Achieving high-precision hole positioning with water jet processing.
■Overview of Processing Example Product Name: NBR Rubber Square Packing (with Bolt Holes) / Dimensions: 290W × 300L × 3t, Hole Diameter φ4 × 24 Locations, Inner Dimensions 20W Square Cutout / This processing example is a sealing packing for industrial machinery. It features 24 evenly spaced bolt holes along the outer circumference, allowing for secure attachment to flanges. The water jet processing maintains high positional accuracy for the holes despite being made of rubber, achieving a smooth cutting surface without burrs. ■Product Features NBR (Nitrile Rubber) has excellent oil resistance, making it an ideal synthetic rubber for seals in fuel oils and lubricating oils. It also boasts high mechanical strength and wear resistance, and is widely used in O-rings, packings, hoses, and more. However, it has low weather resistance and ozone resistance, making it unsuitable for outdoor use, and it primarily excels in indoor hydraulic and pneumatic equipment.

basic information
■Processing Method Water jet cutting is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, it is possible to produce high-quality products in a short time. Additionally, the dimensional tolerances that are significantly improved compared to traditional manual processing result in stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet processing. ■Q&A Q: What applications are suitable for NBR rubber? A: Due to its excellent oil resistance, it is ideal as a sealing material for hydraulic equipment and industrial machinery that uses lubricants. Q: What is the positional accuracy of bolt holes? A: Water jet processing significantly improves dimensional tolerances compared to manual processing, achieving stable hole position accuracy. Q: Is it possible to produce in small lots? A: Yes, water jet processing does not require molds, so it can flexibly accommodate from a single prototype to small lots.
