Stop Worrying About Large-Part Inspection! SINOWON's Full Range of Large-Travel Vision Measuring Machines Has You Covered

In manufacturing sectors such as new energy vehicle battery trays, liquid cooling plates, aerospace skins, large precision stamping dies, and PCB panels, workpiece dimensions are increasingly pushing toward larger and more precise specifications. However, the larger the workpiece, the more difficult the inspection. Traditional measurement tools often fall short when faced with large workpieces spanning several meters. Segmented measurement is inefficient and prone to missing critical deformation areas.

SINOWON has been deeply engaged in the precision inspection field for many years, offering a full series of large-travel Vision Measuring Machines covering high-precision standard versions, medium-sized production-line models, and ultra-large-travel configurations. Whether it is high-precision sampling inspection of small workpieces with large travel, routine production-line measurement of standard workpieces, or full-area measurement of ultra-large workpieces – from small travel to multi-meter ultra-large travel, from 2.5D optical measurement to 3D composite multi-sensor measurement – SINOWON provides a one-stop solution to help manufacturers achieve full-dimensional quality control of large-scale components.

I. What Can SINOWON Large-Travel Vision Measuring Machines Measure?

SINOWON large-travel Vision Measuring Machines are comprehensive Optical Measurement Machine (OMM) platforms for optical dimensional measurement and Geometric Dimension Measurement. Powered by high-resolution industrial cameras, high-precision optical lenses, and intelligent image processing algorithms, these systems enable non-contact, high-precision, multi-dimensional measurement of large workpieces.

• Flatness and Coplanarity Measurement

Large sheet metal parts are prone to warping after welding, stamping, or machining. SINOWON large-travel Vision Measuring Machines perform full-area scanning, automatically collecting Z-axis height data from hundreds of points to generate a colour 3D flatness cloud map – raised areas and recessed areas are immediately visible, with data quantified to the micron level, providing precise guidance for subsequent leveling processes.

• Profile and External Dimension Measurement

Whether it is profile inspection of irregular edges or external contour length and width measurement of large workpieces, the system automatically traverses and measures to quickly determine whether blanking dimensions meet standards. For applications such as PCB panel contour, liquid cooling plate flow channel profiles, and more, single-positioning, full-area measurement is achieved.

• Hole Position and Location Tolerance Measurement

For densely distributed cooling holes, mounting holes, and positioning holes on large workpieces, the software automatically identifies hole centres, precisely measures diameters and edge distances, and calculates multi-hole position tolerances – effectively avoiding assembly issues such as screws not aligning or misalignment. This capability is particularly critical for inspecting key parameters of liquid cooling plates, including flow channel width, flow channel spacing, and hole pattern dimensions.

• Thickness and Step Height Measurement

With optional laser or probe modules, the system precisely measures thickness uniformity of sheet metal and machined parts, as well as step heights of countersinks and embosses. Optional contact probes upgrade the system to a 3D contact measurement system; optional confocal white light sensors upgrade it to a laser-scanning measurement system.

• 2D and 3D Composite Measurement

SINOWON large-travel Vision Measuring Machines primarily perform 2D measurement while also offering 3D spatial dimension evaluation capabilities. From linear dimensions (length, width, height, diameter, distance) to geometric tolerances (flatness, perpendicularity, position tolerance, concentricity), the system delivers high-precision automated inspection.

II. What Problems Do SINOWON Large-Travel Vision Measuring Machines Solve?

1. Solving the "Can't Measure, Can't Measure Completely" Problem

Many inspection departments lack large-travel equipment, forcing them to perform segmented measurement or use tape measures on large workpieces – not only inefficient but also prone to missing critical deformation areas. SINOWON large-travel Vision Measuring Machines adopt a high-rigidity granite gantry moving structure or moving-bridge structure, with travel up to several thousand millimetres. The workpiece remains stationary during measurement, ensuring higher measurement accuracy and stability. Whether it is slender rail transit profiles or large-area sheet metal enclosures, PCB panels, or liquid cooling plates, single-positioning, full-area measurement is achieved.

• Solving the "Low Full-Inspection Efficiency" Problem

Manual sampling carries risks and is inefficient. SINOWON systems support CNC fully automatic programming for one-click measurement – once the program is set, even operators without measurement expertise can simply press start, and the system automatically traverses, auto-focuses, and automatically determines OK or NG. Fully automatic one-click full-profile measurement makes batch full-inspection of large workpieces a reality, dramatically improving inspection efficiency.

• Solving the "Data Traceability" Problem

With its supporting SPC software, every measurement data point is automatically archived. Managers can access historical records at any time, analyse process capability, and provide data support for process improvement. Measurement results can automatically generate SPC statistical analysis reports, monitoring production line process capability in real time and providing early warning of batch quality risks.

• Solving the "Contact Measurement Deformation" Pain Point

Large thin-walled sheet metal parts and precision machined components are prone to deformation under probe contact, affecting data authenticity. SINOWON large-travel Vision Measuring Machines use non-contact optical dimensional measurement technology, employing high-definition CCD and intelligent edge detection algorithms to capture true edges without stressing the workpiece, ensuring objective and reproducible data.

III. Broadly Applicable Across Multiple Industries

SINOWON large-travel Vision Measuring Machines are widely used in machinery, electronics, moulds, injection moulding, hardware, rubber, precision stamping, connectors, mobile phones, home appliances, printed circuit boards (PCB), medical devices, watches, cutting tools, military, power, bridges, ships, aerospace, and many other industries. Particularly suited for:

• PCB panels: overall panel dimensions, hole position accuracy, circuit contour inspection
• Liquid cooling plates: flow channel width, flow channel spacing, flatness inspection
• Large machined components: position tolerance, profile tolerance, dimensional accuracy inspection
• New energy vehicle battery trays: overall flatness, hole pattern inspection
• Large sheet metal enclosures: full-dimension profile and geometric tolerance inspection

Large-travel vision measurement is not simply magnification – it is a comprehensive test of precision, efficiency, and stability. SINOWON's full-series large-travel Vision Measuring Machines, backed by solid metrological traceability (each system is calibrated by authoritative metrology institutes and comes with an accuracy report) and a complete product matrix, provide a one-stop solution for workpieces of different sizes and accuracy requirements.
