Project Synopsis

CNC based Automation of Nut runner Machine for Engine Oil Pan. There are 36 nuts which are tightened automatically using Renault Nut Spindles. The Spindle is controlled by a dedicated controller where the tightening torque in monitored. the communication between the spindle controller & CNC was hardwired. The position of the individual nuts is predefined in the Part Program of the CNC. The vertical & horizontal positioning of the spindle is done through CNC part programs. The feed rate is operator adjustable. The current status of the machine is indicated by LED based MIMIC.
