In ultra-precision lathes, cutting fluid is atomized and sprayed toward the tip of the cutting tool from a nozzle placed near the cutting tool during machining. The cutting fluid and the pressurized air that injects the cutting fluid have the effect of cooling down the heat generated at the cutting edge of the cutting tool that occurs during machining, or forcibly removing chips, but this is not always sufficient and there are In some cases, the tiny chips that were generated were wrapped around the tip of the cutting tool, causing scratches on the surface of the workpiece. For this reason, the cutting fluid removal efficiency has conventionally been increased by controlling the jetting direction of the cutting fluid. That is, the direction in which the cutting fluid is sprayed is determined by changing the direction of the nozzle that sprays the cutting fluid. However, in this method, the pressurized air and cutting fluid ejected from the nozzle diffuse as they go from the nozzle to the tip of the cutting tool, so that it was insufficient to remove chips wrapped around the cutting edge of the cutting tool.

〔考案の目的〕[Purpose of invention]

In order to achieve the above object, in this invention, a guide piece is provided in the cutting tool holder, and this guide piece directs a flow of pressurized air that sprays cutting fluid toward the machining part toward the cutting edge of the cutting tool. It is characterized by eliminating chips that wrap around the cutting edge.

A chuck 1 holds a workpiece 2 by blowing.
The cutting tool 3 is held by a pin 6 of a clamper 5 provided on a cutting tool holder 4. The guide piece 7 is fastened onto the clamper 5 with a bolt 8. This guide piece 7 has an inclined surface 9 at one end. A nozzle 10 atomizes cutting fluid containing pressurized air and sprays it toward the cutting edge of the cutting tool.

With the above configuration, pressurized air containing cutting fluid is injected from the tip of the nozzle 10 toward the cutting edge of the cutting tool 3. At this time, the pressurized air injected from the nozzle 10, diffused, and brought into contact with the inclined surface 9 of the guide piece 7 flows along the inclined surface 9 between the workpiece 2 and the guide piece 7. Therefore, the flow rate of the pressurized air flowing near the cutting edge of the cutting tool 3 increases, so that minute chips wrapped around the cutting edge of the cutting tool 3 can be forcibly removed, eliminating scratches etc. that occur on the workpiece. be able to.

As described above, according to the present invention, a guide piece having an inclined surface for changing the flow direction of compressed air ejected from a nozzle disposed in the vicinity of the guide piece is attached to the tool holder. Since it is provided in an adjustable manner, it is possible to easily adjust the cutting fluid supply state according to the machining conditions without adjusting the position of the nozzle.
