Sheet Metal Shear Blade Angle

This video demonstrates our metal shear blade sharpening service.

Sheet metal shear blade angle.

We manufacture and stock replacement blades for ironworkers. Makes cutting exposed fastener panels easy. Grinding can sharpen any shear blade up to 14 within the same precision tolerances as new knives to maintain high productivity and quality cuts. Ideal for shearing heavy gauge exposed fastener panels.

But the discs wear down quickly cut slowly and shrink in diameter as you use them. Its solid steel precision machined blades cut straight and contour lines quickly and quietly with up to 5 16 in. In the paper cutting world around 24 degrees on the top blade is pretty common would have no qualms feeding 30 thou brass and similar through these machines from reguards to blades chipping do to too shallow a angle though if i was grinding the blade i would probably add a small secoundry honed land around the 30 degree range but hoestly if you look at a typical metal shear the edges of the blades are often nearly at 90 degrees so i really would not sweat the details too much. We supply shear blades for the following machines.

Setting the blade on an angle decreases the amount of force required but increases the stroke. The tolerances for sharpening the width and thickness will be parallel to within 002 from end to end. This powerful yet compact makita fiber cement shear this powerful yet compact makita fiber cement shear kit is engineered for a range of applications including drop ins for sinks flooring and showers as well as exterior tasks like siding gable angles and window openings. Able to shear straight at 90 degrees and up to an 8 12 gable.

This angle is referred to as the shear angle. It shows how we sharpen two sheet metal guillotine shear blades at 3 meters each on our wor. Also the upper blade is usually angled so that the cut progresses from one end to the other thus reducing the required force. Whether you are in structural steel fabricating ornamental iron rail or metal buildings we can provide replacement blades for your ironworker.

Eliminates burred edges and flying metal on your metal roof panel or sheet metal. An angle grinder fitted with an abrasive metal cutting disc works well to cut all kinds of metal including bolts angle iron rebar and even sheet metal. The heavy duty pivot shear comes with one custom blade set. A 5 degree shear angle decreases the force by about 20.

Instead we recommend using a diamond blade that s rated to cut ferrous metal. For larger shears the moving blade may be set on an angle or rocked in order to shear the material progressively from one side to the other. Flat bar shear blades. In most devices the lower blade remains stationary while the upper blade is forced downward.

We strive to meet all of our customer s needs with high quality products and fast turnaround times. The upper blade is slightly offset from the lower blade approximately 5 10 of the sheet thickness.
