Product Introduction:
Reaming is the semi-finishing and finishing of an existing hole to achieve precise size, high surface quality, perfect roundness and cylindricity, etc. In order to gain precise hole in reaming process, the reamer diameter must be defined correctly. Therefore, it is necessary to consider the allowance which is determined by work piece material and machining conditions. It is also necessary to select the cutting conditions correctly in addition to using high precision reamer to achieve good surface quality. The reaming precision is mainly determined by diameter and radial run-out. With respect to cutting condition, it is better to select low speed cutting to improve machining precision, but the upper limit should be considered carefully for higher machining efficiency.
Solid carbide reamers icons code key:
Example: 3101H7-0850:
“3” = reamer
“1” = shank type of straight shank
“0” = external cooling
“1” = right chip flute
“H7” = The precision class of reamed hole reaches H7 specified in GB/T1800-1804
“-0850” = diameter is 8.5mm
