On-Demand Webinar:

Machine Tools & Metal Working

Date: June 6, 2012
Time: 2 PM EDT (11 AM PDT)
Duration: 0.5 hour


This presentation will start with a brief overview of waterjet cutting technology and its use in manufacturing applications. This will be followed by a more detailed discussion of the two predominant types of ultra-high pressure pumps used in waterjet cutting-the hydraulic intensifier and the direct-drive triplex pump. The speaker will explain how these pumps operate and compare their relative strengths and limitations. He will also discuss the impact of pressure on cutting speed and operating cost. The presentation will conclude with guidelines for pump and operating pressure selection based on the particular cutting application of interest.

Key Take-Aways

  • An understanding of the range of applications of waterjet cutting in manufacturing.
  • An understanding of the two basic types of ultra-high pressure pumps used in waterjet cutting systems and their relative strengths and limitations.
  • An understanding of the relative roles that increased pressure and/or increased power play in waterjet cutting speed, both for pure waterjets and for abrasive waterjets
  • An understanding of the basic guidelines for selecting the optimum type of pump and operating pressure for particular waterjet cutting applications
