What is a servo press?

A servo press uses servo motors for precise force and position control during forming operations.

Servo Press Lubrication System: Maintenance and Troubleshooting

admin

## Lubrication System Overview

Servo presses use centralized lubrication systems to deliver oil to gibs, crankshaft bearings, connecting rod bearings, and slide guides. Lubrication failure is the leading cause of premature wear on servo presses.

## Types of Lubrication Systems

**Centralized oil lubrication (most common):** A pump delivers oil through distribution blocks to all lubrication points. Oil is recirculated or total-loss depending on design.

**Grease lubrication:** Some smaller presses use grease nipples. Requires manual greasing every 500-1000 hours.

## Daily Checks

- Oil level in reservoir: should be above minimum mark
- Oil flow indicator: should pulse with each pump cycle
- No oil leaks at distribution blocks or tubing

## Common Faults

### Low Oil Level Alarm

Check reservoir level. If oil consumption has increased suddenly, check for leaks at all distribution points and tubing connections.

### No Flow at Lubrication Point

Cause: blocked distribution block or kinked tubing.

Fix: Remove distribution block, clean with solvent, blow out with compressed air. Check tubing for kinks.

### Pump Not Running

Check pump motor power and control signal. Most lubrication pumps are controlled by the press PLC — check PLC output for pump command.

## Oil Specification

Use the oil grade specified in the press manual. Typical: ISO VG 68 or VG 100 for gib lubrication, ISO VG 32 for high-speed bearing lubrication. Do not mix oil grades.

## Oil Change Interval

Change lubrication oil every 2000 operating hours or annually, whichever comes first. Take an oil sample before changing — metal particle analysis reveals bearing wear before failure.

The #1 lube system failure mode: clogged filter. Most centralized systems have a 10-micron filter that nobody changes. It clogs, pressure drops, and the far-end lubrication points starve. We change the filter every 3 months regardless of the pressure gauge reading. A $20 filter prevents $20,000 in bearing damage.

For shops in cold climates: lube system viscosity matters. If your shop drops below 10?C overnight, the grease in the lines can thicken enough to prevent flow at startup. Either use a lower-viscosity grease or install a line heater. We've seen gib scoring from dry starts on cold Monday mornings.
