Dimensional Reworking

Vibratory De-Burring
Powdered metal parts are rolled in rotating barrels or agitated in vibrating tubs (usually with some form of abrasive media and water) for:

  • Cleaning
  • De-burring
  • Polishing
  • Rolling
  • Burnishing

Sizing And Re-Striking

Dimensional tolerance specified by the part designer may require additional sizing and re-striking:

  • When part design is too demanding for pressed and sintered part
  • To reduce dimensional variability
  • To increase density in selected region of a powdered metal part

CNC Machine


Machining parameters for powdered metal parts are different from those used for castings or wrought components. The powdered metal material contains pores that can interrupt cutting tool performance. As the amount of porosity decreases, powdered metal parts machine more like cast or wrought parts with a similar microstructure.

ASM Basic Machining Capabilities:

  • Turning
  • Milling
  • Drilling And Tapping
  • Grinding
