Water-jet Cutting

Zhongsen Editor 2016-11-23

Water-jet cutting, also known as water cutting, namely high pressure water jet cutting technology. Water-jet cutting is a generic term used to describe equipment that uses a high pressure stream of water for cutting or cleaning purposes. It uses the supercharger to pressure water up to 10Mpa even more higher pressure and then shot out of from small nozzle. This pressure will be converted to kinetic energy and forming a high speed jetting.Cutting uses the damage effect of high-speed jet kinetic energy on parts to achieve the goal of cutting and shaping.Water-jet usually used in abrasive cutting of quartz sand, garnet, river sand, corundum, etc. The particle size of abrasives usually is 40-70 mesh, the higher the hardness of the abrasive grain size, the greater the cutting ability is stronger. As its low cost, easy to operate and higher rate of good products, the water-jetting cutting technique is becoming the mainstream of industrial cutting technology.

Classification:

According to the situation of adding sand: water-jet cutting is divided into the non - sand cutting and the sand cutting.

According to the equipment: it was divided into large water-jet cutting and small water cutting.

According to the pressure: it was divided into high pressure and low pressure, generally 100MPa as the boundaries. More than 100Mpa for high pressure type, less than 100Mpa for low pressure type. And more than 200Mpa for ultrahigh pressure type.

Based on the technical principle: it is divided into the front mixed type and the back mixed type.

According to the safe situation: it was divided into safe cutting and non-safe cutting class, main difference on the pressure, less than 100Mpa type low pressure water cutting can be applied to special industry such as: dangerous chemical, petroleum, coal, hazards, etc.

Water-jet cutting characteristics:

1, CNC forming all sorts of complicated design;

2, A cold cutting, will not produce thermal deformation or thermal effect;

3, Environmental protection, no pollution, will not produce poisonous gas and dust;

4, Processing all kinds of high hardness materials, such as: glass, pottery and porcelain, stainless steel, etc., or relatively soft material, such as leather, rubber, paper diaper, etc;
5, The only way of complex processing of the composite material, ceramic material:

6, No secondary processing as its incision smooth, without slag;

7, A complete work of drilling, cutting, forming;

8, The low cost of production; The high degree of automation; Working continuously for 24 -hour

Water-jet cutting application range:

(1) The roughness of the cutting metal is 1.6μm, and the cutting precision is about 0.10mm, which can be used for precision forming and cutting;

(2) It has the unique feature of non-ferrous metal and stainless steel cutting, no reflective effect and edge loss;

(3) Composite material, composite metal, forming cutting of different melting point of metal complexes and non metal;

(4) The cutting of low melting point and flammable materials, such as paper, leather, rubber, nylon, wool felt, wood, explosive and so on;

(5) The cutting under the special space and environment: underwater, flammable gas environment;
(6) High hardness and unsolvable material cutting: stone, glass, ceramics, hard alloy, diamond, etc.
