1. Product Overview
Cutting is the first critical step in material testing and metallographic analysis. Irregular workpieces, non-standard castings, and complex automotive components have long suffered from industry pain points such as difficult positioning, single-mode cutting, specimen burning, and insufficient precision in thin-section sampling. Drawing on deep expertise in metallographic sample preparation equipment, Shanghai Yanrun has launched the ZQ-300F floor-standing, all-in-one three-axis (X/Y/Z) automatic intelligent metallographic cutting machine, custom-developed for non-standard and irregular workpieces. It covers diverse preparation needs—segmenting, depth-controlled grooving, ultra-thin sectioning, and multi-face precision cutting—in one machine, making it core precision equipment for sampling complex workpieces in automotive manufacturing, casting, material inspection, and research laboratories.
Traditional single-axis metallographic cutting machines can only perform simple vertical cuts. Facing complex workpieces such as gears, valve bodies, die-cast housings, and irregular forgings, they cannot achieve layered, horizontal, or linked multi-dimensional precision cutting, resulting in low sampling efficiency and severe cut deformation. The ZQ-300F is equipped with a three-axis fully automatic servo linkage control system and five switchable cutting modes, supporting both fully automatic batch operation and manual fine adjustment. It perfectly solves precision positioning and cutting challenges for all kinds of special workpieces, greatly improves the qualification rate of metallographic specimens, and reduces rework costs in subsequent grinding and polishing.
2. Core Design Advantages: Three-Axis Intelligent Architecture for All Types of Irregular Workpieces
2.1 X/Y/Z Three-Axis Fully Automatic Linkage with Micron-Level Positioning
The machine adopts an industrial-grade three-axis servo drive structure: automatic X-axis feed, Y-axis table displacement, and Z-axis vertical lift, each independently controllable and capable of linked operation. Travel parameters of all three axes can be customized via the touch screen, with stable and reliable positioning accuracy. For concave-convex irregular parts, long and short shaft castings, and multi-step automotive components, cutting height, feed distance, and lateral offset can be freely adjusted without repeatedly disassembling fixtures. Multi-position sampling of complex workpieces is completed in a single clamping, completely solving positioning deviation and sample size control problems for irregular workpieces.
2.2 Five Combined Cutting Modes Covering All Preparation Conditions
The machine carries diversified cutting programs with one-touch switching among five operating modes, adapting to different materials and sampling processes:
- Vertical cutting: standard cut-off and cross-section sampling for shafts and standard castings;
- Layered cutting: depth-controlled multi-layer slicing for precise ultra-thin sections, meeting gradient microstructure analysis;
- Horizontal cutting: lateral grooving and planar sectioning for sampling internal cavities of housings and gears;
- Three-axis linked cutting: synchronized multi-axis motion for contour-following precision cutting of complex curved surfaces and irregular profiles;
- Manual cutting: handwheel fine feed for precise supplementary cutting of small batches and special points.
Without changing equipment or modifying fixtures, one machine completes all laboratory cutting processes, greatly improving equipment versatility and reducing investment in multiple machine types.
2.3 Floor-Standing Heavy-Duty Body with an Oversized Pass-Through Cutting Chamber
The integrated floor-standing cast-steel base delivers high rigidity and low cutting vibration, with no accuracy decay over long-term operation. The left-right pass-through oversized cutting chamber features a side-sliding safety door, a panoramic explosion-proof transparent observation window, and built-in high-brightness LED lighting. Extra-long shafts, large valve bodies, and other long workpieces can be placed through the chamber without segmented cutting. The fully enclosed protective cavity with safety interlock automatically stops the machine if the door is not closed during cutting, eliminating abrasive wheel splash risks while ensuring both visibility and safe production.
2.4 Intelligent Electronic Control with Minimalist Touch-Screen Operation
Equipped with an 8-inch color industrial touch screen and a PLC intelligent control system, the fully visualized Chinese interface displays three-axis coordinates in real time. Cutting speed, feed rate, cutting depth, and cooling duration are all visually adjustable. The spindle offers stepless speed regulation from 100 to 3000 r/min, adapting to materials of different hardness such as soft aluminum, cast steel, cemented carbide, and heat-treated quenched parts. It automatically recognizes cutting load and slows down on hard materials, avoiding wheel damage and specimen burning, fully preserving the original metallographic structure and ensuring authentic, valid test data.
2.5 Efficient Circulating Cooling Plus Optional Magnetic Slag Removal
Multi-pipe universal cooling nozzles wrap the cutting zone from multiple angles, and a large-capacity circulating tank continuously delivers cutting fluid to quickly remove frictional heat, preventing metallographic phase transformation and surface burning. An optional magnetic metal impurity separator automatically captures metal debris in the coolant, extending the service life of cutting fluid and abrasive wheels, reducing manual cleaning frequency, and lowering consumable maintenance costs.
