Range of Machining Limits

  • Meviy Welded Sheet Metal Service determines the machinability of welded areas and component parts within products.
  • Refer to the table below for machinability limits or dimensional ranges of welded areas within products.
  • For machining limits of component parts, refer to the sheet metal part design guideline “Range of Machining Limits“.
  • However, since the machining limits for components in the Welded Sheet Metal Service differ from those for some sheet metal parts, they are listed in the table below.
  • *Values may differ from those listed depending on surface treatment, shape, and processing conditions.
  • *When two or more plate thicknesses are present, the threshold for the thickest plate thickness is applied to the entire product to determine machinability.
