I. Usage

VMU Series is the most advanced CNC type video measuring system with 2 μm precision developed by Yihui.

It has been widely applied in machinery, electronics, mould, etc. for precision auto measurement.

Designed for rapid precision measurement & batch test in machinery, electronics, mould, etc

1. To measure point, line, circle, arc and oval, rectangular and improve the accuracy with the multi-point positioning function with clear observation.

2.Coordinate measurement, translation and coordinates straighten out.

3.Make measurement data directly into AutoCAD drafting and universal 3D Model file for professional design software like Solidwork, UG & Pro-E.

4.Record user program, editing and execute command.

5.In metrology terms, the machine can test width, length, height, thickness, straightness,flatness,

perpendicularity, circular degree, coaxiality, etc.

6.For example, the machine can test products as below:

1)Machinery: sheet metal, mould & die, gear, turning parts like bearings, shaft.

2)Electronics: phone& tablet sheet, PCB, watch parts, etc.

3)Plastics: mobile phone camera plate, cover, front bezel, slide plate, etc.

II. Features

1.It adopts TEO™ 1 /2'' color CCD camera and professional Pomeas™

auto zoom lens, big FOV, guarantee clear image during fast moving image measurement.

2.Grade 00 JINANQING granite base, goose-neck column, high stability structure. With German & Japanese auto-control technology, can achieve high precision motion.

3.Programmable control of integrated 40 group, 8 regional independent light sources, achieve professional surface measurement. Swift batch measurement help to cut labor cost.

4.Coupled with U.S. 2D+3D optical metrology software RationalVue™, wonderful measurement experience.

5.Option Renishaw™ touch probe & Keyence™ laser sensor available, high accuracy composite contact or non-contact 3D measurement available.
