Knuth’s Numturn CNC cycle lathe features a heavily-ribbed machine bed with guides and wide V blocks. It is available with either a Siemens or Fagor CNC, but can also operate as a manual lathe via handwheels.
The lathe’s spindle bearings and headstock are designed to ensure constant precision during continuous operation. Other features include a hydraulic chuck with adjustable holding force, a heavy-duty tailstock, a multi-tool VDI tool turret, a central lubrication system, electronic hand wheels and operating tools, and the capability of positioning accuracy in the thousandth-of-an-inch or ten-thousandth-of-an-inch range. Swing distances ranging from 13" to 26" and center distances ranging to 79" are available.
Machine tool builders in Korea have been playing a catch-up game for the past decade. A review of current developments in machine tool technology indicates that Korea is rapidly pulling up with manufacturers in Japan, Europe and the United States. The products from Korea closely match their counterparts from other global suppliers in terms of capability and quality.
Form tools are traditionally associated with non-CNC machines, but in certain applications they make sense on modern machines as well.
Finding a way to fixture contoured marine propellers proved to be this shop’s biggest challenge in developing an effective automated machining cell.
