The metal stamping quote will include the cost for the tooling tool die set to produce the parts and also the part cost.
Burr direction in sheet metal.
To the edges where burrs may occur to reduce the occurrence of burrs.
The sheet metal stamping process is a very fast and precise manufacturing process.
Burr height up to 10 of material thickness can be expected.
For elevator stainless steel sheet metal parts the product design department considers the burr formation mechanism and removal method at the product and process design stage to minimize burrs.
If operators and technicians try to solve cut quality problems without considering the process fundamentals they may be shooting in the dark.
Using burr free design such as.
They include burrs fracture burnishing rollover and work hardening.
Figure 2 a burr or protruding ragged edge shown at 100x magnification occurs as the material is sheared at an angle against the blanking direction.
The burr is a thin ridge of material that is formed due to the elongation of metal during the final separation of the sheet.
It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.
