There is a chart on the machine that tells you what the tonnage requirements are for a particular piece of metal. For instance, if you use the rule of 8 X the material thickness for the die opening, you can work ¼" steel plate at 15.4 tons per foot. If you want to brake a 1/8" sheet, it would require ½ of the 15.4 tons or 7.7 tons.

Actually, the rated tonnage is the maximum capacity. Once you figure out what required tonnage per foot is, you simply take the number of feet you would like to do and multiply it by the tonnage. When working short pieces, it is always recommended that you move the part around a little bit to avoid making an impression on the bed.

Everything you will ever bend on a press brake will have resistance. This resistance will cause the bed and the ram to deflect. Camber is a small amount of crown put in the bed or ram to allow for the deflection.

Yes, the machine should be leveled and bolted to the floor. You can loose 25% of the machine's energy through loss of torque.

Typically, you can cut from 25 GA (.020") to full capacity.

No, your shear will cut to capacity in mild steel, typically 65,000 PSI. It will cut to about 75% of its capacity in stainless steel and can cut to well over its capacity in aluminum or brass.

No, you can cut to full capacity at about 2 degrees and you can increase the rake angle to cut thicker pieces.

Rolling is when you start the bending-operation 4" or 5" from the edge of the plate, or possibly longer, depending of the geometry of the machine.

GO BACK TO TOP

When a part is rolled out to the edge (typically 1.5 to 2 times the material thickness), you are pre-bending it. This requires more energy from the machine, so your pre-bending- capacity is about 80% of the rolling capacity.

On a SIP-roll it is only possible to pre-bend one edge. Therefore, the material must be removed and rotated 180 degrees and re-inserted into the machine to pre-bend the trailing edge.

This machine allows you to pre-bend both edges without removing the plate from the machine.

This machine also allows you to pre-bend both edges in the machine without removing the plate. It is the best choice for cone-bending. Because it is a pinch type machine, it is well suited for CNC work.

Every piece of metal that is rolled has a resistance to the rolling. This resistance puts pressure on the top roll causing it to deflect. Camber or crown is machined into the roll to make it roll true. Typically, a job shop-camber will be at 50% the value of the full capacity of the roll. This will give a user the whole middle range to work without the need for shimming. For manufacturing, a special camber will be worked out with the buyer that will suit his operation.

Yes, however it is not like a press brake. You can't work a piece that is half as long to twice the capacity. You will be given a capacity chart when you buy the machine that will give you the capacity at various lengths and diameters. You can also give us a call and we can give you the specific capacities.
