Problems solved by technology

In the production process of heavy industrial ships and nuclear power heavy equipment, the welding and grinding process (before welding groove trimming and weld bead cleaning, welding seam interlayer cleaning, grinding and root cleaning, etc.), and the surface cleaning process of products and parts need to be used A large number of electric or pneumatic grinding wheel grinding equipment performs the corresponding process operations, requiring a lot of labor and consuming a lot of grinding wheels
[0003] In the grinding process, resin cymbal grinding wheels are mainly used, but the resin cymbal grinding wheels currently used are ordinary abrasives. During the working process, the grinding wheels have low strength, low efficiency, poor grinding performance, not durable, easy to fall off the abrasive, and easy to burn the workpiece. And there are a lot of dust and other problems in the grinding process
Seriously affect work progress, consume a lot of manpower and material resources, and are not environmentally friendly

Embodiment 1

[0030] a. Granulation of precursor abrasive: sieve and mix 60% cBN abrasive and 38% metal bond (65% Cu powder, 20% Sn powder, 10% Fe powder, 5% Ni powder) and mix evenly, add 2 % wetting agent is mixed evenly for agglomeration and nucleation, and then grows into massive particles after cold pressing. Crush and sieve the blocky particles to obtain the required sintered abrasive, put the abrasive into a microwave sintering furnace for rapid sintering and keep it at 720°C for 120 minutes.

[0031] b. Sieve and mix 51% of cBN abrasive, 15% aluminum-magnesium hydrotalcite filler, and 4% diamond filler, then add 30% silicone oil modified phenolic resin binder, sieve and mix evenly, and The mixing was carried out in a high speed mixer for 2 hours. Store the mixed abrasives under closed conditions at room temperature for 8 hours, then feed the mixed abrasives in an environment with a humidity of 50%. Coat a thin layer of liquid resin on the substrate, throw the abrasive evenly on th...

Abstract

The invention belongs to the field of super-hard grinding tools and relates to a making technology of a resin cBN cymbals-type grinding wheel. The making technology comprises the steps of design of acymbals-type grinding wheel base and a working layer (first accompanying diagram) and design of the structural size. The making technology comprises the two processes including the material grinding and pelleting process and the making process of the grinding wheel. The technology is suitable for industrial production, and the prepared grinding wheel is sharp, durable, environmentally friendly, safe, efficient and economical. The technical problems are solved that a common corundum cymbals-type grinding wheel in the prior art is poor in wear resistance, low in sharpness and not environmentallyfriendly or economical, and dust falls off severely.
