PENGARUH PROSES BURNISHING TERHADAP KEKASARAN DAN KEKERASAN MILD STEEL MENGGUNAKAN MESIN BUBUT KONVENSIONAL
Abstract: The Surface
quality is very
important in the
process of making
a product. It can
be indicated by
the level of
surface roughness and
hardness. This research aim
was to investigate
the effect of
burnishing process on
surface roughness and surface
hardness of mild
steel using a
conventional lathe. Burnishing parameters
used in this
research were the
spindle speed and
the depth of penetration. The spindle speed parameters used were: 130
rpm, 320 rpm, 570 rpm, and 770 rpm, while the depth of penetration parameters
were: 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm. This research also investigated the
effect of burnishing process
to the axis
alignment before and
after burnishing process. For the
purpose of this research, burnishing process used burnishing roll with
sphere diameter 19 mm and
R 5.5 mm.
The results of
the research showed that
burnishing proses could
improve the surface
quality. Optimal spindle speed
for surface roughness
is 570 rpm
for all depth
of penetration variables. The
increase of depth
of penetration would
decreas the surface roughness. The
increase of spindle
speed and depth
of penetration did
not increase the surface hardness and the axis alignment.
