Marubeni Citizen-Cincom will introduce its L20 Type XII Swiss-type lathe featuring B-axis controllable rotary tools. According to the company, this additional axis of control facilitates the drilling and milling of angled features and contours without retooling or resetting, with a total range of 135 degrees, from +90 to -45 degrees. Rotary tools can be used for both front and back machining. The lathe also offers the flexibility of operating with or without the guide bushing. The guide bushing is installed for machining long, thin workpieces and is removed for the machining of shorter pieces or short bar remnants.
The spindle offers a 26-mm through-hole diameter. Spindle speed of the gang rotary tools ranges to 6,000 rpm, while the spindle speed of the back toolpost roatary tools range to 7,500 rpm. The gang toolpost accommodates 26 tools, raising the machine’s total possible tools from 39 on previous versions to 40. The lathe’s power consumption has also been reduced from 8 to 7.3 kVA.
