Embodiment 1
[0033] This embodiment provides a method for preparing a CNC blade for heavy-duty machining, the steps of which are as follows:
[0034] S1. Take Co, TNC8, TiCN, (TI, W) C and WC respectively, wherein the mass fraction of Co is 8%, the mass fraction of TNC8 is 3.8%, and the mass fraction of TiCN is 0.8%, (TI, W) The mass fraction of C is 4.4%;
[0035] S2. The raw materials weighed in step S1 are added with 2% polyethylene glycol by weight of the raw materials, mixed evenly, and put into an inclined ball mill for ball milling for 15 hours;
[0036] S3 is granulated and pressed in the mixture obtained by ball milling in step S2, and then sintered. The sintering process is as follows: put the material into a sintering furnace with a hydrogen atmosphere, and heat up from 25°C to 180°C at a uniform speed for the first 30 minutes, and then heat up at a constant speed for 30 minutes. to 310°C, followed by 60min uniform heating to 370°C, then 270min uniform heating to 380°C, then 12...
Embodiment 2
[0039] This embodiment provides a method for preparing a CNC blade for heavy-duty machining, the steps of which are as follows:
[0040] S1. Take Co, TNC8, TiCN, (TI, W) C and WC respectively, wherein the mass fraction of Co is 8%, the mass fraction of TNC8 is 3.8%, and the mass fraction of TiCN is 0.8%, (TI, W) The mass fraction of C is 4.4%;
[0041] S2. The raw material weighed in step S1 is added with 2% polyethylene glycol by weight of the raw material, mixed evenly, put into an inclined ball mill for ball milling for 13 hours, and the ball-milled powder is evenly mixed;
[0042]S3 is granulated and pressed in the mixture obtained by ball milling in step S2, and then sintered. The sintering process is as follows: put the material into a sintering furnace with a hydrogen atmosphere, and heat up from 25°C to 180°C at a uniform speed for the first 30 minutes, and then heat up at a constant speed for 30 minutes. to 310°C, followed by 60min uniform heating to 370°C, then 270m...
Embodiment 3
[0045] This embodiment provides a method for preparing a CNC blade for heavy-duty machining, the steps of which are as follows:
[0046] S1. Take Co, TNC8, TiCN, (TI, W) C and WC respectively, wherein the mass fraction of Co is 8%, the mass fraction of TNC8 is 3.8%, and the mass fraction of TiCN is 0.8%, (TI, W) The mass fraction of C is 4.4%;
[0047] S2. The raw material weighed in step S1 is added to the polyethylene glycol of 2% by weight of the raw material, and after mixing evenly, put it into an inclined ball mill for ball milling for 11 hours, and mix the ball-milled powder evenly;
[0048] S3 is granulated and pressed in the mixture obtained by ball milling in step S2, and then sintered. The sintering process is as follows: put the material into a sintering furnace with a hydrogen atmosphere, and heat up from 25°C to 180°C at a uniform speed for the first 30 minutes, and then heat up at a constant speed for 30 minutes. to 310°C, followed by 60min uniform heating to 3...
