About Blum-Novotest
Blum-Novotest GmbH is a family-owned manufacturer of innovative measurement and testing technology headquartered in Grünkraut (Baden-Württemberg) with a second site in Willich (North Rhine-Westphalia). The company develops and manufactures in three business divisions: BLUM measuring components for tool and workpiece measurement in CNC machine tools, BLUM measuring machines for dimensional, geometry and crack testing in series production, and NOVOTEST test stands for the automotive and hydraulics industries. The portfolio includes laser measuring systems, measuring probes, roughness measuring devices, bore gauging heads, measuring software, multi-station measuring machines, eddy current crack testing systems, as well as gearbox, drive shaft, hydraulics and E-drive test stands including custom systems. The systems are manufactured in Germany and supported worldwide by the company's own sales and service subsidiaries. Customers come from the machine tool, automotive and aerospace industries as well as from the energy, medical and mould-making sectors. The company has been in the market for over 50 years and employs more than 700 people worldwide.

Materials and Applications
Stainless steels
Material for tested precision components in series production, including quick-release couplings.
Heat-treatable steels
Used for components such as drive shafts and gearbox parts that are tested with BLUM metrology.
Free-machining steel
Material for turned parts produced in large series with tolerances down to 2 µm parallelism.
Aluminium
Lightweight material for workpieces measured with measuring probes in the machine tool.
Full ceramics (ceramic inserts)
Material for components that are difficult to clamp, whose machining is automatically monitored with measuring probes.
