WATER JET CUTTING

• High-pressure water jets are combined into three
  groups
• continuous jets
• pulsed jets
• water cannons

WATER JET CUTTING

• Initially, high-pressure water jets were employed
  for cutting and fracturing rocks, coal and
  various materials in the laboratory.
• Later, field and industrial applications have
  been emerged.

Summary

• Water jets are using in tunneling machines
  head in order to have fast penetration. However
  new cutting heads are designing because of
  decrease of force in cutter tools. In addition
  dust problem is reduced. Water jets are
  especially use in hard rock cutting and researchs
  are target to cut the rock by using just water.
