EQUIPMENT	WHAT WAS TREATED	WHAT WAS MEASURED
Jones-Shipman cylindrical grinding machine, inv. No. Sh-170	Gearbox, in regular shop operation	Gearbox noise level before treatment and after operating time

Gearbox noise level over the course of observation

OBSERVATION STAGE	NOISE LEVEL
Before the work started	75 dB
After ≈40 h of operation (about a week) — grinder operator's assessment	Noticeable noise reduction by ear
After ≈110 h of operation — repeat measurement	63 dB

Measurements were taken at the gearbox before the product was added and again after ≈110 h of machine operation; the unit was not disassembled during this period.

Conclusion of the plant commission

The commission of JSC MZKRS recorded a reduction of the noise level in the gearbox of the cylindrical grinding machine from 75 dB to 63 dB. The grinder operator noticed a marked reduction by ear after just 40 h of operation; the instrument measurement was taken after 110 h. The unit was not opened and no parts were replaced: the revitalizant gel was added to the lubrication system of the machine, which stayed in shop operation. Conclusion of the report: "the positive results achieved demonstrate the effectiveness of using the revitalizant gel of the XADO company on metal-cutting equipment".

The results apply to the gearbox of the Jones-Shipman cylindrical grinding machine under the conditions of the machine shop at JSC MZKRS; on other equipment and under different operating modes the figures may differ. The original report with signatures and seal is published in full and available for download.
