Self-cooling vertical stone machining tool and manufacturing method thereof

Abstract

The invention provides a self-cooling vertical stone machining tool and a manufacturing method thereof. The self-cooling vertical stone machining tool comprises a tool body and a tool handle, whereina main blade and an auxiliary blade are arranged on the tool body, a main cooling hole is formed in the tool handle, the main cooling holes are blind holes which extend into the tool body in depth, aplurality of auxiliary cooling holes extending outwards along the radial direction of the tool handle are formed in the inner wall of the main cooling hole; the manufacturing method comprises the following steps of preparing a tool blank through a sintering or chemical vapor deposition method, milling a spiral groove by using a milling machine, a main cutting edge and an auxiliary cutting edge aremachined through grinding and grinding, and a main cooling hole and an auxiliary cooling hole are machined through an electric spark punching machine. According to the adoption of the technical scheme, the polycrystalline diamond material has high hardness, the cutting performance of the tool is greatly improved, the cooling liquid flows through the main cooling hole and the auxiliary cooling hole to cool the tool, the situation that the local area of the tool is excessively heated is avoided, the tool is protected, the service life of the tool is prolonged, the structural strength of the tool is high, and the workpiece machining quality is improved.

Description

technical field [0001] The invention belongs to the technical field of stone processing equipment, and in particular relates to a self-cooling vertical stone processing tool and a manufacturing method thereof. Background technique [0002] With the development of the stone processing industry, the demand for cutting tools used in the stone processing process is also increasing. In the current market, a variety of cutting tools for cutting stone are provided. At present, the most widely used The tool used for cutting stone is mainly a cutter wheel, which is generally made of solid carbide. It rolls on the stone and uses the cutting edge with a sharp edge to cut the stone. The longest life of cutting stone in industry is about 150,000 meters. , generally 5 to 60,000 meters. However, the life of this type of cutter wheel still fails to meet the requirements well. There is also a type of vertical cutter in the prior art. This kind of cutter cannot be fed along the axial direct...

However, the life of this type of cutter wheel still fails to meet the requirements well

There is also a type of vertical cutter in the prior art. This kind of cutter cannot be fed along the axial direction of the cutter during work. The outer peripheral surface of the vertical cutter is generally provided with a main cutting edge, and the end surface is provided with a secondary cutting edge. Vertical cutting tools are widely used. When vertical cutting tools are used for a long time, a large amount of cutting heat will be generated due to the relative movement between them and the workpiece. Reduce the processing quality of the workpiece. In the prior art, the corresponding cooling pipe is generally installed on the processing machine tool, and the cooling liquid is transported to the gap between the vertical tool and the workpiece through the cooling pipe. With this cooling method, due to the direction of the cooling pipe It can
