| (1) 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. |

|
| (2) 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. |
