Edge Rounding Enhancement with DM1100 C

Edge Rounding Enhancement with DM1100 C

At our testing center, we recently conducted production trials with the DM1100 C machines to assess edge rounding and surface finishing techniques tailored to specific customer needs.
 

Test Objective


A customer requested tests to achieve the best possible edge rounding while ensuring the finish followed the direction of the longest side of the part. To ensure the most effective solution, we performed a comparative test using the Purple Radius Crossbelt abrasive. In the process, we applied the finish parallel to the longest side on one piece, while on the second piece, we positioned it diagonally to maximize the impact on all edges. Both pieces received finishing on both sides.
 

Customer Profile

 
The customer is a manufacturer specializing in the production of high-precision fastening systems for the automotive and construction industries, offering a range of innovative and reliable solutions for connecting and securing various components.
 

Testing Parameters and Process


Machine used: DM1100 C
 



The customer sent two samples with the same thickness (0.8mm), and the tests were conducted to find the best solution to meet their needs. The parts were labeled A and B to ensure a clear and objective analysis in the report.

On part A, we strictly followed the customer's request, rounding the edges on both faces with the lines parallel to the longest side of the part.
On part B, we applied our recommendation, positioning the piece diagonally on the belt to maximize the impact on all edges and optimize the final result.
Both parts were tested under the same conditions, with the feed rate set to 0.8 m/min and the crossbelt speed adjusted to 8 m/s, ensuring consistency and comparability of the tests.

Results and Best Performances


In the images, it is possible to observe that both parts achieved excellent edge rounding, meeting the customer's expectations thanks to the use of the Crossbelt Purple Radius abrasive. The difference in the finish between the diagonally positioned part (B) and the horizontally positioned part (A) is clearly visible.

Nevertheless, both parts show a similar level of edge rounding. It is important to highlight that all tests were carried out under the same feed rate and crossbelt speed conditions, ensuring consistency and comparability of the results.
