Comparison of Machined Surfaces in Continuous Facing (Steel) Surface finish quality/surface roughness equivalent to or above conventional grade
Machined surface (vc = 330 SFM or below)
Machined surface (vc = 330 SFM or below)
At machining start Ra = 1.6 Rz = 6.9
After wear development Ra = 2.5 Rz = 15.8
At machining start Ra = 1.9 Rz = 8.2
After wear development Ra = 2.5 Rz = 14.1
