Most Carbide Damage Happens Off the Machine
Carbide is extremely hard but it does not tolerate point impact. A large proportion of damaged parts are damaged in transit in the store or during fitting rather than in service.
Handling and Storage
- Do not stack carbide parts directly against each other. Edges chip edges.
- Keep the original protective packing until the part goes to the machine.
- Never drop a carbide part onto a steel bench even from a short height.
- Store rings sleeves and discs flat and supported rather than resting on an edge.
Fitting
- Check the seat before fitting. A dirty or damaged seat loads the part unevenly.
- Use even pressure. Hammering a carbide part into a holder is the fastest way to crack it.
- Follow the interference fit that was agreed on the drawing.
- Do not correct a fit by grinding the carbide unless it was designed for it.
Inspection in Service
Record how long each part runs. A simple log turns replacement into planned maintenance and gives you real data if the wear life changes between batches.
If the wear life does change send photos of the worn part with the run time. That comparison is far more useful than a general complaint. See contact us.
