Safety First

Here are some safety instructions for the CNC Press Break. Remember... SAFETY FIRST!!!

Always make sure your hands are out of the way of the fingers and all moving parts
Be aware of your surroundings to ensure that you do not bump others with the counterweight.
If bending a small piece of metal, place it in the center of the brake.
Do not attempt to bend material thicker than 16 gauge.
Only use sheet metal with the brake. Don't try to bend round material!
You may not use the sheet metal machines without safety glasses!! (Should be obvious if you are following the rules of the shop)

Description

A Press brake is a metalworking machine that allows the bending of sheet metal. The brake is a Titan T25 CNC Press Break. The max material thickness capacity of this machine is 16 gauge mild steel. Because it is a CNC machine. It is able to do a wide variety of bend angles.

Here is an example of this piece of equipment being used.

Training

Operation

To opperate the CNC Press Break Under the 'Create Bend' tab, select 'new bend'. Then select the proper Punch (Standard 35 *) and Die (4-way w/risers). Then select the material that you will be bending and the proper angle that you want. Then add material thickness and bend width

Under the 'run' Tab select new and create a name for the job. Select the add bend button on the bottom right of the screen, make sure all settings are correct. Press the green run button on the bottom left

Press BOTH green buttons on the machine to move the punch down to the safety clearance area. Enter your material into the machine press the foot pedal twice to bend the material. (do multiple times if multiple bends on the same job)

Over/Under bending

If you set the machine to a 90 degree bend and it executes a 92 degree bend, this is called an overbend. The machine is able to account for this. If you happen to have an over/under bend select the OPPOSITE bend and input the amount of the over/under bend.

If a 90 degree input produces a 92degree bend select 'under bend 2 degrees'

If a 90 degree input produces a 88degree bend select 'over bend 2 degrees'

Demonstration

To demonstrate competency on the Bending brake you will be required to bend a piece of sheet metal to a 90 degree angle.

General Procedure

After the bend is properly set up in the computer, press the two green buttons simultaneously. This should lower the punch to the safety clearance zone.

Once in this zone insert your material into the machine where you want the bend to be and hold with two hands.

Press the foot pedal twice and be careful not to let the metal hit you while its bending.
