Embodiment 1

[0031] Phenolic resin (type 2123), abrasive grains (alumina 3000#) and bamboo charcoal powder (12500#) were weighed respectively and stirred with a mixer for 10 minutes according to the mass ratio of 20%:20%:60%, and mixed evenly to make The mixture; the mixture is put into the mold, and the mold is closed. Put the mold into a hot press, heat it from room temperature to 120°C for 10 minutes, apply a pressure of 20 MPa, and heat it to 240°C for 42 minutes, and apply a pressure of 40 MPa. Take out the mold and let it cool to room temperature, open the mold and take out the blank grinding wheel. Put the formed semi-finished grinding wheel into a muffle furnace, heat it up to 900°C at an average heating rate of 10°C / min under normal pressure, keep it for 2 hours, and finally cool it with the furnace to obtain bamboo ceramic grinding wheel 1, and its properties are shown in Table 1 shown.

Embodiment 2

[0033] Phenolic resin (type 2123), abrasive grains (alumina 3000#), and bamboo charcoal powder (12500#) were weighed respectively and stirred with a mixer for 10 minutes according to the mass ratio of 25%: 20%: 55%, and mixed evenly. The mixture; the mixture is put into the mold, and the mold is closed. Put the mold into a hot press, heat it from room temperature to 120°C for 20 minutes, apply a pressure of 10 MPa, and heat it to 240°C for 40 minutes, and apply a pressure of 42 MPa. Take out the mold and let it cool to room temperature, open the mold and take out the blank grinding wheel. Put the formed semi-finished grinding wheel into a muffle furnace, heat it to 900°C at an average heating rate of 10°C / min under normal pressure, keep it for 2 hours, and finally cool it with the furnace. Its properties are shown in Table 1.

Embodiment 3

[0035] Phenolic resin (type 2123), abrasive grains (alumina 3000#), and bamboo charcoal powder (12500#) were weighed respectively and stirred with a mixer for 10 minutes according to the mass ratio of 30%:20%:50%, and mixed evenly to make The mixture; the mixture is put into the mold, and the mold is closed. Put the mold into a hot press, heat it from room temperature to 120°C for 10 minutes, apply a pressure of 20 MPa, and heat it to 240°C for 42 minutes, and apply a pressure of 40 MPa. Take out the mold and let it cool to room temperature, open the mold and take out the blank grinding wheel. Put the formed semi-finished grinding wheel into a muffle furnace, heat it up to 900°C at an average heating rate of 10°C / min under normal pressure, keep it for 2 hours, and finally cool it with the furnace to get bamboo ceramic grinding wheel 3, its properties are shown in Table 1 shown.

Abstract

The invention discloses a bamboo ceramic grinding wheel, a preparation method and application thereof. The bamboo ceramic grinding wheel is prepared by obtaining a blank grinding wheel by the following raw materials through mixing, mold feeding, hot press molding and stripping, and roasting the blank grinding wheel; and the raw materials comprise 20 to 30 percent of phenolic resin, 20 to 30 percent of abrasive particles, and 40 to 60 percent of bamboo charcoal powder according to the mass ratio. The bamboo ceramic grinding wheel is used for ELID grinding, and can ensure that the processed surface has better quality. Compared with the prior art, the invention introduces bamboo charcoal into the raw materials; the bamboo charcoal has rich resources and is environment-friendly; and the bamboo charcoal contributes to the grinding due to the fact that the bamboo charcoal has a microporous structure. The grinding wheel has simple preparation; and the bamboo ceramic grinding wheel ensures that processed surfaces have extremely high surface integrity and cleanliness, has high processing efficiency, can process hard-to-cut materials such as cohesive materials, soft materials and the like, provides a new way for grinding processing, and is environment-friendly and pollution-free.

Description

technical field [0001] The invention belongs to the field of precision and ultra-precision machining, and relates to a bamboo ceramic grinding wheel and its preparation method and application, especially the application in ELID surface grinding processing. Background technique [0002] Electrolysis In-process Dressing (ELID) grinding can realize high-efficiency and ultra-precision surface processing of hard and brittle materials, and has become one of the main means and research directions of ultra-precision grinding in the future. With the continuous development of new materials and precision devices, the requirements for the quality of processed surfaces are getting higher and higher. [0003] Existing ELID grinding mainly uses cast iron-based bonded diamond or CBN grinding wheels, relying on the cast iron bond material to form an oxide film on the surface of the grinding wheel through electrolysis, so that the diamond abrasive grains are exposed on the surface of the grin...
