Cutting Process Of Honing


The cutting process of honing

The cutting process of honing is that the workpiece is fixed during honing. The honing head and the machine tool's spindle are floating and connected under a certain pressure through the relative movement of the honing head and the workpiece surface so that a very thin layer of metal is cut from the machining surface. During honing, the honing head has three movements, namely rotary motion, reciprocating motion and radial pressurizing motion perpendicular to the processing surface. The first two movements are the main movements of honing. Their synthesis makes the cutting trajectory of the abrasive grains on the stone on the surface of the hole intersect without reticulation, so it is easy to obtain a surface with a low surface coarseness. Radial pressurization is the feed motion of oilstone. The greater the pressure, the greater the feed.

Main characteristics of honing

Honing has the following main features 1. Honing is made of a softer material than the workpiece. During grinding, some abrasive particles are suspended between the workpiece and the grinding tool, and some abrasive particles are embedded in the surface layer of the grinding tool. The workpiece and the grinding tool are moved relative to each other, and the abrasive cuts a thin layer of metal on the workpiece surface mainly the bumps left by the previous process). 2. Manual grinding has a large workload and low productivity. The precision requirements of the are not high. Both metal and non-metal materials can be ground. 3. The grinding process of honing is not only processing metal with abrasive particles, but also chemical action. The abrasive mixture liquid forms an oxide layer on the surface of the workpiece, which makes it easy to be cut off by the abrasive, thereby greatly speeding up the grinding process. 4. The relative movement of the honing and the workpiece during grinding is more complicated. Therefore, each abrasive particle will not repeat its own trajectory on the workpiece surface, so it is possible to uniformly cut off the convex peaks on the workpiece surface. 5. Because honing is performed at low speed and low pressure, it is like that after grinding, the accuracy can reach IT6 or higher, and the surface roughness R. The value is less than 0.16 μm. But grinding cannot correct the position error of the hole, and the position accuracy of the hole can only be guaranteed by the previous process.
