Customer problems:

Suzhou medical instrument co., ltd is a sino-foreign joint venture orthopedic medical instrument manufacturer and a member of orthopedic director committee of China medical instrument association and China medical instrument research institute. The company mainly produces artificial hip joint series, spinal internal fixator series, locking intramedullary nail series, plate screw series, nickle titanium memory alloy ring device series and metal plate, nail and needle series. The main materials used in its products are titanium alloy and other special alloys. However, titanium alloy is difficult to machine,.Because titanium has high chemical reactivity, it is easy to react with oxygen, nitrogen and hydrogen in the air, resulting in material performance degradation. At the same time, problems such as high local temperature leading to fast tool wear and low machinability will occur in conventional cutting, resulting in great processing difficulty and high processing cost.

Solutions:

Waterjet cutting of  hard materials needs to add abrasive into the waterjet. High pressure water is turned into the energy carrier,  which accelerates abrasive grinding particles like small bullet shots to the cut material, resulting in the formation of high-speed abrasive effect. Because all objects can be worn, the abrasive waterjet can cut any material, of course, including titanium alloy. In addition to energy transfer, water can also quickly take away the heat generated by the impact of abrasive particles on the workpiece, so the waterjet will prevent the workpiece from thermal deformation, thermal stress, metallographic structure changes, microcracks.As a comparison, other thermal processing is usually difficult to avoid the thermal effect. Waterjet cutting is the only cold high-energy beam processing method.

Winning factors:

Lionstek waterjet uses a high energy beam machining control method that takes the jet exit point as the control target, This control method, according to the movement of the jet exit point under the machining surface along the cutting path. chooses optimization strategy determine the movement trajectory of multiaxis, and effectively eliminate the geometrical errors caused by the jet dragging and the kerf taper error

Values for the customer:

Lionstek five-axis smart waterjet equipment has injected new vitality into the waterjet industry, bringing people with a new understanding of waterjetcutting, speed optimization, precision cutting, simplicity operation, error compensation.
