Embodiment 1

[0042] Embodiment 1: A kind of method for sharpening a diamond cutter head, comprising the following steps: clamping a cuboid diamond cutter head formed by sintering on a fixture, fixing the fixture on the workbench of a water jet machine, and using a high-pressure water jet to The surface of the diamond cutter head needs to be processed for sharpening. The pressure of the high-pressure water jet is 55,000 Psi. The outer diameter of the sand knife tube is 7.14 mm, the inner diameter is 1.02 mm, and the length is 76.2 mm. The cutting speed of the high-pressure water jet is 2mm / min , the distance between the water outlet of the high-pressure water jet and the cutting plane of the diamond cutter head is 10mm, the angle between the jet direction of the high-pressure water jet and the cutting plane of the diamond cutter head is a right angle, and the high-pressure water jet contains abrasives, which are made of 80-mesh pomegranate The volume ratio of abrasive to water is 10:100, so ...

Embodiment 2

[0043] Embodiment 2: A method for sharpening a diamond cutter head, comprising the following steps: after welding the sintered rectangular parallelepiped diamond cutter head on the surface of the carcass, and then clamping it on the fixture, fixing the fixture on the working surface of the water jet machine On the stage, high-pressure water jets are used to sharpen the surface of the diamond cutter head to be processed. The pressure of the high-pressure water jets is 75,000 Psi. The cutting speed of the jet is 4mm / min, the distance between the outlet of the high-pressure water jet and the cutting plane of the diamond cutter head is 10mm, and the angle between the jet direction of the high-pressure water jet and the cutting plane of the diamond cutter head is a right angle. Contains abrasives, 80-mesh garnet is used for abrasives, and the volume ratio of abrasives to water is 10:100, so that the diamond particles are exposed to form cutting edges.

Embodiment 3

[0044] Embodiment 3: A kind of method for sharpening a diamond cutter head, comprising the following steps: clamping a cuboid diamond cutter head formed by sintering on a fixture, fixing the fixture on the workbench of a water jet machine, and using a high-pressure water jet to The surface of the diamond cutter head needs to be processed for sharpening. The pressure of the high-pressure water jet is 55,000 Psi. The outer diameter of the sand knife tube is 7.14 mm, the inner diameter is 1.02 mm, and the length is 76.2 mm. The cutting speed of the high-pressure water jet is 19mm / min. , the distance between the water outlet of the high-pressure water jet and the cutting plane of the diamond cutter head is 10mm, the angle between the jet direction of the high-pressure water jet and the cutting plane of the diamond cutter head is a right angle, and the high-pressure water jet contains abrasives, which are made of 80-mesh pomegranate The volume ratio of abrasive to water is 10:100, s...

Abstract

The invention discloses a method for sharpening a diamond cutter head, and relates to the technical field of abrasive processing. The key points of the technology are: use high-pressure water jet to sharpen the surface of the diamond cutter head to be processed, so that the diamond particles are exposed to form a cutting edge. The present invention uses a high-speed water jet to wash away a part of the carcass, so that the diamond particles are exposed. Since the water jet does not damage the diamond particles, it will not cause the loss of the diamond particles, and can be suitable for the processing of diamond cutter heads of different shapes; While processing, the high-pressure water jet can wash away the burrs on the cutting edge surface, reduce the subsequent grinding burr process, and improve production efficiency; the heat generated by the collision between the diamond cutter head and the high-pressure water jet will be immediately taken away by the high-speed water jet, And no harmful substances are produced, the material has no thermal effect, and there is no burning phenomenon of sanding, which improves the processing accuracy.

Description

technical field [0001] The invention relates to the technical field of abrasive processing, more specifically, it relates to a method for sharpening a diamond cutter head. Background technique [0002] Most of the diamond cutter heads are installed in the mold, pressed and sintered, and each saw blade requires dozens or even hundreds of cutter heads. Therefore, the size of the cutter heads of each saw blade cannot be exactly the same. In particular, the difference in the size and height of the cutter head will directly affect the radial runout of the saw blade, which will affect the cutting quality and efficiency of the saw blade, so sharpening is required. [0003] In the Chinese invention patent with the publication number CN107322093A, a method for cutting the edge and cleaning the root of a diamond saw blade is disclosed, which includes the following process steps: turn on the power, and set the relevant parameters of the saw blade through the control panel, including th...
