TOOLING ADJUSTMENT
1.
The amount of joint squeeze is controlled by adjusting the upper tooling (punch) either towards the die or away
from the die with the tooling adjusting screw.
2.
For thin material the punch will have to be lowered (moved towards the die) and for thick material it will have
to be raised (moved away from the die).
3.
The correct tooling adjustment is the most critical adjustment on the Surelok II. Please read the tooling
adjustment instructions in a later section of this manual.
MATERIALS TO BE JOINED
1.
The Surelok II is capable of joining commercial quality mild steel up to two ply 10 gauge mild steel.
2.
For best results both ply of material should be of the same or similar thickness.
3.
If different thicknesses are to be joined the best results will normally be found with the thicker material on the
upper (punch) side of the two ply although this is not always possible.
4.
The thicker material should not be more than twice the thickness of the thinner material and the combined
thickness of the two-ply should not exceed
0.276”.
5.
Other materials can be joined with the Surelok II as long as they are not harder than commercial quality mild
steel. In most cases both ply should be of the same hardness, but if a different hardness is used for each ply
(not recommended) the harder material should be on the upper (punch side) if possible.
DIE SELECTION
1.
There are three sizes of dies required to cover the complete range of material that the Surelok II can handle.
2.
The punch in the upper tooling is not changed for different material thicknesses.
3.
The die selection chart can be used to find which die will be most suitable for your application, however the
chart is a guide only, different types of material may require a different size of die.
OTHER OPTIONS MAY BE AVAILABLE, PLEASE CONSULT FACTORY FOR DETAILS.
