Frequently Asked Questions About Water Jet Cutting Metals

Q: What is water jet cutting?

A: Water jet cutting is a technology that uses high-pressure water mixed with abrasive particles to cut through metal. Think of it as a super-powered water stream that can slice through metal with precision, without generating heat.

Q: What types of metal can be cut with a water jet?

A: Water jets can cut virtually any metal, including stainless steel, aluminum, titanium, copper, brass, and tool steel. It's versatile enough to handle both soft and hard metals.

Q: How thick can water jets cut?

A: Water jets can cut metal up to 300mm (12 inches) thick, depending on the material. Common thicknesses are:

  • Stainless Steel: up to 300mm
  • Aluminum: up to 200mm
  • Titanium: up to 150mm

Q: Does water jet cutting affect the metal's properties?

A: No, water jet cutting doesn't affect the metal's properties because it's a cold-cutting process. There's no heat-affected zone, no thermal distortion, and no change in the metal's strength or hardness.

Q: How precise is water jet cutting?

A: Water jet cutting is highly precise, typically achieving accuracy within ±0.1mm (0.004 inches). This makes it suitable for projects requiring tight tolerances.

Q: Will the cut edges be smooth?

A: Yes, water jet cutting typically produces smooth edges that often don't require additional finishing. The surface finish quality can be adjusted by controlling the cutting speed.

Q: How long does water jet cutting take?

A: Cutting time varies based on material thickness and type. For example:

  • 1/4" steel: 100-150 inches per minute
  • 1/2" aluminum: 50-75 inches per minute
  • 1" stainless steel: 15-25 inches per minute

Q: Is water jet cutting expensive?

A: While initial equipment costs are significant, operating costs are often competitive, especially for thick materials or complex cuts. The lack of need for secondary finishing often makes it cost-effective in the long run.

Q: Can water jet cutting create detailed designs?

A: Yes, water jet cutting can create intricate designs and complex patterns in metal. It's capable of cutting sharp corners, small holes, and detailed geometries with high precision.

Q: Is water jet cutting safe for the environment?

A: Yes, water jet cutting is environmentally friendly. It uses natural garnet abrasive, produces no hazardous fumes, and the water can be recycled. The process doesn't create toxic waste or air pollution.
