How to identify and saw the matrix do good piece burr cut big reason

Saw the matrix to identify how to do: Use a permanent marker to make the hole in the middle of the blade near the logo, after the device has a flange on the blocked will not be erased; using laser GUSHI core bits for concrete  marking, such as fast peerless blade; most good is pneumatic marking. Hot rolled plate (plate oil must deformation) material production, saw tooth after punching hole and made a good fly how to remove the burr hole around the edges and tooth equipment and the way equipment with the center point of grinding (also called the hole grinder) it? Using simple equipment on bench below to make a base fixed. Tooth points glitches, buy a serrated grinding machine or by hand with a look. Why aluminum blade cut piece burr is always king, get a new blade also has a glitch, there is some kerf side has no burr burr side?
  There are two effects:
  Material: Soft hardness usually aluminum sawing down after glitches obvious, so you aluminum materials and state is not too soft
 Sawing question: blade and cutting speed, cutting equipment usually used between 5000-6000 rpm, the problem is generally GISHI concrete diamond blades  estimated that the blade is a 9-inch alloy saw Bosch ,60-70 yuan a piece, very durable Gold Fields is also available. Of course, if the condition can also buy Bosch circular saws, one to be in the vicinity of 1,000 yuan, 2100kw Bosch's encroachment up pretty good, at least much better than Rui Qi. Of course, you can also choose metal band sawing machine sawing advantage of small incision, less waste, while the cut is not as smooth, the disadvantage is the high price band, a small range of processing.
