This all-in-one unit completes the full preparation sequence: pre-grinding, rough grinding, fine grinding, rough polishing and fine polishing without switching across separate devices. It adopts a dual-disc single-control architecture, giving operators flexible speed management with both stepless variable-speed adjustment and four preset constant-speed modes for standardized lab recipes.
Operators interact with an intuitive LCD digital display control panel. All key parameters including disc rotation, head speed, processing time and pneumatic loading pressure can be set directly on-screen, lowering training barriers for new lab technicians.
The working platens receive precise fine-grinding and surface finishing during manufacturing, which guarantees flat specimen surfaces and reduces scratch artifacts on finished samples. For long-term onsite use, the machine housing uses high-strength fiberglass-reinforced plastic through integral molding; this structure resists splash-related corrosion and delivers outstanding mechanical durability for heavy-duty daily operation.
Core functional highlights recap

- Dual-disc single-control system with stepless speed plus four fixed constant-speed settings
- User-friendly LCD screen for quick parameter programming
- Precision-finished work discs to keep specimen surface flatness stable
- One-piece high-strength fiberglass housing for corrosion resistance and long service life
Typical Application Scenarios
The iPoli-2S-250A dual-disc automatic grinding polishing machine is widely deployed for routine quality-control testing, material science research, and component failure analysis. It features strong motor output, low operational noise, solid mechanical build, and straightforward operation — making it a preferred piece of metallographic lab equipment for manufacturing enterprises, university material labs, and independent scientific-research institutions.
Users prepare metallic alloys, castings, electronic component cross-sections and other specimens for subsequent metallurgical microscopy inspection. Its single-force pneumatic loading mode applies uniform pressure across the batch of clamped samples, minimizing result deviation caused by human manual-operation variability.
Key Technical Details of iPoli-2S-250A
To help buyers evaluate whether this unit fits their lab requirements and sample-size limits, here are the complete technical specifications integrated into text.
Officially named Auto Metallographic Grinding Polishing Machine, the model is iPoli-2S-250A (Single-Force Dual-Disc). Its standard polishing disc diameter is Φ250 mm, with customizable options for Φ230 mm or Φ300 mm platens upon request.
For disc rotation, users get stepless adjustment ranging from 50-1000 rpm, alongside four built-in constant-speed presets at 400 r/min, 600 r/min, 800 r/min and 1000 r/min. The grinding disc rotation direction is fully switchable between clockwise and counter-clockwise. The grinding head supports stepless speed regulation from 5 rpm up to 150 rpm.
As for sample holding capacity, the machine comes standard with 6 sample holders, and can be customized to hold 4 holders if your batch size is smaller. The pneumatic loading pressure is adjustable from 0-0.7 MPa, while the factory default parameter is preset within 0.2 MPa. Operators can set sample preparation running time anywhere from 0-3000 seconds to match different material processing needs.
In terms of specimen dimensions, the machine accepts standard Φ30 mm polishing samples; a custom clamping range of Φ22-Φ45 mm is available for non-standard specimens.
Power input runs on AC220V 50Hz mains supply with rated power reaching 900 W. The overall physical footprint measures 755 × 815 × 690 mm (corrected the original document typo of 6900 mm). Net weight of the unit stands at 89 KG, while the gross shipping weight comes in at 113 KG.
Multiple custom options are supported for disc dimension, holder quantity and specimen-clamping range to accommodate unique specimen sizes and different batch-processing volumes in various labs.
Who Should Consider Buying This automatic metallographic grinder polisher with dual platen?
- Quality-control labs handling medium-volume metallurgical inspection batches
- Material-science research teams needing programmable, repeatable grinding polishing cycles
- Facilities that want to reduce human-driven inconsistency from fully manual sample preparation
- Users who require flexible customizations for non-standard specimen sizes
If you are currently struggling with inconsistent manual polishing results or hope to standardize your metallographic sample preparation process, the iPoli-2S-250A offers a balanced combination of automation performance, mechanical robustness and configurable parameters.
