When the steel tube is used, its surface quality is good, and its surface is cross-mesh, which is more conducive to the storage of lubricating oil and the maintenance of the oil film. It has a high surface supporting ratio to some extent (the actual contact area between the hole and the shaft) with the ratio of the area of the joint between the two), it can withstand large loads and wear resistance, thereby increasing the service life of the product.
The steel tube has a low honing speed (one-tenth of the grinding speed), and the oil stone is in surface contact with the hole, so the average grinding pressure of each abrasive grain is small, so that the heat generated by the workpiece is small when honing. The surface of the workpiece has almost no thermal damage and metamorphic layers, and the deformation is small. The honed surface has almost no sand and extruded hard layers.
Wide range of processing of steel tube
The steel tube mainly processes various cylindrical holes, through holes, axial and radial interrupted holes, such as holes with radial holes or slots, key grooves, spline holes, blind holes, multi-step holes, and the like. In addition, with a special honing head, it is also possible to machine tapered holes, elliptical holes, etc., but because the boring head has a complicated structure, it is generally not used. The cylindrical honing tool can be used to honing the cylinder, but the margin of removal is much less than the margin of the inner honing. Honing can be used to process almost any material, especially diamond and cubic boron nitride abrasives, further expanding the application of honing and greatly improving the efficiency of honing.www.ht-tube.com
