AWJ Cutting Head


At dti Exact™, we manufactured the waterjet cutting head, highlighted here, for use in high pressure abrasive cutting applications. Our state-of-the-art equipment, combined with our workforce of technically experienced machinists and qualified assembly professionals, enabled us to manufacture this cutting head with exceptionally close ±.0005″ tolerances ensuring perfect jet stream alignment for precision performance and reliability.

Working with the customer-supplied drawing, we used our CNC lathe to machine the intricate angles, curves, and bores of the cutting head body from 1-3/8″ diameter 17-4 PH stainless steel round bar. Our precision machining capabilities allowed us to achieve smooth cutting accuracy and a 16 surface finish on this high strength material. We coordinated the procurement of the B.O.M. components to ensure a continuous and steady flow of parts into the assembly process, where our technicians followed a detailed set of engineering drawings to create the finished product.

We integrated quality control into every step of the production process. Extensive QA testing ensured that the precision and quality of the waterjet stream would make precise cuts, rapidly, accurately, and repeatably throughout an extended service life.

Waterjet cutting is a precise manufacturing technique used by many industries for the cutting and shaping of tight tolerance components. The quality of the cutting head is critical to high performance operations. By engineering consistent quality into all machining and assembly processes, we continue to satisfy the exacting demands for manufacturing this vital component.
