m&h Case Study ZSM Zertz + Scheid - Gummersbach

Measuring to generate orders!

Measuring and logging of workpieces, while still clamped on the machine, has enabled ZSM of Gummersbach to win new customers. They perform measuring, machining and logging of nose gear for the Airbus A320 using this technology.

ZSM Zertz + Scheid Maschinenbau-und Handels GmbH has evolved from an engineering company covering a wide range of activities into one cutting high demand special material workpieces. “I haven’t machined normal steel for a long time now,” says production manager Klaus Mands as he describes the current situation. Here they manufacture a variety of parts for defence and offshore technologies and practice mechanical engineering in the very broadest sense.

Located in a new building in a recently built industrial estate on the outskirts of Gummersbach, they run multi-axis machines in their turning and milling shop. Customers increasingly demand integrated quality assurance and logging of machining results, workpiece by workpiece. This is why ZSM decided to do more measuring on the machine. To achieve this they purchased m&h touch probes and 3D Form Inspect software. They often machine very expensive materials, which are very difficult to replace if scrapped, and this prompted them to speed up the purchase and implementation of the new technology. The ability of ensuring a proper manufacturing process, by measuring between machining operations and logging the results, also helped in securing orders that would otherwise have been placed elsewhere.

Measuring of free-form surfaces and inclined spatial geometries during pre-machining of the Airbus A320 nose gear proved its worth from the first day onwards. Initially the forged blank is clamped horizontally and the workpiece position is determined using the Best Fit module included in 3D Form Inspect software. In a second measuring operation, the values of additional contour points are confirmed and another Best...
