What Is Reaming & Reamer And Their Differences

Reaming is an important process in CNC machining services, and its main purpose is to join parts or components so that they can rotate or oscillate relative to each other and move at a specific angle or direction. Reaming has a wide range of applications in the manufacturing industry and is capable of fulfilling a wide range of functions and needs, from simple connections to complex mechanisms. In this article, we will discuss in detail the purpose of reaming and its application in different fields.

Basic purpose of reaming

The basic purpose of reaming is to achieve relative motion between two or more components, which is usually rotational or oscillatory, depending on the design and use of the reamed hole. The following are the main purposes of reaming:

Joining members: reaming allows two or more members to be joined together to form an integral unit. These members can be made of metal, plastic, wood or other materials, and by connecting them through a reamed hole, they can move relatively freely while maintaining a certain degree of stability.

Realization of rotational movement: reaming allows the members to rotate about an axis. This rotary motion can be continuous or restricted within certain limits, depending on the design of the reamed hole. Rotary motion is used in a wide variety of mechanical devices, such as the opening and closing of doors and the movement of pistons in engines.

Realization of oscillating motion: In addition to rotary motion, reamed holes can also realize oscillating motion, also known as swinging. This movement allows the member to swing at an angle in a plane, which is very common in applications such as doors, suspensions and robotic arms.

Adjustment of angle and orientation: Reamed holes can also be used to adjust the angle and orientation between members. By designing different types of reamed holes, different degrees of adjustment can be achieved to meet specific needs. This is very useful in various engineering and manufacturing fields.

Transmitting forces and torques: Reamed holes not only enable movement, but also transmit forces and torques. This means that reamed holes are not only used for connecting components, but also for transmitting power and torque, e.g. in mechanical drive systems.

Realization of specific working mechanisms: Reamings can also be used to realize specific working mechanisms, for example to allow a robot arm to move in multiple degrees of freedom, or to allow a vehicle's suspension system to adapt to different road conditions. Through cleverly designed reamed holes, a variety of complex mechanical movements can be realized.

Types of reamed holes

There are many types of reamed holes, each with a different design and application. The following are some common types of reamed holes:

Fixed Reaming: Fixed reaming is the simplest type and is usually used to connect two members and allow them to rotate around an axis. This type of reaming does not allow for any other movement of the members relative to the axis.

Oscillating ream: An oscillating ream allows the members to swing in one plane, but does not allow rotation about an axis. This type of reaming is commonly used in applications such as doors and suspension devices.

Swivel Ream: A swivel ream allows the member to rotate about an axis, but does not allow for oscillation. This type of reaming is commonly used in engine piston movement and mechanical rotation devices.

Ball Reaming: Ball reaming is a complex type of reaming that allows the member to move freely in three dimensions, including rotation and oscillation. This type of reaming is commonly used in robotics and multi-degree-of-freedom mechanisms.

Link reamings: Link reamings are used to connect two components and allow them to rotate relative to each other within a specific angle range. This type of hinge is commonly used in vehicle suspension systems and door hinges.

Hinge Hinge: The hinge hinge is a special type of swing hinge, often used in applications such as doors, boxes and book covers, which allows the member to rotate about an axis and swing in a plane.

Oscillating-Rotating Ream: This type of reaming allows the member to oscillate in one plane and rotate about an axis. This is useful in some robotic arms and camera mounts.

What are PVC pipe reamers used for?

A pipe reamer is a specialized cutting tool used in pipe machining, which plays an important role in pipe Cnc Plastic Machining manufacturing, installation and maintenance. The main uses of pipe reamers cover a wide range of sectors including manufacturing, construction, the oil and gas industry, and water and heating systems.

A pipe reamer is a cutting tool, usually with multiple cutting edges, that is used to cut, trim and machine the ends or edges of pipes. These edges are capable of chipping away the outer material of the pipe to give the pipe end the desired shape and smoothness. Pipe reamers are usually made of sturdy materials to ensure their durability in pipeline processing.

How Pipe Reamers Work

Pipe reamers work similarly to other reamers in that they gradually remove material from the end of the pipe by cutting or planing to achieve the desired size and shape. The cutting edge of a pipe reamer is designed with a specific angle and geometry to ensure accuracy and smoothness of the cutting process. When using a pipe reamer, it usually needs to be inserted into the end of the pipe and cut by rotating or applying force.

Uses of Pipe Reamers

Pipe reamers have a wide range of uses in various fields and their main role is to trim, process and manufacture pipes to meet different needs and standards. The following are the main uses of pipe reamers:

Manufacturing of pipes

Pipe reamers play a key role in the manufacturing process of pipes. When manufacturing pipelines, it is often necessary to trim the end of the pipeline to the desired shape and size to ensure that it meets engineering requirements and standards. Pipe reamers are used to chip away irregularities or excess material from the end of a pipe to give it the correct shape and smooth internal and external surfaces. This helps to ensure that the process of joining and installing the pipe runs smoothly.

Trimming Pipe Ends

During pipeline installation and maintenance, it is often necessary to trim the ends of pipelines to ensure that they are flat, smooth and meet connection requirements. Pipe reamers are used to trim pipe ends to remove any damage, corrosion or irregularities that may exist. This is important for pipe connections, sealing and fluid transfer.

Pipe Joining

An important use of pipe reamers is to prepare the ends of pipes for joining. In piping systems, it is often necessary to connect piping to valves, flanges, fittings or other piping segments. Pipe reamers are used to dress pipe ends to ensure that the connection area has a flat surface for a reliable seal and connection.

Pipe Maintenance and Rehabilitation

During the operation of a piping system, piping may be subject to damage, corrosion, or other forms of wear and tear. During pipeline maintenance and repair, pipe reamers can be used to trim damaged portions of the pipeline to restore its function and extend its service life. This saves on repair costs and reduces downtime of the piping system.

Preparing Welded Joints

During pipe welding, it is often necessary to prepare the end of the pipe into the proper shape for welding. Pipe reamers are used to chip away any unevenness or oxidized layers at the end of the pipe to ensure the quality and strength of the welded joint. This is critical to the reliability of the pipe connection.

Adjusting Pipe Diameter

In some cases, the diameter of the pipe may need to be adjusted to suit different engineering needs or fluid transfer requirements. Pipe reamers can be used to cut the diameter of the end of the pipe to achieve the required size and flow rate.
