Glassmaster 720 Benefits
The Syncroshaft Advantage
The patented Syncroshaft carrier ring drive system accurately synchronizes the rotation of all three carrier rings, ensuring consistent flatness and finish between all work stations. This is accomplished by utilizing the rotating motion of the polishing table to drive the workstation carriers. The design is extremely straightforward and dependable, eliminating the cumbersome controls, wiring and motors that commonly fail on conventional carrier drive systems. The Syncroshaft system is designed to be virtually maintenance free.
Superior Table Design
The Glassmaster 720’s polishing table sets an industry standard for rigidity and stability. Consistent flatness tests of 1/20 to 1/30 of a wave length can be expected. The one-piece granite polishing table weighs in at over 2,000 lbs to ensure maximum rigidity and zero flex. The table rides on a heavy duty, 30 inch diameter angular contact bearing, providing smooth and precise table rotation and lasting durability. A polished stainless steel recovery tank surrounds the whole arrangement, neatly guiding the polishing solution back to the steel reservoir and effectively protecting the table bearing from dirt and moisture.
Robust Drive Components and State-of-the-Art Controls
The polishing table and syncroshaft system are powered by a heavy duty, five-horse power AC motor that drives two highly durable oil bath gear boxes. Together, they allow for extremely heavy workloads to be polished. The drive motor is controlled by a user-friendly, fully programmable AC power inverter, which has the capability of operating on 480 volts three phase electrical power.
Motor control features include:
- Variable speed control
- Preset speed
- Ramp start
- Motor load
- Full LED readout
- Forward and reverse jog
The Glassmaster 720’s open air power drive compartment enhances cooling, allows for easy component inspection and simplifies lubrication maintenance tasks. The motor controls are state-of-the-art. All the components in the power drive system are specified at two and a half times the normally calculated service factor required to drive the machine, allowing it to be operated 24 hours a day on a continuous basis.
High Versatility Work Station
Because of Glassmaster 720’s unique work station design, there is no vertical obstruction over the carrier rings, allowing work of any height to be polished. Each carrier ring position is adjusted by a threaded scissor assembly, which allows quick and easy carrier movement without reaching over the polishing table. This feature greatly reduces the possibility of contaminating the polishing surface or slurry solution.
Each work station accepts carrier rings ranging from 16-36 inches diameter. Carrier ring positions are quickly and easily adjusted by simply turning a handwheel.
