Machine mounted roll caliper:

One (1) lot of measuring equipment to measure various geometrical features of rolls ground at your site.  The measuring device is designed for, and mounts on, an existing Farrel two-wheel roll grinder.  The special design features two measuring gages in bracket/lever assemblies mounted on the wheel guards of the roll grinder.  The gages 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 graph also displays the nominal or base measurement parameter (a zero line, cosine crown, or compound crown target) and tolerances. The device provides reports on the following measurement modes:

Two gage straight profile measurement

Two gage caliper tracking measurement

Two gage crown measurement

One gage TIR/concentricity measurement at 3 and 9 o'clock

Two gage two plane concentricity measurement

Two gage roundness measurement. 

Special measurements such as sag, roll alignment, machine ways, and T.I.R. in other positions, are possible using the standard modes, too. The resolution of the display system can be set to .0005", .0001", .00001", 0,01 mm, 0,001 mm, or 0,0005 mm. Gage head resolution is .00004", .00002", or .000004" depending on the model.

The recording system is PC based with report display and hard copy capabilities. The graph is displayed during measuring (profile and crown) or immediately after (T.I.R. and roundness) a measuring pass. The reports also include entered or previously saved roll data. There is space in the software program for saving the reports on a hard disk, up to 1000 roll numbers and 1000 reports for each roll. Cabling is required via the cable carrier of the roll grinder.

The measuring and recording system is the RollTrack® model 2G1E and it consists of:

1. Two mounting brackets/levers for the Farrel two wheel roll grinder. Contact point distance from the cover face of the wheel guard towards the wheel center is 4". Vertical adjustment for above grinder center line measurement is 5".

2. Two photo electronic gage heads.

3. Two each barrel and ball type measuring contacts.

4. One distance encoder w/bracket & wheel.

5. Three signal cables from gage heads to PC. Specify length.

6. Software license to use RollTrack® software at one measuring location on one PC system. 

7. One PC interface board.

8. One PC system with Windows XP.

9. One SVGA color display.

10. One color printer.

11. Set of manuals.
