s3, inserting the shaft of the bar II into the hole of the bar I;
and S4, grinding the other end of the bar material II by using a grinding machine to form a tool nose.
Further, the bar in step S1-1 is cut out by cutting out an elongated stainless steel strip; the bar in step S1-2 is cut out from an elongated tungsten steel bar.
Preferably, after step S1-1, the bar material is cleaned, which may be cleaned by a brush, a high pressure air jet, or a rag; after step S1-2, the second bar is cleaned, which may be cleaned by a brush, a high pressure air jet, or a rag.
Further, after step S3, cooling is performed so that the expanded hole shrinks to hold the collar tightly, and then the tool shank is fixedly mounted on the jig, and the jig is placed in the grinding machine, and then the process proceeds to step S4.
The equipment is used for producing the nested cutter and comprises a cutting device, a heating device, a jig and a grinding machine; the cutting device is used for cutting to obtain a first bar material or/and a second bar material; the heating device is used for heating the hole or/and the shaft; the jig is used for fixing the cutter handle.
The grinding machine is a grinding machine with an electromagnet attraction device, and the jig is made of a metal material and can be attracted by the electromagnet attraction device.
Because the handle is made of stainless steel, the material cost is lower, the manufacture is easier, fewer worn processing tools are needed, the efficiency is higher, and the processing time is shorter. The tool bit is made of tungsten steel, so that the hardness also reaches the hardness in the prior art, and the shaft is arranged on the tool bit, so that the tool bit is easier to process and only needs to cut a bar. No matter the stainless steel bar or the tungsten steel bar is directly cut by the round bar, the steps do not need to be processed, so that the manufacturing is simpler, and the cost is lower. The machining of the holes is made in stainless steel bars and is therefore very efficient. Tungsten steel bars cannot be used as holes because they are very hard and are very difficult to machine in small holes, which makes them more difficult to machine to achieve higher precision, and holes that are too small are formed without smaller drill bits.
In the invention: the cutter has simple structure, low cost, long service life and high precision; the production method has the advantages of simple method, short flow, capability of improving the production efficiency and relatively stable production stability; the equipment has the advantages of simple structure and convenient operation.
