Machine Mounted Roll Calipers for Two Wheel Roll Grinders

The RollTrack® measuring device is designed for, and mounts on existing Farrel two-wheel roll grinders. The special
design features two measuring gauges in brackets/levers mounted on the covers of the wheel guards of the roll grinder. The gauges traverse the length of the roll body on the carriage thus being able to measure and record the geometrical characteristics of the roll over its entire length, and at any fixed location but with the roll rotating.

The measuring device records, displays and provides a hard copy of the measurement in the form of a graph representing continuous measurement over the length or circumference of the roll. The results can be sent to computerized controls to modify a bed correction curve automatically.

The measurement graph displays the nominal or base measurement parameter (zero-line, cosine crown, or compound crown target) and tolerances. The system provides reports on the following measurement modes:

– Two point straight profile measurement.

– Two point crown measurement.

– One point eccentricity measurement.

– Two point concentricity measurement.

– Two point roundness measurement.

Special measurements such as sag, roll alignment, straightness of ways and T.I.R. in other positions are possible using standard modes. Resolution of the measuring system is selectable .0005", .0001",.000020", 0,01 mm, 0,001 mm or 0,0005 mm. A special high resolution model is available at .000004" (0,0001 mm) resolution.

The RollTrack® recording system provides report display and hard copy capabilities. The graph is displayed while measuring (profile and crown) or immediately after (T.I.R. and roundness) a measuring pass. The reports also include manually entered or previously saved roll data. There is adequate memory space for saving the reports on a hard disk, up to 1000 roll numbers and 1000 reports on each roll.
