What is a shear operation?
Shearing, also known as die cutting, is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.
What does a shear operator do?
This position is responsible to set up and operate power-shear machines to cut steel and other materials, such as sheets and plates to specified dimensions and angles. Main Responsibilities: Shears and trims metal sheet and plate according to written or verbal instructions, sketches, blue prints etc.
What are shearing tools?
Shearing machines are multipurpose devices used in the cutting of alloys and other sheet metal. Some shearing machines use a scissor-like, angular shear action to cut metal into sheets or strips. Other, larger machines use a straight shear action with the blade fixed at an angle as opposed to the angular movement.

How do you adjust shear blades?
Shear Blade Adjustment Video
- Loosen slightly the 5/8” bolts.
- Take the two jacking bolts per side as seen above and snug them just to the point you can’t.
- Repeat this step on the other side of the blade.
- Once you feel that you have proper tension, take a large adjustable wrench and place it on.
