What is Micro CNC Deburring?
CNC deburring, essential in precision machining, addresses the challenge of burrs left on workpieces after CNC machining. Manual CNC deburring involves hand tools like brushes or files, ideal for intricate parts or small batches. Automated CNC deburring uses machines or robots with grinding wheels or abrasive tools, and is more efficient for high-volume production, ensuring both speed and consistency.
The significance of CNC deburring lies in improving fit, functionality, and safety. Deburring ensures precise assembly by eliminating burrs that might hinder components’ fit or operation. Additionally, the process enhances safety by removing sharp edges, contributing to overall quality and meeting safety standards.
CNC deburring’s impact extends beyond functionality to aesthetics, providing a smoother surface finish that is crucial in industries where visual appeal is a high priority. Deburring is a versatile practice applicable to various materials and industries, promoting long-term cost-efficiency despite initial setup costs.

By-Hand Deburring Services
Normal CNC shops use machines to complete their deburring and polishing processes, resulting in machined parts with rough edges and tiny, uncleaned holes. The CNC machines at Koham Industries are anything but “normal.” We know deburring is as important of a process as the machining itself. For the highest precision, attention to detail and accuracy must be applied from the start of a job to its completion.
Koham Industries has applied this attention to detail to every component machined in our Wisconsin facility. Our deburring department has 30 X Power Magnification Microscopes at every deburring station, backed by trained employees skilled in microdeburring.

Benefits of Deburring
Deburring, or the process of removing burrs or rough edges from the surface of a workpiece, offers several benefits.
Improved fit and function
Burrs can cause issues with the fit and function of a workpiece, such as difficulty in assembling parts or interference with other components. Removing burrs ensures the workpiece fits and functions properly.
Enhanced safety
Burrs can be sharp and potentially dangerous, especially on components that are handled frequently. Removing burrs helps to reduce the risk of injury and improve the overall safety of the workpiece.
Increased efficiency and productivity
Burrs can cause delays in production and increase the time and effort required to assemble and use a workpiece. Removing burrs can help to streamline the manufacturing process and increase efficiency and productivity.
Improved appearance
Burrs can negatively impact the appearance of a workpiece, making it look unfinished or unprofessional. Removing burrs helps to improve the overall appearance of the workpiece and enhance its visual appeal.
Enhanced quality control
Removing burrs is an important step in the quality control process, as it helps to ensure the workpiece meets the required standards and specifications. This can help to reduce the risk of defects and improve customer satisfaction.
Types of Burrs
Several types of burrs can occur on the surface of a workpiece as a result of machining or other manufacturing processes.
External burrs
Burrs that protrude from the surface of the workpiece and can be felt with the fingers. External burrs are typically the easiest to remove and are often removed using hand tools or automated deburring equipment.
Internal burrs
Burrs that are located inside a hole or opening in the workpiece and are not visible from the outside. Internal burrs can be more difficult to remove and may require specialized deburring tools or techniques.
Edge burrs
Burrs that occur on the edges of the workpiece and are often caused by cutting or grinding processes. Edge burrs can be difficult to remove and may require deburring tools with fine or flexible points to access the burr.
Fillet burrs
Small, rounded burrs that occur at the corners or edges of the workpiece. Fillet burrs are often caused by the use of high-speed cutting tools and may be difficult to remove without damaging the surrounding material.
Flank burrs
Burrs that occur on the flanks, or sides, of the workpiece. Flank burrs are typically caused by the use of high-speed cutting tools and can be difficult to remove without damaging the surrounding material.

FAQ
Deburring FAQs
What is deburring and why is it essential in CNC machining?
Deburring is a critical post-processing manufacturing step used to remove unwanted raised edges, burrs, and sharp corners left behind on a workpiece after machining operations like milling, drilling, turning, or laser cutting. It is essential because burrs can interfere with part assembly, cause premature mechanical wear, create safety hazards, and degrade the overall aesthetic and functional quality of the component.
What is the difference between automated deburring and manual (by-hand) deburring?
Manual (By-Hand) Deburring: Relies on skilled technicians using specialized hand tools, files, scrapers, or miniature power brushes. It offers unmatched precision and tactile feel, making it ideal for delicate, complex geometries, fragile features, and high-value custom parts where perfection is required.
Automated Deburring: Utilizes advanced machinery—such as mass finishing tumblers, robotic brushes, thermal deburring, or electrochemical processes—to process high volumes of parts quickly and economically with consistent repeatability.
What types of materials and parts benefit most from professional deburring?
Virtually all metals and high-performance plastics benefit from deburring, especially components used in mission-critical applications. Parts with internal channels, intricate threads, sharp cross-holes, and tight-tolerance aerospace, medical, or automotive components require meticulous deburring to ensure optimal fluid flow, proper sealing, and stress distribution without altering critical dimensions.
Can deburring affect the dimensional tolerances or surface finish of a precision part?
When performed by experienced technicians using controlled techniques, deburring targets only the microscopic burrs and sharp edges without compromising the part’s core dimensional tolerances. In fact, professional deburring improves the overall surface finish, reduces friction, eliminates stress concentration points, and prepares the metal or plastic surface for subsequent treatments like anodizing, plating, or passivation.
How do I know if my machined components require specialized deburring?
If your parts are subjected to high mechanical stress, high-pressure fluid dynamics, or strict aesthetic and safety standards, professional deburring is usually a necessity. You should review your part drawings for critical edge-break callouts (e.g., “break all sharp edges 0.1–0.3 mm”) and discuss your assembly requirements with your manufacturing partner to determine the most effective finishing method.
