Supfina adds the Spiro F5 and Spiro F12 to its line of fine-grinding machines for batch processing of a wide range of parts. The machines are designed to achieve precise plane parallelism (≤1.0 micron) for precision bearings, pump gears and valve plates in a variety of materials. Parts can be machined up to 20 times faster than lapping and with more precision than double-disc grinding, according to the company.
The smaller F5 can process parts with diameters ranging from 4 to 150 mm and thicknesses ranging from 0.3 to 50 mm, while the larger F12 can accommodate parts with diameters ranging from 6 to 420 mm and thicknesses ranging from 1 to 100 mm.
The machines eliminate water from the cooling process, reducing chance of contamination. The sturdy base minimizes vibration, reducing tool wear. The upper wheel swings away from the work area, enabling fast loading and unloading of parts, quick tooling changes, and easy maintenance.
