TECHNI Waterjet Parts: Forging the Soul of Cold Cutting with Precision Engineering
In the field of industrial cutting, waterjet technology has become a core processing method for numerous industries due to its wide material applicability, absence of heat-affected zones, environmental friendliness, and high efficiency. Behind this, TECHNI Waterjet Systems, through its deep cultivation and innovation in core parts, has not only propelled the advancement of waterjet technology but also ensured the long-term and stable operation of its equipment worldwide.
Superior performance stems from the relentless pursuit of perfection in every single part.
I. Core Technologies: Precision Parts Drive Technological Innovation
Every leap in waterjet technology is inseparable from breakthroughs in core parts. TECHNI deeply integrates ultra-high pressure waterjet technology, abrasive jet technology, and dynamic waterjet technology, all supported by a series of rigorously tested and precisely calculated parts.
Ultra-High Pressure Power Heart: Core components within the ultra-high pressure pump, such as the Ceramic Plunger, Low-Pressure Cylinder Liner, and Piston, act as the heart of the system. They work together to pressurize ordinary water to 55,000 PSI or even higher, forming an ultra-high velocity stream capable of cutting almost any material. Among them, the Ceramic Plunger ensures stable output under prolonged high pressure due to its extremely high wear and corrosion resistance.
Abrasive Acceleration System: The key to abrasive cutting capability lies in the Abrasive Mixing System. The precise coordination of the Venturi-style Mixing Chamber, Gemstone Nozzle, and Precision Abrasive Tube allows the high-pressure water stream to uniformly mix with garnet abrasive, forming an efficient abrasive jet. The geometric accuracy and material hardness of these parts directly determine the kerf width, taper, and surface finish of the cut.
Dynamic Control and Precision Compensation: The advanced 5-Axis Dynamic Cutting Head, through the linkage of the B-Axis (±60°) and C-Axis (continuous rotation), adjusts the jet angle in real-time to compensate for the natural taper formed during cutting. This not only solves the long-standing industry problem of "Taper" but also ushers waterjet cutting into a new era of micron-level precision machining.

These parts, though small, are crucial. Taking the Gemstone Nozzle as an example, its orifice diameter is merely a fraction of a millimeter, yet it must withstand instantaneous pressures exceeding 600 MPa. The hardness, toughness, and manufacturing precision of its material directly determine the fineness of the cut line and its service life.
