Cam-Free Multi-Spindle Lathes: Sometimes Simple is the Best Choice
August 14, 2012
If your CNC machining operation doesn’t require multi-spindle lathes capable of completing very complex parts, and you’d like a more affordable alternative with excellent accuracy and faster changeovers, Gosiger has a solution: The Shimada line of cam-free 6- and 8-spindle lathes, available in 16 mm, 27 mm and 32 mm bar size capacities.
These lathes incorporate two, 2-axis NC slides in the 4th and 5th position plus automatic compensation to provide precise, single point OD, ID and facing capability. Shimada includes the same system in its 6- and 8-spindle chuckers. The 6-spindle chucker has 60 mm collet capacity and 5” chuck capacity. The 8-spindle version has 32 mm collet and 4” chuck capacities. Both include single or double part cycling, simultaneous, alternating front and back machining and spindle stop capabilities.
Also from Shimada are 2-spindle chuckers in 6”, 8”, 10” and 12” chuck sizes that allow simultaneous machining and part loading and unloading. Adding an integrated robot for this purpose enables users to easily accommodate increases in production volume.
