Yes, there are ways to prevent burrs. The first consideration should be to identify what is causing the burrs to form. If the burr isn’t caused in the first place, you don’t need to remove it. That isn’t always possible. If preventing burrs from forming isn’t a possibility, you would want to look at options that will minimize the formation of burrs or isolate the formation in an area where removing burrs is easier.
Ways to prevent burrs:
- Use formed or extruded parts rather than machined parts
- Cast instead of machining edges.
- Use form tools rather than tools that face and turn.
- Use a process like chemical machining when possible.
- Use ultra-high-speed machining when possible.
- Try to prevent cutters from exiting from the part.
- Use selective hardening (flame hardening, induction hardening, laser beam hardening or electron beam hardening) to reduce ductility at the edges.
- Use a sacrificial backup material
- Plan and allow for large exit angles on edges of parts
- Use push-back blanking method (best for aluminum, mild steel or stainless steel)
Minimizing and preventing burrs continues to be a challenge for any industry. ISO Finishing understands these challenges. That is why they have spent countless hours becoming experts in deburring services.
Why is deburring important?
The formation of burrs can sometimes be prevented. Burr removal can be a nuisance within any industry. They can cause serious problems if they are not properly removed by a deburring service. A few of the specific industries that rely on high-quality precision finishing are medical, dental, aerospace, automotive, firearms, and military. Depending on the industry, burrs can cause several problems such as inefficiencies, product quality, proper functionality and optimal performance. Surface quality is a major focus for any industry where performance, safety, appearance, and cost of the part is a concern.
Are there different methods of deburring services?
Yes, mechanical deburring services encompass many types of processes, including:
- manual deburring
- cryogenic deburring/deflashing
- cutting processes
- electrochemical deburring
- thermal deburring
- power brushing
- bonded abrasive finishing
- mass finishing (vibratory deburring or centrifugal barrel deburring)
- abrasive blasting
- abrasive flow deburring
