- the present invention relates to a tool with a chip guide used for cutting, and more particularly to a tool with a chip guide suitable for cutting with a small depth of cut or cutting of a highly ductile material, and a lathe.
- Chips generated by the lathe cutting process are spirally curled and thus easily entangled with tools and workpieces, which is a major factor that hinders lathe automation.
- a certain result has been obtained for preventing entanglement of the tool and workpiece by cutting the chips using a chip breaker.
- the chip breaker further breaks and divides the chip by further strengthening the curl of the chip, for example, when the cutting amount is small, the chip is highly flexible and easily curled. Difficult to break with a chip breaker.

For this reason, the efficiency of conveying chips to the exit side of the guide path is reduced, and the amount of forced exhaust fluid consumed is very large in order to reliably discharge a large amount of chips. Further, when the forced discharge fluid flow is turbulent, the effect of extending the chips straight is low, and the curled chips are likely to be caught on the inner wall of the guide path.

Since the fluid supply port is inclined toward the outlet side of the chip guiding path, the supplied fluid flows to the outlet side of the chip guiding path. Due to the flow of the fluid, a negative pressure is generated on the inlet side of the chip guide path, and chips generated at the blade portion of the cutting tool are sucked into the chip guide path from the inlet located near the blade section. The sucked chips are guided to the outlet side along with the fluid while being extended, and are discharged from the outlet.
