This is a lantern ring parts from SUS304 with surface roughness Ra3.2, angle 45 ° emphasis (outer diameter, inner diameter).
Since it is a part of the parts used for the automatic ignition device of the active furnace, burr or scratch is inadvisable. We processed it using NC lathe.
The outer diameter Φ38 (-0.009 ~ -0.025) has a tolerance because it is included in other parts.
With a general-purpose milling cutter, there are four Φ4 drills, which are machined with a high-precision drill.
Since the holes for milling cannot be chamfered, we did finishing once again with an NC lathe for the burrs that appear at that time.
