- the adjusting nozzle member 16 acts to restrict the flow of the cutting fluid mist from the inside of the mist supply pipe 14 into the front-rear through-hole h1 to a certain extent.
- the cutting fluid mist arrives at an appropriate flow rate into the front-rear-facing through hole h1, and then is ejected from the outlet openings j1, j1 at the tip of the cutting tool 17 through the mist passage j of the cutting tool 17.
- the jetted cutting fluid mist lubricates the frictional portion between the cutting tool 17 and the work without excess or shortage, and cools it so as not to be overheated.
- the cutting fluid mist flowing out of the adjusting nozzle member 16 flows through the front-rear through-hole h 1 of the cutting tool locking member 20 and the outer periphery of the small-diameter pipe portion 14 b. Attempts to leak to the atmosphere through the annular gap formed between the tool holder 8 and the main shaft 2 due to the hermetic connection between the tool holder 8 and the main shaft 2. Further, the ring-shaped sealing member b prevents the outflow from the back of the insertion hole 2a to the rear.
- the cutting fluid mist flowing out from the outlet opening j1, j1 on the cutting edge of the cutting tool 17 tends to be liquefied due to pressure changes, speed changes, centrifugal force, etc., but the mist is supplied from the rear of the spindle 2.
- the cutting fluid mist up to the tip of the pipe 14 suppresses large pressure changes and speed changes because the mist supply pipe 14 and the adjustment nozzle member 16 are arranged straight and held in a non-rotating state. As a result, the liquefaction is effectively suppressed by not receiving any centrifugal force due to the rotation of the main shaft 2.
- the cutting fluid mist flowing out of the adjusting nozzle member 16 is in front of the cutting tool locking member 20. It flows out through the rear facing through hole h1 and the mist passage j of the cutting tool 17.
- the cutting fluid mist flows without receiving a large flow resistance.
- the through hole h1 and the mist passage j are located at the center of rotation of the tool holder 8 and their length is shorter than the length of the main shaft, and even if the diameter is larger than the nozzle hole e.
- the cutting fluid mist flowing through the front-rear through-hole h 1 and the mist passage ⁇ generates a large centrifugal force due to the 8 rotations of the tool holder. It is not received for a long time. Therefore, liquefaction of the cutting fluid mist in the front-rear through hole h1 and the mist passage ⁇ is also effectively suppressed.
- the cutting fluid mist ejected from the tip end face of the cutting tool 17 may be excessive or too small.
- By performing the replacement work by removing the nozzle by e.g., another adjustment nozzle member 16 having a separately prepared nozzle hole e of a different diameter is newly mounted.
- the restricting action on the flow of the cutting fluid mist by the adjusting nozzle member 16 differs, and the flow rate of the cutting fluid mist ejected from the tip end surface of the cutting tool 17 is optimized.
- the adjusting nozzle member is replaced and mounted with another one, so that the cutting nozzle mist can be removed from the tip end face of the cutting tool. It is possible to arbitrarily change the flow rate of the cutting fluid mist to be ejected, so that an optimal amount of cutting fluid mist can be supplied to the tip of the cutting tool in machining under various machining conditions, It is possible to prevent waste and contamination of the working environment due to cutting fluid mist.
- the tool holder can be attached and detached while the adjustment nozzle member is fixed to the mist supply pipe.
- the replacement mounting of the aligning nozzle member can be easily performed by removing the tool holder from the spindle. Furthermore, it can be realized only by changing the tip of the mist supply pipe in the conventional spindle device.
- the flow rate of the cutting fluid mist ejected from the tip end surface of the cutting tool can be effectively changed. Becomes possible.
