What is an Arbor Press
An arbor press is a small hand-operated press, a common fixture in many workshops. It is loved for its ability to apply precise force to press or stamp objects. Its simplicity is its beauty, yet its design is a work of mechanical art. The arbor press's base and additional components allow it to do small jobs with precision that larger presses can't.
The arbor press mechanism is very simple. The tool converts a small force applied through a handle into a much larger force, making pressing, stamping, bending, and assembling materials easy. The frames are cast iron for enhanced strength and durability, and incorporate a flanged spine design that adds rigidity to the press body. The ram is driven by a rack and pinion mechanism, which allows it to hold bits and tools with the help of a magnetic insert. We will cover the different types and components to get to know arbor presses better.
Types of Arbor Presses
Arbor presses come in different types, each for different tasks. A manual arbor press, for example, is a small tool used for smaller jobs like:
- Staking
- Riveting
- Installing
- Bearing configuration
It's the tool of choice for fine work.
A 4-ton ratchet arbor press stands out because of its ratcheting mechanism. This feature allows for fast pressing speed and more pressing force, which is good for jobs that require more force.
Compound leverage arbor presses are also available. These presses use a ratcheting system to build and multiply leverage, making them suitable for jobs that require more pressing force.
Components of an Arbor Press
An arbor press is more than the sum of its parts. Every component, from the frame to the handle, contributes to its functionality and performance. The press has:
- A base
- A vertical frame
- A moving ram
- An arbor
All these components allow the arbor press to do small jobs.
- The ram applies force to the workpiece for pressing operations. Punches or tools can be added to the end of the ram for different pressing applications, such as riveting, squeezing, bending, and punching.
- The anvil, a machined steel component with multiple slot positions to hold workpieces of different sizes and shapes
- The base provides stability and a flat surface to mount dies, fixtures, and other components necessary for the press to work. The press bases are machined for maximum stability and drilled to permit side mounting options, enhancing the overall performance and adding rigidity to the press body.
These components work together to make the press work.
Choosing the Right Arbor Press
Choosing the right arbor press involves:
- Tonnage
- Stroke length
- Throat depth
- Workspace constraints
Picking an arbor press that feels right will improve your work and productivity. All frames are made of cast iron for durability, and the industry offers a wider range of tonnage and sizes to meet various needs.
Tonnage and pressure, stroke length, and throat depth all affect the force of the arbor press. Workspace considerations are important in determining where and how the press will sit. We will go into more detail to help you choose the right arbor press, including the variety of sizes in arbor presses available to meet different needs.
Tonnage and Pressure
Tonnage and pressure are the two most important considerations when choosing an arbor press. They affect the force the ram or head can apply, and more tonnage and pressure mean more force.
Our arbor presses offer a wider range of tonnage options, emphasizing the variety of models available to meet diverse customer needs. Determining the tonnage needed for your arbor press job is key; underestimating could mean inefficient pressing. The formula for calculating the tonnage varies depending on the application, but a common method is calculating the torque for the desired force.
Stroke Length and Throat Depth
When choosing an arbor press, stroke length and throat depth are two more important considerations. The stroke length varies by model and is the distance the ram travels per cycle. The throat depth is the height of the ram and allows for larger workpieces and more applications, making the press more versatile.
Consider the size of the part you are working with when choosing the stroke length and throat depth for your job. Ensure the press's stroke length is enough for the material size, and the throat depth can accommodate the size of the pressed part. This will make the press efficient and versatile, ensuring maximum stability and drilled bases for various mounting options.
Size and Workspace
The size of the arbor press and your workspace are important considerations when choosing the right press for you. Arbor presses are designed to sit on a table or sturdy bench and offer versatile mounting options, including bench or pedestal mounting, making them perfect for small—to medium-sized workspaces. Despite their compact size, they are more cost-effective and space-saving than larger industrial presses.
An arbor press must be centered and secured to prevent movement or misalignment during pressing. Also, ensure enough clearance for the workpiece, especially if the press has a rotating base plate with slots for arbors of different diameters.
