Core Technologies
1.Ultra-precision Machine Tool
Ultra-precision machining refers to machining at sub-micron level (dimensional error: 0.3-0.03 μm; surface roughness: Ra 0.03-0.005 μm) and nanometer level (precision error: 0.03 μm; surface roughness below Ra 0.005 μm). The process methods and technical measures adopted to achieve such machining are defined as ultra-precision machining technology.
Functions: It integrates ultra-precision turning, milling and grinding capabilities. It can turn outer circles, end faces, curved surfaces and micro-structures on end faces; perform grinding on outer circles, inner holes, end faces and curved surfaces; and realize CNC milling.
Machining Work-pieces: Suitable for ultra-smooth surface machining of ceramics, graphite and mono-crystalline silicon.
Equipment Applications: Used to investigate ultra-precision cutting mechanisms, tool wear and process optimization for aerospace hard-to-machine materials, as well as the effect of high-speed precision machining on fatigue damage of components.
2. Gear Measuring Center
It measures accuracy and other indicators of large and medium-sized gears. The probe automatically switches measurement directions with no manual intervention. A specially-designed probe protection mechanism provides 3D anti-collision capability. Adopting a host-slave computer architecture, the instrument achieves enhanced reliability. Four-axis simultaneous closed-loop trajectory control guarantees authentic measurement results. The ergonomically-designed mainframe enables easy workpiece loading and unloading. User-friendly human-machine interface software allows operation without specialized training.
3. Biological 3Dprinting Equipment
SIABioprinter-lab: Equipped with heating control for the printing platform and sterile processing. It automatically completes nozzle tool-setting, de-fouling and cleaning. Compatible with standard culture plates and standard syringes, it achieves a cell printing survival rate of over 90%.
SIABioprinter-pro: Features high-precision positioning and ultra-fine filament extrusion for micro-assembly of tissues and organs. It supports composite printing and concentration-gradient printing of hydro-gels and synthetic polymers. It is equipped with advanced, user-friendly biological 3Dprinting software algorithms, alongside automatic nozzle feeding, cleaning and sterilization systems.
