    Abstract
    The CJK6032 numerically controlled lathe including bed,way system,headstock and spindle,turret construction,tailstok,and work holding device. The asynchronous motor and frequency conwerter connect with each other, thus get have frequency control of motor speed.Horizontal enter to with enter lengthways to all from tread with power to arouse into the electrical engineering, is pass by the electrical engineering to double roller chain couplingto arouse horizontal enter to with enter lengthways to, but its pulse equivalent want to be small in the 0.005 mms, because of choose to tread to tread to be apart from Cape to 0.36 into the electrical engineering, past the step enter electrical engineering and double roller chain couplingto still need to use to spread to move to compare to 1:2 of decline soon wheel gear. The feed movement from tread to arouse into the electrical engineering, pass to decline soon wheel gear to spread to double roller chain coupling, arouse the cutter to do the feed movement.
    Keywords: numerically controlled lathe; frequency conwerter; double roller chain coupling
