Exhibits

The MIT Taiwan-made image measuring system uses a precision-grade granite structure, Panasonic servo motors on the XYZ axes and ground-grade crossed-roller linear guides. For that platform, XY movement measurement accuracy is specified as ±0.003mm and measurement repeatability as ±0.001mm. An optical configuration with a 10x eyepiece provides total magnification from 50x to 1000x and a stated minimum resolution of 0.37um for observing microstructures in different materials. The optical system supports modular expansion and multiple observation methods, extending the equipment from dimensional measurement into microstructure inspection. Surface-analysis functions include 3D observation of microstructures, Z-axis 3D PROFILE measurement of fine structures, non-contact roughness measurement and surface-structure measurement for materials with different reflectivity and transparent materials. The stated Z-axis resolution for the white-light-interference surface work is 1nm to 0.1nm. JYS lists manual image measurement, semi-automatic measurement and fully automatic measurement as distinct operating configurations, with manual systems moving all XYZ axes manually, semi-automatic systems automating Z while XY remains manual, and fully automatic systems automating all three axes together with lighting and lens magnification. Its measurement software can perform geometry and geometric-tolerance measurement with functions such as automatic edge finding, multi-point sampling and mouse-point sampling for shape and contour measurement. The software portfolio also combines image measurement with touch probes and laser displacement sensors so that 2D coordinates, 3D geometric elements, flatness and height can be measured in one application environment. Report functions support multiple output formats and allow measurement content and report form to be configured for dimensional inspection records and quality analysis. A high-precision fully automatic optical measurement system adds intelligent program teaching for batch dimensional inspection and combines high efficiency with optical magnification up to 1000X. That high-precision system uses an Orientalmotor servo motor and THK precision-grade linear guides on the XY moving platform. It supports 3D measurement, photography and stitched-image processing so that dimensional inspection and microscopic image work can be combined on the same platform. A dual-lens fully automatic measuring system uses a wide-angle lens and a high-magnification lens, with the two lens magnifications stored in measurement templates for batch work. The dual-lens configuration uses a 20-megapixel high-resolution industrial camera and is intended to switch between large-field positioning and precise dimensional inspection. The large-travel fully automatic image measuring line covers measurement travel from 600mm to 1500mm and uses high-resolution digital imaging instead of conventional analog-camera resolution. Large-travel models listed include MVJ-0606L, MVJ-0810L and MVJ-0813H, with respective XY travels of 600×600mm, 800×1000mm and 800×1300mm. The large-travel system combines a high-resolution industrial camera, telecentric optics and multi-stage LED illumination with automatic edge recognition, focusing, edge finding and CAD drawing comparison. Optional modules include automatic zoom, a contact probe and a laser displacement sensor for 2D dimensions, 3D height, flatness, hole location and complex contours. Its inspection results can automatically determine OK or NG and export Excel, PDF and SPC statistical-analysis reports for quality tracking and process improvement. The listed MVJ large-travel equipment provides a 200mm Z-axis movement and an optical system using GigE high-speed color digital imaging with an 18X to 200X lens range and 11mm to 1.7mm field of view. JYS also supplies metallographic equipment covering cutting, embedding, grinding, polishing, microscopic observation and analysis software, forming a preparation-to-analysis workflow for material microstructures. Its fully automatic four-axis large cutting machine uses XYZR four-axis control, a wireless handwheel, an extra-large worktable and cutting chamber, plus a magnetic separator and paper-tape filtration system. A fully automatic PCB precision cutting machine uses a 5-inch touchscreen, manual or automatic programmable laser tool setting, rapid sample clamping and a concealed cooling system, with optional automatic clamping for irregular workpieces. The UV fast embedding machine can produce a transparent specimen in 60 seconds and uses a 4.3-inch touch interface with one-button operation and four preset embedding times. For quantitative grinding, the AL610 pneumatic automatic grinder is specified for grinding different materials and polishing surfaces with a grinding and milling precision setting of 0.01mm, a 7-inch touchscreen and an optional four-unit automatic dripping system. A single-disc manual grinding and polishing machine operates at a standard 50 to 600 RPM and can be set to a maximum of 1000 RPM, with a wide-angle drain design intended to prevent water accumulation and blockage. The metallographic workflow emphasizes selecting representative specimens and sufficient cooling during cutting so local heat does not alter the structure being examined. After grinding and polishing, an appropriately etched specimen can be observed with an optical microscope and photographed with a high-resolution camera for records or subsequent metallographic analysis. Metallographic analysis software covers common analyses such as grain size and grayscale metallography and uses algorithms to evaluate structures according to standards including ASTM, JIS, ISO and GB. Listed software analysis functions include spheroidization rate, decarburized layer, grain number, inclusions, tempered martensite and quenched-steel analysis, with report export for result images and data. The metallographic software can also analyze residual ferrite and decarburization depth and can output images and data in formats including BMP, JPG and Excel. Industrial microscope supply includes imported second-hand microscopes from brands such as NIKON, OLYMPUS, LEICA and ZEISS, with options for magnification, photography, measurement and analysis software. Those second-hand industrial microscopes can be configured with observation methods including dark field, PO polarization and DIC differential interference according to the inspection task. The microscope service is positioned for industrial inspection rather than only resale, with equipment selection and optical configurations matched to observation and measurement requirements. JYS describes inspection and maintenance support for used microscopes as part of the service, extending their use through configuration, measurement accessories and application assistance. The used-microscope offering therefore complements new optical systems by providing alternative platforms for materials observation, photography and quantitative measurement. Dimensional-measurement applications listed by JYS include metal-product machining, semiconductor wafers and other precision parts where size, position, geometric tolerance and coordinate information must be inspected. Its application coverage brings dimensional measurement together with metallographic analysis and 3D microscopy rather than treating those functions as unrelated product categories. For microscopic photography, a 4K imaging system can perform measurement and photography without a computer, while connection to a computer enables advanced functions such as EFI depth stacking and MIA image stitching. The listed 4K microscopy configuration uses a 16-megapixel large sensor for live imaging and image-processing work. These optical and 3D functions are applicable to materials such as metal, plastic, rubber, glass, PCB and ceramic in precision-manufacturing inspection. Hardness-testing equipment covers Rockwell, micro Vickers, Leeb and fully automatic micro-hardness systems for different material forms and testing requirements. The DHV1000 micro-hardness tester is designed in Taiwan and supports Vickers, Knoop and carburized-layer tests for hardness analysis of multi-component materials. The THV1000 touchscreen micro-hardness tester provides a smart touch LCD interface, automatic hardness calculation and immediate display of complete test information. The KH260 handheld Leeb tester uses a one-piece design, a Traditional Chinese interface and multi-point average statistical analysis, while the TIME Leeb tester displays multiple hardness values and is intended for portable testing of metal materials. The hardness line is described for semiconductor, electronics, automotive, aerospace, metal processing, heat treatment, mold, tool, medical-device, energy and railway applications. The hardness systems reference ISO, ASTM and JIS testing standards and combine load control, precision indenters, optical measurement and intelligent software functions such as automatic focusing, data analysis and hardness conversion. Across its catalogue, JYS combines image measurement, microscopy, metallography, 3D surface metrology and hardness testing with customized integration so an inspection system can be configured around the part, material and required measurement method.
