Deburr Both Sides
of Sheetmetal in
One Operation
Fabricators can perform double-sided deburring of metal sheets as thick as 0.2 in. thick in a single pass, with no addi- tional treatment, using the Rolei BE-5 deburring machine from CS Unitec, Nor- walk, CT. The machine operates at two speeds to enable fine deburring at 600
RPM or standard deburring at 1200 RPM. With standard 28-in.-long guide-rail extensions, or when placed on its side with roller tables, it can be used to deburr large, thin sheets.
In operation, two abrasive flap wheels rotate in opposite directions to grind both sides of the sheet as it passes through, deburring both edges simultaneously. The flap wheels can be easily adjusted as they wear—one set of wheels lasts for approximately 6500 ft. of stainless- steel sheet.
The machine is supplied standard with two 80-grit flap wheels, and can be used with optional grits (40, 60, 80 and 120) to suit the facet width and materials of a particular application. Accessories include a machine stand and a port for dust extraction.

   July 25, 2011 Are You Ready?
  Lincoln Electric offers a complete line of engineered solutions for weld fume control.
 • Are you welding metals containing cadmium, chromium, lead, manganese or nickel?
• Does your production operation include welding or other “primary processes”?
• Does your facility use 2,000 lbs. or more per year of welding rod containing one or more MFHAP*?
If yes, then the *Metal Fabrication Hazardous Air Pollutants - National Emissions Standard for Hazardous Air Pollutants Rule, 40 CFR Part 63 Subpart XXXXXX is important to
your company.
The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.
