Together with our customers we design the complete grinding process. In addition to the machine, this includes the supply and removal of the parts to be ground as well as the optimisation of the grinding process by selecting the right grinding wheels and coolant. On request, an automated measurement of the ground parts with evaluation and NOK shunt can also be offered.
Blumberg has built high-quality grinding machines for a wide range of products for decades. GIA takes over Blumberg in year 2010 and continues this tradition with the development of new grinding machines and grinding concepts. Our product range includes double disc grinding machines and special customized grinding machines.

Grinding Gap Measuring Device SMP3
The further developed SPM 3 is a high-precision grinding gap measuring device. A wide range of accessories offers a multitude of measuring possibilities. The measuring device can be used in any double disc grinding machine to measure the grinding wheel geometry:
- Evaluation of the geometry of the grinding wheels in relation to each other
- Evaluation of the resulting geometry during grinding
- Evaluation of the resulting geometry after dressing
- Targeted adjustment of the tilting to optimise the grinding result
- Transfer and adjustment of an optimal grinding channel to other double disc grinding machines
- Evaluation of machine stability
- Mechanical troubleshooting
- Control of the printed circuit boards in the inlet and outlet area (option)
The SPM 3 is delivered with accessories in a sturdy aluminium case padded with foam inserts.
