Title: Christian Henry Passow: Innovator in Cryogenic Cooling Technologies
Introduction
Christian Henry Passow is an accomplished inventor based in Etna, NH (US). He holds 2 patents that focus on innovative solutions for cryogenic cooling in machining processes. His work has significantly contributed to advancements in the efficiency and effectiveness of cutting tools.
Latest Patents
One of Passow's latest patents is a "Device for axial delivery of cryogenic fluids through a machine spindle." This invention allows cryogenic fluids to be delivered along an axial path through a machine tool spindle to a cutting tool mounted in a standard tool holder. An external source of cryogen is delivered via an insulated line to a junction block housing, where the cryogen flows into a vacuum insulated coolant delivery tube mounted on the spindle's axis. This system ensures that the coolant delivery tube can be safely disconnected from the cryogenic manifold before a tool change operation, effectively turning off the flow of cryogen.
Another notable patent is for an "Indirect cooling of a rotary cutting tool." This system utilizes a cryogenic coolant delivered to a cavity formed on the back surface of the cutting element, providing cooling near the cutting edge. The low flow rate of the working fluid allows it to be safely vented to the atmosphere, eliminating the need for specialized coolant recovery or ventilation equipment. This innovative approach is particularly beneficial for machining hard-to-machine metals and composites, as well as conventional materials without traditional cutting fluids.
