The Honed tube has high processing precision when it is used, and in particular, some small and medium-sized through holes have a cylindricity of up to 0.001 mm. Honing is more accurate than grinding because the bearings that support the grinding wheel are located outside the bore. Honing generally only improves the shape accuracy of the workpiece, and it is necessary to take some necessary measures to improve the positional accuracy of the part. If the panel is used to improve the perpendicularity of the end face of the part and the axis (the panel is mounted on the stroke bracket, the adjustment is made perpendicular to the rotating spindle, and the part is machined on the panel).
The surface quality of the Honed tube is good, and the surface is cross-mesh, which is beneficial to the storage of the lubricating oil and the maintenance of the oil film. It has a high surface support ratio (the actual contact area between the hole and the shaft and the ratio of the area of the joint between the two), so that it can withstand large loads and wear resistance, thereby improving the service life of the product. The honing speed is low (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, and the surface of the workpiece is almost No thermal damage and metamorphic layer, small deformation. The honed surface has almost no sand and extruded hard layers.
The cutting of the Honed tube is also relatively reduced. If the diameter is greater than 50 mm, it is best to use mechanical machining to cut, to ensure that the cutting surface of the pipe is flat, and there are no defects such as burrs, scales and slag.www.ht-tube.com
