High quality standards with the most modern technology

Assurance of the quality of all Kleemann plants has a high priority. The quality inspectors use the latest high-tech methods to do this.

It looks a bit like science fiction: Heiko Elischer, in charge of quality assurance at Kleemann, runs a device at some distance along the body of the plant chassis. Blue lasers flash in a stroboscopic rhythm; the device resembles an oversized atomic model. “This is quality assurance on the next level”, explains the quality technician enthusiastically.

The optical scanner he holds in his hands allows highly precise measurements to be made on all types of components. The size, material, surface quality and complexity of the parts to be tested are irrelevant. The scanner creates a one hundred percent image of the geometry of a component. This actual image is then compared by means of special software with the CAD design data, i.e. with the planned target state. Any deviations that exist are shown by colour differences. A huge advantage: The easily manageable device can be used directly in the production environment.

Emphasis is on quality

Kleemann continuously invests in the latest testing and measuring techniques. This ensures that the mobile crushing and screening plants comply with the highest quality standards when delivered. Suppliers are also scrutinized time and again.

The new scanner not only guarantees the quality. The advanced technology also provides new approaches in development and production. The measurement results, for example, enable faster entry into series production and the error rate in assembly is minimised.

Supplier samples can be measured in the micrometre range before production begins - this ensures that the final product corresponds exactly to the drawing template. Nasty surprises and production delays are therefore practically impossible.

Use of augmented reality

Another measuring instrument of the latest generation also involves comparing the target and actual status. However, the method used is different: The software uses augmented reality (AR). This technique, referred to as “augmented reality,” adds data to the existing environment. In this case, the CAD model of a component is precisely and reliably transferred virtually onto the test object. This allows the planned target state of the CAD drawing to be compared with the actual state of the manufactured component. Deviations are immediately visible.

The Kleemann quality technicians tested the AR software during a 6-month test phase and have now integrated it in the daily work routine. The revision check of the new MOBIREX MR 100 NEO was carried out completely with the new technique.

The objective: Plants of the highest standard

The two test instruments facilitate quality assurance in many areas: During production and assembly, easy and reliable checks as to whether everything is in the right place and correctly aligned are possible. Revision statuses can be compared; repair statuses can be determined. Costly downtime and rework in production can be avoided. The interplay between quality assurance and technology is being further optimised.

Co-operation with suppliers is also simplified as initial samples and incoming goods can be checked easily. It is also conceivable in future that components can be checked directly at the suppliers. If errors are detected at this stage, this results in lower transport costs and fewer disruptions to the overall process.

The new technologies have a wide variety of advantages. The bottom line, however, is that they primarily benefit the quality of the crushing and screening plants. This means that customers can count on every plant meeting the usual high Kleemann standards.
