Electrodeburring on SCM-440 Martensite
September 25, 2008
We're developing a fully CNC cog, and the material is SCM-440 with
Martensite treatment.
Due to its complex geometry, CNC burrs are thick, tough and cannot be
eliminated via tumbling or sandblasting. Especially, the tolerance is
30 microns max.
We are now considering electrodeburring or TEM.
I wanna know if it's possible to carry out electrodeburring process
on SCM-440 to remove burrs without changing dimension
significantly?
Please let me know if more information is required.
Many thanks!!
