Repair and maintenance of cast iron inspection platform

The cast iron inspection platform is a ruler with accurate flatness, mainly used to inspect the flatness of flat plates, long guide rails, etc. by coloring method and indicator table method. It is also commonly used to inspect the straightness of workpiece edges by optical gap method. It is generally made of cast iron, and rectangular rulers are also made of bearing steel or granite.

Repair and maintenance

The cast iron inspection platform is easy to store and can be hung flat, without affecting its straightness and parallelism due to long-term flat placement.

The cast iron inspection platform is not easy to rust when stored, and does not need to be oiled during use. If not used for a long time, a thin layer of general industrial oil should be coated when stored to prevent rusting and affect accuracy.

Industry Trends

In order to reduce the production cost of the cast iron inspection platform and make the price of the bridge competitive in the market, 89.8% of the cast iron inspection platform production enterprises adopt the manual scraping process. Although manual scraping and grinding are relatively backward, for cast iron inspection platforms, it is an irreplaceable machining process that cannot be replaced by any mechanical processing when high precision is required. In order to improve the service life and working accuracy of the cast iron inspection platform, it is recommended to control the scraping and grinding to be above 0.02mm, which can prolong the service life and inspection cycle of the cast iron inspection platform. According to relevant information on scraping and grinding, as well as data obtained from scraping and grinding measurements, the processing requirements of this process can be met. The appearance of the cast iron inspection platform shows vibration marks, increasing the roughness of the product surface, affecting accuracy and aesthetics. After the scraping and grinding process, the above problems rarely occur. Prevent small local distortions on the working surface of the cast iron inspection platform to improve the accuracy of its use. Check the micro quality of the working surface of the cast iron inspection platform, namely the flatness of small peaks and valleys, and the micro surface, in order to ensure the service life of the cast iron inspection platform

Notes:

Tools must be inspected before work, and the use of unqualified tools such as corrosion, deformation, looseness, malfunction, damage, etc. is strictly prohibited.
