At Numberall, we pride ourselves in offering a diverse line of high-quality marking machines, each with their own specific use. When it comes to marking small round parts, we’ve designed specialized presses that can get the job done more efficiently and effectively, with the same accuracy and quality that our equipment has become known for throughout the 90 years we’ve been in business.
Why Use a Roll Marking Machine?
Roll marking, or cylindrical marking, is a method of marking solid or hollow round parts, such as pipes and gears. At Numberall, we design our roll marking machines specifically for light duty marking of round parts with an even depth of impression. With typical flat metal marking equipment, it can be difficult if not impossible to get an even mark across a round part. Will roll marking, the part rotates, or rolls, with the indenting device to ensure each character is distributed evenly and with the same depth of impression. Our versatile roll marking equipment can be used on a wide range of materials across many different manufacturing industries, including firearms, automotive parts, pipe fittings, and more.
What are the Roll Marking Machine Options?
At Numberall, we offer two options for roll marking equipment — the Model 301 Hand-Operated and Model 301A Air-Operated presses. Although similar, these models offer unique capabilities that make them suitable based on the volume of our customer’s marking needs.
The Model 301 is a hand operated machine which is capable of mark round parts with characters up to 1/4” in aluminum, or 5/32” characters in mild steel. Despite its compact bench-top size, this press is able to incorporate oversized endplates for more clearance. To begin stamping, you will need a marking device. Many of our numbering heads can be used with the Model 301, including Model 23 Type Holder, Model 70P Non-Automatic Numbering Head, and Model 50P Automatic Numbering Head. Each unique numbering head offers customization when paired with the 301 roll marking press.
The Model 301A is ideal for high production application. This model uses an air cylinder for power and includes a control valve. The Model 301A can stamp characters of the same size, in the same material as the Model 301. The Model 301A can also incorporate oversized endplates for larger diameter parts — just like the Model 301. Similar to the Model 301, numbering heads, type holders, or marking dies are used in conjunction with the Model 301A. The key differentiator is that the Model 301 is air-operated rather than by hand, which allows for large scale production marking needs.
Can Roll Marking Machines be Customized?
No matter the shape or size of the item you want to mark, it’s likely that we can customize one of our roll marking machines to meet your needs. In addition to the oversized endplate options, Numberall has designed custom fixtures to stamp the edges of coins and medallions without marring the surfaces. We also have fixtures with interchangeable arbors for stamping hollow parts or rings. For parts with varying part diameters or stepped parts, we can modify our standard adjustable holding fixture rollers to hold the part securely when marking.
One example of our custom roll marking capabilities is an application we created to mark CO2 bottles. In this design, we created special holding fixtures to mark the neck of the bottle at an angle. To see this application in action, view our recent blog post: Numberall’s Custom Application to Mark CO2 Bottles. Our roll marking machines offer both precision and flexibility for our customers looking to indent round parts.
