DESIGN AND OPERATING FEATURES
The easily adjustable precision bearing surfaces pre-load and stabilize the rotating
head to provide long life, low maintenance, stability, and precision.
The Clamshell splits into four (4) quarters for mounting on closed loop systems.
All parts are secured to the four (4) quarters, thus avoiding the loss of parts and at
the same time providing maximum ease of handling.
The Clamshell is equipped with Adjustable Clamping Pads and Jackscrews for out-
of-round pipe conditions.
Dual Tool Blocks with Auto-Feed Sprockets and Adjustable Slides provide maximum
maintainability, life, and operator safety, with a minimum of operator training.
The Auto-Feed Sprockets provide .004” (.10 mm) of radial feed per revolution of the
Headstock for a controlled depth of cut.
The drive gears and bearing surfaces are covered for operator safety and are
shielded to provide protection from dust and chips.
The operator’s controls are located away from the rotating Headstock for the
operator’s safety.
