たものである。As shown in FIGS. 1 to 3, this type of perforation device that has already been proposed has a cylindrical collector outer cylinder (a) with a hole (a) for each cutting oil inlet (b) and each drain outlet. C, the collector outer cylinder a is fitted with a wheel e having grooves d, and the collector outer cylinder a is positioned on both sides of the wheel e.
Seal supports g with built-in oil seals f and bearings such as ball bearings are provided in such a way that they do not come out outward, and the main shaft i is brought into contact with each of the oil seals f on each bearing. A connector sleeve j and an inner cylindrical body k are attached to one end opening of the main shaft i.

On the other hand, an injection hole q communicating with the oil filler port is formed in a part of the main shaft i so as to communicate with the supply passage 1, and an outflow hole r1 is formed in the base of the boring head p. and a reflux hole r2, and a tip ejector (tip reflux hole) S is provided at the tip of the inner cylinder body, and a rear end ejector (rear end inflow hole) T is provided at the rear end of the inner cylinder body. It is something that

The main shaft i is rotated by a drive shaft (not shown), and the boring head p, which is integrated with the main shaft i, is rotated to start drilling into the workpiece W. At the same time, as shown by the chain line in FIG. , the cutting oil is supplied to each oil filler port through each oil supply pipe V provided in the supply source U, and furthermore, the cutting oil that has flowed into each oil filler port is supplied to the circumferential groove d, the injection hole q,
It is injected from the supply passage l and each outflow hole r1 to each cutting tip 0 located in the perforation part of the workpiece W to cool each cutting tip 0, and at the same time, the used cutting oil is transferred to the workpiece W. Together with chips generated during cutting, the inner cylinder k can be returned to the cutting oil supply source U through the main shaft i through a filter (not shown).

径や軸受りの直径において、回転数や同速度が制限され
る。However, in the above-mentioned drilling device, as is clear from FIG. 1, the main shaft i that abuts each one of the bearings fitted in the collector outer cylinder a and each of the oil seals f makes rolling motion or sliding contact. Because of this, there is a risk of heat generation and wear due to friction, so the number of revolutions and speed are limited by the diameter of the oil seal f and the diameter of the bearing.
即ち、この主軸iの回転数等の制限は切削工具の最適な
切削条件を与えろことが困難となり、これに追随して切
削工具の寿命や切削能率を低下させる原因になる。That is, limitations on the number of rotations of the spindle i, etc. make it difficult to provide the cutting tool with optimal cutting conditions, which in turn causes a reduction in the life of the cutting tool and the cutting efficiency.

る。On the other hand, as a means to solve this problem, if the diameter of the cutting tool used is limited according to the rotational characteristics of the cutting tool, if the range of drilling diameters is large, many types of drilling devices must be prepared in advance. Moreover, each time the cutting diameter differs, the cutting tool support, cutting oil piping, etc. must be replaced, which has the disadvantage of lowering the cutting efficiency.
