ABOVE: Constant Centerline Roll. This is a drawing of our RD-10-INW Tank Turning Roll . Constant Centerline Rolls provide the user with an infinitely variable roll to roll center distance by lead screw adjustment on both the drive roll and idler roll. This allows for adjustment that allows constant roll to roll center distance. As you can see above with different diameter work piece sizes the centerline always remains constant.
BELOW : Standard Roll. The below drawing shows our EX-R10-A Tank Turning Roll . With a standard turning roll one roll is fixed. Because of the one fixed roll when the work piece diameter size changes the centerline will not remain constant as noted in the image below.
