Most industries use solid carbide reamers, which work well for ferrous and non-ferrous applications. Since different flute configurations can be utilized to replace different boring techniques, such as single-point boring, they provide application-specific solutions and can significantly enhance bore finishing.
A Brief Overview of a High-Performance Reaming
Reaming finishes a bore by removing a small quantity of material with a cutting tool. Reamers are intended to deliver final diameters and surface finishes rather than bore placement. The condition and placement of the pre-reamed bore are critical since a reamer usually follows it.
High-performance reaming elevates reaming to new heights. It is done at high speeds and feeds using multi-edge tools to obtain excellent hole quality, close dimensional tolerance, and high surface gloss. Modern high-performance reamers are available with carbide, cermet, or PCD tips. The application of current thin film coatings can significantly improve performance.
The Advantages of Carbide Reamers
A Reduction in Scrap
When working with costly materials, minimizing scrap is incredibly crucial. For instance, manufacturers frequently make fewer parts made of expensive materials like titanium, Inconel, and other materials in the aircraft industry. A high-performance reamer can help manufacturers maintain consistent hole sizes throughout the tool's life and dramatically reduce scrap rates.
Increased Carbide Reamers Feeds and Speeds
Compared to single-point boring, high-performance reamers' many cutting edges enable faster feed rates and shorter cycle times. In contrast to a single insert in a single-point boring tool, high-performance reamers have four to 16 teeth; the increase in feed rate can be four to 16 times faster. When a bore needs to be the right size and finish, single-point boring is employed; however, because there is only one cutting-edge working, it is naturally slower.
Setting the reamer is simple with high-performance reaming because the initial bore is excellent. Because the tool is ground to the correct diameter, there is no need to alter the diameter. Furthermore, reaming is a solid and secure technique that does not necessitate as much adjustment as single-point boring.
The diameter of single-point finish drilling heads can be precisely changed. While expandable reamers can be modified in diameter to compensate for wear, they cannot be increased to accommodate differing hole sizes.
Decrease Cycle Time
Reamers also improve surface finishes by flattening peaks. Fine boring is fundamentally turning, and with turning, you will always have a microgroove and a small profile. The profile will still exist even if you flatten it with a wiper insert.
Reamers of Other Types
Hand reamers are divided into fluted and rose reamers, which feature a little taper on the cutting end to help them enter the hole correctly. These reamers can be solid or extensible, but their expansion is limited to a certain degree. The blades are frequently arranged in an uneven pattern around the body of the reamer. It is positioned to limit the tendency of a reamer to chatter due to slippage or torsion.
For optimal machine operation, shell reamers are installed on customized arbors that fit using driving pins. These are primarily used for free-cutting material and accurately reaming holes to the correct size. These reamers are used in drill presses, lathes, and automatic screw machines, among other things.
Floating reamers fix misalignment between the reamer's axis and the previously drilled hole. These reamers include two interchangeable, adjustable cutting edges that are kept together in a single reamer slot and free to float in any direction. Only spinning workpieces on turret lathes can be used with these reamers.
