FEATURES:
This is a high precision CNC flat bed lathe with FANUC Oi-TD control. The STC series is available with option of 6", 9", 12" or 15" spindle bore, 38" to 60" swing over bed and 79" to 197";distance between centers. The bed width is 49" and the spindle motor is available up to 100 HP.
The CNC Big Bore Lathes feature a unique design of one piece casting base that allows heavy cutting with high precision. The hardened and ground bedways are made from high quality Meehanite castings with internal ribbings for vibration dampening, heat distortion prevention and long lasting stability. There are 4 levels of geared spindle speeds to deliver full torque under various speeds. Change of each level is commanded by M code, operated hydraulically. Bedways and ballscrews are centrally lubricated with low level alarm. Headstock is equipped with heat exchanger to disperse heat and maintain spindle accuracy. Full length chip conveyor and enclosed splash guard are all standard accessories.
