for flat plates is the quality of their use. The layout of line points, coincidence, uncertainty of calibration tools, calibration methods, evaluation principles, and data processing are the key factors for the accuracy of flatness calibration of flat plates. Pay attention to these issues during the flatness calibration of flat working surfaces, which can help improve the quality of calibration.

There are marked lines on the surface of the cast iron inspection platform, which are used by the plumber to inspect the workpiece and mark the reference lines when marking the workpiece. The specific dimensions of the marked lines are made by the user according to their usage situation.

Cast iron inspection platform: It is a reference plane used for measurement in production workshops or metrology departments; Compared with the marking plate, the marking plate is a reference plane used for marking in production. Although both types of flat plates are reference planes, their processing methods, plane accuracy, and functional functions are different. The working surface of the inspection plate using the coloring method needs to be scraped and ground; The working surface of the inspection board for other purposes needs to be scraped, ground or ground; Just use a sword light to mark the working surface of the flat panel. From this, it can be seen that the plane of the inspection plate is the same as the marked plate.

Precautions for use

The cast iron inspection platform should be placed in a location that is convenient for work and has a suitable line of sight; Platform drills and grinding machines should generally be installed at the edge of the site for normal operation.

When using a cast iron inspection platform, the workpiece should be handled gently on the platform. Do not forcefully hit the platform to avoid damage to the cast iron inspection platform.

The bench drill, electric drill, and grinding wheel used should be checked regularly, and any damage should be reported to the internship teacher in a timely manner. They should not be used until they have been repaired.

When using electric tools, it is necessary to wear insulation protective equipment. Wear glasses to protect your eyes when using grinding wheels. Install protective nets when signing and cutting on the pipe platform. Use a brush to clean iron filings, do not blow directly with your hands or mouth.

The blank and processed parts should be placed in the designated position, arranged neatly and steadily, easy to take and place, and avoid possible damage to the workpiece and surface.
