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: Preventing the Most Common Failures

admin

Lubrication failures cause more servo press downtime than any other single factor. They are almost entirely preventable.

## Two Separate Systems

Centralized grease system: lubricates slide gibs, guide pins, die cushion components. Forced oil circulation system: lubricates main gear, eccentric bearings, connecting rod bearings.

## Centralized Grease System Failures

### Blocked Distribution Lines
The most common failure. Grease hardens in lines over time. Detection: check each point with a grease gun after the automatic cycle. Fix: blow out with compressed air. Prevention: use NLGI 1 or 2 grease as specified in the manual.

### Pump Timer Drift
Verify timer setting against the manual every 6 months.

### Low Grease Level
Check reservoir level weekly. Do not rely only on the low-level switch.

## Forced Oil System Failures

### Filter Clogging
Replace every 6 months or when differential pressure indicator shows red.

### Oil Cooler Fouling
Clean fins with compressed air every 3 months. Normal oil temperature: 40-60C. Above 70C investigate cooling.

### Oil Contamination
Milky appearance indicates a cooler leak. Change oil annually regardless of condition.

## Annual Lubrication Audit

Verify every lubrication point is receiving lubricant. Check all line connections for leaks. Verify pump output volume. Review oil analysis trends.

The distributor blocks are the weak point in centralized lube systems. Each outlet has a tiny piston that can stick if the grease is contaminated or too cold. I check each outlet monthly by disconnecting the line and cycling the pump —you should see grease come out of every port. If one is dry, the block needs cleaning or replacement.

Operator tip: the lube system low-level alarm is your friend, not an annoyance. I've seen guys tape over the warning light because it goes off too often. Then the system runs dry and you're looking at $15,000 in gib damage. Top off the reservoir every Monday morning. Takes 2 minutes.
