Friction Surfacing Machines

Friction Surfacing is a process derived from friction welding, whereby a coating material, in rod form is rotated under pressure, generating a plasticised layer in the rod at the interface with the substrate. By moving a substrate across the face of the rotating rod a plasticised layer between 0.2-2.5mm thick is deposited, depending on rod diameter and coating material.

Machines can be built to cater to various axial loads and job sizes.

Machines can be supplied in single or double column configuration.

To maintain Spindle angle in linear Surfacing the head can be tilted manually.

For contour Surfacing the Spindle head can be tilted automatically to follow the required path.

Rotary table can be incorporated for cylindrical jobs.

The machine is controlled through a high-end CRIO module PLC from National Instruments with the software- Lab VIEW Real Time.

The following data is acquired and recorded:

• X- axis load / displacement • Y- axis load / displacement • Z- axis load / displacement • spindle speed / torque
