Precision Reaming Tools for CNC Hole Finishing
In the machining and metalworking industries, precision is paramount. Achieving accurate hole dimensions, smooth surface finishes, and extended tool life largely depends on specialized cutting tools. Reaming Tools play a crucial role, as they can machine holes with extremely small tolerances, making them particularly suitable for hole finishing. Unlike drilling, reaming is a precision machining process that further refines pre-drilled or bored holes to achieve precise diameters and a very smooth surface finish. WDF, as a professional cutting tool manufacturer in China, has extensive experience, and our products are nationally certified; you can purchase with confidence!
How much material should Reaming Tools remove?
The amount of material left during reaming is crucial. For good results, leave 0.1 mm to 0.4 mm of material allowance in the diameter. When Reaming Tool is working, the gap between it and the hole wall can't be too narrow. In that case, it's not actually "biting", but rather rubbing and grinding, resulting in the reamer itself becoming extremely sharp, and the hole wall becoming rough and uneven. Conversely, if the gap is too large, Reaming Tools have to exert excessive force, and if the cutting pressure is too high, it might break, and the hole will be crooked and uneven. Therefore, the appropriate gap size depends on the material being cut and the size of the hole
What are the optimal reaming speed and feed rate?
To achieve a good hole surface finish, the reaming speed is generally 1/2 to 2/3 of the drilling speed for the same material. For example, when machining low-carbon steel, a commonly used speed is 10-20 SFM. The feed rate must be positive and continuous, typically 2 to 3 times higher than the feed rate of a drill bit of the same size. A higher feed rate helps Reaming Tools "pull" itself through the workpiece, resulting in a better surface finish. A pecking feed is not recommended because it easily causes chatter and degrades the hole's surface finish. Always refer to the tool manufacturer's specifications to obtain the most accurate data.
