In metallographic analysis, material testing, and quality assurance, the preparation of high-quality specimens begins with precise, damage-free cutting. The Mikrosize AutoCut-250 is a 3-axis automatic intelligent metallographic cutting machine designed to meet the most demanding sampling requirements across a wide spectrum of industries. Combining robust construction, intelligent feeding control, and versatile cutting modes, this equipment delivers consistent, reproducible results for laboratories, production floors, and research institutions.
Intelligent Feeding and Multiple Cutting Modes
The AutoCut-250 features a high-torque servo motor with a continuously variable speed system (500–3000 rpm), providing strong power and high efficiency for cutting a variety of materials. Its intelligent feeding system automatically monitors cutting force—reducing feed speed upon encountering resistance and resuming the preset speed once the obstacle is cleared. This adaptive control minimizes the risk of wheel breakage and thermal damage to the specimen.
Offering a high-quality multiple combination cutting mode design, the machine supports five cutting methods: vertical, layered, horizontal, linear (pulse), and manual cutting. This flexibility makes it ideal for precision positioning cutting and sampling of irregular and non-standard parts, including automotive components, castings, and specialty alloys. The X-axis can be configured as automatic or manual (depending on the model), while Y-and Z-axes feature automatic feeding as standard, enabling full-programmed operation.
Technical Excellence and Robust Construction
Equipped with a 250 × 32 × 1.5 mm aluminum oxide resin cut-off wheel, the AutoCut-250 achieves a maximum cutting diameter of 90.5 mm. The spindle speed range of 500–3000 rpm accommodates both soft and hard materials. The machine is built with an electrostatic-sprayed, high-strength cast aluminum alloy base, ensuring stability, rust resistance, and durability. The cutting chamber is made of high-strength integrally molded composite material, resistant to rust and easy to clean. The worktable, constructed from 304 stainless steel with T-slots, is corrosion-resistant and allows for quick clamp changes. A standard quick-release clamp (304 stainless steel) simplifies operation, while optional vertical clamps or other fixtures expand application versatility.
User-Centric Design and Safety Features
The AutoCut-250 incorporates an 8-inch high-definition color touchscreen combined with physical control buttons, offering intuitive operation and real-time parameter monitoring. A large transparent window provides clear visibility of the cutting chamber, while built-in high-brightness LED illumination facilitates observation of the sample condition during the process. The machine includes an electronic brake for rapid wheel stopping, and low-voltage control components (Schneider Electric) ensure safe and reliable operation.
A standard high-pressure flushing system—including an independent spray gun—simplifies cleaning of the cutting chamber after use, extending equipment service life. The removable plastic recirculating water tank (70L capacity) provides efficient cooling, with an optional high-intensity magnetic filtration water tank available for enhanced particle removal. An optional laser positioning function further improves cutting accuracy by projecting a visible alignment line onto the workpiece.
