Work industry experience

       Work Experience @ EPITOM
 ‎
 ‎ Good morning everybody, now I am going to shear my story while work at EPITOM. The base plate or we can say pcb .initially in  company only single sided pcb  were manufactured but now double sided pcb also manufactured by company.
 ‎
 ‎      let's
 ‎I want to tell  day wise in sequencial format means mechanical work, all basic process during aur  job.
 ‎    At my 1 St  2 nd , 3 rd day
 ‎I got work in second ship ( 3 to 12)
 ‎Then completes my documentation process.
 ‎MR balaji sr was my guider and gave me work on  edge bevelling machine. During working on this machine I learn how to settings up machine on the basis of type of panel. We can adjust machine by rotating knob  in anticlockwise as for contraction and in clock wise for expansions clock wise movement of knob was their.
 ‎No of knobs : 3
 ‎Red for stop
 ‎green for start
 ‎and another 1 red is of emergency knob.
 ‎
Parts of machine :
Motor ,conver,belt drive,edge bevelling cutter.
Disadvantage  :
If any panel would not go in straight line then it will get damaged.


2. Sawing machine :
 Working -
 ‎purpose of sawing machine is to cut the panel by using cutter and range of its for cutting thicknesses is from 3 to 4 mm.
 ‎process  :
 ‎before  feeding the panel to machine 1 St of all we have to set scale dimensions and it depend on type of panel.
 ‎cutter of this machine is  in vertical position.
 ‎mostely big panels are cuts on this machine

Shearing machine :
 Panel is cuts into smaller blocks as pr dimention after the sawing machine.
 ‎the shape of cuttre is in cylindrical shape.

Scrubbing machines :
In this machine work piece is washed, clean,finished.

In all of the machine after setting up machine , 1 St 3 to 4 sample were checked by inspection master.
