Hard Drive Data Loss & Data Corruption

Some of the earlier Siemens 810D and 840D controls can suffer from hard-drive data loss and corruption. This is more often than not caused by not shutting them down correctly. If the control is accessing or writing data to the hard-drive and it’s turned off, the files become corrupt, rendering your machine useless.

We were called to a Hardinge VMC600II with a similar issue. We resolved it by removing the hard-drive, copying a ghost image of the machine into the images folder in the temp partition and then booting into the service menus and carrying out an emergency windows partition restore.

Once the machine was booting correctly, new NC & PLC archives were made and then a complete ghost image of the hard drive was made.

We keep a large range of CNC machine tool spares and genuine parts in stock for your machines and if we don’t have it, we can find it!

Please contact us using the green button at the top of this page. We can help you book a service, quote you for a repair, or help you purchase the best quality parts for your business.

Spindle Drive Belt Failure

Spindle drive belts are often overlooked as part of routine PM checks.

This Hurco VMX42 suffered drive belt failure purely due to contaminant ingress on the belts, something that could have been avoided.

A noisy spindle and poor surface finish on his Hardinge lathe were the complaints from this customer. We carried out a site visit to diagnose, after a few checks and tests we concluded that the spindle bearings had started to fail.

Unfortunately, through excessive working, the grease had dried out. It was only a matter of time until the spindle seized completely, potentially causing more damage.
