Ryazan RT 958 Special engine lathe

Ryazan RT 958 SPECIAL ENGINE LATHE Model 
The lathe is intended for machining of turbine rotor necks by turning with following finishing of the necks by changeable grinding heads of grinding carriage. When the lathe carriage is set on the machine it is possible to perform different turning operations including taper turning and thread cutting. Accuracy type of the machine is  increased accuracy. 2 carriages of the machine provide the machining of rotor necks without their resetting. The lathe is equipped with the drive and its increased moment is for the acceleration of a big mass part. The machine agility and the wide range of spindle speeds and feeds provide the full use of progressive cutting tools at machining different materials. Design features rigidity, vibration resistance and temperature of all gears of the kinematic chain are high quality stability of the construction allow for high steel, hardened and ground. accuracy of the lathe operation protective guard of cutting zone and a chuck, 3 prismatic bed ways are hardened and ground electrical and mechanical interlockings guarantee with high reliability of other units provide long safe operation of the lathe life of service with keeping the original accuracy lathe operation in grinding mode provides the 3 apron provides the rigidity at accuracy up to machining the workpieces of big diameter surface roughness is not below 9 class. kinematic chain of the feed gear box is very
