A colorized and tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer in combination with at least one tribological modifier. The tribological modifier may include a fluoropolymer. The polymer composition further contains at least one coloring agent in combination with a color stabilizer. The color stabilizer has been found to dramatically improve color consistency. Polymer articles molded from the polymer composition not only have excellent surface appearance but have excellent low friction characteristics when tested against aluminum.

A deburring apparatus includes (among other components) a frame and an elongated flat element connected to the frame. Rollers are adapted to support and rotate a vacuum belt around the apparatus. A perforation device is positioned and adapted to make perforations in the vacuum belt as the vacuum belt is rotated by the rollers. Making the perforations in the vacuum belt causes debris to remain in at least one of the perforations. The elongated flat element is positioned to contact the debris in the perforations.
