An undesirable pattern created on the surface of a workpiece, usually at regularly spaced intervals, caused by an out-of-round or out-of-balance condition. Chatter marks are not a structural defect, but they cannot be corrected or eliminated once they are in the material; the marks will usually show through any paint that is applied.
CS Unitec: PIPE-MAX Belt Grinder
The PIPE-MAX is a combination grinder and pipe belt sander. The front hard rubber contact roller drives the abrasive belt to grind flat surfaces. It removes weld seams in a straight line, without leaving edges or a wavy finish. For sanding pipes or handrails, the sanding belt follows every contour to grind and polish up to a high-gloss finish. Ideal for stainless steel, aluminum and high-quality metals.
