Difference between revisions of "Mandrel Lube"

The lube feature is only available inside the Bend Option cells of the FRB menu. This allows an operator to control mandrel lube for each bend.

Use the Mandrel Lube Enable to switch the feature on or off.

This feature works with the Mandrel Lube Start and Mandrel Lube Stop angle settings. These control the start and stop of the mandrel lube based upon the bend angle.

The start angle refers to where the lube zone starts: The values is from 0 degrees.

The stop angle refers to where the lube zone ends: The value is an angle that is subtracted from the FINAL ANGLE.

For example, if you set the stop angle to 50 degrees on a 50 degree bend, then the mandrel lube will never start - because CNC Bender is told to stop the lube 50 degrees below the goal - which is 50 minus 50, or 0 degrees.

The "stop within" value is always relative to the final bend angle so that if the start and stop values are set to ZERO, then the operator can know for sure that the ENTIRE bend is lubricated - even when the bend angle is adjusted.

We believe that, after the setup technician becomes used to this standard, this makes setup easier.

If...

• the bend angle is 50 degrees
• the "start angle within" value is 10 degrees
• the "stop angle within" value is 10 degrees

...how many degrees of bend will the mandrel be lubed?

Answer: 30 degrees

Reason: The lube starts at 10 degrees and stops at 50 minus 10 degrees. So 40-10 = 30 degrees of lube.

If...

• the bend angle is 75 degrees
• the "start angle within" value is 0 degrees
• the "stop angle within" value is 0 degrees

...how many degrees of bend will the mandrel be lubed?

Answer: 75 degrees

Reason: The lube starts at 0 degrees and stops at 75 minus 0 degrees. So 75-0 = 75 degrees of lube.

If...

• the bend angle is 90 degrees
• the "start angle within" value is 0 degrees
• the "stop angle within" value is 90 degrees

...how many degrees of bend will the mandrel be lubed?

Answer: None

Reason: The lube starts at 0 degrees and stops at 90 minus 90 degrees. So 0-0 = 0 degrees of lube.
