COLCHESTER MULTI TURN 3000 CNC LATHES

Technical Description

This CNC lathe features a robust 10.0-inch chuck size and a 3.0-inch bar capacity, powered by a 10 hp motor delivering up to 2,200 RPM with three infinitely variable spindle speeds ranging from 1 to 2,200 RPM. It offers a maximum turning diameter of 18.1 inches over the bed and cross slide swing of 10.6 inches, with a gap swing capacity of 28.7 inches and a machining length of 60 inches. The bed width measures 15.7 inches, complemented by a spindle bore and power supply of 3.0 inches and 230/460 V 3-phase respectively, with a D1-8 spindle nose taper (5 MT). The lathe’s X-axis (cross slide) travel spans 11.7 inches with rapid traverse at 315 in/min, while the Z-axis (saddle travel) extends 55 inches with a rapid traverse of 394 in/min, enabling precise and efficient multi-axis machining. The tailstock includes a 3.7-inch diameter quill with a 5.7-inch travel and a 6 MT taper to support long workpieces. Dimensionally, the machine measures approximately 142 inches long by 77 inches wide and 69 inches high, weighing around 8,000 lbs. Control is managed through an advanced Fanuc CNC system, facilitating operator programming and automation integration. The machine’s spindle nose, variable speeds, and substantial power make it suitable for a broad range of turning applications requiring precision, flexibility, and power in medium to large part machining.
