Cemented Carbide Reamers Selection
Usually the problem is to be noted while reamers are operating including allowance, the depth (diameter), surface roughness, and the hole expansion, selection criteria, such as cemented carbide reamer table:
| Allowance | Depth(L/D) | Surface roughness | Expansion of hole | |
| Brazed reamers | Less is good | <5 | Steel with high precision is difficult | Inconsistency |
| Integral reamers | Less is good | 8~10 | Steel cutting with hole better, but more difficult to reach 6S | Consistency |
| Broach | Reference to prefabricated holes with drill | <5 | Steel cutting can get high-precision surface | Consistency |
| Barrel reamers | Slightly more is better | Can be quite deep | Ra6 ~ 12μm steel, aluminum castings Ra3 ~ 6μm | Consistency |
Particular attention to the processing method for oil, that is, it must seriously consider how to cleverly chip removing. For example, compared to the starting horizontal machining using the vertical drilling process, chips and oil will Next outflow, thus reducing the clogging of chips and film discontinuity, and will improve the quality of the processed surface. Especially in the deep hole machining with hole cemented carbide reamers, must pay attention to.
