Custom CNC Precision Machining Aluminum Parts

[]

  Our company has 10 years of experience in custom metal fabrication, and is a large manufacturer of Machining metal and plastic parts. In high volume machining, based on the workpiece aluminum alloy is soft with a high degree of ductility, aluminum parts often due to the effect of internal stress, the cutting heat and clamping and produce varying degrees of deformation, in order to ensure the forming quality and control deformation of the aluminum parts, in the CNC precision Machining Aluminum parts of the process required to take the treatment are:

  (1) aluminum parts in the milling process, whether rough or fine milling, should be symmetrical processing and multiple turn milling, so that the stress release on both sides of uniform.

  (2) when the two sides of aluminum parts are finished rough machining, place them for several hours (usually 48H) natural aging, so that the remaining stress is fully released, and then processed.

  (3) When single-sided Milling Aluminum parts , as far as prossible to take a small margin and more path.

  (4) As the aluminum alloy material with high strength, high toughness characteristics, should control the cutting depth, cutting to ensure adequate cooling, to prevent the deformation of parts caused by cutting heat, but also pay attention to the hardness of fixtures.
