Hardest Materials vs 60,000 PSI Waterjet
In this captivating YouTube video titled "Hardest Materials vs 60,000 PSI Waterjet," the creators explore the astonishing power of a waterjet cutter as they test various tough materials such as obsidian, quartz, topaz, and a specially selected ceramic composite. With the ability to exert intense pressure—60,000 PSI—this waterjet not only cuts through but also reveals the extraordinary characteristics of these challenging materials .
### Overview of Materials Tested
The video introduces the Mohs scale of hardness, ranging from talc (1) to diamond (10), thereby providing context for the materials being tested. Here’s a quick rundown of the materials explored:
  • Obsidian (approximately 6 on the Mohs scale): Used as the baseline for the tests as the softest material in the group.
  • Quartz (7): Able to scratch obsidian but itself is scratched by topaz.
  • Topaz (8): Demonstrates a significant level of hardness, capable of scratching both obsidian and quartz.
  • Ceramic Composite: This material surpasses topaz, presenting the most difficulty during the test, as it begins to wear down the topaz itself.
### The Waterjet Cutting Test
Throughout the video, the team conducts a series of cutting tests, maintaining a consistent speed and pressure for each material. They aim to analyze cut quality and the level of damage incurred during the cutting process. The use of garnet abrasive in the waterjet enhances the cutting capabilities, demonstrating both sophistication in technique and technology .
#### Key Findings:
1. Cut Quality: The results showcase that while obsidian yields a clean cut, quartz exhibits minor rough edges. The hardest materials, topaz, and the ceramic composite resist the waterjet significantly more, proving the validity of the Mohs hardness distinctions.
2. Speed Adjustments: The team notices that, to achieve optimal cut quality, the cutting speed must be reduced drastically, especially when transitioning from softer to significantly harder materials.
3. Cost Analysis: The video also touches on the operational costs of waterjet cutting, estimating around $100 per inch when cutting hard materials, due to the increased time and wear on the equipment .
As the video concludes, viewers are invited to reflect on the marvels of material science and the innovative applications of waterjet technology. The experiment drastically illustrates how the hardness of materials truly affects cutting efficiency and quality.
