Machine tool
First Claim
1. A machine tool comprising:
- a moving portion configured to move within a machining area;
a fixed portion provided within the machining area;
a line-shaped member having elasticity, the line-shaped member having one end side fixed to the moving portion and another end side fixed to the fixed portion; and
an interference portion provided within the machining area, wherein, when the moving portion is moved in a direction to come close to the fixed portion, the line-shaped member is bent and then a portion of the line-shaped member is brought into abutment against the interference portion;
wherein a friction reduction portion is provided at a portion of the interference portion against which the line-shaped member is brought into abutment, and is configured to reduce friction between the interference portion and the line-shaped member when the line-shaped member is moved relative to the interference portion in a state of being held in abutment against the interference portion, wherein;
the moving portion is a spindle head configured to move in a vertical direction;
the line-shaped member is a supply pipe configured to supply cutting fluid; and
the interference portion is a cover configured to cover the machining area.

Abstract
A machine tool is equipped with a second supply pipe having elasticity and having one end side fixed to a spindle head and the other end side fixed to an arm portion, a cover provided within a machining area, and rollers. When the spindle head is moved in a direction to come close to the arm portion, the second supply pipe is bent and then a portion of the second supply pipe is brought into abutment against the cover. The rollers are provided at a portion of the cover against which the second supply pipe is brought into abutment, and are configured to reduce friction between the cover and the second supply pipe when the second supply pipe moves relative to the cover in an abutment state against the cover.
