Processing examples of felt gaskets | Responding to multi-hole shapes with water jet processing
■Overview of Processing Example Product Name: Felt Gasket Dimensions: t9 × Outer Diameter φ160 × Inner Diameter φ54 (P110, 4 holes) This processing example involves the machining of a circular gasket made from felt material. In addition to the ring shape with outer and inner diameters, it features a structure with multiple mounting holes arranged in the circumferential direction, intended for applications such as cushioning, dust prevention, and sound absorption within equipment. Specifications require shape accuracy and reproducibility of hole positions. The client’s industry is related to industrial machinery. The characteristic of this product is its use as a gasket that takes advantage of the unique flexibility and porous structure of felt material. It is adopted to ensure compatibility with the counterpart components while protecting internal parts. The processing method employed is water jet cutting. Since felt material tends to fray and exhibit dimensional variations with blade processing, non-contact processing is used to cut the shape, allowing for stable machining of the outer diameter, inner diameter, and multi-hole shapes according to the drawings. This contributes to preventing positional misalignment during assembly and improving reproducibility.

basic information
■Product Features (Felt) Felt is a sheet-like material made by intertwining fibers, characterized by its porous nature which provides good breathability and water permeability, and resistance to fraying. It excels in cushioning, sound absorption, thermal insulation, and oil absorption, and is widely used for shock absorption, noise prevention, industrial gaskets, abrasives, and even for exhibition decorations. ■Processing Method (Water Jet Cutting) Water jet cutting is a method that uses high-pressure water to cut materials. It works by spraying high-pressure water for processing. The injection nozzle can be changed according to the processing material, allowing for the production of high-quality products in a short time. Additionally, the dimensional tolerances that are typically associated with manual processing are significantly improved, resulting in stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet cutting.
