The Optek Criterion MAX is the third generation of Optek's landmark Criterion Digital
Surfacing Cell, the world's first microprocessor-controlled finer/polisher.
Based on the industry-leading mechanical design of the Optek 429, Criterion MAX
extends this technology by using state-of-the-art PLC control to simplify operation,
reduce operator decision-making, and increase quality. When interfaced to Rx calculation
software, the operator simply enters a job number, and Criterion MAX automatically
optimizes spindle speed, pin pressure, and cycle time.
- Enclosure is constructed of heavy duty gauge sheet metal — no injection
- Timed gear belt drive mechanism minimizes vibration and prevents motion
irregularities during processing.
- Extended life bearings feature a special reservoir for adding additional
- Double baffle system with tertiary internal drip shield protects internal
- Ergonomic design features a oversized chemical resistant slurry bowl.
- Foot pedal controlled, pneumatic lap clamping.
- Slurry system accommodates either standalone or central slurry solenoid
with hookups at the rear of the unit. Standalone system stores slurry in reservoir
separate from pump to avoid overheating the slurry.
- Orbit and sweep range adjustments are made internally to prevent accidental
- Wide range of sphere and cylinder curves support both plus and minus surface
- Patented motion provides true axis control.
- Slurry temperature monitoring system warns the operator if the slurry temperature
falls outside the optimal range for the lens material being processed.
- Vacuum lens loading system speeds operation and reduces breakage from block
and pin misalignment.
- Slurry pre-flood system speeds and simplifies operation by automatically
flooding pads with slurry prior to cycle start.
- Multi-material processing feature automatically establishes optimal cycle
parameters using the onboard material database (manual mode) or via download
from Rx processing software.
- Auto speed ramping feature ramps spindle motors up to operating speed. This
reduces pad separation from lap during start up, especially with helpful gripper
- Dual pressure clamping system starts the cycle at reduced pin pressure and
then increases to full pressure for the duration of the cycle. This is especially
beneficial when processing glass or lenses produced on conventional diamond
wheel generators (optional).
- Variable speed control allows the operator to establish a min/max RPM range
for spindle motor operation(optional).
- Auto reversing motion (optional).
- Automatic mode — Serial interface allows job data to be downloaded from
Rx processing software by job or tray number.
- Manual mode — Stores parameters for four materials in the onboard database.
- Maintenance advisor records running hours and prompts the operator when
scheduled maintenance should be performed.
- Large LCD display provides easy viewing.
- Sealed membrane keypad protects electronics from moisture.
- Barcode reader (optional)
- Ethernet interface capability for larger labs (optional)
- Size: 21" W • 30.5" D • 54.75" H
- Weight: 335 lbs
- Power: 120V, 15A, 60Hz, 1~ (other voltages available)
