National Torch has a line of flame polishing equipment to reduce the time and cost of polishing acrylic after machining operations. The National Model 3H oxygen / hydrogen torch is used with a variety of special tips to polish edges or through holes in acrylic or similar materials. The hydrogen and oxygen flame will not introduce contaminants into the material and the range of tips will allow you to polish stacked or solid materials up to 6 inches in width.
The RB Series tips are offered in lengths of 3/4″ (RB-0), 2″ (RB-22), and 6″ (RB-62). These tips are nickel plated brass and feature a swivel nut connection for 360 degree orientation on the torch elbow.
