  • Analysis And Preventive Measures For Ring Grinding Burns (2)
    In the surface process, such as grinding a surface on a vertical single-head grinder, the following factors may cause burns if the operating specifications are correctly followed. a. The grinding wheel shaft moves, increasing the instantaneous grinding amount and causing burns; at this time, the grinding wheel shaft bearing must be tightened or the bearing must be replaced. b. The disk on the workbench jumps or rotates unevenly, which increases the amount of instantaneous grinding and causes burns; various components of the disk reducer, such as worm gears, worms, etc., must be inspected and worn parts replaced.
  • Analysis And Preventive Measures For Ring Grinding Burns (1)
    During the grinding process of the bearing ring, due to the cutting, scoring and frictional effects of the abrasive grains on the workpiece, the metal surface is plastically deformed, and the relative displacement between the metal molecules inside the workpiece generates internal friction and heat; when the grinding wheel is cutting, relative to the workpiece The speed is very high, causing severe external friction with the workpiece surface to generate heat. And because the cutting of each abrasive is instantaneous, the heat is generated instantaneously and cannot be dissipated in time, so the instantaneous temperature in the grinding area is relatively high. High, generally reaching 800~1500℃. If the heat dissipation measures are not good, it is easy to cause burns on the surface of the workpiece, that is, secondary quenching and high-temperature tempering will occur on the surface of the workpiece (generally tens of microns to over microns), which will cause damage. The structure on the surface of the workpiece has been removed, and severe burns can be seen with the naked eye. A severe burnt yellow or black oxide film appears on the surface. Minor burns can only be observed after being etched with dilute acidic solution. The burned area will appear black. Burns can reduce the service life of the workpiece.
  • Machining And Safety Of Magnesium Alloy Parts
    Magnesium alloy with a density of 36% is lighter than aluminum alloy, 73% lighter than zinc alloy, and 77% lighter than steel. It is recognized as the structural metal material with the smallest mass. The machining of small batches of magnesium alloy parts can be carried out on small manually operated machine tools; when processing magnesium alloy parts in large batches and with high efficiency, it will be more economical to use dedicated large-scale automated machining centers or computer numerical control machine tools. Compared with those metal materials with poor machining properties, magnesium alloys with good cutting properties have very outstanding advantages. For magnesium alloys, powerful cutting can be performed at high cutting speeds and large feeds, so that the number of machining hours can be reduced. Therefore, when completing the same task, if magnesium alloy is used as raw material, the number of processing equipment can be reduced, infrastructure investment can be saved, the floor space can be reduced, and labor costs and management expenses can be reduced.
