Trovalizing
Trovalising uses the cylindrical motion of a vibration tub containing
the workpieces, grinding media/pellets and water. The vibration and
water, smooth the edges of the machined parts and give the surface
a uniform structure
Advantages:
- Quick and inexpensive
- Edges are rounded
- Uniform structure of the surface
- Avoids inefficient manual work
Vibratory grinding
Vibratory finishing involves the workpieces along with ceramic,
plastic, or metal and an additive (compound). The tub is then
agitated with an unbalanced motor and the rotary oscillation
movement causes removal of material from the workpiece.
