How to Use a Deburring Tool Effectively: Tips and Techniques

In the realm of precision engineering, where accuracy is non-negotiable, the significance of deburring cannot be overstated. Whether in automotive, aerospace, or electronics industries, burrs pose threats to both safety and functionality. Deburring, the process of removing these imperfections, is essential to ensure that the final product meets rigorous quality standards. At Michigan Deburring Tool, we offer a range of deburring tools tailored to meet various needs: from very small hole Micro and Modular tools to larger AutoLock series up to 37mm in diameter and various Custom deburring tools.

Selecting the Right Tool

Choosing the appropriate deburring tool is vital to achieving optimal results. Factors such as the workpiece material type, desired chamfer results, as well as operator capabilities, should be considered. Whether it’s a manual handheld application for smaller volumes or in a CNC machine for larger volume deburring, selecting the right tool sets the stage for success.

Preparing the tool and Workpiece

Before engaging in the deburring process, it’s essential to adequately assess the deburring tool itself, workholding, and the workpiece. This may also involve checking the drill that precedes the deburring tool for wear if an excessively large burr is present after the drilling process. Proper preparation ensures a smoother and more efficient deburring process and provides more consistent results. Stable workholding and minimizing deburring tool runout using collets or heat shrink holders are other factors that can also greatly improve results.

Executing the Deburring Process

With the workpiece and tool prepared, it’s time to start the deburring process. Tool RPM and employing a consistent motion (speeds and feeds) as well as feed direction when engaging the burr, are key to effectively removing burrs and achieving optimal blade life. Coolant application helps with chip evacuation, can extend the life of the tool significantly, and is always recommended whenever possible.

Whether using a hand drill/drill press or any type of CNC machine, maintaining speed control (RPM) and consistent pressure while cutting, yields superior results. Through the application of the correct method, you can guarantee optimal deburring results, prolong blade life, and avoid longer cycle times and unnecessary damage to the workpiece.

Standard CNC operation of our front and rear cutting tools:

  1. Start the spindle before entering the workpiece (The Spindle should remain running through the whole deburring process in most cases)
  2. Enter the hole in a rapid move (G00)stopping approximately .040”/1mm before the blade makes contact with the workpiece allowing room for any burrs that may be present.
  3. Enter a controlled feed (G01) and feed into the part until the blade is fully collapsed into the pilot portion of the tool.
  4. Rapid through the part/material enough to allow the blade to fully elevate out of the pilot on the reverse side of the workpiece.
  5. Enter a controlled feed (G01) and engage the burr upon withdrawal of the tool until the blade is fully collapsed into the pilot.
  6. Rapid out of the hole to the clearance plane and move to the next location.
  7. Repeat from step 2

Our team offers CNC programming support for all types of CNC Horizontal/Vertical Mills, Standard Lathes, Swiss-style lathes, and screw machines to ensure proper tool operation and to help with minimizing cycle times.

Ensuring Safety

While deburring is a routine task, safety should never be compromised. Wearing appropriate protective gear, and adhering to manufacturer guidelines are essential safety measures. Additionally, keeping deburring tools out of the reach of children minimizes the potential for injury.

Mastering the art of deburring requires attention to detail, precision, and adherence to safety protocols. By selecting the right tool, properly assessing the workpiece, and properly executing the deburring process with care, you can achieve exceptional results.
