Internal grinder UFB-500: surface finish of parts restored without teardown
Surface roughness of ground rings decreased, the machine regained its former surface finish quality. 20–26 % — micro-roughness of the ground surface, 1.5–1.9 → 1.2–1.4 µm (2001).

Key result
| EQUIPMENT | CONDITION AT START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| UFB-500 internal grinding machine (Yugoslavia) | Built in 1980, twenty-first year in service at the plant | Micro-roughness of the internal surface of test rings |
Finish of the ground surface of the test rings
| CONDITION OF THE HEAD | SURFACE MICRO-ROUGHNESS OF THE RING | CHANGE |
|---|---|---|
| Before treatment (baseline machine) | 1.5 ÷ 1.9 µm | — |
| After treatment with the XADO compound | 1.2 ÷ 1.4 µm | lower by 20–26 % |
Rings d 50 / D 70 / l 50 mm, 38KhA steel, HRC 42...46; ground on one and the same machine at 8500 rpm before and after the treatment.
