During the processing of Auto Parts, precision Axis bearings, motor rectifiers, and Electronics components, Geometric Tolerance such as Roundness, Waviness, and Coaxiality of the workpiece directly affects the use effect of the product. Common caliper Measurement error is large, conventional Testing EquipmentAccuracy is insufficient. Chongqing Wanvei Instruments Y9025D Roundness Tester can meet the micron-scale Testing needs of rotary workpieces, and its Testing Center can undertake Testing business externally, taking into account both equipment procurement and specimen submission.

When manufacturing enterprises build new Quality Inspection Laboratories, they often face problems such as unreasonable layout design, scattered equipment procurement channels, mismatch between the experimental bench and the instrument dimension, and cumbersome installation and debugging by multiple manufacturers. Contact planning and design, laboratory bench, various instrument suppliers, cycle length, communication cost Height, and prone to rework problems such as equipment placement interference and insufficient load bearing. nChongqing Wanvei Instruments Co., Ltd. launched the integrated Laboratory landing service, which covers the whole process of site survey, overall space planning, customized experimental workbench, supply of all categories of Testing Instruments, on-site installation calibration, operator training, and builds a compliance standardized Quality Inspection Laboratory from scratch.

In the Mold Manufacturing, Sheet Metal Processing, and Large Machinery Parts Processing industries, there have been many pain points in Medium and Large Dimension Workpiece Testing: The conventional Image Measuring Instrument has limited stroke, and the workpiece must be split Testing, which is prone to secondary errors; complex surfaces, deep holes, and special-shaped ProfileTestingAccuracy are insufficient; the equipment operation threshold Height is difficult for newcomers to get started. nChongqing Wanvei Instruments has been deeply involved in the Precision Testing industry for more than 20 years, and is a professional Laboratory Solution Integration Service Provider. Its WVSeries Gantry Fully Automatic Image Measuring Instrument takes High Precision, Height Speed, and Height Stability as its core advantages. It is specially developed for Medium and Large Testing scenarios, and supports 5-meter workpiece complete machine measurement, without splitting the workpiece, and comprehensively solves the large workpiece Testing problem.

Precision Manufacturing Industry Quality Inspection. Automated Image Measuring Instrument is expensive and does not meet the small batch and multi-category Testing needs of small and medium-sized factories. To this end, Chongqing Wanvei Instruments launched the VMSSeries manual 2D Image Measuring Instrument. With the core advantages of stable Accuracy, easy operation, and expandable upgrades, it has become the mainstream equipment of precision parts DimensionTesting. The following brings you the comprehensive parameters and functions of this equipment.
