COLCHESTER HARRISON TORNADO T6MS CNC turning centre was built in 2007 in the United Kingdom. A highly reliable lathe used for a wide range of workpiece machining with a maximum diameter of 220 mm, uses driven tools and extensive equipment to achieve excellent accuracy of surface finish in such operations as drilling, boring and threading.
A solid cast iron bed set on a structure filled with specially developed polymer concrete achieves accuracy as well as thermal and dynamic stability during turning of up to 300% greater than cast iron. Turning takes place in the fully illuminated machine workspace equipped with a powerful 15 kW main spindle and a sub spindle that rotates at a maximum speed of 6000 rpm. This solution allows for automatic transfer of the workpiece between the two spindles in order to continue turning, milling and drilling on the other side of the workpiece.
The TORNADO T6MS CNC lathe has a wide range of equipment, including e.g. a bar feeder to increase productivity during longer production runs, a state-of-the-art FANUC Series 18i-TB CNC control for convenient input of machining parameters and machine control, a 3-jaw hydraulic chuck and a 12-position tool head. The automatic lathe weighs approximately 4500 kg
