MACHINES FOR THE MASS FINISHING PROCESS

Mass finishing is a surface finishing process used mainly for metallic workpieces.  When finishing bulk materials, the workpieces are placed inside a process drum together with a grinding or polishing medium and a normally aqueous mixture (compound). The oscillating or rotary motion of the drum creates relative motion between the workpiece and the process media. Heavy workpieces which can not be finished as bulk materials are processed in stream finishing or drag finishing machines.. In this machine type the workpieces are clamped in holders during finishing. With its well-equipped process development laboratory and state-of-the-art machines and technologies, OTEC has been delivering perfect results for mass finishing for nearly 20 years.

DISC FINISHING UNITS

For finishing the surface of bulk material. Wet or dry up to 20 times more efficient than e.g. conventional vibrators or drum systems. more

DRAG FINISHING UNITS

Workpieces are clamped in holders and dragged through a grinding or polishing medium. For polishing, grinding and high-precision edge rounding. more

STREAM FINISHING UNITS

Workpieces are moved through a stream of grinding or polishing medium, i.e. both the workpieces and the process drum rotate. The SF offers very short finishing times and can easily be automated or integrated into a production line.

TUB VIBRATORS

For finishing inlying surfaces much faster than with conventional tub vibrators. more
