本考案は精密内径穴加工に使用するオイルホー
ル付き電着リーマ工具に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electroplated reamer tool with an oil hole used for precision internal hole machining.

うにしたものが知られている。(Conventional technology) Conventionally used electrodeposition reamers include:
A type without an oil hole for supplying machining fluid as shown in Figure 3, and a type with a structure for supplying machining fluid as shown in Figure 4 have an oil hole in the axial direction and the side surface of the electrodeposition part. It is known to have a slotted groove for supplying machining fluid in the axial direction so that the hole and the groove communicate with each other.

た。(Problem to be solved by the invention) However, in the above-mentioned reamer tool, machining fluid such as oil is not sufficiently supplied to the machining point, and as a result, clogging with chips tends to occur between the electrodeposited abrasive grains, which causes the machining surface to become clogged. This caused peeling and welding of chips, making it impossible to improve machining accuracy.

ド部である。 In particular, the reamer tool 11 shown in Figure 3 does not have an oil hole, so it is externally lubricated, and as a result, it is naturally difficult to supply machining fluid to the machining point. Even if the reamer tool 12 has a reamer tool 13, as shown in FIG.
As mentioned above, the oil hole 13 and the machining fluid supply groove 1
Since hole 5 is in communication with hole 1 in the longitudinal direction,
The machining fluid escaped to areas other than 6, and it was difficult to say that the machining fluid was being sufficiently supplied to the machining points. In the figure, 17 is a guide portion of the reamer tool 12.

れたものである。 In view of this, the present invention provides an electroplated reamer tool with an oil hole that is provided with an oil hole for supplying machining fluid near the machining point and has a shape that prevents machining fluid from escaping to areas other than the machining point. This was done with the aim of suppressing clogging of the electrodeposited parts with cutting chips and increasing machining accuracy and machining efficiency.

とする。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a shaft material having a circular cross-section, which extends over a predetermined length of the outer circumferential surface of the shaft material to form a machined part, so that the outer circumferential surface is equally divided. In an electroplated reamer tool that has a long notch in the direction and electrodeposit processing abrasive grains on the remaining outer peripheral surface, an oil supply hole is drilled in the center of the shaft material, and the oil supply hole is formed in the center of the shaft material. The present invention is characterized in that an oil hole is formed from the hole at the outer surface of the electrodeposited abrasive grains in the tip processing portion of the electrodeposited reamer tool.

に逃げないようにしてある。 The electroplated reamer tool with an oil hole according to the present invention is long in the axial direction so as to equally divide the outer circumferential surface 2 of the shaft 1 having a circular cross section over a predetermined length that forms a processing part. In an electroplated reamer tool in which notches 3 are provided and processing abrasive grains are electrodeposited on the remaining outer peripheral surface 2, an oil supply hole 5 is bored in the center of the shaft 1, and the oil supply hole 5 is formed in the center of the shaft 1. An oil hole 6 is drilled in a direction that opens from the hole 5 toward the electrodeposited reamer tool tip 4, and opens at the electrodeposited surface of the processing abrasive to prevent clogging with cutting chips. This is what I did. As a result, a plurality of oil holes 6 (eight in the embodiment) for supplying machining fluid such as oil are provided near the machining point of the workpiece, that is, approximately at the center of the taper length of the tip 4, in a portion where there is no notch 3. It is designed to prevent the machining fluid from escaping to areas other than the machining points.

ール６から供給される加工液は電着砥粒間に付着
する切粉を押し流しながら外部へ流れる。 Next, the effect will be explained. In reaming, the parts that act on machining the workpiece are the shaft 1 and the tip 4 of the taper, and the part that receives the largest machining load is the tip 4 of the taper. Since this tip 4 is responsible for most of the inner diameter machining, it is most likely to be clogged with chips. Therefore, the machining fluid supplied from the oil hole 6 provided in this portion flows to the outside while washing away the chips adhering between the electrodeposited abrasive grains.
また、オイルホール６は切り欠き３とはつなが
つていないため、常に一定の加工液圧を加工点に
加えることができる。 In addition, since the oil hole 6 is not connected to the notch 3, a constant machining fluid pressure can always be applied to the machining point.
そして先端４を除く軸１の外周面２への加工液
供給は、外部からの給油により行われ、外周面２

供給される。 The machining fluid is supplied to the outer circumferential surface 2 of the shaft 1 except for the tip 4 by external oil supply.
It is supplied to the entire processing section through eight notches 3 provided in the.

めることが難しいが、オイルホールを設けること
により加工条件を高めることがてきる。 Figure 2 shows a comparison between the reamer tool of the present invention and a conventional reamer tool without an oil hole, using a graph showing the relationship between machining length and finished surface roughness. Since clogging by chips is reduced, the machining length at which the finished surface roughness begins to deteriorate is longer. In other words, with a tool without an oil hole, it is difficult to improve machining conditions due to clogging with chips, but by providing an oil hole, machining conditions can be improved.

うになつた。 In addition, it has been difficult to perform electroplated reaming on workpiece materials that produce long chips, such as Al and Ni alloys, but by providing oil holes, the machining conditions are restricted. However, it is now possible to process it.

Although it has a simple structure, it has excellent effects.
