Machined PTFE at Pfaudler, Manufacture of an Earth Strap

Manufacture of a Carbon filled PTFE Earth Strap.

This clip demonstrates the use of multiple vices to hold a solid rod & in 2 operations how the material is machined to a thickness of 6mm & the job is completed.

1. (Auto Probe) illustrates how the Auto-Probe can be used to measure the exact centre of the material prior to machining.

2. (Face Mill) 63mm Shell Mill is loaded into the spindle, specifically chosen for its ability to remove large surface area cuts & leave impressive surface finishes.

3. (Mill Profile) 10mm End Mill is loaded into the spindle. The tool follows a path created using the CAM software and 3d model geometrical data.

4. (Circular Pocket) 10mm End Mill is then re-positioned to machine a circular pocket. The motion performed to complete this is described as ‘Circular Interpolation’.

5. (Face Mill) 63mm Shell Mill is loaded into the spindle. The material is machined down in incremental steps to the required depth (3mm above centre line)

The semi machined component is then rotated in the vice ready to proceed with the final operation.
The final operation consists of similar cycles as above.
