Choosing a Deburring Method

How to know which deburring method is right for your application

There are many ways to deburr parts - from manual hand held tools to fully automated, lights out processes. Which is your best option? The answer is usually best answered after determining the following: Which method best achieves the lowest cost per piece produced AND meets your part quality and throughput requirements?

Considerations to help you determine the best deburring process for your application


How many pieces do you have to process, and / or will this job repeat on a regular basis?

What is the timeframe to complete the deburring process without adversely affecting throughput, work in process flow, customer deadlines, etc

Do you have machine time available to add the deburring process?

What is the value of the part and what is the total cost of poor quality if the deburring process is inconsistent? Total cost includes scrap of the part, missed production deadlines, rework, customer complaints, etc.

Does the method increase costs from injuries resulting from cuts and repetitive motion injuries?

Is sufficient manpower available to complete the parts in the required timeframe or are resources available to implement the process such as machine programming?

What is the cost of the actual deburring tools used in the process?

Does the process produce the required surface finish requirement?

For on machine processes- how many pieces can be produced without stopping the machine to change deburring tools?

Does the machine tool part orientation / fixturing allow access for the deburring tool?

Overview of the pros and cons of various deburring processes

Automated Deburring Methods

  CNC / Robotic Deburring
  On machine deburring using
Xebec ceramic fiber brushes and stones
On machine deburring using
nylon impregnated fiber brushes
On machine deburring using
Xebec BackBurr Cutter and Path
PROCESS OVERVIEW Deburring surfaces or crossholes using Xebec brushes and stones in machine tools or robots including automated / lights out operation Deburring surfaces using nylon impregnated brushes in machine tools or robots  Designed specifically for hole deburring, the Back Burr Cutter and Path consists of the spherical cutter specially designed for CNC deburring using the customized path data.
PROS  Longest tool life; greatest part quantity produced per tool  May be justified for smaller production quantities  Enables uniform edge shape
   Maintains shape providing consistent, repeatable quality  Lower initial price than Xebec  Customized Program created for each application
   Fastest machining time  Greatest variety of tool configurations & sizes  Long lasting carbide with specially designed coating
   Best surface finish; polishing   Abrasive grains embedded in fibers grind on sides and ends  Helical blade prevents secondary burrs
   Surface / crosshole deburring of materials up to 65Rc    
CONS  Higher initial tool cost than nylon; best suited for production machining  Inconsistent grinding performance  For hole deburring only
   Limited availability of specials  Relatively long machining time  Best utilized with custom path
   Cutting action only on end of brush fibers (stones cut on entire surface)  Average surface finish  Information about application required prior to path creation
     Nylon fibers deform over time  

 

Manual Deburring Methods

  Non-CNC
  Manual deburring by hand
or hand held powered tools
Automated deburring using centrifugal
and vibratory media machines
 
PROCESS OVERVIEW Employee uses abrasives, tools, blades, etc to manually, or use hand held powered tools, to remove burrs after machining process A separate piece of equipment is designed to tumble metal parts and components to polish and deburr them to the desired finish. Abrasive material is typically added to the tumbler to improve the process.  
PROS  Lowest initial cost for tools  Automation of edge-finishing and surface polishing  
   Requires no machine tool time  Consistent, repeatable quality  
   Deburring can possibly be performed internal to machining process time  Can process large quantity of small parts  
CONS  Inconsistent repeatability  High equipment cost or outsourcing  
   Poor quality; high scrap  Additional floor space required  
   Requires manpower; can be time consuming creating production bottleneck  Separate process after CNC, can be time consuming   
   Possible employee injury from repetitive motion or cuts  Not optimal for hole deburring

Safety Warning

Cutting fiber brushes and stones are cutting tools and are often rotated at high speeds with a power tool or in a machine tool. They should never be operated at higher than the maximum speeds listed. When using these tools, safety glasses and gloves should be worn. Breathing the dust created by using these products for prolonged periods of time should be avoided.
