Document Type and Number:
Japanese Patent JP2014217921
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that, in a cutting tool configured to support a cutting machine body on a top face side of a base to be contacted to a cutting material, cut the cutting material by a cutting blade projecting to a base lower face side for performing cutting processing, a technique for spraying motor cooling wind to a marking line guide of the base for securing the visibility has been provided, but the technique is not exhibited sufficiently when the cutting machine body is inclined, and achieve the exhibiting of the function for blowing cut powders by the motor cooling wind even when the cutting machine body is inclined.SOLUTION: A wind shielding part S is disposed on a front part of an outlet of the motor cooling wind in a state that it bridges over both sides of left and right with respect to cutting direction. The motor cooling wind blowing to the wind shielding part S is blown to a marking line guide 2a efficiently via a ventilation part 31 where ventilation resistance is smaller. When a cutting machine body 10 is inclined, the motor cooling wind is blown to the wind shielding part S traversing the front part, and then is blown to the marking line guide 2a via the ventilation part 31 efficiently.
