The PR Hoffman Servo RS 5400 Sapphire Lapping And Polishing Machine

After sapphire wafers are sliced, they need to be ground or lapped to a precision thickness before polishing. The PR Hoffman ServoRS-5400 model double-side sapphire lapping machine offers the largest processing capacity in its size-range machine while maintaining the necessary pressure {~3PSI = 210gm-per-cm²}.

The Servo RS 5400 sapphire polishing and lapping machine is part of the Servo RS family, specifically designed for the processing of thin and fragile parts. All Servo RS machines include computerized programming for unlimited 14-step recipes to enable processing of virtually any application. These machines also include a Windows-based PC operating system with user-friendly touch-screen input for unlimited storage and easy access to recipes and other technical resources as needed.

All Servo RS sapphire polishing and lapping machines offer precise pressure control, automatic plate flattening, speed and load ramping, and a retractable ring sprocket that allows for easy sliding of fragile parts off the edge of the plate, minimizing the possibility of damage.

The Servo RS series features 3-way motion for maximum precision. The 3-way motion offers numerous advantages over 4-way motion, including a solid lap plate base that provides greater precision than a rotating base and less complexity that reduces the need for costly maintenance.

The Servo RS 5400 is named for its 54-inch plate that makes it suitable for large, high-volume precision manufacturing applications like sapphire wafer polishing. This highly effective machine is also the top choice in manufacturing processes for industries such as silicon, semiconductor, optics and electro-optics.

Servo RS 5400 features and benefits include:
Extremely high production capabilities
Cutting-edge touch screen control and variable speed brushless DC servo drives
Sprocket tooth pin drive system for reduced carrier wear and lower operating and maintenance costs
High-quality design and construction for years of reliable service to your business
Automatic lubrication system
Low cost of ownership and unbeatable value
