What is a water jet cutter?
What is a water jet cutter? I believe that many friends do not know, today we mainly learn about the water jet cutting machine through the following contents.
The water jet cutting machine consists of three parts: ultra-high pressure water jet generator (high pressure pump), CNC machining platform, and jet cutting head.
1. Ultra-high pressure water jet pump (high pressure pump)
As the power source of the water jet, the common technical solution is that the hydraulic motor drives the supercharger to generate ultra-high pressure water jet. The pressure of ordinary tap water is raised to tens to hundreds of MPa (1MPa is about 10bar), and it is ejected through the jet nozzle with extremely high kinetic energy.
2. CNC machining platform
The CNC water jet is mainly used to cut flat plates. The cutting platform adopts rolling linear guides and ball screws as the transmission. Under the precise control of the numerical control program and the control motor, the X-axis and the Y-axis move independently or two-axis linkage, and drive the cutting head to realize straight lines and arbitrary curves. cut.
The high-pressure pump can only achieve the cutting function through the beam nozzle. The size of the nozzle aperture determines the pressure level and flow rate. At the same time, the nozzle also has the function of gathering energy. There are two basic forms of jet cutting head: one is for pure water cutting, and the other is for abrasive cutting. The cutting head with abrasive cutting is based on the pure water cutting head, plus an abrasive mixing chamber and a hard nozzle.
