Reaming machines hold a significant position in the realm of secondary machining. As a dedicated supplier of reaming machines, I’ve witnessed firsthand the wide – ranging and versatile applications of these remarkable tools across various industries. In this blog, I’ll delve into the in – depth applications of reaming machines in secondary machining, highlighting their indispensable role and the unique advantages they bring. Reaming Machine<\/a><\/p>\n

<\/p>\n

Precision Hole Finishing<\/h3>\n

One of the most fundamental and prevalent applications of reaming machines is precision hole finishing. In the manufacturing process, after drilling a hole, the resulting hole may have rough edges, irregular diameters, or unacceptable surface roughness. A reaming machine comes into play to address these issues.<\/p>\n

The reamer, the core tool of a reaming machine, is designed with multiple cutting edges. When the reamer is inserted into the pre – drilled hole and rotated, it removes a small amount of material from the inner surface of the hole. This fine – tuning process can improve the dimensional accuracy of the hole to within a very tight tolerance range, often within several micrometers. For example, in the aerospace industry, where components demand extremely precise dimensions, reaming machines are used to finish the holes in turbine blades and engine casings. These holes need to have exact diameters to ensure the proper fit of shafts and other moving parts, which is crucial for the overall performance and safety of the aircraft.<\/p>\n

Beyond dimensional accuracy, reaming also significantly enhances the surface finish of the hole. The smooth surface inside the hole reduces friction, which is advantageous in applications such as hydraulic cylinders. In a hydraulic system, smooth – walled holes in cylinders ensure the efficient movement of pistons, preventing leakage and improving the overall efficiency of the system.<\/p>\n

Deburring and Edge Abating<\/h3>\n

During the primary machining processes like drilling or punching, burrs often form on the edges of the holes. These burrs can be sharp and uneven, which pose a threat in subsequent assembly operations. A reaming machine can effectively remove these burrs.<\/p>\n

The action of the reamer passing through the hole shaves off the burrs, leaving a clean and smooth edge. In the automotive industry, for instance, when manufacturing engine blocks, there are numerous holes for various purposes such as coolant passages, oil channels, and bolt holes. Reaming these holes not only ensures the correct size but also eliminates burrs. Burr – free holes prevent damage to gaskets and seals during assembly, reducing the likelihood of leakage and improving the reliability of the engine.<\/p>\n

Moreover, reaming can also perform edge abating. Sometimes, the edges of the holes need to be slightly chamfered to facilitate the insertion of parts. The reamer can be configured to create a precise chamfer at the entrance or exit of the hole, which is essential in applications where parts need to be inserted smoothly, such as in electrical connectors.<\/p>\n

Enlargement of Small Diameter Holes<\/h3>\n

In some cases, the pre – drilled holes may not be of the desired diameter. A reaming machine can be used to gradually enlarge these holes to the required size. This is particularly useful when dealing with small – diameter holes in materials that are difficult to machine.<\/p>\n

For example, in the watchmaking industry, the components are very small and require high – precision machining. Holes in watch gears or balance wheels may need to be enlarged slightly to accommodate shafts or pivots. Reaming machines can perform this task with high precision, ensuring that the components fit together perfectly. The ability to enlarge small – diameter holes also allows for more flexibility in the design and manufacturing process. Manufacturers can start with a standard – sized drill bit and then use reaming to achieve the exact diameter they need, rather than searching for a specific – sized drill bit for every single hole.<\/p>\n

Corrections to Hole Geometry<\/h3>\n

Not all pre – drilled holes have perfect circularity or straightness. In secondary machining, reaming machines can effectively correct these geometric imperfections.<\/p>\n

The reamer’s cutting action helps to round out non – circular holes. It can correct ovality, which may occur due to factors such as drill bit wear or improper drilling techniques. By rotating the reamer in the hole, it evenly removes material from the high – spots, gradually bringing the hole back to a more perfect circular shape.<\/p>\n

In addition, reaming can also improve the straightness of the hole. When a long – hole is drilled, there may be a slight deviation from a perfectly straight path. The reamer can straighten the hole by following the desired axis and removing the excess material on the curved sides. This is of great importance in applications like the manufacturing of long – shaft bearings, where the straightness of the shaft hole ensures the smooth rotation of the shaft and reduces wear and tear.<\/p>\n

Processing of Special – shaped Holes<\/h3>\n

Although reaming machines are commonly associated with circular holes, they can also be adapted to process special – shaped holes. With the development of tooling technology, custom – designed reamers can be used to create non – circular holes such as square, hexagonal, or oval holes.<\/p>\n

In the mold – making industry, special – shaped holes are often required in molds for plastic injection or die – casting. Reaming machines can be used to finish these holes with high precision. For example, a hexagonal hole in a mold may be used to hold a corresponding hexagonal insert. By using a specially designed hexagonal reamer, the reaming machine can create a hole with accurate dimensions and a smooth surface finish, ensuring a proper fit between the insert and the mold.<\/p>\n

Compatibility with Different Materials<\/h3>\n

Reaming machines are incredibly versatile in terms of the materials they can work with. They can be used on a wide range of materials, including metals such as steel, aluminum, and copper, as well as non – metals like plastics and composites.<\/p>\n

When working with metals, the reaming process can be optimized according to the hardness and machinability of the material. For hard metals like stainless steel, a more rigid reaming machine and a slower cutting speed may be required to ensure precision and prevent tool wear. On the other hand, softer metals like aluminum can be reamed at a higher speed with less force.<\/p>\n

For non – metals, reaming machines offer a clean and efficient way to finish holes. In the production of plastic components, reaming can improve the dimensional accuracy and surface finish of the holes, which is important for the assembly and functionality of the final product. Composites, which are increasingly used in modern industries due to their high strength – to – weight ratio, can also be processed by reaming machines. Specialized reamers can be designed to handle the unique properties of composites, such as their layered structure and the presence of fibers.<\/p>\n

Cost – effectiveness in Secondary Machining<\/h3>\n

One of the significant advantages of using reaming machines in secondary machining is cost – effectiveness. Compared to other precision machining methods, reaming is a relatively simple and inexpensive process.<\/p>\n

<\/p>\n

The initial investment in a reaming machine is relatively low, especially when compared to more complex machining centers. Additionally, the cost of reaming tools is relatively affordable. Reamers can be resharpened multiple times, extending their service life and reducing the overall tooling cost.
\nIn mass – production scenarios, using reaming machines for secondary machining can significantly improve production efficiency. Since reaming is a relatively fast process, it can quickly finish a large number of holes, reducing the overall production time and cost per part.<\/p>\n
