Method for High-Pressure Liquid Jet Deburring and Corresponding Industrial Installation

A method for high-pressure liquid jet deburring comprising:

• positioning a workpiece inside a deburring receptacle by a positioning device, the workpiece having at least one machined portion from which burr is to be removed;
• deburring the machined portion by a high-pressure/high-speed liquid jet from a high-pressure jet nozzle while at least the machined portion is dipped in liquid;
• flooding the deburring receptacle prior to deburring with cleaning liquid via a flooding inlet of the deburring receptacle;
• and
• deburring the machined portion after flooding by a high-pressure/high-speed liquid jet without gas sheath, such that the high-pressure/high-speed liquid jet and at least the machined portion are immersed in a bath of cleaning liquid during deburring.

An apparatus for high-pressure liquid jet deburring comprising:

• a high-pressure jet nozzle connected to a high-pressure liquid circuit for deburring a machined portion of a workpiece, from which burr is to be removed, by high-pressure/high-speed liquid jet;
• at least one deburring receptacle for containing a bath of cleaning liquid during operation and for receiving at least part of the workpiece;
• and
• a positioning device for positioning the workpiece relative to the high-pressure jet nozzle;
• wherein the deburring receptacle has a flooding inlet connected to a cleaning liquid supply circuit and suitable for flooding the deburring receptacle with a cleaning liquid;
• and
• the high-pressure jet nozzle is arranged in the receptacle and configured for creating an immersed high-pressure/high-speed liquid jet without gas sheath.
