Reaming removes a small amount of material from the surface of holes. It is done for two purposes:
1. To bring holes to a more exact size
2. To improve the finish of an existing hole
Important Point:
Boring: Boring is an operation to enlarging an existing hole, which may have been made by a drill or maybe the result of a core in a casting.
Drilling: Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular cross-section in solid materials. The drill bit is a rotary cutting tool.
Reaming: Reaming is a sizing operation that removes a small amount of metal from a hole already drilled. It is done for two purposes: to bring holes to a more exact size and to improve the finish of an existing hole.
Mistake Point:
Drilling is used to enlarging the diameter. Reaming operation is meant to slightly increase the size and to provide a better tolerance and surface finish of an initially drilled hole.

Reaming: Purpose and Explanation

Reaming is a machining operation used to improve the finish and accuracy of a hole that has already been drilled or bored. It involves enlarging the diameter of the hole by removing a small amount of material from the walls of the hole. The purpose of reaming is to achieve a precise and smooth surface finish, as well as to ensure the correct diameter for the desired fit or function.

1. Initial Hole Creation:
The primary purpose of reaming is not to create a hole initially. Drilling or boring operations are typically used to create a hole of a certain diameter. Reaming comes into play after the initial hole has been made.

2. Enlarging the Diameter:
While reaming does involve enlarging the diameter of the hole, it is not meant to significantly increase the hole size. Reaming is usually performed to remove any excess material or irregularities left behind by the initial drilling or boring process. It helps to achieve a more precise and accurate diameter for the hole.

3. Improving the Finish:
The main purpose of reaming is to improve the finish of the hole. The reaming tool, known as a reamer, has multiple cutting edges that remove small amounts of material as it is rotated within the hole. This action helps to smooth out any imperfections, such as burrs or roughness, left by the previous machining operation. The result is a smoother and more uniform surface finish.

4. Achieving the Correct Diameter:
One of the key objectives of reaming is to achieve the correct diameter for the hole. The reamer is carefully selected to match the desired hole size, and the cutting edges of the reamer remove just enough material to achieve the precise diameter required for the application. This ensures that any components or fasteners intended to fit into the hole will have the proper clearance or interference fit.

In summary, the purpose of reaming is to improve the finish of a hole by removing small amounts of material and achieving the correct diameter. It is not meant for initial hole creation or significant enlargement of the hole. The result is a more precise, accurate, and visually appealing hole that meets the requirements of the desired fit or function.
