Press Tools

1. Shaving:
It is an operation of removing a
small amount of material a around the
edges of a previously blanked
stampings or pierced hole to get a
good finish on the cut edges and
accurate dimensionswith min. radius
at the edge of the component.

2. Side cam tool :
Side cam transformsvertical motion
from the press ram into horizontal or
angular motion in the tool.

3. Lancing:
It is a combination of cutting and
bending operation along a line in the
work material.

9. Flaring, lugging or collar drawing:
The process of forming an outward flange
on parts is called flaring operation.

10. Progressive tool :
progressive tool are those in
which progressive tools perform work
at a number of stations simultaneously.
A final component is taken off at final
station, with each stroke of press.

11. Compound tool :
In compound tool all or
maximum features of the component
can be produced in one stroke of the
ram. Basically compound tools are
inverted tool. Used to maintain high
accuracy between the features and
to get burr on same side.

12. Combination tool :
In combination tool two or more
operations such as forming, drawing,
extruding, embossing may be
combined on the component with
var ious cutting operations like blanking,
piercing, broaching and cut off.

18. Sub press tool:
Sub press tools blank and form
very small parts. the die components are
retained in a sub press. Sub press is a
small press which is operated in large
one.
