Turning Center Handles 4,500-mm Shafts Requiring Longitudinal Bores
WFL has redesigned its M40 Millturn for turning parts ranging to 520 mm in diameter, featuring an optional 4,500-mm center distance to enable efficient machining of longer, thinner shaft-type parts that require deep, longitudinal bores. Design improvements aim to increase reliability and user-friendly access of the tool magazine, along with other ergonomic changes. The redesigned operator panel now has improved ergonomics for shifting, improved access to the integrated printer, more space for optional control elements, optimized cabling and improved serviceability.
A key advantage, according to the company, is the enlarged steady-rest space, the result of an improvement in the layout of the energy chains. A positive secondary effect of this is a longer service life and increased reliability of the energy chains.
A separate pickup magazine is available for very long and/or heavy tools. The maximum tool length has been increased from 1,500 to 1,700 mm. The disc magazine can be extended to as many as 200 stations. Direct access to all tool stations is still possible even when using this extended magazine option, avoiding cumbersome loading and unloading. In addition, reliable optical sensors have been installed in the tool magazine for toolstation monitoring.
The additional rotary milling axis on these machines allows them to complete many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, eases the programming challenge significantly.
Combining a rotating tool with rotating work produces a machining operation that is distinct from standard turning or milling.
Old-world craftsmanship combines with precision machining on a vertical machining center and Swiss-type lathe to produce some of the only U.S.-made mechanical wristwatch movements.
