DETROIT CNC’S DTC 250B series CNC Turning Centers are the best machines in the market for mixed volume, short-run or dedicated high-volume applications.


The ribbed Meehanite cast iron mono-block casting – 45-degree true slant bed box way design prevents machine’s deformation and vibration during heavy duty machining.


The DTC 250B features an A2-6 spindle nose, 8” hydraulic chuck, Ø2.56” bar capacity. The spindle motor is Fanuc 20 HP AC Servo motor with 4,000 rpm maximum spindle speed. The easy maintenance cartridge type spindle design with high precision bearings provide stronger support for heavy duty machining and/or interrupted turning. 


The 12-station turret has capacity for 1” OD shank and boring bar holders. Programmable tailstock with programmable quill and bar feeder interface are all standard accessories.

Best of all, DTC 250B comes with powerful FANUC 0i-TF CNC control and Fanuc AC servo drives and motors. This latest control provides most popular functions within his standard features, such as rigid tapping, multiple threads, plus the conversational Manual Guide Oi program. Fanuc 0i-TF is the most powerful and valuable control in its class.
