Oil and dirt can cause contamination

Many people underestimate the damage that airborne oil and dirt contamination can do. Pictured below is the root cause of the failure of a Siemens 16/21 kW E/R module.

The internal fan had blown contaminants all over the board, eventually shorting and burning out several components and the track. Result: A complete replacement is required.

This could have been prevented by basic servicing and housekeeping, i.e., keeping fan filters clean, keeping electrical cabinet doors airtight, and keeping cabinets clean.

Control CNC Services can offer a full preventive maintenance service, which would help prevent such occurrences. Contact us for more details using the red button at the top of the page!

We were asked to build a Sinamics rig for a local repair company to enable them to demonstrate and function test the latest range of Sinamics drives, motors and hardware.

This rig utilises the latest Siemens Sinamics drive cliq hardware and works the same way as a CNC machine with 840DSL control.

CNC Machines are sensitive things often costing several hundred thousand pounds. In order to maximise their lifespan it is important to carry out regular housekeeping and checks.

When this machine was turned back on after Easter, carbon dust had settled on the drives and caused tracking on the main board of the E/R module which resulted in a large bang.
