Regular Maintenance to Maximise your machine's lifespan

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.

We were called to this particular job after the Machine was shutdown over the Easter period, unfortunately when it was turned back on, 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 and a £10,000 module to self destruct.

After a thorough health check, replacement E/R module and 3 mains 200A fuses, we were able to get the machine running again.

Unfortunately as a result the NC had lost it's memory, we reloaded the most up to date backup was from July 2016 and the Setter/Operator had to spend time resetting the machine offsets and tool data.

All this was avoidable by simple housekeeping, a daily check and clean of the electrical cabinets would minimise risk of contamination and huge repair bills.

Many people underestimate the damage that airborne oil and dirt contamination can do. Pictured here is the root cause 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.

This customer based on the south coast had returned to their machine, an Emag VSC 400 Duo with Sinumerik 840D and 611D drives and suffered huge issues.

On returning power to the machine, a large bang was heard and machine power was lost resulting in an alarm 120202 waiting for connection to NC PLC with a flashing control panel.
