Reaming

Reaming is a hole finishing process that enables the creation of highly precise and high-quality holes in machining. Its applications range from the aerospace industry to the automotive and machine shop industries, where high demands for surface quality, dimensional accuracy, and uniformity of workmanship are commonplace.

Reaming refers to the machining process where a multi-edged tool, or reamer, is used to finish a hole of a specific diameter or achieve dimensional accuracy. What makes it special is that it allows for high feed rates, resulting in excellent surface quality and precise dimensional tolerances.

Cutting depth, speed, and feed are the cornerstones of reaming. These parameters directly affect the durability of the reamers and the quality of the final outcome. The cutting depth must be adjusted to be optimized according to the material being processed and the desired final result. The same applies to cutting speed and feed; they must be matched to the requirements of the material and the tool.

The properties of the material to be machined are crucial, as different materials require different machining conditions. Reaming hard materials requires special attention to the blade material and geometry, while for softer materials, optimal chip evacuation is important.

The workpiece clamping, spindle clearance, and the quality of the reamer chuck are prerequisites for successful reaming. Poor clamping or defective chucks can lead to blade slippage, poor machining marks, or in the worst-case scenario, tool breakage.

One common mistake is leaving too little or too much allowance in the hole to be reamed. An optimal allowance ensures that the reamer doesn’t wear out too quickly, nor does the machining become inefficient.

The synergy of these factors ultimately determines the success of reaming. Each step in the process requires carefulness and precision, as even a small error can lead to significant weaknesses in the final result.
