I have a couple of vibratory finishing machines, the polyurethane lining is coming out of them and they need relining.
The smaller one has been knocking, took the bowl off and found the mountings had cracked the vibration through the cracks must have caused the knocking sound.
Bolted back up with large washers across the cracks and now works OK running silent as originally bought new. This is temporary repair, so called Invicta in Halifax to see about buying a new bowl. Was told by the salesman there that they kept no spares, and had not made this small machine for some years due to cheaper models coming in from Turkey.
Actually not a big job to make and new bowl, if I had a set of sheet rollers, and a bending press.
So to the point,
1 Who is importing these cheap vibrating bowls2 Anyone selling one? Auctions etc. Found these in auctions in the past with worn out bowls, have them relined and they work as new.
Mine are all troughs, not used the donut shaped round bowls, so don't know if they might be faster.
Deburring and polishing stainless steel.
Cheers
