General Comments
3.7 Boschert technical alert
Boschert‘s line of 90 degree fixed and 30-120 degree vari-angle notching machines are rated
at:
- Mild steel= 50,000 psi
-Stainless steel= 65,000psi
Some customers are not able to notch to capacity using A-36, 1/4“ structural sheets. A-36
has a tensile strength anywhere from 55,000 to 85,000 psi. TH2.3 Location of the operating
instructions. This material is 10% to 60% over the rated capacity of mild steel on the
machines.
If the inital cut of the A-36 is not continuous and steady, the tensile strength probably is harder
than the machines rated capacity. (Example, first stroke stops and a second stroke is
needed after restarting the machine.) Continued use in this situation can result in main piston
fatigue and finally failure.
Note: Not all A-36 is created eqaul. Some will work fine and some will be over capacity. WE
suggest you talk with your supplier about the sheets you are using.
