«By using the URMA reamer, we could reduce the processing time of the component by one third. This is simply ingenious!»
With the company Franz Kuenzli AG in Wangen b. Duebendorf in Switzerland, we have already been able to realize some interesting reaming applications. These applications have been manufactured in a wide variety of materials such as aluminum, steel, copper, etc. In the present application, the process time could be reduced by 90% with the help of the URMA RX medium.
In a request from Mr. Krawinkel to optimize a running component made of PMMA (acrylic glass), we were asked to optimize the roughing of a bore ø16.5mm to ø17.0mm using a high performance reamer. The process for producing a measuring cylinder for laboratory use was previously as follows: drilling ø16.5mm / roughing ø17.0mm / finishing (finishing) to ø17.3mm using an MKD tipped insert. The tool was assembled with standard
components from the URMA RX medium Reaming System and equipped with a coated carbide insert. When running in the new URMA reaming tool, we quickly realized that we could not only reduce the machining time many times over, but that the surface quality of the bore was also significantly improved.
The surface could be improved from boring (Ra 0.38-0.42μm / Rz 2.1-2.3μm) to reaming (Ra 0.08-0.12μm / Rz 0.8-1.0μm). Without further ado, the diameter of the reamer was adjusted to the finished diameter and integrated into the process. This step eliminated the need for roughing and reduced the overall process time by 90%. In addition to the savings in machining time, the optimization is also characterized by the process reliability on the diameter and the improved surface roughness, which also halves the time required for subsequent polishing of the workpieces.
