As the energy sector continues to advance, efficient and high-precision methods of producing components are a crucial aspect. One area that requires special attention is the machining of crankshafts. WFL Millturn Technologies is responding to this need by offering advanced solutions for the complete machining of crankshafts in small series.
“A MILLTURN provides the best alternative to conventional production methods for the complete machining of crankshafts, including deep hole drilling of oil ducts or gearing,” said a company spokesperson. “Based on many years of experience and the use of flexible and multifunctional complete machining centers, WFL can produce prototypes and small series of crankshafts efficiently. Whether for high productivity rough turning or precision pre-finishing—all crankshaft geometries can be completely machined in a MILLTURN from WFL.”
High Potential for Savings
The complete machining of crankshafts requires maximum accuracy and reliability. Conventional methods use several steps to machine crankshafts, with various specialized machines and processes coming into play. While this approach delivers a high output, it lacks flexibility and is therefore only suitable for large series. The production of crankshafts is a highly complex and relatively inflexible process on highly specialized machines designed for series production and on all-purpose machines for small series and prototypes.
The use of MILLTURN complete machining centers together with efficient technologies allow WFL to combine the entire machining process in one machine in just a few clamping operations. WFL machines can handle all the steps required to produce a crankshaft. A single machine carries out milling, boring, turning, deep hole drilling and measuring—from blank to the nearly finished product. In addition to reducing production time, this also enhances the quality and precision of the crankshafts. Final heat treatment and the grinding of the crankshaft bearing and crankpin are the only separate processes.
Complete machining eliminates the time-consuming process of moving between different machines and the set-up time this involves. This significantly boosts production capacities and reduces overall costs. At the same time, the machine’s high level of precision minimizes the risk of errors and enables the consistent quality of the crankshafts due to measurements carried out in the machine.
“The potential for savings is considerable when machining crankshafts in a MILLTURN compared with conventional production on multiple machines. A 60% saving can be achieved in the process chain thanks to complete machining, and this figure is even 80–90% for the set-up time,” said the spokesperson.
Cranx: the Crankshaft Profiler
Machining crankshafts is a demanding process that not only requires quality tools but also the relevant software to be successful. WFL’s cycle packages make crankshaft machining especially simple and cost effective. These cycle packages contain cycles for pre-roughing crankshaft bearings and bearing grooves, a web milling cycle and rounding of oil holes with radius cutter or corner rounding end mill.
