Rotary Vane Vacuum Pump for CNC Machines: Solutions and Steps to Ensure Efficiency

When Does The Problem Occur?

The issue with the Rotary vane vacuum pump in CNC (Computer Numerical Control) machines typically occurs when there are operational inefficiencies, such as insufficient vacuum pressure or mechanical wear and tear. This can be due to improper maintenance, lack of lubrication, or aging parts.

What are the Solutions?

Having problems with your Rotary vane vacuum pump doesn’t mean the end of its lifespan. Here are several solutions:

Maintenance and Regular Check-ups

Regular maintenance and check-ups are crucial in preventing serious problems. Lubricating the pump and replacing worn-out parts can significantly improve its performance.

Proper Use and Operation

Ensure that the pump is operated at the recommended settings. Overworking the pump can lead to faster wear and tear.


Sometimes, the most cost-effective solution is to replace the old pump with a new one, especially if the current pump is frequently breaking down.

Steps to Resolve the Issue
