JOB ROLE

The breakdown cost of CNC machines and other Mechatronics systems is very high. The role of Mechanic Mechatronics is very important in the industry to keep the breakdown cost to minimum.
The job roles expected from Mechanic Mechatronics is described below:

• To repair and maintain CNC machines and other Mechatronics systems in working condition.
• To analyze the alarm messages displayed by the CNC system, to take backup of NC/PLC / Drive data, to install drives (axis & spindle) and to initiate necessary action to solve the problem.
• To establish communication between the CNC controller & PC through Ethernet Port, create new alarm msgs and read the various machine parameters
• Read and understand the circuit diagrams of hydraulics, pneumatics, PLC system, electrical and electronics to analyze the problem for solution.
• To coordinate with the production section to ensure strict adherence to the daily, weekly, quarterly maintenance schedules of the CNC machines and other Mechatronics systems to avoid costly breakdowns.
• To plan and execute preventive maintenance of CNC machines and other Mechatronics systems to avoid breakdowns.
• To dismantle Mechatronics systems like spindle assembly, ball screw, gear box, feed mechanism, lubrication system, coolant system, feedback devices, check different parts, make necessary repairs and reassemble the systems.
• To check the repaired and reassembled systems for proper functioning and fit them in the machine.
• To advice management in maintenance of necessary spares inventory of CNC machines to reduce breakdown time.
