Semi Automatic Drilling And Pinning Line


The line features 4 processing stations linked in series on a conveyor system. 7 bars are loaded manually at the first station, after which the bars feed to the second station equipped with a multi-spindle drilling machine fitted with a drilling head with 150mm stroke and 50mm of Hydro Feed Control, #2 Morse Taper Spindles. The drilling head has 7 ER20 Style spindles, 50mm centre-to-center pitch in-Line, with collets for 5mm drills. After drilling the 7 bars are fed to the 3rd station where pins are manually inserted into each drilled hole. At the 4th station the 7 pins are hydraulically seated to depth. The 7 bars are then fed of the end of the conveyor into a trolley.
