INTRODUCTION TO OPERATION
The patented Horizon II is a router-type edger for plastic lenses which dry cuts all plastic lenses,
including Polycarbonate, to shape and size, rather than grinding them with diamond wheels. Its fully automatic
cutting operation can apply any one of four standard finishes to the periphery: a hide-a-bevel, a modified 5
hide-a-bevel, a rimless edge, and a groove. With the addition of specialty cutters, the Horizon II can also apply
other finishes with a degree of precision not found on many conventional edgers, including a roll and bevel, a
facet, a safety hide-a-bevel, and a shelf for snap in frames. All powers and sizes of lenses are edged in the same
cycle time of less than 1 minute, except faceting and shelved jobs, which require two cycles.
Lenses are cut with a cutter 3/4" in diameter with a single carbide insert. The cutter is driven by a
brushless DC motor at 15,000 rpm. The various edge finishes are formed with different cutters, which can be
changed in less than a minute. Removed material is sucked into a dry vacuum unit and therefore no coolant is
needed. The resulting debris is comprised of inert material, and can be
refuse.
Two tracking systems are supplied. With the first, a white Teflon bevel guide wheel accurately tracks
the actual front of the lens. With the second, a bevel is placed on the lens by following a pre-determined base
curve of 2, 4, 5, 6, 7, or 8, through the use of cams. Changes between tracking methods can easily be
accomplished in 30 seconds.
Size and bevel placement adjustments on the Horizon II are made with dials found outside of the unit's
case. Due to the unique design, the operator can clearly observe the entire edging cycle from start to finish.
The option is also available that enables the operator to control finish bevel (or groove) placement after the lens
is roughed into shape, allowing for greater precision. Pattern-from-a-pattern and pattern-from-a-lens
duplication are also standard features.
The Horizon II is supplied with standard air-chucking for both the pattern and lens. In addition, the
sophisticated pneumatics of the unit make it possible to adjust the pressure of the pattern against the pattern
roller when utilizing thin lab-made patterns, or demo lenses. The system also provides a pressure adjustment of
the bevel guide wheel against the lens, enabling the edger to track even the thinnest lenses with total accuracy.
The Horizon II edger is designed to edge plastic lenses only. Any other use of the
machine will compromise its safety protection features. Under no circumstances should any
attempt be made to edge a glass lens on this unit!
THE HORIZON II WILL EDGE ONLY PLASTIC LENSES.
