Abstract

A cutting fluid passageway that supplies a cutting fluid is disposed in a machining space (inside of a machine tool) of a machining tool isolated by a cover. The cutting fluid passageway is formed so that the upper portion thereof is opened in the passageway direction. Then, the cutting fluid is supplied from the cutting fluid passageway to a workpiece and a tool during machining or to the inside of the machine tool on which scattered chips produced by the processing are accumulated.

First claim

The invention claimed is:

1. A machining tool, comprising:
a cover that isolates the inside of the machining tool, which is a machining space, from the outside, wherein the machining tool is configured to machine a workpiece by moving a tool attached to a spindle relative to the workpiece set on a table; and
a cutting fluid passageway disposed inside the machine tool and configured to supply a cutting fluid to a predetermined position inside the machine tool on which scattered chips are accumulated by machining,
wherein the cutting fluid passageway extends in a single straight line from a first side of the machining space to a second side of the machining space, the second side opposite to the first side,
wherein the cutting fluid passageway has an end at the second side, and a side portion between the first side and the second side, and
wherein the cutting fluid passageway has an opening in the upper portion thereof and along a passageway direction of the cutting fluid passageway, and is configured to supply both (i) the cutting fluid that overflows from the side portion of the cutting fluid passageway and (ii) the cutting fluid that flows out of the end of the cutting fluid passageway to said predetermined position.

2. The machining tool according to claim 1 ,
wherein the opening is configured to supply the cutting fluid that overflows a side wall of the cutting fluid passageway to said predetermined position.

3. The machining tool according to claim 1 , wherein the predetermined position is located below the cutting fluid passageway.

4. The machining tool according to claim 2 , wherein the predetermined position is located below the cutting fluid passageway.
