Servo Control

Viewing video requires access to YouTube.

The RollTrack® servo system controls the tilt infeed of a wheelhead to grind a roll with straight or crown shape, and to compensate the paths of consequent grinding passes from a roll measurement.

The FMT RollTrack® servo control system installed on the left side of the above Farrel two-wheel roll grinder.

The RollTrack® Grinder option is an additional option to the RollTrack® measuring program including features:

 

• Setup for grinding.
• Set roll grinding parameters by existing controls (roll and wheel speeds, traverse), or RollTrack® option.
• Open the RollTrack® Grinder menu and select Grind Profile (straight) or Crown.
• Set total crown, angle, and length.
• Capability for off center crown or secondary crown targets.
• Set continuous infeed as needed.
• Set end infeed as needed.
• Set taper correction as needed.
• Capability to dub roll ends (grind taper).
• The servo infeed is activated by the carriage position.
• RollTrack® computes the current crown height at each station.
• RollTrack® checks the reference gauge and moves the servo in or out to make the wheelhead match target height at the location.
• If an intermediate measurement is done on a roll, the measuring results can be applied to the control program to correct the grinding wheel path accordingly.

RollTrack® touchscreen is added to the main control panel.
