あり高価である。(Conventional technology) To lubricate rotary cutting tools such as drills and end mills, a lubrication pipe is led from the outside and the lubrication port of the lubrication pipe is directed toward the cutting part, or a lubrication hole is drilled in the rotary cutting tool itself. There was one (Japanese Utility Model Publication No. 15946/1983) in which the oil supply hole and the oil supply path provided in the chuck were communicated. With the former, when the part to be machined changes or the tool is replaced, the oil filler port must be adjusted by hand each time, and depending on the workpiece, parts with plate-like protrusions may be placed between the tool and the oil supply pipe. Enter,
Sometimes it even interfered with lubrication. The latter has a complicated structure and is expensive.

However, with just a slight modification to the conventional chuck, a rotary cylinder is inserted into the chuck cylinder through a large number of needle rollers arranged with an axis inclined with respect to the axis of the chuck body. To provide a chuck that can be easily lubricated without impairing gripping force.

果を奏する。(Structure and Effects of the Invention) The present invention includes a chuck main body having a shank that fits into a spindle of a machine tool at one end, a chuck tube at the other end, an n1 rotating tube fitted into the outer peripheral surface of the chuck tube, and a chuck tube. and a needle roller that is held with an axis inclined to the axis of the n1 chuck body, which is interposed between the rotary cylinder and the n1 chuck body. In a needle roller type chuck with a hole drilled in the body, a lubricating device is inserted into the main body, and one or more of the hollow holes are connected to the lubricating hole of the lubricating ring, so that
Lubrication is possible without any special equipment by simply communicating a part of the hollow hole with the oil supply hole of the oil supply device, and chipping of the cutting edge can be prevented, resulting in extremely good machined surface roughness and smooth Even if there are many changes, sufficient oil can be supplied. Moreover, the gripping force of the tool does not decrease at all. Further, since the structure is simple, high-precision processing is possible, and it is inexpensive, and has many excellent effects.

The chuck body (1) consists of a shank (2) that can be attached to the main shaft, a collar part (3), a cylindrical part (4) for attaching an oil supply ring, and a chuck cylinder (5) for holding a tool. A plurality of hollow deep holes (8) are bored in the cylindrical part (4), the chuck cylinder (5), and the thick wall part (6) of the chuck cylinder, and one or several of the hollow holes are bored. A horizontal hole (9) is bored in the outer periphery of the cylindrical portion (4) to form an oil reservoir.
