short description

Computerized 100% quality control, automotive grade

Feeding without requirement for part orientation, internal orientation station

Dimensional measurement of all outer dimensions and shapes

Dimensional measurement of the complete inner profile

Measurement of dynamic dimensions like eccentricity/run-out, roundness and straightness on outer and inner diameters

Complete optical surface error detection on outer and inner surfaces by enhanced image processing

Crack inspection on outer and inner surfaces

Throughput of more than 20 Valve Guide Inserts per minute

Change from one Valve Guide Insert type to another in less than five minutes

Enhanced self-control and diagnostic functions, automatic logging of errors

Image processing, user interface and machine control with one single computer

All data is stored on Memory-Cards with the possibility for network/server integration for easy updating and managing the system

Easy to use, graphical menu-based program with online help functions

Valve Guide Insert drawing, all signals, images and evaluation data are displayed in real time on the color monitor

Remote diagnistics and service capability over LAN, WAN and Internet

Control signals for feeding and packaging unit

Results Statistics with the possibility to optionally store a measurement protocol for each part (protocol requires external storage)

Self maintaining order library with used parameters, results statistics and parameter modifications log

All measurement parameters are computer controlled with a central storage and recall function
