PEEK
PEEK can be machined for a variety of applications due to its exceptional properties. Compared to other technical polymers, PEEK has few drawbacks. Its resistance to high temperatures is one of its key features, as it can withstand high temperatures for longer periods of time than most other polymers.This makes it an excellent choice for CNC plastic machining.
Additionally, PEEK is hydrophobic, which means it does not readily absorb water. It also emits very little gas when in a vacuum, making it quite advantageous. PEEK can be used for a variety of applications, from temporary implantation in patients' bodies to aerospace parts subjected to extremely low vacuums.
PEEK components are naturally opaque, and their structure makes it challenging for paints and coatings to adhere to their surface. However, due to its natural resistance to chemicals, it is frequently permissible to leave parts in their machined state. PEEK is easily machined and can achieve smooth surface finishes.Any undesirable tool marks can be removed by mechanically abrading the surface with glass beads.
The high cost of the material necessitates a reduction in manufacturing overhead expenses. Requesting annealing during fabrication is one way to reduce the cost of CNC machining in PEEK. Surface and interior cracking may be decreased as a result, which will lower the scrap rate and lower overall costs for the producer.
