Mechanical Shear

When buying a mechanical shearing machine, there are several factors to consider:

1. Type of metal being sheared: The thickness, type, and consistency of the material you plan to shear will determine the type of shearing machine you need.
2. Sheared metal output: If you require a high volume of sheared material, specific improvements should be made.
3. Shearing system: Shearing systems can be pneumatic, electric, hydraulic, or mechanical³. Mechanical shears have the moving blade driven by a rotary motor through a screw, toggle, lever, or other mechanism.
4. Design of the shearing machine: Consider the design and features of the machine. Some 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.
5. Fixed or adjustable rake angle: The angular configuration of the blades is called the rake. Both rake and clearance are a function of the type and thickness of the material to be cut.
6. Operation size: Consider the size of your operation and the capacity/operating force required to cut a part during production.
7. Stroke speed: This is the linear speed of the slide or ram during pressing or ram advancement steps.

Remember to also consider factors such as maintenance requirements, cost, and warranty when making your decision. For example, mechanical shears are known for being fast, low maintenance, and offering an array of features with low power consumption. They can cut metal sheets ranging from 14 gauge to 10 gauge mild steel.
