ROUND BOWL VIBRATORY MACHINES
“Vibratory Deburring” is also referred to by its original engineering term: “Mass Mechanical Surface Finishing.” But what is it, and how do you get started?
Mass Mechanical Surface Finishing is the term for processing bulk quantities of parts simultaneously to generate a safe edge, radius or a specific RA or RMS surface profile.
Let us explore some of the more standard machines and methods.

WE SELL THE SYSTEM, INCLUDING ROUND BOWL VIBRATORy MACHINES
From running single parts, batch processes or continuous system setups for automatic production, versatility is here. Take advantage of internal separation of parts and media (media falls through screen openings and parts exit machines) and continuous setup for once-around-and-out applications where the part(s) need to be washed or Rust Preventative applied.
The Round Bowl can be set up with timers to automatically unload/separate while no operator is present.
Kinetic energy is the driver for the action or motion in the bowl, with roll and progression. This is from the machine vibratory assembly (motor, shaft and bearings). The round bowl splits the energy two ways: roll and progression. This is all adjustable depending on the process and results required.
No matter the style of vibratory deburring equipment, the more you see the parts, the less work is being done. Burr removal is critically important because it directly affects the performance and reliability of the parts.
Round bowl units run a more gentle process for a finer surface profile and can eliminate scratches due to part on part contact like in the tub style.
The rotation of mass is set up through the aggression of the process. Progression is used for gentler processes and needed for good internal separation. We recommend using a sample part processing to find the right rotation. There are many variables with tumbling media, part sizing and screening.

HIGH-ENERGY ROUND BOWLS FOR FASTER TIME CYCLES AND UNLOADING ADVANTAGES
Almco offers a High-Energy (HE) Bowl Series featuring shorter cycle times and increased action when production dictates. “HE” Series bowls have design efficiencies and multiple advantages:
- High-impact vibration with increased amplitude control of both upper and lower counterweights
- Two-dimensional control of both impact stroke and mass progression
- New concept “Mass Roll” with strategic parts positioning
- Parts/media unloading efficiency via high-energy mass rotation and action
- Steel media parts processing and unloading capability
