High-Flyer with Uncompromising Precision

Röders GmbH uses the high-end measuring machine ZEISS XENOS for maximum accuracy in mechanical engineering

The company Röders GmbH in Soltau, Lower Saxony, produces high-precision milling and grinding machines. Tolerances are sometimes so tight that customers repeatedly wondered whether the measured values were precise enough. To dispel such doubts, the company has been relying on the most accurate measuring device in its size class: ZEISS XENOS. Since then, all of these discussions have come to a halt.

High-end coordinate measuring machine in bridge design

“Reliable and precise on every workpiece” – this is the value proposition that Röders GmbH presents to its customers. High-speed milling is the largest business area of the family-owned company which was founded over 200 years ago and manufactures approximately 150 machines per year. These machines are used for production processes in medical and dental technology as well as for automotive design studies and prototypes, and in the packaging and watchmaking industry. The company's main focus, however, is on tool and mold making, especially in injection mold making. It is here that precision is of paramount importance throughout the entire production process: ever-tightening tolerance requirements for tools and molds are now sometimes in or even below the micrometer range. This is a challenge for measuring technology.

The benchmark for tolerances in the submicrometer range 
Since high-speed milling always requires the utmost precision, Röders GmbH has been relying on ZEISS measuring technology now for more than 40 years. The company had already purchased the ZEISS PRISMO ultra coordinate measuring machine at an early stage and uses it to inspect large quantities of parts, especially during incoming goods inspections.

Röders GmbH has complemented its equipment with the ZEISS XENOS high-end gantry measuring device in order to inspect blanks, tools and parts with particularly high accuracy requirements. ZEISS XENOS is one of the most precise measuring machines in the world, even for larger workpieces.

Its unbeatable accuracy in the submicrometer range gives all parties involved the certainty that Röders machines deliver precision as promised. "ZEISS XENOS is simply the benchmark when it comes to part inspections in the submicrometer range within a measuring volume of nearly one cubic meter," says Managing Director Jürgen Röders. The machine delivers exact, reliable results after just one measurement run – thus saving time and money. After all, the more accurate the workmanship, the longer the useful life of a part. And the more precise a measuring machine, the wider the available tolerance range on the shop floor.

Accurate measuring results are often the main reason for purchasing a machine 
The measurement protocol generated by the coordinate measuring machine confirms that the machines meet the required tolerances – an important factor for a customer's purchase decision. "With ZEISS XENOS, we can convince our customers more than ever before that our machines excel at precision. This has a direct impact on our business success,” says Managing Director Jürgen Röders. 

High Performing ZEISS PRISMO family 

ZEISS PRISMO family is a reference in precision measurement – the best in their class are ZEISS PRISMO verity (accuracy of 0.7+L/400 µm) and ZEISS PRISMO ultra (accuracy of 0.5+L/500 µm). 

For measuring shaft-like parts, e.g., worm shafts, gears and rotors, the systems of the ZEISS PRISMO family are now available with the tailstock ZEISS TS. As a supplement to the rotary table, this allows shaft-like components to be clamped and measured between centers in a deformation-free and stable manner. The advantage: Clamping, measurement, inspection and evaluation all run on one machine.   

ZEISS PRISMO ultra becomes a form tester and coordinate measuring system in combination with the RT-AB air-bearing rotary table. This enables the system to measure form tolerances (such as roundness and cylindrical form) with high capability – comparable to specific high-precision form testers. Advantage: Both measuring tasks, dimensional accuracy and form accuracy, are performed on one machine in the same setup.
