Meeting Stringent Requirements Deburring Ribs in a High Silicon Aluminum Engine Block

EZ Burr was tasked with deburring a series of internal ribs in a very long high-silicon aluminum engine block. A special extra-long (14” OAL) Carbide Series tool with a rear cutting only inserts was required to get down into the internal ribs for the deburring. 

​If that where the only parameters to that need to be met it would be a challenge.  The customer also needed cycle time to remain at 12-15 seconds while running at 1250 RPM and 15.750" IPM. 

EZ Burr had to make an extra length tool that could handle these cutting conditions without adding any cycle time to the process. The insert had to produce a clean, smooth surface and run a consistent number of blocks each and every shift.

The initial testing resulted in a built up cutting edge on the inserts. EZ Burr's solution involved working closely with thier coating vendor to apply the perfect coating to the inserts to get the desired results.

​In the end, the tool design, cycle time and performance all met the stringent requirements as specified by our customer. We also made sure to always have a batch of these specially coated inserts ready for release at our local distributor, and enough long reach arbors on hand at EZ Burr to have ready to deliver in less than 2 weeks.
