In metallographic analysis and materials research, the quality of sample preparation directly determines the accuracy of subsequent microscopic examination and mechanical testing. The uCut-60 Automatic High-Speed Metallographic Precision Cutter from Mikrosize is engineered to deliver consistent, deformation-free sectioning for a wide variety of materials—from metals and hard alloys to ceramics, composites, and even sensitive biomaterials. As a core instrument in modern metallographic sample preparation, this cutter combines intelligent automation with robust construction to meet the rigorous demands of industrial laboratories and research institutions.
Intelligent Automation for Reliable Cutting

  The uCut-60 features a fully automatic cutting cycle that eliminates guesswork and reduces operator intervention. The machine automatically detects when the sample has been completely cut through, then stops cutting and retracts the cutting wheel to its initial position—eliminating the need for manual stroke setting. This smart functionality not only prevents over-travel but also ensures consistent cutting depth across multiple samples.
Parameter management is simplified with the ability to store up to 99 sets of cutting programs. Operators can recall stored parameters for different materials without re-entering settings each time, significantly reducing setup time and minimising human error. The system supports different feed speeds and spindle speeds within a single cutting process, allowing optimisation for multi-material or layered specimens.
Precision Motion Control and Cutting Performance

At the heart of the uCut-60 is a servo motor-driven spindle with closed-loop control and overload protection, ensuring stable torque delivery across the entire speed range. The spindle speed is adjustable from 5 to 3000 rpm, providing the flexibility to select the optimal rotational speed for each material—lower speeds for hard, brittle materials and higher speeds for softer metals. The feed speed can be set from 0.01 to 3 mm/s in 0.01 mm increments, enabling precise control over the cutting rate to minimise thermal and mechanical damage.
The Y-axis cutting stroke measures 200 mm, and the machine accommodates cutting wheels of standard size φ200 × 32 × 0.9 mm, available in diamond, CBN, or resin bond types. Maximum cutting diameter is Φ60 mm, and the cutting table measures 216×240 mm, providing ample workspace for small to medium-sized specimens. The servo motor delivers 1.5 kW of power, ensuring sufficient cutting capability for even challenging workpieces.
Advanced Features for Versatile Applications

The uCut-60 offers two cutting modes—automatic and manual—to suit different operational preferences and sample geometries. An optional X-axis movement (uCut-60X model) provides automatic or manual parallel motion with precision of 0.01 mm over a 40 mm range, enabling multiple parallel cuts without repositioning the sample. This feature is particularly useful for producing uniform slices from bar or plate materials.
For models equipped with sample rotation (uCut-60R), the R-axis rotates the specimen during cutting, effectively reducing localised heating and allowing the user to cut the same sample from different positions. This rotational capability is invaluable for minimising thermal artefacts in heat-sensitive materials.
User-Friendly Interface and Operational Safety

The machine is controlled via a large 7-inch touch display with an intuitive man-machine interface powered by PLC (Programmable Logic Controller). The interface is ergonomically arranged and supports customisable languages for user-friendly operation. Real-time feedback on cutting parameters, spindle speed, and feed rate keeps the operator fully informed throughout the process.
Safety is paramount: the cutting chamber features a closed, transparent protective cover with a safety switch that immediately stops operation when opened. An automatic cleaning system utilises spiral nozzles within the cutting chamber, which can be activated manually or set to start automatically after each cut. This ensures a clear view during operation and simplifies post-cut maintenance. The external circulating water cooling system effectively dissipates heat, preventing thermal damage to both sample and cutting wheel. Additionally, a sample collection feature prevents small pieces from falling into the chamber, aiding in specimen recovery.
Application Scope and Ordering Options

The metallographic precision cutter is ideally suited for precision cutting of small components in metallurgy, electronics, ceramics, geology, and biomedical research. Its high spindle speed, thin cutting wheel, and precise positioning make it particularly effective for preparing specimens for microscopic analysis.
Ordering options include the standard uCut-60 model, the uCut-60X with X-axis movement, and the uCut-60R with sample rotation capability. Standard delivery includes the host machine, diamond cutting wheel, cooling system (water tank, pump, hoses), cutting fluid, tool kit, and external water tank.
Technical Specifications Summary

With its combination of intelligent automation, precise motion control, and robust safety features, the uCut-60 series stands as a premier solution for high-speed precision cutting in modern materials laboratories.
