Customers often consult with us why they vibratory polishing out the product parts black, not bright or was drunk ... ...
through the understanding found that: they use the improper vibratory media or finishing machinery, for example, a
luggage hardware customers, his products are zinc alloy die castings, he used corundum grinding stone to mill, the results more grinding more black; there is a stainless steel round gasket, the use of vibration grinding machine to the front , In the grinding process, there are a lot of gaskets overlap together, the poor rate of high ... ... these phenomena and they did not deal with the three elements of vibratory finishing is closely related, what is vibratory polishing three elements? That is, vibratory polishing machines, workpieces, grinding media, only the three useful with, in order to play a multiplier effect, the following three elements were a simple analysis:
1).vibratory polishing machine
In the surface treatment, the commonly used mechanical vibrating polisher, drum-type polisher, centrifugal polishing machine, eddy-flow polisher, which in turn vibratory polisher and drum-type polisher the most widely used. Vibratory polisher is easy to operate, for a variety of parts of small, medium and large quantities of processing; drum type polisher is an economical grinding and polishing machine, spare parts and grinding media in the closed drum Rotating, slower, commonly used in small size, thin parts of the various parts, especially those large parts of the plane, the use of vibrating polisher processing easy to overlap, more suitable for drum-type polisher; centrifugal grinding machine The actual is the high-speed drum-type polisher, it is generally driven by the four (minicomputer also has two) centrifugal polishing barrels high-speed rotation, friction, polishing effect is good, commonly used in vibrating polisher, drum Vortex machine is also a high-speed polishing machine, through the chassis rotation, the formation of a strong over-current friction movement, for small parts to the front, to glitches, polishing.
Different parts of the material, different specifications of the parts, different requirements of the parts, also requires a different machine and grinding media. For example, die-casting of zinc alloy pieces need to go to the scale, should be used resin grinding stone; and stamping out of the stainless steel parts need to go to the front, to deburring, then it should be large cutting force corundum grinding stone ... ...
3) finishing media
vibratory finishing media, including grinding stone, polishing stone, abrasive, gloss agent grinding and polishing materials, each material has its own application, such as plastic grinding stone for materials such as soft materials, such as aluminum, zinc, copper, plastic, etc. ; Ceramic grinding stone for hard materials, such as iron, stainless steel, white iron, steel, etc .; polishing material for the iron parts, need to use iron luster agent, polished material for copper parts, need to use copper gloss agent , Hand tools, cutting tools for all kinds of wrenches, sleeves, approved Tsui to black film, to oxide, if used for other parts, will likely corrode, destroy parts ... ...
In general, only a full understanding of the three elements of grinding performance, characteristics, can effectively match, to achieve a multiplier effect
