TONS REQUIRED PER HOLE TO PUNCH MILD STEEL HAVING 65,000 PSI TENSILE STRENGTH
E. PUNCH FULL AND COMPLETE HOLES. DO NOT PUNCH PARTIAL HOLES. The side
thrust encountered in punching a partial hole can force the punch over against the die and
result in punch or die breakage. This may result in serious bodily injury!
F. MAINTAIN SUFFICIENT MATERIAL BETWEEN THE PUNCHED HOLE AND THE EDGE
OF THE WORKPIECE. The edge of the punch should be clear of the edge of the workpiece by a
distance equal to the thickness of the material. Any edge distance less than this will result in a
deformed workpiece.
G. STAY WITHIN RATED PUNCHING CAPACITIES. Your 9012-24M Ironworker is designed to
operate in mild steel. Within conservative limits, it can also operate in medium, carbon annealed
steel and some forms of abrasion resistant steels. Conditions of high shock can be encountered
punching alloyed steels and accordingly, the machine rating must be reduced.
1 INCH (25MM) MILD STEEL IS THE MAXIMUM THICKNESS THAT CAN BE PUNCHED.
Punch to die clearance depends on material thickness. In mild steels, material thicknesses of 1/4
inch through 5/8 inch (6 to 16mm) should have a total punch to die clearance of 1/32 inch. (Punch
di1/32" = Die diameter). 3/4 inch thick and heavier (19mm) mild steel should have a
minimum of 1/16 inch clearance. (Punch di 1/16" = Die diameter.) In thin materials, the
recommended punch to die clearance is 1/10 of the material thickness. We do not recommend less
than 1/64 inch total clearance due to working clearances necessary in the punch ram and the
punch bushing.
FOR CAPACITIES, REFER TO THE PUNCH TONNAGE CHART BELOW.
