Arguably, equipment that can perform both milling and turning is more valuable to shops that machine large workpieces than those churning out smaller ones. There are a number of reasons why multitasking is particularly valuable for the type of work Magna Machine performs. The most notable is reduced handling of bulky parts on the shop floor that no longer need to be transferred to multiple machines. Setups are often easier, too, because parts can be oriented in such a way that gravity is more a friend than a foe. (This also means fixturing is more robust to withstand heavier cuts.) Finally, delivery times to customers can be greatly shortened. Setups for large forgings, castings and weldments can take an entire shift or more compared to just a couple hours for more conventional workpieces.

Magna Machine has three big multitasking machines in what it calls its “super bay.” One is a Union horizontal boring mill that can also turn parts thanks to the addition of a Bost rotary table installed at one end of the machine’s X-axis travel. See it in action in the video above, and read this story to learn more about the shop’s move to massive multitasking.



  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • When Cold Forming Threads Makes Sense

    Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
