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.
