플라스틱 절삭용 절삭공구{Cutter for cutting to plastic}Cutting tool for cutting plastics {Cutter for cutting to plastic}

본 고안은 플라스틱 절삭용 절삭공구에 관한 것으로서, 더욱 상세하게는 금속의 자루에 고정되어진 초경합금의 절삭날 측부에 다이아몬드날을 부착함으로써 가공물의 절삭 작업시 절삭날에 발생되는 마모를 방지할 수 있으며 정밀한 절삭 작업을 수행할 수 있는 절삭공구에 관한 것이다.The present invention relates to a cutting tool for cutting plastics, and more particularly, by attaching a diamond blade to the cutting edge side of the cemented carbide fixed to the metal sack to prevent wear on the cutting edge during the cutting operation of the workpiece and precise The present invention relates to a cutting tool capable of performing a cutting operation.

일반적으로, 절삭공구는 선반, 셰이퍼, 보링머신과 같은 공작기계의 공구대에 장착되어 전·후,좌·우로 이동되면서 주축대의 척(chuck)에 고정된 가공물을 절삭할 수 있도록 되어 있다.In general, the cutting tool is mounted on a tool stand of a machine tool such as a lathe, a shaper, and a boring machine, so that the workpiece fixed to the chuck of the main shaft is moved while moving to the front, rear, left and right.

또한, 바이트(bite)라 불리우는 절삭공구는 초경합금으로 이루어진 절삭날을 자루(shank)에 고정시켜 사용하고 있다.In addition, a cutting tool called a bite is used by fixing a cutting blade made of cemented carbide to a shank.

그런데, 절삭날이 초경합금으로 이루어져 있다 하여도 절삭 작업을 반복해서 수행하다 보면 절삭날에 마모가 발생하게 되어 절삭공구나 절삭날을 교체해야 되는 문제점이 있으며 또한 절삭날의 마모로 인해 정밀한 가공을 수행할 수 없는 문제가 있다.However, even if the cutting edge is made of cemented carbide, if the cutting operation is repeatedly performed, there is a problem in that the cutting edge is abraded and the cutting tool or the cutting edge needs to be replaced. There is a problem that cannot be done.

따라서, 상기한 문제를 해결하기 위하여 본 고안은 초경합금의 절삭날 측면에 경도가 큰 다이아몬드날을 부착함으로써 절삭날의 마모를 방지할 수 있어 내마모성이 향상되게 되며 그로 인해 정밀한 절삭 작업을 수행할 수 있는 플라스틱 절삭용 절삭공구를 제공하고자 하는데 그 목적이 있다.Therefore, in order to solve the above problems, the present invention can prevent wear of the cutting edge by attaching a diamond blade having a high hardness to the cutting edge side of the cemented carbide, thereby improving wear resistance and thereby performing a precise cutting operation. It is an object of the present invention to provide a cutting tool for plastic cutting.

상기한 목적을 달성하기 위한 본 고안은 금속의 자루 끝단에 초경합금으로 이루어진 절삭날이 고정되어지고 상기 절삭날 측면에 절삭날과 동일한 형상으로 가공된 다이아몬드날이 부착되어진 것을 특징으로 하는 절삭공구를 제공함에 의해 달성된다.The present invention for achieving the above object is to provide a cutting tool, characterized in that the cutting blade made of cemented carbide is fixed to the end of the metal bag and the diamond blade machined in the same shape as the cutting edge is attached to the side of the cutting edge Is achieved by.

도 1 은 본 고안의 절삭공구를 나타낸 사시도,1 is a perspective view showing a cutting tool of the present invention,

도 2 는 본 고안의 정면예시도,2 is a front view of the present invention,

도 3 은 본 고안의 개략적인 사용상태예시도,3 is a schematic use state example of the present invention,

도 4 는 본 고안의 절삭공구로 가공물을 절삭하는 상태의 개략단면예시도이다.Figure 4 is a schematic cross-sectional view of a state of cutting the workpiece with the cutting tool of the present invention.

본 고안은 플라스틱과 같은 가공물(40)을 절삭하는 통상적인 절삭공구(10)에 있어서, 상기 절삭공구(10)는 금속의 자루(12)가 형성되어지고 이 자루(12) 끝단부에 초경합금으로 이루어진 절삭날(14)이 고정되어지며 상기 절삭날(14) 측면에 다이아몬드날(16)을 부착한 구성으로 되어진 것이다.The present invention is a conventional cutting tool 10 for cutting a workpiece 40, such as plastic, the cutting tool 10 is a metal bag 12 is formed and the end of the bag 12 with cemented carbide The cutting blade 14 is fixed and made of a diamond blade 16 attached to the cutting edge 14 side.

상기, 다이아몬드날(16)은 절삭날(14)과 동일한 형상으로 형성되어진 것이다.The diamond blade 16 is formed in the same shape as the cutting blade 14.

또한, 상기 절삭날(14)과 다이아몬드날(16)의 일면이 절삭 가공후 절삭공구(10)가 용이한 탈착을 이룰 수 있도록 경사각(18)이 형성되어진다.In addition, an inclination angle 18 is formed on one surface of the cutting edge 14 and the diamond blade 16 so that the cutting tool 10 can be easily detached after cutting.

첨부된 도면중 미설명 부호 (20)은 가공물(40)을 고정시키게 되는 척이고, (30)은 가공물(40)을 절삭시킬 수 있게 절삭공구(10)를 동작시키게 되는 CNC 공작기계이다.Reference numeral 20 in the accompanying drawings is a chuck to fix the workpiece 40, 30 is a CNC machine tool for operating the cutting tool 10 to cut the workpiece (40).

상기와 같이 본 고안은 첨부된 도면 도 3 에 나타낸 바와 같이, 절삭 가공하고자 하는 플라스틱 가공물(40)을 척(20)에 물려 고정시키고 상기 절삭공구(10)를 CNC 공작기계(30)에 고정시킨 상태에서 CNC 공작기계(30)를 가동시켜 상기 가공물(40)의 절삭 부위를 절삭공구(10)의 절삭날(14)로 절삭하게 된다.As described above, the present invention, as shown in the accompanying drawings, Figure 3, the plastic workpiece 40 to be cut is fixed to the chuck 20 and the cutting tool 10 is fixed to the CNC machine tool 30 In this state, the CNC machine tool 30 is operated to cut the cutting portion of the workpiece 40 with the cutting edge 14 of the cutting tool 10.

상기, 절삭날(14)로 가공물(40)을 절삭 작업시 작업횟수가 늘어남에 따라 절삭날(14)의 날끝에 마모가 발생하게 되어 절삭 작업이 정밀하게 이루어지지 않게 되는데 이때, 상기 절삭날(14)에 동일한 형상으로 부착되어진 경도가 큰 다이아몬드날(16)에 의해 가공물(40)을 절삭시 발생되어지는 절삭날(14)의 마모를 방지할 수 있게 된다.As the number of working times increases when cutting the workpiece 40 with the cutting edge 14, wear occurs at the cutting edge of the cutting edge 14 so that the cutting operation is not precisely performed. It is possible to prevent abrasion of the cutting edge 14 generated when cutting the workpiece 40 by the large diamond blade 16 attached in the same shape to 14).

따라서, 상기 절삭날(14)의 마모를 예방하게 되어 절삭공구(10)의 수명이 연장되며 또한 정밀한 절삭 작업을 수행할 수 있게 된다.Therefore, wear of the cutting edge 14 is prevented, thereby extending the life of the cutting tool 10 and performing precise cutting operations.

또한, 상기 가공물(40)을 절삭 가공후 가공물(40)로부터 절삭공구(10)가 이탈되어질 때 절삭날(14)과 다이아몬드날(16)의 일면이 경사지게 형성되어져 있어가공물(40)에서 절삭공구(10)가 걸리지 않고 원활하게 탈착되어진다.In addition, when the cutting tool 10 is detached from the workpiece 40 after cutting the workpiece 40, one surface of the cutting blade 14 and the diamond blade 16 is formed to be inclined, thereby cutting the workpiece 40 from the workpiece 40. (10) does not catch and can be detached smoothly.

본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

따라서, 본 고안은 플라스틱의 가공물을 절삭하게 되는 절삭공구의 절삭날 측면에 광물중에 경도가 가장 큰 다이아몬드날을 부착함으로써 절삭 작업시 절삭날 끝의 마모를 방지할 수 있어 절삭공구의 수명이 연장되게 됨과 동시에 정밀한 가공을 할 수 있으며 그로 인해 절삭 효율이 향상되게 되는 효과가 있다.Therefore, the present invention attaches the diamond blade having the largest hardness among the minerals to the cutting edge side of the cutting tool which cuts the workpiece of plastic, thereby preventing the wear of the cutting edge end during the cutting operation, thereby extending the life of the cutting tool. At the same time, precise machining can be performed, thereby improving cutting efficiency.
