From General Fitter to Specialized Technician: The Career Evolution
A mechanical fitter knows mechanical systems broadly. A maintenance technician specializes deeply in one area: CNC machines, hydraulic systems, electrical systems, automation equipment, or pneumatic systems.
Specialization is where earning power multiplies. A general fitter earns ₹25,000-35,000/month. A CNC machine specialist earns ₹35,000-50,000/month. A robotics technician earns ₹40,000-60,000/month.
Why? Because specialized knowledge is rare and valuable. When a ₹50 lakh robotics arm malfunctions, any technician can’t fix it. You need someone who understands that specific system deeply.
With automation and robotics adoption accelerating in Indian manufacturing, specialized technician roles for CNC, robotics, and automation systems are in severe shortage, driving premium salaries.
