Constant pressure and processing requirements for honing pipes

- May 01, 2019-

The honing pipe is mainly used in engineering, metallurgy, plastics, mining, road construction, textile and other industries. There are three main types of honing pipes, cold rolling, cold drawing and honing. The honing pipe is made of a high-precision grinding machine, which is used not only for round holes but also for hardening the tooth surface, which is also a polishing method. It can be used as a combined grinding tool that can be mounted on a floating fixture to make it self-adjusting. Therefore, the shape error of the hole can be reduced

The first stage is the shedding cutting stage. At the beginning, due to the rough wall of the hole, the contact area between the oil stone and the hole wall is small, the contact pressure is large, and the convex portion of the hole wall is quickly worn away. However, due to the high contact pressure on the surface of the oil stone and the wear of the oil-and-binder binder by the chips, the bonding strength between the abrasive particles and the binder is reduced. Therefore, some of the abrasive grains fall off under the action of the cutting pressure, and the surface of the oil stone is exposed. Abrasive grain, this is the oil stone self-sharp.


The second stage is the crushing and cutting stage. As the honing progresses, the surface of the hole becomes more and more light, the contact area with the oil stone becomes larger and larger, the contact pressure per unit area decreases, and the cutting efficiency decreases. At the same time, the cut chips are small and fine, and the wear of these chips on the adhesive is also small. Therefore, the oil stone abrasive grains are rarely peeled off, and the grinding is not performed by the new abrasive grains but by the abrasive grain tips. Therefore, the tip of the abrasive grain is very heavy, and the abrasive grain is easily broken and broken to form a new cutting edge.
