ものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a diamond tool used for various precision finishing, sawing, mirror finishing, etc., in which the cutting edge at the tip is made of diamond. It relates to a method with a blade.

ヤモンドバイトと、その製造方法」に関する特許出願
を、本特許出願と同時に行った。The applicant of the present invention wrote, `` A metal sintered body is fixed to the upper surface side of the tip of the shank, and both sides are formed in a tapered shape and the rake face of the diamond chip having a trapezoidal cross section is almost left. A patent application for "a diamond tool having a structure entirely embedded in the metal sintered body and a manufacturing method thereof" was filed at the same time as the present patent application.
この新規なダイヤモンドバイト（以下、単にバイトと

端部に固着されたチップの刃付面を押付けて行ってい
る。One of the features of this new diamond tool (hereinafter simply referred to as a tool) is that it can be processed with a blade while a diamond tip (hereinafter simply referred to as a chip) is fixed to a shank. The cutting process of the cutting tool is performed by holding the shank of the cutting tool with a jig, and attaching the cutting surface of the tip fixed to the tip of the shank to a cast iron disk called skiff coated with diamond fine particles. It is pressing.

接触抵抗が大きい。加工が進行して、チップの刃付面が
鏡面に近づくと、上記スカイフとの接触抵抗が増大する
ために、加工中においてチッピング（小さなびびり）が
生じる。このチッピングが生じると、切れ味の良い鋭い
刃先は得られない。According to this method, since the entire bladed surface of the chip is pressed all the time to the skiff, the contact resistance between the skif and the chip is large. As the processing proceeds and the bladed surface of the tip approaches the mirror surface, chipping (small chatter) occurs during the processing because the contact resistance with the skiff increases. When this chipping occurs, a sharp and sharp cutting edge cannot be obtained.
本発明は、シャンクに固着されたチップをスカイフに
押付けて刃付加工を行うに際して、スカイフとチップと
の接触面積を小さくして、鋭い刃先を得ることを課題と
している。SUMMARY OF THE INVENTION It is an object of the present invention to reduce the contact area between a skiff and a tip and obtain a sharp cutting edge when the tip fixed to a shank is pressed against a skiff to perform cutting with a blade.
この課題を解決するために本発明の採用した手段は、
シャンクにチップが固着された状態で刃付加工を行うに
際して、前記チップの刃付面全体を目的の角度よりもや
や大きな角度で粗面状に加工し、その後に刃先部のみを
目的とする角度で鏡面状に加工して、刃付面を二面加工
することである。Means adopted by the present invention to solve this problem are:
When performing the cutting with the tip in a state where the tip is fixed to the shank, the entire cutting surface of the tip is processed into a rough surface at an angle slightly larger than the target angle, and thereafter, only the cutting edge portion has the target angle. To form a mirror-like surface, and to process the two surfaces with blades.
刃付面を二段階に分けて刃付加工し、後の段階では、
チップの刃先部のみをスカイフに押付けて加工するの
で、チップ全体を終始スカイフに押付けて刃付加工を行
う従来方法に比較して、チップとスカイフとの接触面積

のため、鏡面状態に近づいてもチップのびびりはなくな
って、鋭い刃先が得られる。The bladed surface is divided into two stages and processed with a blade.
Since only the tip of the tip is pressed against the skif, the contact area between the tip and the skif is reduced, and the contact resistance is reduced, compared to the conventional method in which the entire tip is pressed against the skif and the cutting process is performed. It becomes significantly smaller. For this reason, even if the mirror surface state is approached, the chip does not chatter and a sharp cutting edge is obtained.
以下、実施例を挙げて、本発明を更に詳細に説明す

利点がある。1 to 3, a metal sinter M is fixed to the upper surface side of the tip of the shank S by brazing, and the rake face 1 of the chip C is attached to the metal sinter M.
Almost the whole is buried except for. Chip C is
As shown in FIGS. 4 to 6, the width is gradually increased from the front end to the rear end, and both side surfaces 2 are formed in a tapered shape, except for the flank 3 at the front end. The cross section is trapezoidal. For this reason, the chip C is embedded so as to be held by the metal sintered body M, and the fixing strength of the chip C itself is increased by the shape of the chip C itself. Since the cutting tool B can be machined with the tip C in a state where the cutting tool C is fixed to the shank S, there is an advantage that each cutting tool angle can be accurately processed as set.

磨して刃付加工を行えるので、鋭い刃先が得られる。Then, in order to perform the cutting process on the rake face 1 of the chip C, as shown in FIG. 7, first, almost the entire rake face 1 (A) is pressed against the rotating skiff, and as shown in FIG. The rake face of the rake face 1 (A 0 ) is pressed against the rotating skiff, and the rake face is machined into a mirror surface at the desired angle. Do it. In this way, when machining the cutting edge portion (A 0 ) of the rake face 1, since the contact area with the skiff is small, the resistance is also small, and the cutting edge portion (A 0 ) approaches a mirror surface. However, it can be processed without causing chipping while keeping in close contact with the skiff. Similarly, when the flank 3 is to be machined with a blade, the entire surface (D) is roughened at an angle slightly larger than the intended purpose, and then only the blade edge (D 0 ) is rotated. It is pressed against the skiff, and processed into a mirror surface at the desired angle. When the bladed surface is machined on two sides in this way, a sharpened blade edge can be obtained because only the blade edge portion of the bladed surface is intensively polished and the bladed process is performed without causing chipping.
