The NCRx Cribber is a standalone, manually operated, machine that is intended to easily and accurately reduce the diameter of the lens blanks. It uses a 20 mm ball mill, driven by a high-speed 2+ horsepower motor, which removes the unneeded material on the outer diameter of the lens blank.
With his small benchtop footprint (see specification) and standard power requirements, just plug it in and you’re ready to go.
The cribber is first adjusted to the crib diameter needed by moving a stop position to the desired diameter. The indicator allows adjustment to within 0.5 mm. The vacuum system is then energized (not provided). A blocked lens is then simply placed into the chuck, tightened, moved into the cutting area, and then driven into the ball mill at the adjusted diameter. The only motion electrically driven is the ball mill.
Even when cutting large polycarbonate blanks the job is done in less than 10 seconds. Having pre-cribbed lens blanks provides several advantages.
• Reduces cutting time on surfacing machine.
• Increases the tool life on surfacing machine.
• Reduces number tool changes on surfacing machine.
• Increases the life expectancy of the surfacing machine.
• Reduces number of lens design rejections.
The cribber may also be used to reduce the diameter of lenses prior to edging. This reduces the wear and tear on edging machinery and improves edging time.
Finally a low-cost, simple to operate, tabletop machine to take lens blanks down to size in seconds.
