Problems solved by technology
Therefore, the efficiency of conveying the chips to the exit side of the guide path is low, and in order to reliably discharge the chips generated in large quantities, the consumption of forced discharge fluid becomes very large.
In addition, if the flow of the fluid for forced discharge is turbulent, the effect of straightening the chips is low, and the remaining curled chips are likely to be caught on the inner wall of the guide path.

Embodiment Construction
[0030] and Figure 1 to Figure 4 The first embodiment of the present invention will be described together. Such as figure 1 and figure 2 As shown, the tool 1 with a chip guide includes a cutting tool 2 that is turned in contact with a rotating workpiece W, and chips C generated by turning the cutting tool 2 ( figure 2 ) The chip guide 3 guided to a position away from the workpiece contact portion of the cutting tool 2 and the forced discharge of the fluid for forcibly discharging the chips C in the chip guide path 5 described later of the chip guide 3 to the outlet side Use the fluid supply mechanism 20. The cutting tool 2 of the illustrated example is a cutting tool composed of a shank 2 a and a blade 2 b attached to the tip of the shank 2 a.
[0031] The chip guide 3 has a surface on which the blade portion 2b is fixed to the shank portion 2a of the cutting tool 2 ( figure 1 , figure 2 The block-shaped guide body 4 on the upper surface in the middle is formed with a...

The disclosed tool (1) with a swarf guide is provided with: a cutting tool (2) having a blade part (2b) contacting the workpiece (W); a swarf guide (3) having a poriform swarf guide path (5) with an inlet (5) positioned near the blade part (2b) and an outlet (7) positioned at a distance from the blade part (2b); and a discharge-forcing fluid supply means (20) which supplies a fluid from the middle of the swarf guide path (5) towards the outlet (7). In the inner wall of the swarf guide path (5), the discharge-forcing fluid supply means (20) has a fluid supply port (15) which opens at an incline towards the outlet (7) of said swarf guide path (5). Said fluid supply port (15) is shaped so as to open around the entire circumference of the inner wall of the swarf guide path (5), or shaped so as to open at multiple positions distributed around the circumference thereof.
Description
[0001] This application claims the priority of Japanese Patent Application No. 2010-206315 for which it applied on September 15, 2010, All these are used by reference as the content which comprises a part of this application. technical field [0002] The present invention relates to a tool with a chip guide for cutting, and more particularly to a tool with a chip guide and a lathe suitable for cutting with a small amount of cut or cutting of a material with high toughness. Background technique [0003] Chips generated by cutting on a lathe are curled in a helical shape, so they tend to get entangled on a tool or a workpiece, and this is a major obstacle to the automation of a lathe. With regard to chips of a workpiece made of a material with low toughness, conventionally, cutting the chips by using a chip breaker has a certain effect in preventing entanglement on the tool or the workpiece. However, since the chip breaker is a device that breaks and cuts the chips by further ...
