Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the cutter of cutting metal material, especially, relate to a cutter that reprocesses is carried out to the machined hole on the drilling machine.
[ background of the invention ]
At present, in the machine manufacturing industry, drilling machines comprise a vertical drilling machine, a bench drilling machine, a deep hole drilling machine, a radial drilling machine and the like. A drill is used to machine a hole in a workpiece. The most commonly used drill bits are twist drill, flat drill, deep hole drill, reamer, countersink, etc. The drill bit can drill through holes and blind holes and can expand and ream holes. Many times, through holes machined by twist drills have rough surfaces, particularly holes are easy to have burrs and bottom skins, and damage to human bodies or objects caused by scratches is possible. It must be machined again to remove it. The edge holes of the common flange are all designed with chamfers, so that burrs are avoided, and convenience is brought to screw installation. In the above-mentioned secondary processing step, a chamfer is generally formed by drilling the edge of the orifice with a hemp drill or by spot facing with a spot facing drill. Although the method for removing burrs and bottom skins by designing the chamfer is simple, the defects are obvious, and the defects are as follows: when the hemp-bit is used for processing chamfers, removing burrs and bottom skins at an orifice, only the cutting edge at the outer edge of the front end of the hemp-bit is locally cut and excessively worn, and the chisel edge at the middle structure of the front end of the hemp-bit does not participate in cutting and is not worn, so that the hemp-bit is often scrapped due to local damage. The cost of using the hemp drill is obviously higher. When the countersink drill bit is used for processing chamfers, removing burrs and bottom skins, the countersink drill bit is a special precision cutter, the price is high, and the use cost is obviously high.
[ summary of the invention ]
The utility model aims to provide a cutter of chamfer is beaten to high footpath ring flange limit hole. The chamfering machine is convenient and quick when chamfering the edge processing holes and removing burrs and bottom skins. And the cutting edge is durable, the sharpening is convenient, and the use cost is lower.
The technical scheme of the utility model as follows:
a cutter for chamfering the edge hole of a high-diameter flange comprises a cylindrical mounting handle 2 with a vertical axis, and is characterized in that: the bottom of the installation handle 2 is provided with a coaxial conical cutter body 1 with a downward conical tip, the conical angle of the cutter body 1 is 90 degrees, three inclined grooves with the same structure are uniformly distributed from the bottom surface of the cone to the conical angle tip part on the conical surface of the cutter body 1, and the inclined grooves simultaneously form the following structure:
cutting edge a101, chip groove b102, and rake angle c 103.
Cutting edge d105, chip groove e106, and edge rake angle f 107.
Cutting edge g109, flute h110, rake angle m 111.
Simultaneously has: the back edge clearance n104, the back edge clearance k108, and the back edge clearance s 112.
The following steps: the edge rake angle is defined by the angle between the intersection of the perpendicular to the cone axis from the cutting edge and the edge rake face. And is integrated with its corresponding flute.
The utility model is made of high-speed tool steel or hard alloy material. The sharpening is easy. The back angle of the blade is obtained by sharpening, a proper amount of back gap of the blade is generated, and the sharpness of the cutting edge is improved. The blade has high strength. Easy centering, difficult swing, difficult knife of jumping, it is durable, life is higher. The utility model has simple structure and low manufacturing cost.
The cylindrical mounting handle 2 is in a cylindrical shape with a circular cross section of the axis or in a regular hexagonal cross section of the axis. The bar 2 with the axis cross section in the shape of a regular hexagon cylinder has the best clamping effect.
The utility model has the advantages as follows: by adopting the technical scheme, the edge chamfering machine has the technical effects of convenience and rapidness in processing the chamfer at the edge hole and removing burrs and bottom skins, and is durable in cutting edge, convenient to sharpen and lower in use cost. The utility model has simple structure.
