CONSTRUCTION
Machine construction is of rugged design with turret made of highly ductile SG Iron casting. Feed frame is
made of very rigid gun metal with sufficient height to avoid spillover of powder. Turret rotates on needle
roller thrust bearing, which is immersed in oil for frictionless rotation. Specially designed 3 piece turret with
die plate of SS 316 can be provided to meet cGMP requirements and to increase the strength of die table
betweentwoconsecutivediepockets.
DRIVEARRANGEMENT
The main drive consists of a variable frequency AC Drive coupled with an AC motor within combination with
a precision worm reduction gear transmission The main motor and drive have been rated to permit the.
start of the machine at any speed under maximum load without any complications. Electrical and
mechanicalsafetydevicesareinstalled.
UPPER PUNCH PENETRATION
Ø This allows selection of the position within the die where the tablet is compressed & is measured from
thedietopfacetotheloweredgeoftheupperpunchtip.

Ø It is usual for the setting to be predetermined before commencement of marking tablets, although the
settingcanbealteredlater.
