Improving the efficiency of tube end finishing FOR manufacturers of tubing products, or those who manufacture products with tubing components, Severance Tool, based in Michigan, USA, has developed a line of tube end finishing rotary tools which can deburr, form or chamfer as required by different application needs. The tools are designed to finish both the inside diameter and outside diameter of tubing ends in a single operation and feature adjustable, two-piece construction to accommodate work on the same size tubing with varying wall thickness ranges. Other features include, depending upon application, Chatterless™ tooth geometry that alternates tooth cutting angles to eliminate resonant vibration from the tool and work piece for smooth finishes; and Severance’s exclusive Grayhone™ finish that provides cutting edges ready to work with no break-in period required. Among the tools offered is a full line of tube deburring tools available in high speed steel or carbide construction. These tools, although they provide a 30° inside chamfer and a 45° outside deburring, are designed for light duty – to break sharp edges of both the inside and outside diameters simultaneously. They feature tooth geometry with a shearing cutting action for fast cutting that prevents loading of chips. These tools can be reground numerous times for long service and operate in speed ranges of 50 to 200 RPM. The outside ring or member is adjustable, secured by screws, to provide various outside edge break sizes and compensate for different wall thickness within a given tube diameter range. Tube deburring cutters are available in standard sizes for 1 / 8 "outside diameter ( 1 / 16 " inside diameter) through to 2 1 / 4 " outside diameter (2" inside diameter) tubing and with a variety of shank styles. Tube end chamfer mills provide the same shear cutting action and outside ring. These are as adjustable as the deburring cutters, plus with Chatterless™ angle geometry is designed for heavy duty cutting to machine precise, smooth 45° outside diameter and 30° inside diameter chamfers in applications requiring easy assembly with other components. Chamfering mills are available in sizes for pipe and tubing ranges from 3 / 16 " to 2 1 / 2 " outside diameter. For all three types of tube end finishing tools, standard sizes are typically shipped with same-day services. Severance Tool Industries Inc www.severancetools.com
