て提案されている方法および装置がある。(Prior art) Surface flaws must be removed from high-grade rods and wire rods such as spring steel, but conventionally this has been done manually using a grinder or by cutting the entire circumference and length.
No. 53, JP-A-56-114613, JP-A-58-2
There are methods and devices proposed in various publications such as No. 4201 and Japanese Unexamined Patent Publication No. 59-142054.
（発明が解決しようとする課題）
人手によるグラインダー手入れは、棒線材の４周全体を
目視して探傷するので作業性が極めて低（、人件費が大
巾にアップする、疵見落しが発生するなどの問題がある
。また全周全長に亘る切削除去では疵見落しの心配はな
いものの、疵のない正常部分まで切削除去するので歩留
を大巾に低下させ、製造コストが高（なる欠点がある。(Problem to be solved by the invention) Manual maintenance of the grinder requires visual inspection of the entire four circumferences of the rod and wire material, resulting in extremely low work efficiency (significant increase in labor costs and oversight of defects) Although there is no need to worry about overlooking defects when cutting and removing the entire length of the entire circumference, cutting and removing even normal parts with no defects greatly reduces the yield and increases manufacturing costs. There is.
一方、棒線材の表面疵は断続的で発生部位も一定でなく
、同−周に２箇所以上の表面疵が発生（以下このような
疵を部分疵と呼ぶ）することもしばしばである。On the other hand, surface flaws on rods and wires are intermittent and the locations where they occur are not constant, and surface flaws often occur at two or more locations on the same circumference (hereinafter such flaws are referred to as partial flaws).
従って、全周全長に亘って表面疵のない良好な棒線材を
製造するには部分疵を探傷器Ｖｔにより検出し、該検出
信号を受けて、被削体のどこに部分疵があっても、ある
いは全周の複数箇所に部分疵があっても切削除去できる
部分疵取装置が必要である。Therefore, in order to manufacture good wire rods without surface flaws over the entire circumference and entire length, partial flaws are detected by a flaw detector Vt, and upon receiving the detection signal, no matter where on the workpiece there is a partial flaw, Alternatively, there is a need for a partial flaw removing device that can remove partial flaws even if they are present at multiple locations around the entire circumference.

するため、ビビリ振動による縞状切削面が発生する。Looking at the above-mentioned Japanese Patent Publication No. 59-50453, which seems to be the most promising means for solving these problems, the following drawbacks can be found. That is, (1) Since the rigidity of the entire structure including the tool holder is insufficient, a striped cutting surface occurs due to chatter vibration.
（２）部分疵取ユニットは被削体の軸方向にずらされて
単独に配置されているため、設備スペースを広く必要と
し設備費も高価なものとなる。(2) Since the partial flaw removal unit is individually arranged and shifted in the axial direction of the workpiece, a large equipment space is required and the equipment cost is high.
（３）部分疵取装置機長が長いため、サプライスタンド
でのコイル捲戻し不良等により線材コイル捻れ発生時疵
取残しの原因となる。(3) Since the machine length of the partial flaw removing device is long, defects may be left behind when wire rod coils are twisted due to poor coil unwinding at the supply stand, etc.

), the cutting range angle of each cutting tool is 110.
The cutting range angle for eaves the first side of the workpiece 2 (A) is as small as 110 degrees. It is stable and can be accurately taken over without escaping. However, as shown in Fig. 6 (5), when the third side is shielded with the cutting tool lOD after the second side is shielded with the adjacent cutting tool (b), the wire holder is cut in the gap between the workpiece 2 and the guide 8. The depth of cut is shallow due to the relief to the cutting surface side.The second stage setting value is to set the depth of cut that corrects this relief, and it should be left for all partial defects removal. The overlapping angle of adjacent cutting tools is 10 degrees, and there are no defects left between the cutting tools.
ここで、上述の切削バイトの切削範囲角度は９０度から
１２０度内にすることがもつともｉ＆適である。Here, it is preferable that the cutting range angle of the above-mentioned cutting tool be within 90 degrees to 120 degrees.
それは９０度未満では切込み角度が鋭角となり、この部
分が表面欠陥となり易く、又１２０度を超すと隣接に疵
がない場合、無駄な部分をも切削することになり歩留上
、不利となるためである。なお、この角度範囲外にして
も切削上は全く問題はない。This is because if the cutting angle is less than 90 degrees, the cutting angle becomes acute and this part is likely to become a surface defect, and if it exceeds 120 degrees, if there are no adjacent flaws, unnecessary parts will also be cut, which is disadvantageous in terms of yield. It is. Note that there is no problem in cutting even if the angle is outside this range.

Even when eaves the second surface in surface eaves removal (eaves 6A and 6B or 6C and 6D), the workpiece 2 does not escape and can be accurately partially removed, so no defects are left behind (0 (4) ) In this example, there are four sets of partial defect removal units, but since they have the same basic structure, n units are arranged in series, and the cutting direction of each unit is shifted by an angle of 36 Q/n degrees to cover the entire circumference of the workpiece. Scratches can be cut out and manufacturing costs can be reduced by standardizing design drawings and device structures.
