Bronze filling delivers the highest compressive strength and thermal conductivity for high-load, high-speed duty.
Bronze-Filled PTFE is a Bronze-Filled grade within PTFE (Teflon), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.
Bronze filling delivers the highest compressive strength and thermal conductivity, suitable for high-load, high-speed applications.
Bronze-Filled PTFE grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.
Bronze-Filled PTFE demonstrates the following core advantages in CNC machining and end-use applications.
The following are key process points when machining PTFE (Teflon) material, to ensure part quality and machining efficiency.
Use sharp carbide or high-speed steel tools with large positive rake angles to ensure light cutting rather than material extrusion.
PTFE is prone to creep; use low-clamping-stress methods (soft jaws/vacuum suction) and symmetrical layered material removal, with intermediate annealing when necessary.
Allow 24-hour stress relief after final machining before final inspection; batch parts are machined with identical parameters, achieving consistency up to ±0.01mm.
PTFE scratches easily and attracts dust via static; handle with gloves throughout, use dedicated workstations, and ultrasonically clean before shipment.
Besides Bronze Filled PTFE, PTFE (Teflon) offers several other grades with different characteristics. Click to view details.
