Precision/Site Specific

The AD-5™ fluid dispenser provides automatic, unattended application of abrasive polishing suspensions and lubricants. Its functions are controlled through Allied’s MetPrep 3™, MetPrep 4™, DualPrep 3™ or MultiPrep™ systems, and can also be used with ANY brand polishing machine as a standalone system.

Timed, volume-controlled, variable frequency dispensing delivers reproducible results by eliminating inconsistencies between operators. This increases productivity and efficiency, while reducing consumables usage. Intuitive menu navigation and simple logic programming make the dispenser easy to use.

The AD-5™ features five (5) dispensing positions, two of which include a flush cycle to prevent clogging when using colloidal suspensions. Peristaltic pump technology offers mist-free drip delivery to the polishing surface.

The MultiPrep™ System enables precise semiautomatic sample preparation of a wide range of materials for microscopic (optical, SEM, FIB, TEM, AFM, etc.) evaluation. 

Capabilities include parallel polishing, angle polishing, site-specific polishing or any combination thereof. It provides reproducible results by eliminating inconsistencies between users, regardless of their skill. 

Dual micrometers (pitch and roll) allow precise sample tilt adjustments relative to the abrasive plane. A rigid Z-indexing spindle maintains the predefined geometric orientation throughout the grinding/polishing process. Digital indicators enable quantifiable material removal, which can be monitored real-time, or preset for unattended operation. Variable speed rotation and oscillation maximize the use of the entire grinding/polishing disc and minimize artifacts. Adjustable load control expands its capability to handle a range of small (delicate) to large samples.

A wide variety of fixtures and accessories are available for either 8" or 12" platen systems. The cam-locking interface offers tool-free attachment and removal for ease of use. Fixtures are precision machined out of high-grade aluminum (conductive) or stainless steel (corrosion resistant), then either lapped, heat or surface treated for maximum performance and durability.

The OptiPrep™ System is designed for production polishing of a wide variety of optical components including Ferrules, Connectors, Waveguides, Silicon V-groove, Optical Chips, Capillary/Glass Lenses, Fiber Bundles, Ribbon Fiber and Bare Fiber

Optical polishing applications rely on specific geometry. The OptiPrep™ features a fixed cam-lock interface reference that is parallel to the plane of the platen. Desired sample angles are obtained based on geometric orientation built into the fixture.

Z-positioning/indexing is displayed on the digital indicator with 1-micron resolution and can be pre-set for unattended operation. Variable speed rotation/limit rotation and oscillation with variable sweep maximize use of the entire abrasive surface.

Adjustable load control expands its capability to handle a range of small (delicate) to large samples.

Applications where the OptiPrep™ is used often require custom fixtures. Please contact Allied for assistance with a current fixture or to design and manufacture a fixture for a complete solution.

Allied offers a wide variety of standard fixtures, as well as in-house fixture design/manufacturing. The cam-locking system on the OptiPrep allows quick, easy fixture attachment and removal during the polishing procedure.
