A portable boring/facing machine using a single drive motor for rotating a boring bar and for either axially translating a cutting head assembly along the bar or radially moving the blade of the cutting head assembly using a lead screw. The machine utilizing two mounting brackets is attachable to the workpiece for alignment with the workpiece.

Radial feed facing head for boring bar

The present invention relates to a grinding apparatus for grinding an out-of-round trunnion tire for a rotating kiln. The present invention is mounted on a trunnion roller such that a tracking wheel and a grinder are in tangent with the out-of-round trunnion tire. The mounting bracket supports a means for angling the grinder so that it is in tangent with the out-of-round tire and making it round. The grinder is part of a grinder head assembly which is mounted on the angling means. The grinder head assembly includes the grinder, a housing and a drive mechanism. The drive mechanism includes a motor which drives the grinder wheel so that it grinds the trunnion tire back into round.

Grinding apparatus for grinding an out-of-round trunnion or tire for a rotary kiln

A kiln tire grinder for grinding an out-of-round kiln tire comprising a grinding belt head assembly having a rotatable grinding belt and an x-y positioning table for positioning the rotating grinding belt assembly against a kiln tire. The rotating grinding belt assembly includes a drive assembly for rotating the grinding belt and a frame assembly for urging the grinding belt against the out-of-round kiln tire. The operator adjusts the rotating grinding belt head assembly against the out-of-round tire and then engages a drive motor which rotates the grinding belt. The rotating grinding belt is then urged against the kiln tire with a pressure that is adjustably controlled.

Rotating kiln tire refinishing machine

A portable boring/facing machine having a rotatable boring bar on which is supported a cutting head assembly that is adapted to be axially translated by a lead screw drive powered by an AC variable speed servo motor is provided with mounting brackets attachable to the work piece that incorporate a swivel mechanism for facilitating alignment of the boring bar with the centerline of the work piece.

Portable boring/facing machine

A tube saw for precision cuts on tubing wherein a motorized circular saw is rotated about the circumference of a tube to cut it without leaving burrs, finishing marks or other deformations on the tubing. The tubing is held firmly and precisely by a plurality of facing triangular clamping elements and the clamping elements are centered and firmly locked in place relative the housing containing the saw to ensure the blade does not move relative the tube during the cut. The housing, rotatably holding the saw, has bearings with angular and radial stiffness to hold the saw firmly in position during the cut to ensure a high quality cut. A servomotor drives the rotatable portion of the housing at an even rate to cut the tubing with an even force and rate around its circumference. The saw is positioned close to the end of the clamping elements to limit bending and vibrations in the tubing from interfering with a square high precision cut. A radial feed control on the rotatable portion of the saw housing adjusts the radial displacement of the saw for cutting into the tube. The tube saw can be used on small tubing with high precision as well as larger tubes. The ability of the tube saw to hold the position of the tubing and the saw blade precisely while limiting vibrations in the tubing an the saw blade contribute to the high quality square cut provided by the tube saw.
