Abstract
The utility model relates to an improved diamond roller, which comprises a steel base body with a spiral skewed tooth and a diamond layer welded on the skewed tooth. The utility model is characterized in that in the skewed tooth of the roller, the spiral angle beta is changed into 50 DEG to 70 DEG, and the optimum angle is from 59 DEG to 61 DEG. Because the spiral angle beta of the skewed tooth is obviously enlarged, the gap of a diamond segment can not cause the phenomenon of grinding leakage, the surface quality is obviously increased, and the surface of a workpiece is flat and smooth. The roughness of the surface of the workpiece can be Ra < or = 3.3 mm, and the surface finish can be five level to six level.
Description
Technical field
The utility model relates to grinding tool, the diamond running roller of hard brittle materials such as particularly a kind of grinding refractory material, ceramic tile.
Background technology
The diamond running roller is mainly used in the grinding of hard brittle material, as refractory material, vitrified tile etc.Require the interior grinding of large tracts of land scope to get smooth, smooth.The diamond running roller is a kind of big specification diamond abrasive tool, forms by cylindric steel matrix and diamond working layers, and surperficial similar helical gears, the diamond working layers block-by-block is welded on the spiral helical teeth.Each diamond segment is a rectangular block, and its length is 20-25mm normally, wide about 10mm.The domestic and international at present diamond running roller of manufacturing, the helical angle of its helical teeth is all selected less than 45 °.Can not paste very closely between each piece diamond segment of welding, the slit of 0.1-0.2mm is often arranged therebetween, the leakage mill phenomenon of diamond layer might be caused in this slit, makes the coarse injustice of surface of the work, and phenomenons such as barring, groove are often arranged.Workpiece surface roughness can only reach Ra=25-50 μ m, and surface smoothness has only ▽

Summary of the invention
The purpose of this utility model is to avoid the above-mentioned difficulties of prior art, and a kind of improved diamond running roller is provided, and surface smoothness, fineness after the grinding are significantly improved.
Solution of the present utility model is: change the helixangle of traditional diamond running roller helical teeth into 50 °-70 °.Through preferred optimal helical angle β is 59 °-61 °.
The utility model compared with prior art because the helical teeth helixangle obviously strengthens, the gap between the diamond segment can not caused and be ground phenomenon with Louing.Running roller with such manufacturing carries out grinding, and workpiece surface roughness can reach Ra≤3.3 μ m, and surface smoothness reaches ▽ 5-▽ 6, thereby surface of the work is more smooth, smooth, and surface quality significantly improves.
Description of drawings
Accompanying drawing is a diamond running roller helical teeth helical angle structural representation.
The specific embodiment
Referring to accompanying drawing, on the steel substrate 1 of running roller, be furnished with 20-30 bar rectangle helical teeth 3, along helical teeth 3 surface soldered diamond layer 2 is arranged.Diamond layer 2 is made up of a piece rectangle diamond segment, and its gap is 0.1-0.2mm.Because the existence in gap may cause Lou mill phenomenon.The helixangle of the utility model diamond running roller helical teeth increases to 50-70 °, is 59-61 ° through preferred best angle, and the not enough 45 than traditional is significantly improved.After helixangle increased to 60 °, each block gap of diamond layer just can not take place to leak the mill phenomenon in grinding process, thereby workpiece can barring and groove occurs, surfacing, smooth.
Claims (2)
1, a kind of improved diamond running roller comprises the steel substrate (1) of band spiral helical teeth and is welded on diamond layer (2) on the helical teeth (3) that the helixangle that it is characterized in that said running roller helical teeth (3) is 50 °-70 °.
2, diamond running roller as claimed in claim 1 is characterized in that said helixangle is 59 °-61 °.
