While hand deburring is certainly successful with highly-trained individuals, the output is often far below what manufacturers need to meet their demand. Too often, hand deburring results in more part scraps and lack of inconsistency, which translates to lower quality products.

Robotic deburring can be highly cost-effective and consistent, yet finding the right robotic deburring tool can be challenging. Robots must be properly programmed to execute successful deburring, and there are certain factors to take into account when choosing the right tool.

Here are three tips to help you make the right decision when searching for robotic deburring tools for your automation needs!

Consider Part Geometry

The size, shape, weight, and complexity of your parts that need to be deburred is an essential consideration when looking for the right deburring device. Not every robotic deburring tool can successfully deburr parts of every shape.

The tool you choose will vary based on the location and size of the burrs and how well your tooling complies with the device—in other words, how well it consistently makes contact with and applies force to the part for successful deburring.

If your parts are complex and have tight spaces, you may need a radially compliant device. However, if your burrs are consistently on the edge of the product, axially compliant could be a better choice. It all depends on what your parts look like and how successful your tooling will be to remove burrs without compromising part quality.

Look for Variable Speed Options

Choosing variable speed deburring tools over fixed RPMs gives you greater flexibility. Variable speeds gives your tooling the ability to automatically adjust to part differences, which saves you time and effort on programming. Many different materials can be deburred with just one variable speed robotic deburring device.

Variable speed devices aren’t limited to burrs of a specific size and shape as fixed RPM models are. When deburring, the burr needs to be completely removed, but you don’t want to take off any more material than necessary, which can affect your part’s quality and function. This alone is difficult for many deburring robotic devices to accomplish.

Fortunately, variable speed gives you the flexibility you need for your parts to increase consistency while reducing programming efforts.

Consider Radially Compliant Deburring Tools

Axially compliant tools can be effective for specific applications such as edge deburring. However, for the majority of applications, parts and burrs aren’t consistent, which makes having a robotic deburring tool that can accommodate part and burr changes essential.

Radially compliant deburring tools easily accommodate changes without the need to manually reorient the robot, saving you time and effort. With radially compliant devices, manual deburring is mimicked, giving you consistent force and the ability to get into tighter areas.

With radially compliant deburring tools, you can also remove parting lines and flash, whereas axially compliant tools wouldn’t. Considering radial instead of axial for your deburring processes gives you a greater range of flexibility without sacrificing results.

When choosing a robotic gripper for your automation needs, your best choice all depends on your application. There are a range of End of Arm Tooling (EOAT) devices that may work for your process, but that doesn’t mean that every tool will be the most advantageous.

At RAD, our complete line of grippers covers all your automation specifications. No matter what your needs are, we have the make and model to meet them with our industry-leading products. All of our grippers are designed with maximum durability to last.

We offer 2-jaw, 3-jaw, and collet robotic grippers for your applications. But what are the different uses for these grippers and their particular features?

2-Jaw Grippers: Best for Consistent Processes 

2 Jaw GripperExcellent for items with flat surfaces, 2-jaw grippers are an affordable, dependable choice that work with a wide range of applications. Our 2-jaw parallel grippers are incredibly versatile and we have models designed for use in dirty or harsh environments.

With two points providing even pressure on the item for increased stability, 2-jaw grippers are best for parts that are all similarly sized. However, 2-jaw grippers may not be your ideal choice for fragile items.

With adapter plates for easy installation, 2-jaw grippers can be customized for your manufacturing process, whether you need to grip items from the side or top.

3-Jaw Grippers: For Larger or Irregular Parts

3 Jaw GripperDesigned to carry larger objects than 2-jaw grippers, 3-jaw grippers do well with irregularly-shaped parts, as the three points that touch the part self-adjust to the shape. It’s important to know that 3-jaw grippers can only grip parts axially, and they put even pressure on each point for increased stability.

With better centering and a secure grip, 3-jaw grippers provide accurate performance and can be great options for cylindrical or even surfaces. Like 2-jaw grippers, be cautious when choosing these for delicate parts.

All of our 3-jaw grippers at RAD work well in harsh environments and are one of our most popular designs for a variety of automation processes!

Collet Grippers: Best for Delicate or Similarly-Sized Parts

GripperCollet grippers deliver high-speed performance for parts of consistent shape and size. Providing 360 contact with even pressure, these robotic grippers are an excellent choice for delicate parts.

Adjustable to fit different-sized parts for various applications, collet grippers provide flexibility, but are ideal for parts that have tight tolerances. Easy to change out for maintenance and even field reparable, collet grippers can help reduce downtime.

With their centering capabilities, collet grippers are also an excellent EOAT device for deburring parts or polishing parts. Collet grippers can also work well with cylindrical parts, just as long as part shape and size are consistent.

Why RAD?

At RAD, our robotic grippers are designed to outperform and outlast. You won’t have to change your gripper for many years, even if it’s operating in a challenging environment.

A robotic collet gripper is a tool designed to attach to your robot to transport products in your automation line. With a robotic collet gripper, you can automate processes that include gripping parts that are identical in size.

The collet will open and extend to grab the item and then close and retract to move it. By automating your transport processes for items with a collet gripper, you can prevent damage to your materials and increase your manufacturing efficiency!

Benefits of Using a Robotic Collet Gripper

There are many benefits of using a robotic collet gripper for the proper applications. These grippers:

  • Work quickly. Since they have a high clamping force, collet grippers can rapidly perform their task, allowing you to increase productivity.

  • Center parts. Their centering capabilities allow you to use collet grippers for deburring or polishing parts for safety and efficiency.

  • Perform optimal gripping. Collet grippers use 360-degree contact on your item, which provides even pressure to prevent damage to even the most delicate parts.

  • Have a narrow profile. This allows the gripper to reach for items in constricted areas where materials may be crowded together.

  • Are adjustable. You’re able to pneumatically adjust the collet’s gripping force, which means you can adapt the gripper to function with different parts. They’re also flexible enough to give you hundreds of different sizes for different parts.

  • Maintain durability. Its aluminum casing keeps the tool light while the collets and brushings are made of durable steel.

Robotic collet grippers from RAD are also easy to change out, allowing you to quickly swap out a gripper for maintenance or repairs to keep your automation processes up and running.

Our collet grippers can also be repaired in the field to reduce downtime, and should you ever need a replacement part, we can usually ship items that same day to help you get your replacement component as soon as possible.

Are There Customizations for Collet Grippers for My Application?

You can easily customize collet grippers to suit your particular application. For example, for those who need collet grippers for harsh environments, we offer Viton seals, which help your gripper resist damage from corrosive fluids and high temperatures.

Other customizations include adapter plates for easy installation, collision sensors to protect your investment, and tool changers so that your robot can perform different operations without the need for you to manually swap out tools.

With customizations for your collet grippers, you can ensure your robot tooling is perfectly adapted to your environment for maximum performance.

When to Consider a Robotic Collet Gripper

Robotic collet grippers are excellent for a variety of applications. However, since they’re designed for parts with particular dimensions, these grippers are best used for:

  • Parts that are all the same size

  • Items that have tight tolerances

  • Parts with cylindrical surfaces

  • Holding items that need to be polished, grinded, or deburred

If you’re not sure whether or not a collet gripper would be the ideal fit for your particular application, our team at RAD can help you discover if these grippers are the best choice for you!
