Types of Plastic Burrs and Deburring Processes - Craftech ...

A burr (also known as a "flash") is an unwanted raised edge or small piece of material left after a part has been worked in a manufacturing process. It can be metal, rubber, plastic or really any other material used in manufacturing. Machining operations such as grinding, drilling, milling, turning, tapping, slotting etc. cause burrs in machining operations. As you can see in the picture ...

Modeling of material removal rate in electric discharge ...

The mechanism of material removal in electric discharge grinding (EDG) is very complex due to interdependence of mechanical and thermal energies responsible for material removal. Therefore, on the basis of conceived process physics for material removal, an attempt has been made to predict the material removal rate (MRR).

Effects of Grinding Passes and Direction on Material ...

Nov 15, 2018· A three-dimensional finite element model of rail grinding was established to explore the effects of grinding passes and grinding direction on the material removal behaviour of grinding rails during the grinding process. The results indicate that as the number of grinding .

Machining Molybdenum

ductility through stress relieving methods, or by grinding the material to remove surface contaminants. Note that if you weld the pure molybdenum in the open atmosphere, the material is at risk of absorbing the nitrogen and oxygen, thus causing oxidation and causing brittleness. Cleaning Cleaning molybdenum is an easy and straightforward process.

Honing and Lapping Compared - Metal Cutting Corporation

Sep 14, 2017· The process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through double disk grinding — because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.
