Roll Surface Inspection System

The key to a successful surface analysis is the scanning angle to the surface of the web and the arrangement of the light source.

Roll surface inspection system.

Quality inspection overview rsis optical roll surface inspection system for roll grinders reduces down time of strip foil mills improves roll shop performance identifies and classifies finest surface finish patterns defects on ground rolls defect classes. Our high end wide fabric inspection systems are suitable for tenter frames blockers winders coating or laminating machines and other roll to roll applications. A surface analysis system is normally installed after a process for quality control. Work roll inspection work rolls have a very important role in the rolling process as they need to have a special finish roughness that will be applied onto the surface of the strip.

Eddy current and ultrasonic systems can either be used as stand alone devices or integrated in the machine control. Rollmate is the most advanced roll inspection system on the market. Chatter marks spirals shadows grit marks scratches indents etc. All herkules grinders are equipped with the herkulesgroup hcc kpm kp10 control and on line on the fly roll measuring gauge.

The system detects all kinds of deviations in the surface of the material combining very high image resolution with speeds up to 100 m min. Rollmate inspects rolls of any alloy forged and cast during or after the grinding process. Up until now it has been assumed that the fine structure has been finished after machining. Special image evaluation software detects and displays roll surface defects such as chatter marks and feed lines commas or combinations of these and defines their location.

After the inspection the operator immediately knows whether the roll is free of defects. The system also detects defects occuring only once. Depending on the particular task the web surface for surface inspection is detected using either incident light or transmitted light. In case a defect is found its size structure and position on the roll are indicated.

The roll surface inspection system registers and records the reflexion of a laser beam on the roll surface.
