Abstract

A cutting fluid jet machine includes: a cutting fluid jet nozzle; a nozzle-angle adjusting servo motor; a nozzle-length adjusting servo motor; a nozzle-location calculating unit; and a nozzle controlling unit for controlling an angle and a length of the cutting fluid jet nozzle in accordance with movement of a machine tool in a spindle direction based on a nozzle location calculated by the nozzle-location calculating unit.

First claim

The invention claimed is:

1. A cutting fluid jet machine disposed near a spindle of a machine tool and configured to supply cutting fluid onto a tool and a tool holder held by the spindle, the cutting fluid jet machine comprising:
a cutting fluid jet nozzle having a variable jet angle and a variable nozzle length and configured to eject the cutting fluid onto a cutting point of a workpiece as an object of the tool;
a nozzle-angle adjusting servo motor configured to change the jet angle of the cutting fluid jet nozzle in ejecting the cutting fluid onto the cutting point;
a nozzle-length adjusting servo motor configured to change the length of the cutting fluid jet nozzle in ejecting the cutting fluid onto the cutting point;
a nozzle-location calculating unit for obtaining an angle and a length of the cutting fluid jet nozzle based on a travelling amount of the cutting fluid jet nozzle in an axial direction of the spindle, and a length and a radius of a tool to be used; and
a nozzle controlling unit for controlling the angle and the length of the cutting fluid jet nozzle in accordance with movement of the tool in the axial direction of the spindle based on a nozzle location calculated by the nozzle-location calculating unit.

2. The cutting fluid jet machine of claim 1 , further comprising:
a cutting fluid jet nozzle travelling rod configured to change a location of the cutting fluid jet nozzle in a circumferential direction of the spindle; and
a servo motor for the cutting fluid jet nozzle travelling rod, the servo motor being configured to change the location of the cutting fluid jet nozzle in the circumferential direction of the spindle in ejecting the cutting fluid onto the cutting point.

3. The cutting fluid jet machine of claim 1 , wherein the cutting fluid ejected from the cutting fluid jet nozzle is air or oil mist air.
