CNC Video Measuring System
iNEXIV VMA 6555 with touch probeThe iNEXIV VMA series CNC video measuring system offers the ultimate in usability for automatic measuring of various 3D components with a large FOV, long working distance and wide XYZ stroke.
Suitable for large samples (450 x 400 x 200 mm or larger) and simultaneous measurement of multiple parts. High cost-performance with the same strong cast-iron body and direct bearing as the high end models. The VMA-6555V is for video measuring, while the VMA-6555 is touch-probe ready.
A wide FOV of up to 13 mm x 10 mm (at 0.35x) allows easy search and alignment of measuring targets. The 10x zoom with five specific steps provides accurate measurement as well as high resolution images. An excellent Apochromat objective lens with high NA (0.11) and low distortion has been specially designed for the iNEXIV series, providing crisp, clear images.
A long 73.5 mm working distance minimizes the possibility of contact between the objective lens and valuable parts. It is ideal for measuring large step heights, tall bosses and deep holes.
The XY stroke of the VMA-6555V/6555 is 650 x 550 mm and is suitable for measurement of large samples and simultaneous measurement of multiple parts. The extended 200 mm Z-axis stroke is ideal for tall workpieces.
Highly repeatable vision AF offers high-speed, high-precision focusing and height/depth measurement.
Even the bottom of a small diameter hole can be brought into correct focus.
The Laser AF with a long 63 mm working distanc
e is optionally available, enabling height measurement of flat surfaces with high repeatability, in keeping a wide FOV at a low magnification.
Episcopic (top), diascopic (bottom) and 8-segment-ring (with 18-degree oblique angle) LED illuminators enable accurate detection of low contrast edges.
Any 8-segment light can be selected for effective edge detection.
Even when a workpiece is misaligned, the system automatically searches the target location based on the target image recorded in a teaching file, enabling accurate, automatic measurement by eliminating possible detection errors.
Deviation of contours can be checked by overlaying charts generated digitally from 2D CAD data onto video images. Digital charts always accompany video images.
Touch probe for measurement of imperceptible parts from top and bevel angle
TP200
The VMA-6555 is touch-probe ready and accommodates optional Renishaw® TP20 or TP200 touch probes to measure 3D shapes parts where vision AF cannot be used. Touch probe and vision measuring are seamlessly switched, since the touch probe works coaxially as the optical axis using dedicated software.
Each model can be modified before shipment to extend magnification to 1.5x, powerful enough for precise measurement of minute electronic parts.
*Video measuring images are slightly darker than that of standard magnification.
