Bystronic: Modular system solutions for automotive glass

The tailor-made production lines are consistently designed for the customer’s individual requirements and permit extremely high productivity and optimal system availability.

In the course of an In-house Show Bystronic presented the champ’compact, a modular production line with its integrated cutting, breaking and drilling of high-quality automotive glass. Numerous decision makers of European conglomerates of the automotive glass answered the invitation to the Bystronic headquarter in Bützberg (Switzerland) and were able to assure themselves of the capability of the system.

After the general, theoretical presentation in the morning, in the afternoon the presentation of the champ’compact among production conditions was center of the event. This presentation took place in the customer center in Herzogenbuchsee.

Standard setting solutions with high productivity

The high-capacity automotive glass processing line for windshields is made up of cutting- and breaking machine, grinding machine and integrated drilling machine.

The compact system concept was further developed and guarantees highest process precision and accuracy of part shape with maintaining short cycle times of approx. 18 – 25 seconds (depending on shape of the windshield). The process sequence is program controlled, avoiding mechanical positioning. The high degree of automation ensures short change-overs and an efficient usage of the system with a minimum need of operating personnel.

The newly developed drilling machine offers a high flexibility and covers a large process area. Several holes of different diameters can be drilled simultaneously. Pre-programmed macros ensure the convenient selection of various drilling sequences. Given the modular construction concept several drilling stations may be installed in series in order to perform complex drilling plans within the specified cycle time.

The standard equipment of this drill includes an automatic calibration system to determine the drill height, an automatic dressing device, as well as an efficient coolant evacuation.

New test system for grounded glass edges

The participants were notably impressed by the newly developed test system for grounded glass edges GQM (Glass Quality Measure). Registering, analyzing and visualizing of the chipping at the transition from glass surface to ground edge can be done with this system in a matter of seconds. Therefore a precise control of the edge quality e.g. during the grind in of a new grinding wheel or during the production is guaranteed.

Via a high dissolving video camera even the tiniest chippings are registered and with adequate pictures file saved in a database. Simple comparison of the edge quality due to predefined GQM quality numbers is possible and therefore a fast and easy control is ensured.

Besides the easy handling and the various analyzing possibilities the new test system convinces with its mobile application and offers the customer a valuable help due to its quality assurance.

In-house Show successful

After the event the invited visitors were visibly impressed by the productive efficiency of the system and with their judgment they made sure that the In-house Show could be assessed as a success. Therefore Bystronic wants to expand this In-house Show to a regular.
