Bed : |
The
bed casting is made close- grained cast iron ,well ground
and finished ,capable to withstand vibration free operation
under heavy load, accurately machined and ground on slide
way grinding machine for perfect bearing surface. The bed
is strongly braced with cross ribs provide full confidence
in the steady working of the machine under heavy turning
,surfacing, screw cutting etc. and thus initial accuracy
is maintained throughout its life. |

Head Stock |
|
| Casting
: |
Casing
of head stock is graded and seasoned to avoid unevenness
and effect of weather. |
| Boring
: |
Boring
of headstock is done with high technology method machine
to get good result of head stock parallelism of spindle
axis to bed surface and other results. |
| Bearing
: |
(A)
Brass : bearing is prepared from high grade lead bronze
metal which gives good lubrications and vibration less performance.
(B) Bearing : In
bearing type machine we use original SKF/TATA bearings ,
which gives accurate operations. |
| Gears
: |
We
use helical gears in head stock to get noiseless operation
and more strength in HD models. |
| Spindle
: |
We
use spindle manufactured fromEN-8 steel and ground for better
surface finish and accuracy . |
| (3)
Saddle : |
The
saddle is mounted on inverted V and flat ways of bed to
get long bearing carriage on the bad. This carriage the
cross slide and compound rest with square tool post. Screw
used in compound & cross slide are made of EN-8 with
gunmetal nut. |
| (4)
Appron : |
It
is double walled with independent drive motion for feeds
and screw cutting. It is well arranged to avoid sliding
surfacing of screw cutting feeds at the same time. It is
provided with a thread chasing dial and can be used while
cutting. |
| (5)
Gears : |
All
gears are checked by run out test and pitch match method
and checked in all respect. |
| (6)
Testing : |
Each
& every machine is passed through a hard test for 48
hours. |
