We do mass de-burring of small copper hollow parts with stainless steel balls as media in vibratory machines( where parts and media are mixed , and the churning action moves parts and media). But the de-burring quality leaves a lot to be desired, as the balls do not knock off all burrs.
Any suggestions on getting better quality output ?? We tried cylindrical shaped media, but not much improvement . Non-spherical media tends to get stuck inside the parts.
Any tips on reducing burrs in cutting ?? we use circular sawblades,and the thickness we cut is 0.5 mm to 0.41 mm.
There is all different kinds of media to be considered. Some of the synthetic abrasive types might help. Although they break down and need to be replaced after a while.
As far as reducing the burr from the initial cut keeping the saw sharp and replacing it always helps, but no matter what you do there is always some burr. Carbide tipped?
*Describe section profile. Circular, as in tubing? *
Yes ! As far as reducing the burr from the initial cut keeping the saw sharp and replacing it always helps, but no matter what you do there is always some burr. Carbide tipped
We do regular sharpening and replacing .
No , our blades are Stainless Steel ( industry standard for our product ) , not carbide tipped !
Sharpness of cutting tool won’t help when pressure causes the material to yield . To avoid the problem, back-up is required. Perhaps the problem (burr) can be moved to the outside, where it can be dealt with more easily. May require tooling change.
Vibratory media/balls need be smaller than the most restrictive I.D. of course, but total effectiveness requires duration that may dimensionally affect parts i.e. akin to bellmouthing.
IME, an ineffective method of burr removal.
saw blade speed and the feed rate of the blade into the material, this can solve a lot of issues but may cause others, such as potentially lowering production rate and lessening tool life.
