- Replaced hand polishing with burnishing
- 22 minutes saved per part
- 0.2Ra surface finish achieved (Even better than required)
- Safer process
Challenge
A manufacturer needed a better means of achieving the 0.5 Ra finish they required on their parts made out of a high tensile steel. Previously, this was accomplished by a turning operation followed by hand polishing to achieve the required finish.
Using
Material: High tensile alloy steel S355J2+N
Machine: CNC Lathe
Part Specifications: Ø240mm x 385mm long
Finish Required: 0.5Ra
Turning Operation: 245m/min F0.30
Finishing Operation: Hand Polishing/Abrasive paper 30 minutes per part
Solution
The Monaghan team proposed the use of an Elliott OD Carbide Roll Burnishing Tool S2075-00M in order to consistently produce the surface finish needed and reduce the total cycle time.
Burnishing speed: 245m/min Feed: 0.15mm/rev Diameter reduction: 0.02-0.03mm Time Saving: 22 minutes per part in 1 operation
Final Result
With the Elliott OD Carbide Roll Burnishing Tool, the company was able to produce a significantly finer surface finish on a consistent basis. The company no longer needed to hand polish and was able to finish the part within the CNC automated cycle.
Replaced hand polishing with burnishing
22 minutes saved per part
0.2Ra surface finish achieved
One process
