IE A027TECHNICAL REPORT OF THE PERM MOTOR PLANT
RT-2000 CNC lathe: noise and seizing eliminated, spindle bearing not replaced
Spindle runout dropped by the end of the shift, knocking and jamming stopped, the machine was returned to the shop. 4× — spindle bearing runout at the end of the work shift, 0.06 → 0.015 mm (2012).
of the Perm Motor Plant
Key result
| EQUIPMENT | CONDITION AT THE START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| RT-2000 “Volenberg” CNC lathe, in service since 1992 | Knocking and cases of seizing in the spindle bearing; over a shift the runout grows from 0.01 to 0.06 mm | Spindle bearing runout; noise at idle and under load |
RT-2000 spindle bearing — before and after treatment
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Spindle bearing runout, end of work shift | 0.06 mm | not more than 0.015 mm |
| Bearing noise at idle and under load | Knocking | Eliminated |
Before the treatment the runout grew during the shift from 0.01 to 0.06 mm; the noise was assessed by ear.
