Sliding headstock type cam automatic latheC-7
Years of production 1957 - 1970
The C-7 is a developed version of a prototype cam-type automatic lathe that was designed during WWⅡ. Today, there are still a number of the machines in operation at the in-house facility of the Citizen Group. Tools are arranged radiating out from the guide bush and lateral and longitudinal movements are controlled by independent cams; realising complex machining without using form tools. Utilising its three spindle drilling attachment the machine can also perform end face drilling.
