The service life of the North Heavy grinding table is very long. As long as it is used and maintained correctly, the accuracy of the grinding table's working surface can be maintained for more than two years.
The grinding table is used in industry to inspect the flatness of workpieces, serving as a reference plane for precision measurement. It is used as a benchmark for machine tool inspection and measurement, checking the dimensional accuracy or geometric deviation of parts, and performing accurate and precise marking. The grinding table is made of HT250 or ductile iron material, with the highest requirements for accuracy and surface finish among cast iron platforms. It is an indispensable basic tool in mechanical manufacturing.
Methods and steps for verifying the flatness of the North Heavy grinding table: Based on the shape and size of the measured platform, select the layout of measurement points and determine the number of segments in each section and the span of the bridge plate. Place the bridge plate with a built-in level or reflector on the measured section, move it along the measurement direction with equal spans, connecting end to end, and record the readings at each position. When using a level, adjust the measured surface to be roughly horizontal. When using a collimator, adjust the measured line to be roughly parallel to the instrument's optical axis. Process the data based on the segmented verification results to determine the flatness value.
Generally, the service life of a grinding table is very long. As long as it is used and maintained correctly, the accuracy of the grinding platform's working surface can be maintained for more than two years. Grinding table accuracy: When accuracy decreases, it can be restored through adjustment or scraping processes. The grinding platform itself can last 50 to 100 years.
Grinding table accuracy: Divided into four grades: 0, 1, 2, and 3.
