  • What Is The Machining Accuracy And Machining Error Of Machine Tool Casting Parts?
    May 04, 2018

    The data of machining precision and machining error of machine tool Casting Parts describes the degree of conformity of the actual geometric parameters (size, shape and position) of machine tool Casting Parts with ideal geometric parameters. The higher the degree of conformity, the higher the accuracy of machined parts machined Casting Parts.

    Machine Tool Casting Parts Error: The deviation of the actual geometric parameters of the machine tool Casting Parts from the ideal geometric parameters is called the machining error. The size of the machining error indicates the level of machining accuracy, and the machining error is a measure of machining accuracy.

    "Machining accuracy" and "processing error" are two different concepts for assessing the accuracy of a part's geometric parameters. In production practice, the method of controlling the machining error or the modern active adaptation processing method is used to ensure the machining accuracy.

    The Casting Parts of the cast iron platform should be cleaned while digging one side, and the artificial sand and shot blasting are used as the sand removal. The cost of artificial sand removal is low, and some local treatments are not very clean. The shot blasting is the opposite and the cost is high. The surface of the cast iron platform/cast iron plate is very clean.

    The ideal temperature for shot blasting on cast iron platforms/cast iron plates is preferably close to the ambient temperature, but the cooling time varies from foundry to caster, so the temperature difference between cast iron platform Casting Parts and the blasting chamber is also very different. Shot blasting machine for general foundry can handle

    Casting Parts with a surface temperature of about 100°C. At such temperatures, rubber track conveyor shot blasting machines are not suitable, but steel crawler or manganese steel caterpillar shot blasting machines are selected. At high temperatures, such as up to 175°C, special high-temperature seals, curtains and hoist tracks must be added.
