CNC Experience:

I have three and a half years of passive CNC experience, It wasn’t my main workload but I am hardworking and a quick learner with determination to increase my skill set. I’ve worked with brands such as Haas, Mazak, DMG Mori, Okuma. I’m confident with operating lathes; Machine Control Unit (MCU), the drive system, the machine tool assembly ( Spindle, tool changer, and cutting tools), the workholding system, the machine bed or structure, the feedback system, and the coolant system.
