Waterjet cutting employs a high-pressure stream of water, often mixed with abrasive materials, to cut through materials. This method is effective for creating holes and intricate shapes without generating heat.
- Advantages:
- Cold Cutting: No heat-affected zones, preserving material properties.
- Material Range: Cuts metals, stone, glass, and more.
- Environmentally Friendly: Uses water and natural abrasives.
3. Electrical Discharge Machining (EDM)
EDM uses electrical discharges to erode material, making it suitable for conductive materials. It is particularly effective for hard metals and complex shapes.
- Advantages:
- Complex Shapes: Capable of producing intricate geometries.
- Hard Materials: Works well on tough metals.
- Precision: Offers high accuracy and fine surface finishes.
4. Ultrasonic Machining
This technique uses high-frequency ultrasonic vibrations to remove material. It is suitable for brittle materials like glass and ceramics.
- Advantages:

- Brittle Materials: Ideal for glass, ceramics, and hard stones.
- Smooth Finish: Produces fine surface quality.
5. Plasma Cutting
Plasma cutting uses a jet of ionized gas to cut through electrically conductive materials. It is a fast and efficient method for cutting thick materials.
- Advantages:
- Speed: Quick cutting of thick metals.
- Versatility: Cuts a variety of conductive materials.
- Cost-Effective: Lower operational costs compared to some alternatives.
