Electrochemical deburring is the use of electrochemical machining to deburr precision work pieces and edges that are hard-to-reach, such as intersecting holes. The process uses a salt or glycol solution and electricity to dissolve the burr. The electric current is applied with a specialized tool to reach the burr location.
These are often used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process. To achieve optimal surface speed and cutting conditions, burrs are rapidly rotated at high speeds, often in the range of thousands or tens of thousands of RPM , which is typically the maximum speed supported by a given spindle.
Burr mill or burr grinder, a mill using burrs to crush the material, usually manufactured for a single purpose such as coffee beans, dried peppercorns, coarse salt, spices, or poppy seeds; Coffee grinder; Conical mill (or conical screen mill) Cutting mill, a device commonly used in laboratories for the preliminary size reduction of materials
After compression, the part shears for about 10% of the part thickness, and then fractures free of the strip or sheet. This fracturing produces a raised, jagged edge which is called a "burr". Burrs are typically removed by tumbling in a secondary process. Burr height can be used as an important indicator of tool wear.
A burr mill, or burr grinder, is a mill used to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. [ 1 ] [ 2 ] When the two surfaces are set far apart, the resulting ground material is coarser, and when the two surfaces are set closer together, the resulting ground material ...
Shearing, also known as die cutting, [1] 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. [2]

Chucking reamers, or machine reamers, are the most common type of reamer used in lathes, drill presses, and screw machines that provide a smooth finish to the hole. They come in a variety of flutes and cuts (e.g. right hand cut, left hand spiral, straight flute) as well as different shank types.
