The precision of the honing pipe processing process is high, especially some small and medium-sized through holes, the cylindricity can reach 0.001mm or less, and the roundness of some large holes can reach 0.005mm to some extent, if there is no ring It is also possible to have a straightness of 0.01 mm/1 m or less in a groove or a radial hole.
The surface quality of the honing pipe is good.
The surface of the honing pipe is cross-web, which is more conducive to the storage of the lubricating oil and the maintenance of the oil film during the operation. It has a relatively high surface support rate during processing, and thus can withstand large loads and wear resistance. , thereby increasing the life of the product.
The honing speed is low, and the oil stone and the hole are in surface contact, so the average grinding pressure of each abrasive grain is small, so that the heat generated by the workpiece is small when honing, and the surface of the workpiece has almost no heat damage and the metamorphic layer and deformation are small. The honing tube has almost no sand and extruded hard layers on the machined surface.
Wide range of honing tubes
The honing pipe processing is mainly applied to the through hole, the radial direction and the axially interrupted hole in the process of operation. In addition, the special honing head can also process the tapered hole, the elliptical hole, etc., and the cylindrical honing tool can honing the cylinder. Body, but the margin of its removal is much smaller than the margin of the inner circle. The 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.
Honing tube processing with less cutting allowance
In order to achieve the precision required by the drawings, the honing pipe processing takes the least amount of machining method in all the processing methods in the process of making the honing tool, and the honing tool uses the workpiece as a guide to cut off the excess workpiece. The remaining amount reaches the precision required for the workpiece. When honing, the honing tool first picks up the place where the allowance is the largest, and then gradually picks up the place where the least amount of allowance is needed.www.ht-tube.com
