Description and Specification for Lab Tenders
Hand operated Precision Notching machine cuts all shearable materials
especially useful where box, chasis and panel blanks are to be made.
Notches as large as 160 mm x 150 mm in 16 Swg. mild steel can be made at
the corner or in any position along the edge of a sheet. Ease of
operation makes possible production rates which offen rival those of
power driven equipment. Powerfull action of notcher is obtained through
use of a roller cam, minimum operator effort is needed. Notches larger
and smaller than 90° can be made in two operations. Straight shearing
job can be done, too. Two handles of different lengths are provided.
Short handle for production speed on lighter materials; long handle for
notching heavier materials.
Blades : The machine is equipped with four blades to solve any
notching problem. The upper blades are fixed while the lower one's can
be adjusted. For smooth cutting 5% to 10'% shearing gap should be
provided. The blades are made out of special alloy
steel. The bottom blades have 4 cutting edges which gives longer
Adjustment of Blades : The adjustment of blades (Lower) is carried
out by the four hexagon screws, provided under the rectangular table.
Feeler gauge should be used for accurate gap setting. The machine has
been set for average size of material.
Table : A perfectly flat mild steel table has been fixed for resting
Gauges : Suitable gauges fixed on the top of table, have been
provided. The position can be changed according to requirement. For
fixing them at appropriate place tapped holes have been provided.
Operation : The sheet to be notched should be placed on the Tables.It
must bs butted against the gauge blocks. Then the head is brought down
manually and the shearing action takes place.
Maintenance : For the easy movement of the notching head. it is
necessary to lubricate the guideways and cam guides periodically.
STANDARD EQUIPMENT : Short handle for working with light materials.
Long handle for notching heavier materials, Adjustable gauges and
standard set of blades (fitted
