The Arbor Press: Your One-Stop Shop
Are you thinking of getting an arbor press for your workshop for precision and controlled force? An arbor press is a versatile hand-operated tool that provides great accuracy and leverage for machining, forming, and assembly projects. This guide will cover types, applications, and selection tips to help you find the right arbor press for your needs.
Main Points
- Arbor presses are used for precise force on small jobs. Manual, ratchet, and leverage are designed for tasks and force requirements.
- To select the right arbor press, you need to consider tonnage, pressure, stroke length, throat depth, and workspace constraints to achieve enough force, workpiece size compatibility, and fit in the work environment.
- Proper use and maintenance of an arbor press is critical for safety and longevity. This includes secure installation, regular servicing, and following operational best practices like controlling pressure and wearing safety gear.
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 easily. The ram has a hole at one end to hold bits and tools with the help of a magnetic insert. To get to know arbor presses better, we will cover the different types and components.
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.
A 1-ton compound leverage arbor press uses a ratcheting system to build and multiply leverage. It is good 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 like 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.
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 for you will improve your work and productivity.
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.
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.
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 to calculate 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: 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. Make sure 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.
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, 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.
When installing an arbor press, it must be centered and secured to prevent movement or misalignment during pressing. Also, make sure there is enough clearance for the workpiece, especially if the press has a rotating base plate with slots for arbors of different diameters.
Arbor Press Applications
Arbor presses are versatile in many applications. They can be used for:
- Punching
- Riveting
- Installing bearings and components
- Working with dies and sockets
These are used in industrial environments for many tasks.
Arbor presses are used in many industries:

This shows their versatility in many industrial applications.
Punching and Riveting
Arbor presses are the go-to tool for punching and riveting. They are also used for pressing pins, rivets, and eyelets, stamping leather crafts, and making metal jewelry.
Down pressure is required when punching material; this helps drive the punch through the material. To get better results, grind some shear into the end of the punch.
However, using an arbor press for riveting will give you a smoother and more accurate rivet setting than using a hammer.
Installing Bearings and Components
Arbor presses are also used to install bearings and other components. They apply uniform pressure to the bearings or components to install them in a precise position without damaging them.
During bearings installation, follow these steps:
- Lubricate the shaft and the bearing.
- Controlled press fit.
- Apply even force to the inner ring without touching the ball bearings or outer ring.
For stability, bolt the arbor press to a bench or floor.
Working with Dies and Sockets
Arbor presses can be used for:
- Punching and riveting
- Installing bearings
- Removing bushings
- Installing control arm bushings
- Using sockets as dies for specific applications
When choosing dies and sockets for arbor press use, consider the application and the material being worked with. The dies should be designed for the task, and the material should be chosen according to the job's specifications.
