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.
For example, endmills can be used in routers, and burrs can be used like endmills in milling by CNC or manual machine tools. [3] These are often used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process.
Because the material is so tightly held and controlled in this setup, part flatness remains very true, distortion is nearly eliminated, and edge burr is minimal. Clearances between the die and punch are generally around 1% of the cut material thickness, which typically varies between 0.5–13 mm (0.020–0.512 in). [ 8 ]
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 ...
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
Abrasive flow machining (AFM), also known as abrasive flow deburring [1] or extrude honing, [2] is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a workpiece. [1] [3] [2] This fluid is typically very viscous, having the consistency of putty, [2] [3] or dough. [1]
Finally, vibrations can be generated by mechanical systems: [6] the frequency is given by the combination of the rotation speed and the number of oscillation per rotation (a few oscillations per rotation), with magnitude about 0.1 mm. This last technology is a fully industrial one (example: SineHoling® technology of MITIS).
The O-Rings allow the system to become perfect centric during the idle speed but allow a small movement of the rotor within the head. Failure of the burr to run centrally causes a number of clinical defects: The burr will judder; this will cause excessive, damaging vibrations leading to cracking and crazing in the material being cut. It is also ...
