Cemented Carbide Reamers Use
Assembly precision: the use of cemented carbide reamers pays attention to be loaded into the machine, the front end of the feed section of cemented carbide reamers jitter control below 0.02mm. In cutting, to always maintain this accuracy can be used to guide sleeve.
the feed part of the cutting edge gap check: even if the jitter of the reamer can be restricted within a desired range, but in fact often the cutting edge chipping, notched, or lack of a good surface roughness and the holes accuracy. Therefore, prior to use, not only to check the cemented carbide reamer jitter, also check the cutting edge itself has no chipping, and the gap.
oiling method: processing oil lubrication can not only make the polishing effect is more significant, can help chip smoothly discharged, so that the accuracy and processing accuracy of the surface of the hole to further improve. Attention to the selection of the direction of a good oiling to oil, especially in some dedicated horizontal machine processing, to make the oil direct injection to the cutting edge of the reamer, then consider the hinge as shown with hole the knife is a good choice.

Guide sleeve: in order to get high accuracy, especially in higher accuracy requirements of the machined surface should use the guide sleeve. In this case, the problem is how to select the gap between the guide sleeve and reamers. Gap value of about 0.005mm is the best, if not reach, the maximum not and should not exceed 0.02mm.
workpiece clamping: conducting high accuracy requirements reamer processing, the accuracy and the roughness of the machined surface of the hole by the workpiece clamping way, especially the impact of the high cutting speed so must be carefully considered clamping methods. While clamping to be considered not only the direction of down direction, taking into account the direction of feed.
