Embodiment 1
[0025] The carcass raw materials are: 41 parts of pure Fe powder, 30 parts of pure Cu powder, 7 parts of pure Zn powder, 8 parts of pure Co powder, 8 parts of pure Ni powder, and 6 parts of pure Mn powder.
[0026] Such as figure 1 As shown, the sintered diamond milling cutter with strong wrapping ability prepared by the present invention includes a working end composed of a base body 1 and a diamond sintered body 2, and a nozzle 3 is provided on the diamond sintered body 2, and the diamond sintered body 2. It is composed of sintered diamond milling cutter matrix and diamond. Among them, the diamond particle size is 35 / 40, the concentration is 48%, the working layer height of the working end is 5.7mm, the wall thickness is 2.3mm, and the milling cutter diameter is 22mm , The number of nozzles is 8, the nozzle is round hole shape, and the diameter of the nozzle is 1.9mm.
[0027] The preparation method of the milling cutter includes: firstly, selecting a suitable metal substra...
Embodiment 2
[0030] The carcass raw materials are: 47 parts of pure Fe powder, 31 parts of pure Cu powder, 10 parts of pure Zn powder, 5 parts of pure Co powder, 4 parts of pure Ni powder, and 3 parts of pure Mn powder.
[0031] The process parameters of the milling cutter are: the height of the working layer is 6.3mm, the wall thickness is 2.7mm, the diameter of the milling cutter is 25mm, the number of nozzles is 8, the nozzle is in the shape of a round hole, the diameter of the nozzle is 2.3mm, and the diamond particle size is 50 / 60 , the diamond concentration is 56%.
[0032] The production method includes: firstly select a suitable metal substrate, and process it into the required shape and size, and prepare and place the matrix according to the working layer height, wall thickness, diameter and nozzle of the sintered diamond milling cutter with strong wrapping ability to be prepared. secondly, prepare the carcass, mix the diamond with the carcass and put it into a graphite mold, hot ...
Embodiment 3
[0035] Design 6 groups of parallel experiments, the basic steps are the same as in Example 1, the difference is only the raw material components of the carcass, which are respectively:
