precision, for metalworking


Cylinder bores, camshaft bearing and crankshaft bearing bores are of key importance for every engine manufacturer. Efficiency, smooth running and low-wear operation of the engine depend on the quality and dimensional accuracy of these machining processes. Liebherr in Switzerland as an end customer successfully relies on the tool competence of LMT Tools in its segment Advanced Tooling. The customer uses the latest generation of motion tools and line boring bars from LMT Kieninger for the machining of cylinder blocks in V12, V16 and V20 engines. With these tools the processing time and precision can be optimized successfully whilst at the same time reducing production costs. Machining takes place on cylinder blocks from the material CGI (Compacted Grahpite Iron) on machines from Burkhardt & Weber Reutlingen, type MCX 1200 and MCX1400. For the finishing of the cylinder bores, motion tools are used which perform the high precision machining of the unsupported bearing surface including an axial and radial insertion in bump off process with an internal tie rod.
