Precision Metallographic Sample Preparation with Mikrosize Manual Grinding and Polishing Machines
In the fields of material science, metallurgical analysis, and industrial quality control, the preparation of metallographic specimens is a critical step that directly influences the accuracy of subsequent microscopic examination and testing. As a trusted Measuring Testing Instrument supplier, Mikrosize offers a comprehensive range of manual metallographic grinding and polishing machines designed to deliver consistent, high-quality surface finishes across a wide variety of materials. From the entry-level iPoli-D series to the more advanced MPoli-250M/300M series, these instruments are engineered to meet the demanding requirements of metallographic sample preparation in laboratories, research institutions, and production environments worldwide.
Robust Construction and Intelligent Control
The Mikrosize MPoli series represents a significant advancement in manual metallographic grinding and polishing machine design. The machine body is integrally formed with high-strength ABS material, offering excellent corrosion resistance and long-term durability. At the heart of the system is a 7-inch high-definition LCD touch screen that provides intuitive control over all operational parameters. Users can easily adjust the rotation speed through stepless speed regulation ranging from 50 to 1000 r/min, or select from four pre-set fixed speeds for routine applications. The rotation direction is fully reversible, allowing operators to switch between clockwise and counterclockwise rotation at any time to accommodate different grinding and polishing requirements.
Advanced Drive System for Consistent Performance
Powering the MPoli series is a high-performance servo motor that delivers low-noise, high-torque output across the entire speed range. This servo-driven system ensures constant power delivery even at low speeds, eliminating speed lag and maintaining ultra-smooth operation—essential for producing defect-free specimen surfaces. The transmission system incorporates precision components that guarantee stable and repeatable results, whether performing coarse grinding or final fine polishing. Available in both single-disc (MPoli-1) and dual-disc (MPoli-2) configurations, with disc diameters of 254mm or 300mm, these machines can handle a broad spectrum of sample sizes and throughput requirements.
Innovative Disc Management and Cooling Systems
A standout feature of the Mikrosize metallographic grinding polishing machine is its magnetic disc system. Equipped with a magnetic platen and Teflon non-stick discs, operators can achieve rapid, tool-free disc replacement, dramatically reducing setup time between process stages. The system includes a cooling water pipe with adjustable directional control, and an electromagnetic water valve enables convenient on/off control directly through the touch screen interface. This water cooling system effectively cools specimens during grinding and polishing, preventing thermal damage to the metallographic structure and ensuring the integrity of sample quality.
The iPoli-D Series: Compact and Versatile
For laboratories seeking a more compact solution, the iPoli-D series offers exceptional value without compromising performance. These manual metallographic grinding and polishing machines feature polishing discs with a standard diameter of 203mm (with customization options up to 250mm available). The series includes both single-disc (iPoli-1D) and dual-disc (iPoli-2D) models, with the dual-disc configuration allowing different processes or different samples to be handled simultaneously, significantly improving workflow efficiency. The machines incorporate stepless speed control from 50 to 1000 r/min, along with four constant speed settings at 150, 300, 600, and 800 rpm, providing flexibility for various materials and process requirements.
User-Centric Design Features
Both the MPoli and iPoli series are designed with the operator in mind. The iPoli-D includes an external aluminum pressure ring that secures polishing cloth without the need for pressure-sensitive adhesive, simplifying consumable replacement. A movable spray pipe allows precise control of water flow through a panel-mounted knob, while a plastic molded water shield effectively prevents splashing during operation. The structure is reasonably designed for easy daily maintenance and upkeep.
Wide-Ranging Applications Across Industries
These metallographic specimen grinding polishing machines find extensive application across numerous industries. In metallurgical analysis, they are used for preparing specimens of steel, aluminum alloys, copper alloys, and other metal materials. In semiconductor manufacturing, they are applied in wafer grinding and polishing processes to enhance chip performance and reliability. The machines are also essential for preparing rock and mineral specimens to observe internal structures and mineral composition, and for surface treatment of automotive components to improve wear resistance and durability. Additionally, they serve as valuable tools for teaching demonstrations and scientific research.
Comprehensive Consumables and Accessories
Mikrosize provides a complete ecosystem of consumables to complement its grinding and polishing machines. The standard delivery includes self-adhesive abrasive papers and polishing cloths, with optional accessories such as magnetic discs, non-stick discs, and a full range of diamond suspensions (both monocrystalline and polycrystalline), diamond polishing pastes, and polishing lubricants. Users can select from a variety of polishing cloth materials including velvet, flocked, canvas, silk, woolen, and nylon, each suited to specific material types and polishing stages. This comprehensive offering ensures that laboratories can achieve optimal results across virtually any material and application.
