AI Technical Summary

Technical Problem

Existing coolant supply systems for rotary cutting tools suffer from centrifugal forces that cause coolant to be accelerated away from the cutting element, leading to non-uniform cooling and reduced efficiency across varying rotational speeds.

Method used

A coolant turbine with an annular body and angled coolant channels that rotate in the opposite direction to the cutting tool, reducing centrifugal forces and ensuring uniform coolant distribution by using the coolant's flow energy to generate rotation.

Benefits of technology

The solution improves cooling efficiency and uniformity across the entire speed range of the rotary cutting tool by minimizing centrifugal forces on the coolant, enhancing the coolant's ability to reach the cutting surface.

Abstract

A coolant turbine (18) for a rotary cutting tool (10) comprises an annular turbine body (22) with a first end face (32), an opposing second end face (34) and a plurality of coolant channels (30) distributed around a central axis of the turbine body (22), wherein the channels (30) have a coolant inlet (36) and a coolant outlet (38), each of which extends at least partially through the turbine body (22) in such a way that the turbine body (22) can be set into rotation by a coolant flow.
