ABSTRACT

With the development of industry equipment, the precision required of industry equipment is more and more high. The more and more precision of equipment which machined the industry equipment is required. But in China the common lathe have a very great comparison in the machined equipment, this already restrict the development of industrial nowadays. But the CN lathe is more expensive, and needed workers with higher technically. So it is a necessity very much to modify the common lathe to lathes automatic. This paper is in the foundation of the commonness horizontal lather CA6140 and modified it to Lathes automatic.
The author has performed the further research and for the lathes automatic modification on the basis of the constant consultation of abundant relative documents, which focuses on describing the design of control of the machine. Screw on the choice of friction loss, high efficiency, high precision, long life of the ball screw, the electrical selected stepper motor, motor and the ball screw with gear deceleration.The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of JKW-15T is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.

Key words: Machinery Tool Reform； Lathes automatic； Servo system
