Mass Finishing Process Water, Part 2 – Maintain Adequate Drainage to Protect Your System

Numerous functions and calibrations factor into developing a precise and stable mass finishing process. From media and compounds to work piece characteristics and processing times, successful finishing requires each process aspect to be carefully monitored and evaluated. When it comes to process water flow rates, poor drainage from the machine can cause quality control issues as well as equipment damage and costly downtime.

While simple in their function, drains play an integral role in regulating the flow of process water out of the machine. With the exception of intentional “flooding” of the process bowl for sharp work pieces, the same amount of compound and water entering the machine must be flushed out again. Otherwise, contaminants in the form of dirt, media, metal fines, and, frequently, oil will accumulate in the process water. Since this buildup can cause the finishing process to deteriorate and even collapse, mass finishing machines must have sufficient drainage!

Machine Features

Most mass finishing machines, including rotary and tub vibrators and drag‐, plunge‐, and surf‐finishers have special drainage screens built into their work bowls. High-energy centrifugal disc finishing machines differ since the “dirty” process water is evacuated through the gap between spinner and work bowl.

Drain types used in rotary vibrators.

Made from plastic such as polyurethane or stainless steel material, these drains must allow process water and media debris to be flushed from the system while retaining usable media mix and the work pieces.

Mass Finishing Tip 4. Regularly Check Your Drains

Drains allow the process water, particles and any contaminants to be carried out of the bowl so the process can operate and perform to its optimum capability consistently. Depending on the Mass Finishing Machine Tips Booklet_Page_3_Image_0002process if unchecked drains can get blocked. Once this happens the water level in the bowl will increase, with compound added this can create foam (and mess) and the process time and surface finish will again suffer as a result. If the quantity of particles in the bowl is high then this can contaminate (and even ruin the media) as well as coating the lining of the bowl causing a loss in drive of the media.
