[P]SUMMARY OF THE INVENTION[/P][P]SUMMARY OF THE INVENTION [/P][P] [/P][P]In accordance with the invention, a[url=http://www.gdgee.com/pipeline-equipments/pipe-beveling-machines-6337.html] pipe beveling machine includes a mandrel portion with ramps that move outwardly to engage a pipe s inner surface[/url]. A draw bolt attaches to an actuator having ramp receiving portions thereon, and as the draw nut is tightened, the actuator is pulled back by the draw bolt, causing the ramp portions to extend. [/P][P] [/P][P]Accordingly, it is an object of the present invention to provide an improved mandrel system that prevents pieces from falling off should the draw bolt break. [/P][P] [/P][P]It is a further object of the present invention to provide an improved mandrel system that is able to fit in smaller diameter pipes. [/P][P] [/P][P]A further object of the invention is to provide an improved backlash free wedge key engagement between a mandrel and the rest of the device. [/P][P] [/P][P]It is yet another object of the present invention to provide an improved [url=http://www.gdgee.com/pipeline-equipments/pipe-beveling-machines-6337.html]pipe beveling machine[/url] that reduces backlash. [/P][P] [/P][P]A further object of the invention is to provide an improved backlash prevention system that accommodates wear. [/P][P] [/P][P]The subject matter of the present invention is particularly pointed out and distinctly claimed in the concluding portion of this specification. However, both the organization and method of operation, together with further advantages and objects thereof, may best be understood by reference to the following description taken in connection with accompanying drawings wherein like reference characters refer to like elements.   [url=http://www.gdgee.com/pipeline-equipments/pipe-beveling-machines-6337.html]http://www.gdgee.com/pipeline-equipments/pipe-beveling-machines-6337.html[/url][/P][P]
