MultiPol Automatic Grinder and Polisher

MultiPol is a fully automatic metallographic grinding and polishing system engineered for high-load and high-repeatability industrial preparation environments. The system features a central loading mechanism, enabling controlled and quantitative material removal with a removal accuracy of up to 0.1 mm. This ensures stable preparation conditions for reliable microstructural analysis.
Equipped with a 6-channel automatic dosing system, MultiPol provides consistent consumable distribution throughout the preparation cycle, supporting uniform surface quality and process stability. The system is compatible with φ250mm to φ300mm platens, offering flexibility for diverse specimen sizes and preparation requirements.

Features

1. Advanced Process Control for Maximum Repeatability

MultiPol integrates automated control of critical preparation parameters, including applied load, platen speed, rotational direction, and processing time. By eliminating operator-dependent variations, the system ensures controlled and repeatable material removal throughout each preparation stage. Predefined preparation methods can be executed via single-command activation, guaranteeing consistent process conditions across batches, operators, and production shifts. This significantly enhances reproducibility and supports reliable microstructural evaluation.

2. Process Documentation & Standardization

MultiPol integrates automated control of critical preparation parameters, The system enables structured documentation of preparation parameters and process data, including: Specimen holder configuration; De fined preparation methods; Consumable dosing parameters; Individual process step duration; All parameters can be stored and recalled, facilitating standardized preparation protocols and ensuring long-term process stability. This structured process control supports laboratory quality systems and provides a foundation for traceable, validated sample preparation workflows in industrial and R&D environments.

3. High-Throughput Processing Capability

MultiPol adopts a synchronized drive structure combined with an integrated cleaning program, reducing cycle time between preparation stages. The system accommodates up to 8 specimen holders per batch, enabling simultaneous processing of different specimen types and improving preparation throughput while reducing the likelihood of rework.

4. User-Oriented Interface Design

The automatic dosing system features a visual monitoring layout and quick-connect structure, allowing real-time observation of consumable levels and efficient replacement. The fully automated operation minimizes manual intervention, enabling rapid setup and operation without extensive operator training, while maintaining controlled and consistent preparation conditions.
