AI Technical Summary
When developing, prototyping, or producing polytetrafluoroethylene (PTFE) parts in small batches, there are problems such as high mold costs, poor flexibility, difficulty in clamping during machining, difficulty in controlling precision, and poor dimensional stability.
The blank is cut using a multi-part layout method, combined with vacuum suction cup adsorption clamping and embedded processing. The blank is fixed by vacuum adsorption, and a solid connecting layer is retained during the processing. Finally, the connecting layer is removed to achieve the separation of the part from the blank.
It enables efficient machining of polytetrafluoroethylene (PTFE) parts, with convenient clamping, stable machining accuracy and surface quality, good dimensional consistency, high production efficiency, low cost, and short processing cycle.
