What Is Honed Tube

1. Size range of honing tube
Honed tube is honed by honing machine through the honing oil stone bar to carry out, and the surface to be honed for finishing grinding, to achieve the desired processing effect. Therefore, the honed tube obtained by honing machine honing, its bore diameter, in general, is 5 to 500 millimeters in this range.

2. the difference between precision rolled tube, cold drawn tube and honed tube The processing equipment of precision rolled tube is "steel tube cold rolling mill", the processing equipment of cold drawn tube is "steel tube cold drawing machine", and honed tube is honed on the basis of cold drawn tube or precision rolled tube and then (on the honing machine). From the accuracy and surface, the surface and accuracy of the best is honed tube, followed by precision rolled tube, and finally cold drawn tube, (if you add a hot rolled tube, then the surface and size of the worst is considered to be hot rolled tube) There are too many ways to categorize the steel pipe can be classified according to the use, according to the processing method, material composition and so on.

3. honed tube surface roughness is how much?
Honed tube, is a seamless steel tube after quilting. Honing is a mechanical process, through the honing head on the cold-drawn tube bore reciprocating high-speed grinding process processing, so that the bore to achieve our required tolerance size and surface roughness requirements. According to the customer's requirements honing process, can reach the tolerance range (such as H7, H8, H9, etc.), roughness can reach Ra0.4, ellipticity up to 3 ~ 5 silk range, length length can be up to 8m.
