UHMW/Polyethylene Machining

Machining UHMW/Polyethylene is an artform.  UHMW/PE a high level of thermal expansion. Basically, meaning this material will move…. A LOT.  This may make it difficult to hold tight tolerances on UHMW parts that will be exposed to changing temperatures. It takes trial and error, experience, unique feed rates and strategy to attack some designs out of UHMW/Polyethylene.  To hold critical tolerances, it may require allowing the material to stress relieve overnight or longer to develop a strategy to meet critical dimensions and tolerances.

UHMW/PE is a great choice for parts such as conveyor parts, wear pads, wear strips, pulleys, sleeves.  UHMW is often used in food processing parts such as star wheels, rollers, bushings, gears, plugs and handles.  UHMW/PE is also used as MRO parts such as chain guides, wear plates, split bushings and more.

Wear Resistance UHMW Parts!

Weekly, one of our machines will be running a precision component out of UHMW/PE.  From a +/-.002 toleranced UHMW roller to a larger 48” UHMW wear pad.  From CNC turning to CNC milling, we know hot to attack each component designed out of UHMW/PE material.
